Wolseley Hornet (1961-69) Engine 998cc S4 OHV Production 28455 (all series) Registration Number KLJ 415 E WOLSELEY SET www.flickr.com/photos/45676495@N05/sets/72157623738922097... From its outset the Mini spawned many models that targeted different markets. Built as more luxurious versions of the Mini, both the Wolseley Hornet and the Riley Elf had longer, slightly finned rear wings and larger boots that gave the cars a more traditional three-box design. Wheelbase of the Elf and Hornet remained at 2.036 m (6.68 ft), whereas the overall length was increased to 3.27 m (10.7 ft). This resulted in a dry weight of 638 kg (Wolseley) 618kg (Riley). Mechanical specification was the same as the Mini but they feature wrap around rear bumpers, heater, screenwash and a wind tone horn. The first series was powered by a 949cc S4 OHV version of the BMC A series engine The second series 1963-64 introduced the larger 998cc version on the BMC A series engine and twin leading shoe front brakes. The series three 1964-69 gets Hydrolastic suspension, a diaphram clutch and key starting and from 1966 AP Automatic suspension became available.

The JF-17 Thunder or also known as the CAC FC-1 Xiaolong meaning the Fierce Dragon is a lightweight, single-engine multirole combat aircraft that has been manufactured after the joint efforts of the PAC (Pakistan Aeronautical Complex) and the CAC (Chengdu Aircraft Corporation) of China. The primary roles of the JF-17 Thunder are to be used for the following mission types. Aerial reconnaissance Ground attack Aircraft interception The aircraft has been named as JF-17; JF standing for the Joint Fighter-17’ by Pakistan. As for its Chinese designation FC-1 Xiaolong, it means ‘Fighter China-1 Fierce Dragon”. The JF-17 is equipped with both air-to-air and air-to-surface missiles as well as a 23 mm GSh-23-2 twin barrel Autocannon. The JF-17 Thunder is powered by either one Guizhou WS-13 or Klimov RD-93 afterburning turbofan engine that allows it to have a max speed of Mach 1.62. The JF-17 Thunder since its inclusion in the Pakistan Air Force (PAF) has become the backbone of the aerial force as it complements the features of the General Dynamics F-16 Fighting Falcon at half the operating costs. The first squadron of the JF-17 Thunder was included in PAF’s service back in February of 2010 and in 2015, Pakistan manufactured another 16 JF-17 Thunders to add in their aerial force. According to the reports of PAF, Pakistan is steadily adding at least 25 of the JF-17 Thunders on yearly basis since 2015. 58 percent of the airframe is Pakistani while the remaining 48 percent is Chinese or of Russian origin. Pakistan has currently 103 operating JF-17 Thunders in active duty with 70 being sued for Block 1 Type while the remaining 33 being used for Block 2 type. There is also news that Pakistan is planning to introduce a two-seater variant with designation JF-17B for their enhanced aerial fighting capabilities as well as for training purposes. The aircraft since its inclusion in PAF has completed a total of 19000 operational flight hours. The aircraft saw a substantial combat action from Pakistan in the “War in North-West Pakistan”. Pakistan is also going to export a fleet of JF-17 Thunders to Nigerian Air Force who will use it for military operations against the militant forces operating in Northern Nigeria. For our readers today, we have gathered a bunch of amazing facts about the JF-17 Thunder which are as follows. Development:- The development of the JF-17 Thunder started with the development of the Super-7 aircraft design by China for a 500 million dollars contract back in 19866. However, the development program was canceled due to financial and political reasons. The devolvement of the aircraft started once again in 1991 in China under the project name “Fighter China”. Pakistan and China jointly stated this program and signed a MoU (Memorandum of Understanding) back in 1995 to manufacture this aircraft. The preliminary design of the aircraft was ready by 2001 while the first original prototype was completed back in September of 2002. The production of the aircraft in masses started by 2003 after the design flaws were detected during the first test flight back in May of 2003. Two seat variant:- Pakistan is currently working jointly with CAC (Chengdu Aircraft Complex) on manufacturing a  two-seater brain that will not only enhance the fighter capabilities of the aircraft but will also be used for training purposes. The pans to manufacture this two-seater variant “JF-17B Thunder” was announced back in February of 2012. Cockpit:- The cockpit of the JF-17 Thunder is made of glass with a specially designed canopy that comes with the following features. three multifunction displays (MFD) head-up display (HUD) 32-bit weapon mission management computer (WMMC) a hands-on throttle and stick in between the MFD and HUD, there is also a UFCP (Up-Front Control Panel) to overcome the fog-up error that usually occurs in the humid, subtropical and tropical environments. To provide the pilot with all-round clear visibility; an acrylic canopy is installed to cover the cockpit. Avionics:- The following avionics have been installed in the JF-17 Thunder for ease of control. electronic flight instrumentation system (EFIS) a flight control system (FCS) health and usage monitoring system (HUMS) automatic test equipment UHF / VHF communication radios simpatico data links inertial navigation system (INS) an identification friend-or-foe (IFF) transponder Countermeasures:- The JF-17 Thunder is equipped with a countermeasure system named DAS (Defensive Aids System) that also comes with the following systems as well. radar warning system (RWS) missile approach and warning system (MAWS) a countermeasure dispensing system a self-protection radar jamming pod Radar:- The initial fleet of 42 JF-17s of Pakistan was equipped with NRIET KLJ-7 radars. The NRIET KLJ-7 radar is able to detect simultaneously ten targets through its track-while-scan mode that are located BVR (Beyond Visual Range). Engine:- The JF-17 Thunder is equipped with either the Klimov RD-93 or Guizhou WS-13 turbofan engine. The Klimov RD-93 I able to produce a maximum dry thrust of 49.4 kN and an afterburner thrust of 84.4 kN. As for the Guizhou WS-13 turbofan engine, it produces an afterburner thrust of up to 86.36 kN. Fuel tanks:- The fuel system of the JF-17 Thunder is an internal one which makes it able to carry internal fuel tanks with a maximum capacity of 2330 kilograms. These tanks are fueled by the single-point-of-pressure refueling system and are also equipped for IFR (In-flight Refueling). Speed and Range:- The maximum speed of the JF-17 Thunder is Mach 1.6 or 1909 kmph while the range of the aircraft is measured to be 2037 kilometers or 15240 meters with an operational radius measuring to be 1352 kilometers. Service:- Since 2010, when the first fleet of JF-17 Thunder was presented for active duty in the PAF, the aircraft has completed 19000 operational flight hours and has been a great help to suppress the militant and terrorist forces in the “War in North West Pakistan”.

Description The Chengdu J-10 (traditional Chinese: 殲十; simplified Chinese: 歼十; pinyin: Jiān Shí, meaning "Annihilator (Fighter) Ten") is a multirole fighter aircraft designed and produced by the People's Republic of China's Chengdu Aircraft Industry Corporation (CAC) for the People's Liberation Army Air Force (PLAAF). Known in the West as the "Vigorous Dragon",[4] the J-10 is a multi-role combat aircraft capable of all-weather day/night operation. The J-10 next-generation fighter program remained unknown outside of a China until December 29 2006, when the Xinhua News Agency officially disclosed its active duty status with the PLAAF Development The program was originally backed by the Chinese paramount leader Deng Xiaoping, who authorized half a billion Renminbi to develop an indigenous aircraft, but the official program did not start until several years later in January 1986 when the Chinese government officially issued Project #10,[1] to develop a fighter to counter new fourth generation fighters then being introduced by the USSR (namely, the MiG-29 and Su-27). The 611th Institute, also known as Chengdu Aircraft Design Institute was tasked as the main developer, with Mr. Song Wencong, the chief designer of J-7III assigned as the chief designer, and Mr. Xue Chishou (薛炽寿) as the chief engineer. Initially designed as a specialized fighter, it was later remade into a multirole aircraft capable of both air to air combat and ground attack missions. However, a Chinese children's magazine (zh:少年科学画报, ISSN1000-7776) published in June 1979 showed a boy holding a model of an aircraft similar to the J-10.[5] The picture indicated that the project began long before 1979. Although the existence of J-10 has long been reported both inside and outside of China, the Chinese government did not officially admit so until January 2007, when the first photographs of the J-10 were allowed to be published to the public by the Xinhua News Agency. Having been designed under such secrecy, before its official disclosure, many details of the J-10 were subject to much speculation. However, the rumored crash has been openly denied by the government of China after the official governmental acknowledgment of the existence of the J-10: on 1 January 2007, both the Xinhua News Agency and the PLA Daily have claimed/reported the accomplishments of one of the test pilots of the J-10, Mr. Li Zhonghua (李中华), and, in these reports, one of the accomplishments quoted was that there was not a single crash since the project began. According to Chinese media reports, the first plane, "J-10 01", rolled out in November 1997, and the first flight of "J-10 01" was on 23 March 1998.[1] No incident has been reported.[6] After 18 years in development, the J-10 finally entered service in 2004.[1][7] The aircraft made its successful maiden flight on 23 March 1998, flown by test pilot Mr. Lei Qiang (雷強), lasting twenty minutes. Another test pilot Mr. Li Zhonghua (李中华) test flew the prototype for its aerodynamic performance that lasted till early December, 2003, during which aerial refueling tests were also successfully completed. In these aerodynamic tests, the aircraft was pushed beyond its parameters of the original design and it was discovered that the aircraft could easily withstand the greater requirements. The last part of the test flight was the live round air-to-air missiles test firing, which lasted from 21 December 2003 to 25 December 2003, which was completed by test pilot Mr. Xu Yongling (徐勇凌). The aircraft were first delivered to the 13th Test Regiment on 23 February 2003. The aircraft was given the status 'operational' in December of the same year. The first operational regiment was the 131th Regiment of the 44th Division. It is rumored that a regiment of the 3rd Division has also J-10s. [edit] Export customers So far the J-10 has been offered only to Pakistan for export as the FC-20. Former President of Pakistan, General Pervez Musharraf, was shown the secret J-10 & JF-17 production facility in late February 2006. He also sat in the cockpit of both aircraft. On his way back he told the press that he had visited the J-10 production facility and that the Chinese had offered to sell the aircraft to Pakistan. He later said that Pakistan and its air force will certainly consider the offer. On 12 April 2006 the Pakistani cabinet approved the purchase of at least 36 J-10s under the designation FC-20. In a recent interview, Air Chief Marshal Tanvir Mahmood Ahmed said that additional FC-20 aircraft will be procured. On March 7 2009, at agreement signing ceremony of JF-17 Thunder aircraft, Air Chief Marshal Tanvir Mehmood Ahmed said the agreement between Pakistan and China for the delivery of High-Tech aircraft J-10 was intact and these aircraft after improving them further would be delivered to PAF in 2014-15. He said these aircraft are being modernized in accordance with the PAF’s requirements and delivered under the title of FC-20. Pakistan is the largest importer of Chinese military hardware. Its air force flies over 180 F-7 aircraft made by China. In addition, Pakistan is a 50% partner in the FC-1/JF-17 Thunder and K-8 Karakorum advanced jet trainer projects.[8] In April 2006, the media reported that the Pakistani government intends to procure at least 36 J-10s (designated FC-20 or FC-10, depending on the report). The Business Recorder claims that the Pakistani official document it obtained said the Cabinet "has allowed PAF to set up Joint Working Group (JWG) with CATIC for procurement of 36 FC-20 aircraft". Other media reports cited Pakistan Information Minister Sheikh Rashid (at that time) saying that the Cabinet has approved the purchase of J-10s from China, in addition to JF-17s.[9][10] On 31 March 2007, Pakistan Air Force Chief of Air Staff Air Chief Marshal Tanvir Mahmood Ahmed said, "PAF would soon induct fourth and fifth generation high-tech fleet of fighter-bomber aircraft with the aim to modernize the country's air force which includes the induction of 2 squadrons of Chengdu J-10 aircraft."[11] The J-10 export deal is estimated to cost a total of $1.5 billion USD, with a flyaway price of $41 million USD for each J-10 fighter with maintenance and parts inclusive.[citation needed] It was reported by Jane's Defence Weekly on 2006-01-09 that a more advanced version of the J-10 is planned, referred to as the Super-10, with a more powerful engine, thrust-vector control, stronger airframe and passive phased-array radar.[12] Iran was reported to have signed a deal to purchase 24 J-10s from China in October 2007. The agreement is estimated at a cost of about $1 billion, with deliveries of the 24 jets expected between 2008 and 2010 to replace MiG-29 jets.[13] However China later denied that such a sale had taken place. [14] [edit] Foreign participation This article is in need of attention from an expert on the subject. WikiProject Aviation or the Aviation Portal may be able to help recruit one. (March 2009) Drawing of the canceled Chengdu J-9 Wind tunnel model of the canceled Chengdu J-9 The canceled Israeli IAI Lavi According to official Chinese sources, the J-10 is said to have been developed from the now canceled Chengdu J-9. However, there have been conflicting reports about a possible relationship between the J-10 and the Israeli IAI Lavi fighter program,[7] the latter having a similar canard-configuration. The J-9 program predated both of the other aircraft.[15] In an interview, the general designer of J-10, Mr. Song Wencong (宋文骢) said, "Our nation's new fighter's external design and aerodynamics configuration are completely made by us and did not receive foreign assistance, this made me very proud. Our nation developed J-9 in the 1960s, this adopted the canard configuration. So, those statements that said J-10 is a copy of Israeli Lavi are just laughable."[16] The strongest admission of Israeli involvement in the J-10's development by Israeli authorities appeared in a statement made by an official as American authorities investigated alleged Lavi technology transfers to China. The Director General of Israel's Ministry of Defense David Lari "acknowledged in an Associated Press interview that 'some technology on aircraft' had been sold to China and that some Israeli companies may not have 'clean hands'".[17]. In May 2008, Jane's Information Group reported several interviews with Russian sources claiming to be involved with various Chengdu military projects. A number of engineers, designers and technical specialists described their visits to Chengdu and other areas of China in the 1980s. A source alleged that high-level Chengdu officials described the possession of a single Lavi prototype at one of Chengdu's facilities. They also claim that in 2000, two years after the J-10's maiden flight, aerodynamic models were sent to Russian wind tunnel testing facilities to study the J-10's aerodynamics.[18] During the 2006 Farnborough Airshow, the Russian Siberian Aeronautical Research Institute (SibNIA) confirmed its participation in the J-10 program. According to the article, this participation was limited to observation and instruction as "scientific guides." The sources also claimed that the J-10 was based on the canceled Israeli IAI Lavi.[19] Kommersant's reporter Kostantin Lantratov affirmed that Russian consent was required to export the J-10, given its Russian AL-31 engine. [edit] Design J-10 was designed by the Chengdu Aircraft Design Institute (CADI), a subordinate research institute of Chengdu Aircraft Industry Corporation (CAIC). Some of the designers and their roles are identified as follows; Xue Chishou (薛炽寿, chief engineer, also deputy general manager of CAIC), Zhou Ziquan (周自全, chief test engineer, also deputy director of CADI). In a rather unusual agreement, the single seat version of the J-10 and the twin seat version of J-10 were designed by two different general designers; Song Wencong for the single seat version and Yang Wei (杨伟) for the twin seat version, also the general designer of the JF-17 light-weight fighter. Sang Jianhua (桑建华) of CADI was responsible for the stealth feature designs. [edit] Airframe and cockpit A model of the J-10. Constructed from metal alloys and composite materials for high strength and low weight, the airframe's aerodynamic layout adopts a "tail-less canard delta" wing configuration. A large delta wing is mid-mounted towards the rear of the fuselage, while a pair of canards (or foreplanes) are mounted higher up and towards the front of the fuselage, behind and below the cockpit. This configuration provides very high agility, especially at high speed. A large vertical tail is present on top of the fuselage and small ventral fins underneath the fuselage provide further stability. A rectangular air intake is located underneath the fuselage, providing the air supply to the engine. Also under the fuselage and wings are 11 hardpoints, used for carrying various types of weaponry and drop-tanks containing extra fuel. The retractable undercarriage comprises a steerable pair of nose-wheels underneath the air intake and two main gear wheels towards the rear of the fuselage. The cockpit is covered by a two-piece bubble canopy providing 360 degrees of visual coverage for the pilot. The canopy lifts upwards to permit cockpit entry and exit. The Controls take the form of a conventional centre stick and a throttle stick located to the left of the pilot. These also incorporate "hands on throttle and stick" (HOTAS) controls. A zero-zero ejection seat is provided for the pilot, permitting safe ejection in an emergency even at zero altitude and zero speed. [edit] Avionics (aircraft related) [edit] Flight control system Due to the J-10's aerodynamically unstable design, a digital quadruplex-redundant fly-by-wire flight control system aids the pilot in flying the aircraft. Chinese aircraft designer Yang Wei is claimed to be the chief designer of the fly-by-wire flight control system, although this is disputed by analyst Richard Fisher who credits Israeli consultants for developing the system.[20] The flight control computer provides automatic flight coordination and keeps the aircraft from entering potentially dangerous situations such as unintentional slops or skids. This therefore frees the pilot to concentrate on his intended tasks during the combat. [edit] Flight instrumentation Information is provided visually to the pilot via three liquid crystal multi-function displays (MFD) in the cockpit. Chief designer of the flight instrumentation panel was Zhou Han (周寒, unrelated to the chief test engineer), who was in charge of both the CRT display design at the early stages of development and the later liquid crystal display (LCD) design that is currently adopted by J-10 in service. The LCD display panel entered service shortly after 2000. The LCD displays and earlier CRT displays for J-10 (and that of WZ-10, J-11 and JH-7) are manufactured by the Suzhou Long Wind Machinery Plant (苏州长风机械总厂), later reorganized as AVIC Radar and Avionics Equipment Research Institute (中航雷达与电子设备研究院). In addition to the flight instrumentation, a Chinese holographic head-up display (HUD) is also present. The HUD shows important flight and combat related information such as targeting cues. It can also be used as a radar scope, a feature believed to be inspired by the HUDs of Russian aircraft, that allows the pilot to keep his eyes focused at infinity while working with his radar. Monochrome images from electro-optical avionics pods (FLIR and targeting pods) can also be displayed on the HUD. The HUD was designed to overcome issues with the HUDs of Russian fighters, which experienced significant fogging problems when deployed in humid and tropical zones of China, as they were originally designed for deployment in arid Arctic/sub-Arctic zones. The modular design of the HUD system and use of the MIL-STD-1553B databus architecture allows HUDs of Western origin to be integrated if desired by the user. [edit] Avionics (mission related) [edit] Electronic warfare A comprehensive internal electronic counter-measures (ECM) suite is likely to be present, which can be supplemented by active jammer pods such as the BM/KG300G carried externally on the aircraft's hardpoints. Additionally, the KZ900 signals intelligence (SIGINT) pod can be carried for reconnaissance missions. [edit] Infra-Red Search and Track A Chinese infra-red search and track (IRST) system developed by the Sichuan Changhong Electric Appliance Corporation, the Type Hongguang-I (Rainbow Light-I) Electro-Optical Radar (虹光-Ⅰ型光电雷达), is integrated with the J-10. It is a third generation optronics system utilising a HgCdTe focal array with imaging infra-red (ImIR) capability. Receiving its certification on 3 March 2005 and subsequently entering service with the PLAAF, the system was revealed to the public one year later at a conference on the Sichuan province of China, during which the system was demonstrated to visiting officials. Based on the limited information released, Type Hongguang-I has a maximum range of 75 km. Although the Type Hongguang-I was designed to be lighter and more compact that similar Russian systems so that it could be fitted in the nose of J-10 while leaving enough space for a suitable radar, the current production model J-10 does not have enough space and must carry a podded version externally on one of the aircraft's hardpoints. However, recently released images show a modified variant of the J-10 with what is believed to be an IRST device fitted to the upper starboard side of the nose (see Variants). Type Hongguang-I is also designed to be compatible with China's Shenyang J-11, Shenyang J-8 and Xian JH-7 combat aircraft, as well as the Xian H-6 bomber and Sino-Pakistani JF-17 light-weight fighter. [edit] Radar and targeting According to Chengdu Aircraft Industry Corporation officials the J-10 uses a multi-mode fire-control radar designed in China. The radar has a mechanically scanned planar array antenna and is capable of tracking 10 targets. Of the 10 targets tracked, 2 can be engaged simultaneously with semi-active radar homing missiles or 4 can be engaged with active radar homing missiles.[21] The radar is believed to be designed by the Nanjing Research Institute of Electronic Technology (NRIET), designated KLJ-10 and a smaller variant is claimed to be installed on the JF-17 light-weight fighter.[22] Believed to be based on technologies from Russia, Israel or a combination of both, the radar should be comparable to Western fighter radar designs of the 1990s. It may also be replaced by more advanced radars of other origin on export versions of the J-10. The Italian FIAR (now SELEX Galileo) Grifo 2000/16, has been offered to the Pakistan Air Force for installation on the J-10, should the PAF induct the aircraft.[23] On June 14th, it was announced by Chinese state media that a version of J-10 has been equipped with a phased array radar. [24] In Chinese military technology related exhibitions, various helmet-mounted display (HMD) systems developed by Chinese organisations have been shown. It is believed that the J-10 is integrated with such a system to assist the pilot in targeting enemy aircraft. The J-10 has also been featured in photos and models carrying the FILAT (Forward-looking Infra-red Laser Attack Targeting) pod for laser designation of targets and the Blue Sky forward looking infra-red (FLIR) pod for low visibility, low altitude flights. [edit] Propulsion The J-10 is powered by a single Russian Lyulka-Saturn AL-31FN turbofan engine giving a maximum static power output of 12,500 kgf (123 kN, 27,600 lbf)). The most significant difference between the AL-31FN and the AL-31F is the arrangement of certain parts and mechanisms due to spacial limitations of the engine bay in the J-10. The AL-31F is designed for a twin engine aircraft such as the Su-27. For the J-10's AL-31FN variant, protruding parts of the engine such as the gearbox and pump are mounted opposite to that of AL-31F. The AL-31FN is expected to be replaced by a domestic powerplant developed and manufactured in China, the WS-10A (WoShan-10A) Taihang turbofan, giving a thrust of 129 kN (13,200 kgf or 29,101 lbf). A variant of WS-10A with thrust vector control, reported to have asymmetric nozzles, is also undergoing testing according to reports. [edit] Weaponry and external loads The aircraft's internal armament consists consists of a 23 mm twin-barrel cannon, located underneath the port side of the intake. Other weaponry and equipment is mounted externally on 11 hardpoints, to which around 4,500 kg (9,900 lb) of weaponry such as missiles and bombs, drop-tanks containing fuel and other equipment such as avionics pods can be attached. Air-to-air missiles deployed may include short range air-to-air missiles such as the PL-8 and PL-9, medium-range radar-guided air-to-air missiles such as the PL-11 and PL-12, unguided and precision guided munitions such as laser-guided bombs, anti-ship missiles such as the YJ-9K) and anti-radiation missiles such as the PJ-9. [edit] Variants * J-10A: Single seat multi-role variant. The export designation is F-10A.[25] * J-10S: Twin-seat fighter-trainer variant of J-10A. The forward fuselage of the aircraft is stretched to accommodate an additional pilot seat, two pilots sit in tandem with a single large bubble canopy. Also incorporates an enlarged dorsal spine which may accommodate additional avionics equipment or fuel. As well as serving as training aircraft, the J-10S may also be used for the ground attack role where the rear seat pilot would act as the weapon systems operator.[26] * J-10B: An upgraded variant of J-10. Existence is not confirmed by official Chinese sources but numerous images, believed to be authentic, of a new J-10 variant have appeared. They show the prototype of a J-10 modified with a divertor-less supersonic intake (DSI), an infra-red search and track (IRST) sensor, modified (extended) vertical stabiliser and ventral fins, new under-wing hardpoints and a modified nose that could indicate a new type of radar. [27][28] Could be the same aircraft as "Super-10", a variant reported by Russian sources in January 2006 to be under development and incorporating a passive phased array (PESA) radar, stronger airframe and the Saturn AL-31FN M1 turbofan engine with 3D thrust vector control (TVC).[29] * FC-20: An export variant of J-10 designed for the Pakistan Air Force.[30] First flight stated to take place in 2009.[31] [edit] Operators People's Republic of China * People's Liberation Army Air Force - Over 120-160 in service; it is rumoured that a total of 300 may be produced.
