The Chengdu J-7 (Chinese: 歼-7; third generation export version F-7; NATO reporting name: Fishcan[1]) is a Chinese fighter aircraft. It is a license-built version of the Soviet Mikoyan-Gurevich MiG-21, and thus shares many similarities with that aircraft. [2] .

The J-7D (Chinese: 歼-7D型歼击机, AKA J-7IIIA 歼-7IIIA; unified NATO codename: Fishcan) was an upgrade of the previous J-7C (J-7III), which was based on Egyptian MiG-21MFs with domestic avionics and HUD.

殲-7，是 中華人民共和國 獲得 苏联 技轉生產的 米格-21戰鬥機，该机型北约代号与其原型机相同，为“鱼床（Fishbed）”。 歼-7采取 三角翼，单座单发，机头进气的设计，殲7技轉期間因 中蘇交惡 終止蘇聯技術支援，中共航空工業後解析消化其技術，達成飛機全國產化，並持續改良。 1965年9月由中国 沈阳飞机制造厂 制造第一架歼7的組装，1966年12月28日正式定型並量产，后来将生产线转移至成都飞机制造厂和贵州飞机制造厂，并于2013年停产 [1]。 前后共生产了 …

The new jet, developed in 1988, featured a new JL-7A radar capable of launching the latest PL-8 missiles, reverse-engineered Marconi Type 956 HUD, as well as Type 930-4 countermeasure system. J-7IIIA (now called J-7D) took its first flight in mid-1991 and joined the PLAAF in 1995.

J-7 drone: Retired J-7s were converted into aerial target drones. Subsequently, the same conversion was also carried out for later variants after their retirement. Some of these drones were destroyed by the Chengdu J-10 during weapons trials. [11] A J-7I seen from above. Note the delta wing and distinctive PLAAF markings.

歼-7D是我国在从埃及购买的 米格-21MF 基础上换装增大推力的涡喷-13F1型发动机、由 HK-03D 瞄准具换成抬头显示器、加装 JL-7A 型火控雷达，组合式电子反制系统，新型箔条/热焰弹投放器等的飞机。 由于 歼-8II 研制进展缓慢和且我国需要更先进的截击机来对抗潜在的苏联威胁，我空军有计划用歼-7D取代歼-8II。 虽然歼-7D的发展是十分成功并且在某些方面显示出改进的性能，但不久歼-8II的成功和引入苏-27SK及其生产线限制了空军对歼-7D的需求。 看看歼-7D，除了默认的 …

Gsh-23L是原苏联1965年根据“加斯特”法则研制而成的23毫米双管机炮,原理为一个炮管发射炮弹时，其后座力通过一个杠杆装置来带动另一个炮管装填及发射炮弹，如此循环往复的发射炮弹。 如此设计的好处在于：结构简单紧凑，高可靠性，并有非常高的射速（甚至远远超过了一些结构复杂的重型转管航炮），射速大约为3000发/分，且该炮全重仅为51公斤。 米格-21MF的RP-21A雷达. 米格-21MF的雷达设备舱. 米格-21MF新型的侧开式座舱盖，舱盖玻璃上是后视镜。 从座舱外来 …

歼-7（中国代号：J-7，英文：Chengdu J-7/F-7 fighter aircraft [1]，北约代号：Fishbed，译文：鱼窝）战斗机，是20世纪60年代中国沈阳飞机制造厂研制的一型单座单发超音速喷气式战斗机。 歼-7是仿制的苏联 米格-21 Ф-13型。 该机后转产至成都飞机制造厂和贵州飞机制造厂，进行后续改进改型、批量生产 [1]。 歼-7战机是中国首款两倍音速歼击机，共有两万多个零部件，新工艺、新技术和新材料达到两百多项之多，是新中国自歼-6以来最复杂的航空系统工程，标志着中国在当 …

2020年7月17日 · J-7 is a single-engine, lightweight fighter aircraft designed and manufactured by Chengdu Aircraft Corporation (CAC) of China. Its design is based on its predecessor, the MiG-21 aircraft. The export version of J-7 has been designated the F-7.

2022年9月14日 · Initial production batch models were known simply as J-7 (export models were the F-7) and appeared from Shengyang in 1966 through a 12-strong commitment. These versions fielded only one 30mm NR-30 cannon and two underwing hardpoints allowed for air-to-air ordnance to be fitted as normal.
