The ChangKong-1 is a radio-controlled , jet-powered subsonic unmanned aerial vehicle developed from the Soviet Lavochkin La-17C. Developed by Nanjing Institute of Aeronautics in the late 1960s, the ChangKong-1 has been in serving with the PLAAF since the late 1970s for target drone and nuclear air sampling roles.
长空（ChangKong）-1是一种无线电-控制、喷气动力亚音速无人机基于苏联Lavochkin La-17C型发展。在1960年后期由南京航空学院发展，长空-1型从1970年后期以后在PLAAF服役用于靶机和核空气取样任务。
The PRC obtained a small number of the Lavochkin La-17 radio-controlled, ramjet-powered target drone from the Soviet union in the late 1950s. These drones were being sued for airborne- and air-defence weapon testing and practicing. Acquisition of additional units was unsuccessful due to Moscow’s decision in 1960 to stop all of its technical aids to the PRC. This forced the PLA to develop its own indigenous target drone ChangKong-1.
在1950年后期中国从苏联获得了少量Lavochkin La-17型无线电-控制，喷气动力靶机。这些无人机用于机载-和防空武器测试和练习。另外的单位在1960年由于莫斯科决定停止对中国所有它的技术帮助而无法获得。这迫使PLA发展本国的靶机长空-1型。
The ChangKong-1 project began in the early 1960s, with the development work carried out by the PLAAF Weapon Test & Training Base. The chief designer of the programme is General Zhao Xu, who is known as ‘the Father of Chinese uav’. Several La-17C examples were dissembled by Chinese engineers for study and reverse engineering. Because of the PRC’s incapability to produce a suitable ramjet engine, the indigenous target drone was powered by a Wopen-6 (WP-6) turbojet engine originally developed for the Shenyang J-6 (MiG-19 Farmer) fighter.
长空-1型计划在1960年早期开始，由PLAAF武器测试和训练基地进行发展工作。计划的设计总负责人是中国工程院院士赵煦将军，也被誉为‘中国无人机之父’。一些La-17C型样机是为研究和反向工程被中国工程师掩饰。因为中国没有能力生产一种合适的冲压式喷气发动机，国产靶机动力由一台涡喷-6（WP-6）涡喷发动机提供，最初用于沈飞J-6（米格-19“农夫”）战斗机。
The ChangKong-1 successfully flew in December 1966, but the development programme was severely disrupted by the political impact of the ‘Culture Revolution’ in the 1960s~70s. The ChangKong-1 development was resumed by Nanjing Institute of Aeronautics (now Nanjing University of Aeronautics & Astronautics, NUAA) in the 1970s and the development did not finish until 1976, eight years after the project began. The ChangKong-1 entered PLAAF service in the late 1970s for weapon testing and air defence training.
长空-1成功地在1966年12月飞行，但是发展计划由于某些原因在1960年~70年受到干扰。在1970年长空-1发展被南京航空学院重新开始（现在南京航空航天大学，NUAA）和发展直到1976年前没有完成，这已经在计划开始8年之后。在1970年后期长空-1型用于武器测试和防空训练进入PLAAF服役。
