1998年6月8日下午,由成都飞机公司等9家单位合作研制改进的歼7FS试验机,在空军第三试飞大队大队长钱学林的驾驶下,以发动机最大状态起飞,经过22分钟飞行后正常着陆.飞机和发动机各系统及仪表工作正常,成功地实现了首飞.这标志着我国在军机改进改型研制上又迈出了一大步.歼7FS是在一架歼7Ⅱ型科研训练机的基础上,更换新的带下颌进气道的机身前段,并配装高推力的新发动机,加装雷达冷却系统和交流电系统,加装视频记录系统、飞行参数记录系统、武器管理系统和GPS.成飞公司充分发挥高科技CIMS技术应用优势,从无纸设计到无纸
On the afternoon of June 8, 1998, an improved J-7FS testing machine was jointly developed by nine units such as Chengdu Aircraft Company under the control of Qian Xuelin, the third test pilot of the Air Force, taking the engine at its maximum state and flying for 22 minutes After normal landing, the aircraft and engine systems and instruments work properly, the successful implementation of the first flight.This indicates that our country in the improvement of military aircraft development has taken another big step.J-7FS is a J-7II type of scientific research On the basis of the training machine, replace the new front fuselage with jaw inlet and equipped with a new engine with high thrust, install radar cooling system and AC system, install video recording system, flight parameter recording system, weapons management System and GPS. Into the company to take full advantage of high-tech CIMS technology applications, from paperless design to paperless
