摘　　要：负加速度试飞是民用飞机适航取证试验的重要组成部分,民机负加速度试飞在国内尚属首次,具有对机组操纵技术要求高、风险难度大的特点。本文结合已经完成的燃油系统负加速度试飞,对负加速度时飞机的飞行状态,动作要领进行了总结。另外,对负加速度飞行时动力装置的燃油系统的工作情况进行了分析。Negative ＂g＂ flight test is a very important part in airworthiness certification flight test for civil airplane. It is the first time to do this type of experimentation in domestic aviation field. The test is highly risky and needs well - skilled flight crew. Based on a fuel system certification test, the fight state of the aircraft and the essential operations under negative ＂g＂ flight are studied. Moreover, the work condition of the fuel system at such flight condition is analyzed.
