摘　　要：为确保飞机已设计成为飞行中突遇风切变等恶劣天气影响仍能够正常工作,不会出现故障对飞行安全产生影响,各国民用飞机适航规章中均对动力装置系统的负加速性能进行了规定,要求以试飞的形式进行表明条款符合性的验证工作。本文对我国首次进行的某型民用飞机动力装置系统负加速度飞行试验和试验数据进行分析,飞机按要求连续3次进入负加速状态,飞机和发动机工作正常,未出现任何故障,试验成功,表明抛物线试飞方法准确可靠,该型民用飞机动力装置系统符合适航规章要求。In order to ensure the civil aircraft has been designed to operate normally when the aircraft encounter had weather in flight task,such as wind shear,and no failures emerge to impact on flight safety,the regulations for civil aircraft of all nations regulate requirements on negative acceleration performance of civil aircraft powerplant system.It requires that the civil aircraft powerplant system to be certificated through flight test. This paper analyzes the^civil aircraft powerplant system negative acceleration flight test method and test measured parameters.The aircraft entered into negative acceleration condition for 3 successive times according to requirements during flight test.The aircraft and engines operate normally without any failure.The flight test indicated that the parabola flight method for negative acceleration is successful and the civil aircraft powerplant system can comply with the airworthiness requirement.
