摘　　要：冲压空气涡轮系统(RamAirTurbine,简称RAT系统)是飞机上的备份电源系统。当飞行中出现主电源无法正常供电的情况时,该系统作为应急电源为飞机上的重要设备供电。对冲压空气涡轮系统装机后的最低使用空速的测试方法进行了研究,并进行了试验验证。阐述了试飞方法、试飞改装方案,并举例说明了试验的过程。通过实例对该方法的可行性进行了验证,证明该测试方法具有可行性并可以保证飞机安全。The Ram Air Turbine system is the backup power system of aircraft. And it severs as the emergency power system which provides electrical power to the critical loads when a total loss of normal AC power occurs during flight. This paper studies the test method for the lowest allowable airspeed of Ram Air Turbine system after assembly and uses a flight test to verify the method. And it states the flight test method, flight test modification and process of an example of flight test. Using the example, it proves the feasibility of the test method and it also proves that this method can ensure the safety of aircraft.
