摘　　要：为计算吸气式空气涡轮冲压(air-turbo-ramjet,ATR)发动机过渡态性能,建立了ATR发动机过渡态模型.通过与传统涡喷发动机供油原则对比得到了ATR发动机供油应遵循的规律,计算得到了给定供油规律下的ATR发动机加减速性能.结果显示ATR发动机在供油规律选择上更加灵活,并能很好地满足喘振裕度的要求.根据ATR发动机自身特点,在补足低转速特性后,本模型可直接模拟ATR发动机起动过程.In order to simulate the transition state performance of air-turbo-ramjet（ATR）engine,an ATR engine model was established.The ATR engine fuel feeding law and the acceleration/deceleration performance were obtained through comparing to the traditional turbojet fuel feeding principle.The result shows that the ATR engine is more flexible in the selection of fuel feeding law and would satisfy the requirement of surge margin better.The engine start process could be simulated by this model after adding low speed of rotation characteristic according to the charateristic of ATR engine.
