Performance test of airborne windmilling start for a turbofan engine
摘要
Abstract
In order to improve the control law of airborne windmilling start for turbofan engines and enhance windmilling start performance and reliability,a specific aviation turbofan engine that utilized a fuel-air ratio control mode for windmilling start was selected as the research object.Based on the results of windmilling start tests conducted on an altitude test facility,the effects of ambient temperature,cold and hot starts,flight altitude,and flight speed on windmilling start performance were analyzed.The results show that a decrease in flight speed has the most significant impact on the increase in starting time,extending it by 89%.An increase in flight altitude has a secondary effect,extending the starting time by 21%.The effects of cold weather and cold starts are relatively small.According to the test results,the correction coefficients of starting fuel-air ratio related to atmospheric pressure,Mach number,and temperature were designed.Therefore,when altitude increases,flight speed decreases,ambient temperature drops,or during cold starts,the fuel-air ratio for windmilling start is increased to shorten the starting time.关键词
