民用航空发动机进气道防冰功率的计算方法研究

摘要

根据民用航空发动机短舱防冰系统设计的要求,对进气道的防冰功率进行了的计算研究.基本思路是利用结冰数值计算软件计算进气道水滴撞击范围,在此基础上,根据进气道防冰表面不同温度的要求,确定了进气道防冰系统引气功率的需求.提出的发动机进气道防冰功率计算方法,可供民用航空发动机短舱进气道防冰系统设计参考和借鉴.%This paper investigate bleeding air requirement definition method of the civil aero-engine inlet anti-icing system.Based on the dry evaporation and wet evaporation temperature requirements of the sur-face ,simulation was made by IRC software to calculate the impingent limit and use the heat balance mod-el to calculate the hot air bleeding power requirements ,which provide a reference method to the aero-en-gine inlet anti-icing bleeding power requirement definition.
