结冰对直升机进气系统压力损失影响的试验研究及分析

Analysis and Research on Icing Test for Pressure Loss of Air Intake System of Helicopter

介绍了直升机发动机进气系统冰风洞摸拟结冰试验情况,对直升机发动机进气系统冰风洞模拟结冰试验结果和进气系统压力损失进行了分析。结冰试验结果表明,随着飞行速度的增加,进气系统结冰时进气压力损失有较大的增加。

This paper introduced the icing test for engine air intake system of helicopter in icing win tunnel,analyzed icing test and air intake pressure loss for engine air intake system of helicopter in icing win tunnel.The icing test results showed that air intake pressure loss to become larger in the flight speed increase on the air intake system icing.This paper provided a reference for anti-icing design of engine air intake system of helicopter.
