The invention provides a helicopter air inlet channel anti-icing system using lubricating oil as a heat source. The helicopter air inlet channel anti-icing system comprises an active heat pipe, a lubricating oil heat exchanger, a heat pipe heat exchanger, a liquid pump, a liquid pipeline, an anti-freezing solution and the like. Hot lubricating oil in a main reducer of the helicopter is used as a heat source to heat the skin of the air inlet channel and prevent the surface from being frozen, waste heat on the helicopter is recycled by the system, hot air does not need to be led from an engine, the influence on the power of the engine can be effectively reduced, and the overall flight performance of the helicopter is improved.
本发明提供一种利用滑油作为热源的直升机进气道防冰系统,所述直升机进气道防冰系统包括:有源热管、滑油换热器、热管换热器、液泵、液体管路、防冻液、等部件。使用直升机主减中的热滑油作为热源,对进气道蒙皮进行加温,防止表面结冰,本系统对直升机上的废热进行回收利用,不需要从发动机引热空气,可以有效减少对发动机功率的影响,提高直升机整体的飞行性能。
