The invention provides a test method of a helicopter air inlet channel anti-icing system. The helicopter air inlet channel anti-icing system comprises an air inlet channel and a heating assembly. The method comprises the steps that a normal temperature test is conducted on the helicopter air inlet channel anti-icing system, and when the temperature characteristic of an air inlet channel does not meet the anti-icing design requirement, iterative correction is conducted on the air inlet channel till the air inlet channel meets the anti-icing design requirement; an icing wind tunnel test is carried out on the helicopter air inlet channel anti-icing system, and when the heating performance of the heating assembly does not meet the design requirement, iterative correction is carried out on the heating assembly till the design requirement is met; and carrying out a spraying tower test on the helicopter air inlet channel anti-icing system, and verifying the anti-icing performance of the helicopter air inlet channel anti-icing system. Test items of different development stages are reasonably planned, the system performance can be fully verified, the repair workload after installation is reduced, and the development time and the test cost can be saved.

    本发明提供一种直升机进气道防冰系统的试验方法,所述直升机进气道防冰系统包括:进气道和加热组件;所述方法包括:对直升机进气道防冰系统进行常温试验,进气道的温度特性不符合防冰设计需求时,对进气道进行迭代修正直至符合防冰设计需求;对直升机进气道防冰系统进行冰风洞试验,在加热组件的加热性能不符合设计需求时,对加热组件进行迭代修正直至符合设计需求;对直升机进气道防冰系统进行喷洒塔试验,验证直升机进气道防冰系统的防冰性能。对不同研制阶段的试验项目进行了合理规划,既能对系统性能进行充分验证,减少装机后的返修工作量,又能节省研制时间和试验费用。
