摘要
本文对两型直升机动力装置冷却通风系统构型进行了介绍,选取不同状态下的试验数据计算了短舱内不同截面上的冷却比,得出了两型直升机动力装置冷却通风系统地面特性。通过对比可知,B型机的冷却通风系统设计更为合理,其可为今后直升机冷却通风系统的设计提供借鉴。
In this paper, the two type of helicopter power plant cooling system configuration were introduced, test data of different state was corrected to calculate the cooling ratio of cooling flow in the different section of engine cabin. And power plant cooling system of two type of the helicopter ground characteristic was acquired. By contrast, the design of type B helicopter cooling ventilation system was more reasonable, and it can provide reference for the design of helicopter cooling ventilation system in the future.
