摘要
针对某直升机滑油冷却用斜流风机,提出了一套变工况性能的理论计算方法,同时对风机损失计算模型进行了修正,为直升机滑油冷却系统的高空工作性能预测提供了一种可靠的方法。
An academic calculation method of off-design performance is developed for an mixed-flow fan for lubricating system of helicopter,including the correction of the loss calculating model of fan.It supplies a reliable method for estimating the altitude performacne of lubricating system of helicopter.
