摘要

通过发动机螺旋桨功率特性分析

对巡航状况下增压发动机涡轮废气调节阀的调节规律进行了研究

并且预测飞机的经济运行状态.对飞机在4000m海拔高度以恒定速度180km/h巡航工况进行了研究

调节涡轮废气放气阀开度控制空气盒的目标压力

桨距角的变化随螺旋桨特性曲线进行调节.运行的结果显示

通过变桨距调节和涡轮废气阀调节的共同作用

可实现与增压器匹配的压气机运行在68%~76%的高效率区域.

Abstract

The regulation of turbocharger exhaust valve was studied in cruising condition by analysis of engine propeller's power characteristic.The economy of aircraft operation was also predicted.Cruising condition of constant 180km/s was researched at 4000 meters altitude

the target pressure of air box could be reached by adjusting exhaust valve

and the propeller pitch was determined by propeller characteristic map.The results show that compressor matched with turbocharger is working within 68%~76% high efficiency area by regulating propeller pitch and turbocharger exhaust valve at constant speed of the airplane.
