基于力线平移原理的涵道风扇水平推力测试系统

The Ducted Fan Horizontal Pushing Test System Based on Force Line Translation Principle

涵道风扇可作为动力源进行飞行器设计,它是一种高效、安全的动力推进装置。为了在起飞前对飞行器进行推力测试和研究,利用力线平移原理设计了一套涵道风扇水平推力测试系统;经过受力分析和几何误差分析,得到了影响几何误差的主要因素;搭建了测试平台,得到了风扇的推力数据,与厂家给定的初始数据相符。

The ducted fan can be used as a power source for aircraft design,which is an efficient and safe power pushing device.In order to test and study the aircraft s pushing before take-off,a ducted fan horizontal pushing test system has been designed by using the principle of force line translation principle.After force analysis and geometric error analysis,the main factors affecting geometric error are obtained.A test platform has been built,and the pushing data of the fan is obtained,which match the initial data given by the manufacturer.
