摘要
世界各国在研制无人作战飞机过程中,均将缩比验证机试飞研究作为重要的一环,选择合适的动力系统是该环节中的首要工作。本文阐述了无人机缩比验证机动力装置的选型方法,结合对喷气发动机和电动涵道发动机各自特点的详细分析和试验数据,通过理论推导和汇总经验参数,获得了一套适用于缩比验证机的动力系统质量估算方法。
The selection of proper engine system is the initial work in the research of sub-scaled model flight-test,which is considered an important issue in many countries＇ process of developing an UCAV.This article describes the methods in selecting the engine system for a sub-scaled model,and works out an applicable method to estimate the weight of sub-scaled model engine system by theory deduce and experiential coefficient collection.
