陆空两用飞行汽车升力系统设计与分析

摘要

设计一款采用涵道风扇作为飞行动力元件的陆空两用飞行汽车，根据主要性能指标及布置形式，基于空气动力学动量理论对涵道风扇升力进行设计计算。通过与发动机的匹配计算得出陆空两用飞行汽车的飞行性能参数，最终提出一种涵道风扇式飞行汽车的设计方案，验证了采用涵道风扇形式的轻型陆空两用飞行汽车设计的可行性。%The air-ground vehicle which can run on ground and fly in air is adopted the ducted fun as the flight power supply. In this paper, the lift system is designed based on the aerodynamics and vehicle performance index.The flight performance pa-rameter is obtained through matching computation with engine.The general planning of air-ground vehicle is presented.Final-ly, the feasibility of air-ground vehicle is proved.
