旋翼固定翼可切换飞行器概念研究

Research on a conceptual aircraft design with switch configuration between rotor and fixed-wing

结合旋翼和固定翼的飞行特点,提出了一种可以在垂直起降和水平飞行之间切换状态的飞行器布局。围绕该类飞行器的力学特性、气动特性作出了分析和计算,并根据分析和计算的结果,制作并试飞了实物模型。根据研究结果做出的实物样机试飞参数与理论结果符合较好,初步达到了设计目的,证实了这种飞行器布局具有一定的可行性和应用前景。

According to the characteristics of the rotorcraft and the fixed - wing aircraft, it proposes a configura- tion of fixed - wing aircraft, which is capable of short - takeoff and vertical - landing. In this design, airfoils on both sides rotate respectively around the pitch axis to switch the flying mode, so as to achieve the purpose of VTOL or the cruising flight. The paper analyzes the mechanical characteristics, aerodynamic characteristics and body structure of the aircraft, provides a basis for the production of the model. Taking the test for the physical prototype, it shows that the theoretical results match with the test data, the aircraft configuration has certain fea- sibility and certain prospects for application.
