A composite rotating fixed-wing aircraft and its design method

Abstract

The composite rotating fixed-wing aircraft consists of the coaxial counter-paddle, reverse gear, engine output shaft, engine with a starter-generator, wings, tail blades, landing device, culvert, steering gear, fairing, fuselage, motor, motor drive shaft, wing control unit of small angle of attack, aileron rudder surface, and tailplane rudder surface. Co-axial counter-blade is located in the upper part of the aircraft, which connects with the engine output shaft; the reverse gear is installed between the co-axial counter-propellers; the motor connects with motor drive shaft powered by the starter-generator of the engine; the wings are located on both sides of aircraft and connect with the fuselage; the tail blades are located at the aircraft tail, which are installed behinde motor drive shaft; the landing device is located under the lower part of the fuselage and fixed with it; the culvert connects with the landing device; the fairing is installed in the culvert and connects with the steering gear; the wing control unit of small angle of attack is installed on the wing. The aircraft design method has six steps with strict scientific idea; this invention has a wide range of practical value and application prospect.

Description

(1) Technical field [0001] The invention relates to an aircraft and a design method thereof, in particular to a rotary-fixed-wing composite aircraft and a design method thereof, and belongs to the field of aerospace technology. (2) Background technology [0002] 1. Foreign research background [0003] Draper Small Autonomous Aerial Vehicle (or DSAAV) researched by MIT. The fuselage length is 1514 mm, and the rotor diameter is 1455 mm. Draper is controlled by radio remote control. The equipment on Draper mainly includes: differential GPS, six-degree-of-freedom inertial measurement unit, two-axis magnetic compass, ultrasonic altitude sonar and other sensors, system At the same time, the Kalman filter is used to improve the accuracy of navigation, and improve the reliability and fault tolerance of the system.

Problems solved by technology

[0018] Summarizing the various unmanned aerial vehicles introduced above, it can be seen that the common problems of unmanned helicopters are slow forward flight speed, small payload, short cruising range, and insufficient wind resistance.

This limits the maneuverability of the tracked trajectory
