Design And Realization Of Small VTOL Two-Axis Aircraft

Small-scale unmanned aerial vehicles have been widely concerned in recent years. The new two-axis vertical takeoff and landing aircraft studied in this paper has low cost, small volume and low requirements for landing space, and is suitable for the application of mission in the complex environment The Firstly, the present situation of the development of small unmanned aerial vehicles at home and abroad is analyzed,and the popular research directions are analyzed in detail. The advantages and disadvantages of the small unmanned aerial vehicles with different structures are comprehensively understood. Then, The two-axis tilting rotor vertical take-off and landing aircraft, and analyzed the mechanical structure of the two aircraft,respectively, on the two different mechanical structure of the new two-axis aircraft The direction of the movement of the left and right sides of the servo tilting system and the thrust variation of the two sides of the power system are analyzed in different motion states and different postures. Based on the mechanical structure of the double -channel tilting vehicle and the two - axis tilting rotor vertical takeoff and landing aircraft, the mathematical model of the double - channel tilting vehicle and the two -axis tilting rotor vertical take - off and landing aircraft is established, and their differences are analyzed. The flight performance of the double-channel tilting vehicle and the two-axis tilting rotor vertical take-off and landing aircraft is analyzed by MATLAB simulation. The STM32F407 is used as the main control, the electronic gyroscope Instrument, electronic accelerometer, electronic compass as the flight controller IMU unit, using ultrasonic, barometer, GPS module as a height and position measurement unit, designed the flight control system hardware system. Finally, the dual-channel tilting vehicle and the two-axis tilting rotor vertical takeoff and landing aircraft prototype are developed by 3D printing technology. The flight control test of two prototype is used to analyze the design of the double-channel tilting vehicle and the two-axis tilting The advantages and disadvantages of different structures are compared and analyzed. This paper summarizes the problems and solutions in the design process of the design of double-channel tilting and two-axis tilting rotor vertical takeoff and landing aircraft.
