Overall Design, Key Technologies, and Performance Validation of a Dual-Power
Fixed-Wing UAV Based on CUADC Competition Rules
Unmanned aerial vehicle (UAV) technology has shown great potential in the field of payload delivery due to its unique advantages. The twin-engine fixed-wing ground strike UAV combines the power redundancy advantages of twin engines with the efficient flight characteristics of the fixed-wing layout, and has the advantages of high reliability, strong load capacity and long range, and has broad application prospects in both military and civilian fields. This paper focuses on the physical research of twin-engine fixed-wing UAVs. Firstly, this paper analyzes the research status of this field at home and abroad, and points out that foreign countries started earlier and the technology is relatively mature, and although China has developed rapidly, there is still a certain gap between China and foreign countries. Then, the research content is elaborated, including the analysis of the overall design of the UAV, and the influence of aerodynamic layout, structural design and weight distribution on flight performance and optimization methods are explored. In-depth study of the powertrain, involving the selection, matching and installation technology of the twin engines, and how to improve the performance by optimizing the powertrain; Discuss the principles and algorithms of flight control to achieve high-precision flight control and autonomous navigation. Analyze the task load system, study the load integration, material delivery technology and system coordination mode; Finally, the flight test and performance evaluation of the actual prototype were carried out to verify the rationality of the design and put forward improvement measures. Through this study, the aim is to provide comprehensive technical support for the research and development and application of domestic twin-engine fixed-wing UAVs, and to promote the development of UAV technology in China.
