Abstract

The invention provides a method for designing a UAV (unmanned aerial vehicle) provided with a deflectable winglet. The problems that most UAVs nowadays have big height loss when performing dive and climb maneuvers, cannot guarantee cruising property and has poor stalling characteristics are solved by respective design of a main wing, inverted V empennages and the deflectable winglet of the UAV. The inverted V empennage layout and a rear propeller power mode are adopted. According to the layout, interference drag between the empennages as well as between the empennages and the fuselage can be reduced with fewer parts, and downwash of the empennages can be weakened to enhance course stability. Meanwhile, propeller slipstream can be avoided by the layout, so that pitching stability is improved.

Description

technical field [0001] The invention belongs to the design field of unmanned aerial vehicles, and in particular relates to a design method for an unmanned aerial vehicle with deflectable winglets. Background technique [0002] In the development of modern military power, people pay more and more attention to informatization and automation, and the increasingly complex battlefield environment also requires the improvement of the comprehensive combat capability of the troops. With the rapid development of artificial intelligence, sensor technology, and automatic control technology, more and more attention has been paid to the multi-task performance and combat capabilities of UAVs. Although the number, types, and frequency of UAVs are rapidly increasing, multifunctional and highly mobile military UAVs have not yet been deeply researched and developed. In terms of civilian use, it can be loaded with infrared, digital cameras or weather sensors and other equipment. The aircraft ...
