Abstract

The present invention is a design method for a UAV with deflectable winglets, which solves the problem of most UAVs doing dives by designing the UAV main wing, inverted V tail and deflectable winglets respectively. There is a large altitude loss during climbing and climbing maneuvers, the endurance cannot be guaranteed, and there is a problem that the stall characteristic is not good. It adopts inverted V-shaped tail layout and rear propeller power mode. This layout can not only reduce the interference resistance between the empennages and between the empennage and the fuselage with less total number of components, but also weaken the airflow downwash on the empennage to enhance the directional stability. At the same time, this layout can also avoid propeller slipstream and improve pitching stability.

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 ...
