Title
(EN) Cylinder type launch folding wing unmanned aerial vehicle and launch method thereof
(ZH) 筒式发射的折叠翼无人机及其发射方法
Abstract
(EN)
The invention provides a cylinder type launch folding wing unmanned aerial vehicle and an launch method thereof. The cylinder type launch folding wing unmanned aerial vehicle comprises a folding wingunmanned aerial vehicle (7) and a launch cylinder (6), wherein the folding wing unmanned aerial vehicle (7) is in a complete folding state and is arranged in the launch cylinder (6); when the launch cylinder (6) launches the folding wing unmanned aerial vehicle (7), the folding wing unmanned aerial vehicle (7) is ejected out of the launch cylinder (6), and climbs up to enter a complete unfolding loitering task state after a gradually unfolding varying process. The cylinder type launch folding wing unmanned aerial vehicle has the characteristics of simple structure, light weight and high engineering feasibility. Meanwhile, a Z-shaped folding elastic wing with the advantages of small land occupation in a folding state, big wing area in an unfolding state, large aspect ratio and the like is used to effectively improve the space use ratio and the aerodynamic performance of the cylinder type launch folding wing unmanned aerial vehicle in the loitering task state.
