Abstract

The invention discloses a detachable cargo hold connecting wing double-fuselage logistics unmanned aerial vehicle. The detachable cargo hold connecting wing double-fuselage logistics unmanned aerial vehicle comprises a wing body fusion type double-fuselage, a lower main wing, an upper auxiliary wing, a propelling device, a modular detachable cargo hold, a flight control system and a vertical tailwing; curved surface smooth transition is adopted between the wing body fusion type double-fuselage and the lower main wing; the lower main wing and the upper auxiliary wing form a connecting wing structure; the modular detachable cargo hold is located in the middle of the lower main wing; and the flight control system comprises a flap located on the inner side of the lower main wing, an auxiliarywing located on the outer side, an elevator located on the upper auxiliary wing and a rudder. The double-fuselage logistics unmanned aerial vehicle disclosed by the invention has the advantages of relatively high loading space, excellent aerodynamic performance, better airport adaptability, excellent economy and relatively high cargo loading efficiency.

Description

technical field [0001] The invention relates to the field of design and manufacture of unmanned aerial vehicles, in particular to a detachable cargo hold connecting wing double-fuselage logistics unmanned aerial vehicle. Background technique [0002] With the rapid development of e-commerce and the regional economy of airports, the logistics industry has become more and more aware of the importance of drones, and has formed a long-distance, medium-distance, medium-distance, short-distance, and terminal logistics system. The terminal and short-distance logistics distribution is generally It can be realized by manned truck express delivery or multi-rotor UAV. Long-distance can be completed by enterprise railway, highway and large-scale passenger-to-cargo manned aircraft. However, for medium-distance and medium-distance logistics transportation, the use of the above methods will increase the cost and urgently need a solution. An air transportation method used for medium-distanc...
