A large aspect ratio unmanned fixed-wing aircraft

Abstract

An unmanned fixed-wing aircraft with a large aspect ratio provided by the present invention includes an aircraft, the aircraft includes a fuselage, wings and a tail, the wings include a main wing, and auxiliary wings are arranged at both ends of the main wing. The tail includes elevator, rudder, horizontal tail and vertical tail. The structure is simple and the design is reasonable. It increases the strength and stiffness of the wing without significantly increasing the weight of the wing. Higher, the overall force is more uniform, not easy to break, easy to install and dismantle, easy to operate, easy to carry for maintenance, improve the overall service life, and have wider applicability.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to an unmanned fixed-wing aircraft with a large aspect ratio. Background technique [0002] Aircraft is an instrumental flying object manufactured by humans, capable of flying off the ground, flying in space and controlled by humans in the atmosphere or in space outside the atmosphere. Those flying in the atmosphere are called aircraft, and those flying in space are called spacecraft. Airplanes with larger aspect ratios have better performance in keeping air in the air. Most of the skin-skeleton fixed-wing unmanned aerial vehicles have a beam structure, and the rear edge of the wing rib is easy to break, resulting in a decrease in flight performance or even damage to the aircraft. The design without ribs reduces the stiffness of the wing and is easy to torsion deformation. Large aspect ratio fixed-wing unmanned aerial vehicles are mostly standard airfoils, and their performance v...

Problems solved by technology

[0003] The problem to be solved by the present invention is to provide a large-aspect-ratio unmanned fixed-wing aircraft to solve the problem of large-aspect-ratio aircraft with better performance in the space. The trailing edge is easy to break, resulting in reduced flight performance or even damage to the aircraft. The design without ribs reduces the stiffness of the wing and is easy to twist and deform. Most fixed-wing unmanned aerial vehicles with large aspect ratios are standard airfoils, which have various performances in actual situations. There are differences. The multi-section wings are mostly rigidly connected, such as bolts, etc., which is inconvenient to disassemble.
