Hovering type folding wing lifting body aircraft based on variable centroid technology

Abstract

The invention relates to an aviation aircraft, and in particular relates to a hovering type folding wing lifting body aircraft based on a variable centroid technology. According to the technical scheme, the hovering type folding wing lifting body aircraft based on the variable centroid technology comprises a lifting body airframe (1), a variable centroid mechanism (2), a vectored thrust mechanism (3) and a wing rotation folding mechanism (4), wherein two front wings (41) and two rear wings (42) which are connected with the lifting body airframe (1) are in a wing combination type serial wing layout. By adopting the hovering type folding wing lifting body aircraft based on the variable centroid technology, the problems of take-off and landing performances and multi-attitude flight performance of a fixed wing aircraft are solved, and the functions of vertical/short-distance take-off and landing, thrust vectoring and small-space flight of the fixed wing aircraft are realized.

Description

technical field [0001] The invention relates to an aviation aircraft, in particular to a hoverable lifting body aircraft. Background technique [0002] At present, in the field of aviation in the world, aircraft are mainly divided into two types: fixed-wing aircraft and rotary-wing aircraft. Due to the single and fixed layout of these two aircrafts, they still have great limitations in various aspects. Conventional fixed-wing aircraft need to take off and land by taxiing, which has great limitations in the way of taking off and landing, and has strict requirements on the quality of the runway (length, width, hardness, flatness, material, maintenance level, etc.). Although the rotorcraft can reduce the requirements on the quality of the runway, its flight mode makes its flight speed low, the range is short, and the payload is low. Therefore, vertical / short take-off and landing fixed-wing aircraft have emerged as the times require. However, the wings of this type of aircraft...

AI Technical Summary

Problems solved by technology

Therefore, vertical/short take-off and landing fixed-wing aircraft emerged as the times require, but the wings of this type of aircraft are relatively large, and they need to occupy a large space when hovering in the air, and cannot hover and fly in a small space

Although another type of tilt-rotor aircraft can realize vertical take-off and landing and high-speed cruise at the same time, it also has serious defects. The propellers rotate synchronously, which is quite difficult to maneuver and control

In order to overcome these "quality" defects, "O
