Small-sized combined type air vehicle adopting layout combining disk swing with variable wings and airbag

Abstract

A small-sized combined type air vehicle adopting a layout combining a disk swing with variable wings and an airbag comprises an empennage portion, a variable wing portion, a disk swing portion and a support portion, wherein the empennage portion is fixed on a base of the support portion through a crossbeam limiting hole on a crossbeam bottom seat of the variable wing portion, the variable wing portion is positioned on the upper portion of the disk swing portion and penetrates through a crossbeam hexagonal limiting hole on the crossbeam bottom seat through a longitudinal through bolt so that the crossbeam bottom seat is matched with the upper surface and the outer side of an inner shell of the disk swing portion, and the variable wing portion is fixedly connected with the disk swing portion. The disk swing portion is positioned on the upper portion of the support portion, and six longitudinal through bolts of the disk swing portion penetrate through six equant limiting holes of the base so that the disk swing portion is connected with the support portion. By adopting the disk swing technology and the variable wing technology, the medium-sized air vehicle is all-weather and capable of realizing vertical takeoff, horizontal flight and rapid floating on the sea surface. The small-sized combined type air vehicle is applicable to sea rescue, low-altitude and high-altitude cruising and proceeding on complicated terrains and can meet needs of various tasks.

Description

technical field [0001] The invention relates to a small combined aircraft that adopts the layout of disc wings combined with variable wings and airbags. It integrates the air outlet characteristics of the disc wings and designs the switching of two flying attitudes, and can simultaneously complete the tasks of high-altitude and ground-air flight , belongs to the field of aircraft model technology. Background technique [0002] Airships have a long history as the first aircraft to go to the sky. Later, it gradually faded out of the mainstream aircraft due to its speed, handling and other issues. In recent years, energy issues have attracted much attention, and airships, especially modern combined airships, have re-emphasized their practical value compared with other aircraft due to their relatively low price and moderate performance. At the same time, a power scheme called disc wing was born, which can provide lift and near-earth and offshore air cushion effects, making it ...

AI Technical Summary

Problems solved by technology

The density of the aircraft itself is higher than that of the air, and it is driven by power; its fixed wings provide lift to enable the aircraft to soar in the sky, so the aircraft's speed and direction maneuverability are very superior, but there are strict restrictions on the flight speed
