A variable configuration two-body unmanned aerial vehicle spanning water and air medium

Abstract

The invention discloses a variable-configuration dual-body unmanned aerial vehicle capable of crossing water and air mediums. Two vehicle bodies are symmetrically arranged and connected through a middle wing and an empennage; wings on the outer side can change the sweepback angle around a rotating shaft, during flying in air, the wings are unfolded, and during underwater submerge, the wings sweepback and are accommodated to the two sides of the vehicle bodies; wing body rectification and the wing shape are subjected to smooth transition, a water rudder is arranged at the bottom of the rear vehicle body, the empennage is arranged in an inverted-V shape, and underwater propellers are mounted at the tail parts of the vehicle bodies; and aerial motors and aerial screw propellers are mounted in the middles of the vehicle bodies through motor towers, the motor towers can topple over backwards around the rotating shaft and are accommodated in the vehicle bodies, and after toppling over, thescrew propellers are attached to the upper surfaces of the vehicle bodies. According to the variable-configuration dual-body unmanned aerial vehicle capable of crossing the water and air mediums, design methods of an air vehicle and a submersible device are integrated, continuous crossing of the water and air interface for many times can be achieved, the variable-configuration dual-body unmanned aerial vehicle continuously navigates in the two mediums, control stability performance is good, the loading capacity is high, and the variable-configuration dual-body unmanned aerial vehicle can carryout tasks such as concealment, defense penetration, investigation, striking and the like.

Description

technical field [0001] The invention relates to the field of aircraft and submarines, in particular to a double-body unmanned aircraft with a variable configuration that crosses the water-air medium. Background technique [0002] The water-air medium vehicle is a new concept vehicle that adapts to both air and water media environments, can cross the water-air interface multiple times and can continue to sail in the two media. The water-air medium vehicle has two configurations of air flight and underwater submersion, and the configuration conversion can be realized through structural variants. Its navigation mode can be divided into air flight mode, near water surface flight mode, water surface entry and exit mode, and underwater submerged mode. It can use the blind spots of various detection equipment to switch sea and air navigation modes to avoid enemy surveillance, and can be used to perform maritime reconnaissance , combat, special force projection and other missions. ...
