Cross-medium aircraft with variable structure

Abstract

The invention relates to a cross-medium aircraft with a variable structure. The cross-medium aircraft comprises a fuselage, foldable wings, an adjustable vertical tail, an adjustable horizontal tail, a water jet propulsion device and foldable propellers. The foldable wings comprise a left wing and a right wing which are symmetrically installed on the two sides of the front portion of the fuselage, and folding and unfolding are achieved through a multi-degree-of-freedom adjusting mechanism. The adjustable vertical empennage is installed on the upper side of the tail of the aircraft body and used for adjusting the advancing direction of the cross-medium aircraft in the air or underwater. The adjustable horizontal empennage comprises a left empennage and a right empennage which are symmetrically installed on the two sides of the tail of the aircraft body and used for achieving floating or diving of the cross-medium aircraft in water. The water jet propulsion device is installed at the tail of the aircraft body and used for providing underwater advancing power for the cross-medium aircraft. The foldable propeller is installed on the head of the fuselage. According to the cross-medium aircraft, through the variable structure design, the underwater resistance is effectively reduced, and the amphibious cross-medium navigation capacity of underwater high speed, high maneuverability and aerial high-speed flight is achieved.

Description

Technical field [0001] The present disclosure relates to the technical field of water-air transmedia aircraft, in particular to a transmedia aircraft of a variable structure. Background [0002] In order to expand the operating environment and application scope of existing aircraft, and make full use of the advantages of high concealment of underwater navigation and high maneuverability of air flight, aviation scientific and technological personnel in various countries have begun to shift their attention to water-air transmedia vehicles with water-air amphibious viability. [0003] The water-air transmedia aircraft is a new amphibious multi-functional equipment that integrates the advantages of aircraft and submarines, can circulate in the air and underwater, and perform military tasks such as reconnaissance, vigilance, and penetration, as well as civilian tasks such as marine resources exploration, search and rescue, and water quality testing, and has high mobility, concealment ...

AI Technical Summary

Problems solved by technology

[0004] However, because the core technology of water-air cross-media aircraft covers a wide range of professional fields and technical difficulties, it involves both underwater and air media, and is different from traditional aircraft and aircraft in terms of overall layout, structural form, and control system.
