Multifunctional wing capable of rotating to vertical state for safe separation

Abstract

The invention belongs to the technical field of aircrafts, and particularly relates to a multifunctional wing capable of rotating to a vertical state and being safely separated. The whole wing is composed of an inner wing, a middle wing and an outer wing, an inner wing tip chord is connected with a middle wing root chord, a rotating shaft is arranged at the joint, the middle wing and the outer wing can integrally rotate around the rotating shaft, the maximum rotating angle can be rotated to be perpendicular to the inner wing, a middle wing tip chord is connected with an outer wing root chord,and the outer wing can be separated from the middle wing. The inner wing serves as an aircraft fixing structure, and an internal cavity can be loaded with loading equipment and fuel oil; the middle wing serves as a connecting structure of the inner wing and the outer wing, the wing section with the small relative thickness is adopted, an internal cavity can be loaded with loading equipment, and the middle wing can be used as a vertical fin after rotating. The outer wing is of a separable structure and can be separated from the middle wing after rotating in place, the symmetrical wing type withthe large relative thickness is adopted, and fuel oil can be added into an inner cavity.

Description

technical field [0001] The invention belongs to the technical field of aircraft, and in particular relates to a multifunctional wing that can be rotated to a vertical state and separated safely. Background technique [0002] With the development of science and technology, the application mode of aircraft in the future will change. The change of application mode of aircraft needs flexible flight mode as support. The flight mode of future aircraft will add two important features: one is wide-speed flight, and the other is It is a cross-domain flight. Wide-speed flight refers to breaking through the subsonic and supersonic flight speed domains and expanding to hypersonic flight speed domains, that is, expanding from flight speeds to Mach 5 or above; cross-domain flight refers to breaking through the traditional low-altitude, medium-high altitude flight airspace and expanding to adjacent spaces , The space domain, that is, extending from the flight altitude to more than 100 kil...

AI Technical Summary

Problems solved by technology

In the past, hypersonic vehicles were limited by the positioning of mission requirements and the technical level. Generally, the maximum Mach number or cruising Mach number was used as a single design point, and the flight speed range that could maintain high aerodynamic performance was narrow. Aerodynamic performance is difficult to get a good balance
