Abstract

The invention relates to the field of aircraft conceptual designs, in particular to a morphing supersonic aircraft. The morphing supersonic aircraft includes a plane body, two wings (1) and an undercarriage. According to the morphing supersonic aircraft, mode translations from a subsonic flight condition to an supersonic flight condition can be achieved through a pre-transformation swept wing mechanism (2), under the conditions of subsonic flight and takeoff and landing, and leading edge high aspect ratio wings are adopted to reduce the induced resistance and increase the subsonic voyage; andunder the supersonic flight condition, tip leading edge low aspect ratio wings are adopted to reduce the wave drag, and the maneuverability can be improved. According to the morphing supersonic aircraft, aircraft can splendidly give consideration to the operating requirements of high speed and low speed, passenger cabins, cargo compartments, fuel tanks and ear compartments are all arranged in twowings (1), obvious plane body does not exist, and the weight of the plane is reduced to some degree.

Description

technical field [0001] The invention relates to the field of overall design of aircraft, in particular to a large variant supersonic aircraft. Background technique [0002] Now the demand for air transport is increasing year by year, especially in Asia, where the economy is developing rapidly, the increase in demand is more significant. Under this demand, the capacity of air transport is approaching the limit, and the countermeasure is to vigorously develop larger and higher-speed aircraft all over the world. [0003] The existing layout of supersonic transport aircraft can be divided into four categories. 1. Small aspect ratio wings are adopted, and the aircraft’s aerodynamic efficiency is low during subsonic flight and take-off and landing stages of this type of layout; 2. Variable rear (front) swept wings are adopted, and this type of layout has a large weight of the aircraft body, and the wings are swept back Angle changes bring about large changes in the focus of the ...
