Abstract

The invention provides a low resistance and low sonic boom layout supersonic aircraft, and relates to the technical field of supersonic aircraft design. According to the low resistance and low sonic boom layout supersonic aircraft, the canard configuration and the large slenderness ratio aircraft body are used, the aircraft head completely droops, the lower edge of the tip portion upturns, the front undercarriage is forward received into the front undercarriage cabin of the aircraft head, the front portion of the middle-front aircraft body is provided with a full-motion trapezoidal canard having a middle sweepback, the back portion of the middle-front aircraft body and the position in front of the wing are the gas inlet channel of the power system, the middle-rear aircraft body adopts the wasp waist design so as to connect the root portions of the upper wing and the lower wing of the aircraft wings, two jet engines are vertically arranged on the rear aircraft body in a side-by-side manner, the trapezoidal vertical tail having a large sweepback is arranged on the upper portion of the rear aircraft body, and the tip portions of the upper wing and the lower wing of the aircraft wings are connected through the end plate. According to the low resistance and low sonic boom layout supersonic aircraft of the present invention, the shock wave generated due to the wing attack angle is weakened, the sonic boom influence of the shock wave on the ground is reduced, the stability is strong, and safety and reliability are provided.

Description

technical field [0001] The invention relates to the technical field of supersonic aircraft design, in particular to a supersonic aircraft with low-resistance and low-sonic-explosion layout. Background technique [0002] For an aircraft that cruises at high speed in the atmosphere, the aerodynamic layout with minimum drag and maximum lift-to-drag ratio at supersonic speed is its main design goal. However, supersonic cruising flight will generate shock waves. The economical problems caused by wave resistance and the noise pollution caused by sonic explosions have always been the fetters of the development of supersonic aircraft. Especially for supersonic commercial aircraft, how to weaken the impact of the shock wave is always the focus of its layout design. [0003] The shock wave intensity of a supersonic vehicle depends on its own layout and volume. Therefore, the fuselage and wings become the main parts of the aircraft that generate shock waves. A fuselage with a large ...
