Abstract

The invention relates to a side air inlet high-speed aircraft. The side air inlet high-speed aircraft comprises an aircraft body, a lower wing face is arranged below the aircraft body, a high-pressurecapture wing is arranged above the aircraft body, an air suction type engine is arranged in the aircraft body, air inlets are formed in the front end of the air suction type engine, a cone body and gas runners are sequentially arranged below the lower wing face from front to back, the cone body extends from the front portion of the aircraft to the rear portion and the lower portion of the aircraft, the width of the cone body is smaller than the width of the corresponding lower wing face, the gas runners are located on the two sides of the cone body, the air inlets of the air suction type engine are located behind the gas runners, the air suction type engine is mounted below the lower wing face, the belly space of the aircraft body is released, and can completely serve as a lifting surfaceto be used, the air inlets are placed on the two sides of the front end of the aircraft, the wave-riding forebody design is adopted, uniform compression characteristics of the wave-riding forebody can be sufficiently used, on one hand, the engine property can be effectively improved, and on the other hand, the wave-riding forebody can effectively improve the whole machine lift-drag ratio.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of high-speed aircraft devices, in particular to a side-intake high-speed aircraft. Background technique [0002] High-speed aircraft mainly refers to various types of supersonic or hypersonic aircraft. Generally, the flight whose Mach number M is 1.2-5.0 is called supersonic flight; the flight whose Mach number M is greater than 5.0 is called hypersonic flight. The configuration design of new high-speed aircraft is a hot issue in the development of aircraft, especially the configuration design of high lift-to-drag ratio with power. [0003] In the prior art, one type is an unpowered gliding aircraft. By arranging an upper-mounted capture wing above the aircraft, the lift-to-drag ratio can be effectively improved, such as CN103350750A, which is provided with a high-voltage capture wing above the aircraft body; another example is CN104354852A. A high-speed aircraft is provided, which h...
