Embodiment Construction

[0021] Such as figure 1 and figure 2 As shown, the air source device for an aircraft based on high-speed flow energy and shock wave boosting in this embodiment includes a windward concave cavity 1, an air collection tank 2 and an air supply adjustment assembly 3, and the windward concave cavity 1 is arranged on the blunt body of the aircraft , the windward concave cavity 1, the gas collecting tank 2, and the air supply regulating assembly 3 are connected in turn through the gas pipeline. The working gas source of this embodiment is not provided by the high-pressure gas cylinders carried from the ground, but is directly obtained from the high-altitude atmosphere by means of the flying speed of the aircraft, that is, the "high-speed flow energy / shock wave supercharging principle". High-pressure gas cylinders are carried on the ground. This gas collection method greatly simplifies the design of the gas collection system and reduces the weight that the aircraft needs to carry.

Abstract

The invention discloses a gas source device based on high speed flow energy and shock wave pressurization and used for an aircraft. The gas source device includes a windward concave cavity (1), a gas collecting pot (2) and a gas supply adjustment assembly (3). The windward concave cavity (1) is arranged on a blunt body of the aircraft. The windward concave cavity (1), the gas collecting pot (2) and the gas supply adjustment assembly (3) are communicated with each other through gas conveying pipelines. A one-way valve (4) allowing high-pressure gas in the gas collecting pot (2) to flow out reversely is disposed on the gas conveying pipeline between the windward concave cavity (1) and the gas collecting pot (2). A lip part of the windward concave cavity (1) is pointed or circular in shape. The gas source device is free of a gas source in itself, is good in pressurization effect, is suitable in high-altitude thin atmosphere environment, can greatly reduce the mass of the aircraft, has a wide application scope, and has a more significant effect of reducing a pneumatic heating amount on a head part of the blunt body.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to an air source device for aircraft based on high-speed flow energy and shock wave boosting. Background technique [0002] Aerodynamic control is one of the main challenges of high-speed aircraft. DARPA's hypersonic aircraft HTV-2 crashed after nine minutes of flight because the aircraft control system could not correct the yaw; the second flight test added mass-corrected moving parts, But in the end, it crashed after twelve minutes of flight due to the same flight control problem. [0003] Side jet direct force control is an effective control method for high-speed aircraft, which has the characteristics of strong maneuverability and high control efficiency. Side jet direct force control is to control the attitude or trajectory of the aircraft through the reaction force generated by jetting gas outward at high speed. Widely used in various spacecraft, for example, the reaction control sys...
