Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] figure 1 , 2 Side and bottom views of the hooded hypersonic vehicle are shown. Figure 3-7 Clarified the process of jettisoning a hypersonic vehicle's "tie-up" bonnet, image 3 For the case where the cap is fixed on the hypersonic vehicle, Figure 4 is the position where the baffle is opened by the explosive bolt, Figure 5 In order to pull the whole hood away from the hypersonic vehicle under the action of aerodynamic force, Figure 6 and Figure 7 Shows the position of the visor relative to the aircraft after jettison.

[0020] The "pulling type" discarding scheme of the hypersonic aircraft cap of the present invention includes an aircraft main body 1 and a cap, the cap includes a cap main body 2 and a baffle 3, the cap main body 2 is fixed on the aircraft main body 1, and the baffle 3 It is fixed on the cap main body 2 by explosive bolt...

Abstract

The invention discloses an implication type cover hood abandoning scheme for a hypersonic aircraft, and belongs to the technical field of aerodynamic designing of hypersonic aircrafts. In the abandoning scheme, an aircraft body, a cover hood body and a baffle are adopted, the cover hood body is fixed on the aircraft body, and the baffle is fixed on the cover hood body; with regard to abandoning a cover hood, firstly, the baffle is opened by a certain angle through an explosive bolt, and then the whole cover hood comprising the cover hood body and the baffle are stripped from the aircraft body through aerodynamic force. According to the implication type cover hood abandoning scheme for the hypersonic aircraft, the cover hood can be quickly stripped from the hypersonic aircraft so that air can smoothly enter the aircraft.

Description

technical field [0001] The invention relates to a "pulling type" cap discarding scheme of a hypersonic vehicle, which belongs to the field of aerodynamic design of a hypersonic vehicle. Background technique [0002] A hypersonic vehicle generally refers to an aircraft whose flight speed exceeds Mach 5.0. Hypersonic aircraft can realize the vision of "going around the world in one hour". One of the key technologies to achieve hypersonic flight is the power plant. At the current technical level, it is still impossible to accelerate the aircraft from a static state to a hypersonic flight state by a single air-breathing engine. For the problem of power plant, the main solution at home and abroad is to use combined engines, including Turbine Based Combined Cycle (TBCC) and Rocket Based Combined Cycle (Rocket Based Combined Cycle, RBCC). [0003] Among them, due to the high technical difficulty, TBCC engines have not yet been used on hypersonic aircraft at home and abroad, whil...
