Problems solved by technology

The disadvantage of this method is that there is no charge inside the front head, its volume is not effectively used, and a separate front skirt needs to be installed on the booster for inter-stage connection. It is difficult to reduce the overall length of the aircraft, which is not conducive to reducing the size of the aircraft. scale and weight scale

Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] The present invention adopts an integrated design structure of the rear section of the interstage connection section and the front head of the booster. The inner and outer walls of the front section of the interstage connection section are flush with the tail section of the cruise stage, and the outer surface of the rear section of the interstage connection section is tangent to the transitional outer surface on the front head of the booster. The shape of the front head of the booster is horizontal. Ellipsoid, charged inside the front head.

[0019] attached figure 2 Among them, 4 is the tail section of the cruise stage, 5 is the connecting section between stages, and 6 is the front head of the booster.

[0020] d is the outer diameter of the tail section of the cruise stage, d1 is the inner diameter of the tail section of the cruise stage, both d a...

Abstract

The invention discloses an integrated structure of an interstage connection section of an aircraft and a front head of a booster. The transition surface on the front head is tangent, the shape of the front head of the booster is a transverse ellipsoid, and the inside of the front head is charged. The present invention adopts the integrated structure of the connecting section between stages and the front head of the booster, and the booster has no front skirt. The inside of the front head can not only charge the powder but also simultaneously bear the force, which is beneficial to reduce the launch size and quality of the aircraft.

Description

technical field [0001] The invention belongs to the technical field of aircraft shape design, and in particular relates to a connection structure between an aircraft interstage connecting section and a booster. Background technique [0002] A high-speed cruise vehicle usually consists of a solid rocket booster (hereinafter referred to as a booster), a cruise stage, and an interstage connecting section. The function of the interstage connecting section is to connect the cruise stage and the booster in series. The common practice of existing aircraft is to arrange the front skirt at the front end of the booster (see the attached manual). figure 1 , 1 is the front head in the figure, 2 is the front skirt, and 3 is the engine body), and then the front skirt is connected with the cruise stage through the interstage connecting section. The disadvantage of this approach is that there is no charge inside the front head, its volume is not effectively utilized, and a separate front ...
