Solid rocket vehicle

Abstract

The invention discloses a solid rocket vehicle, and belongs to the field of recyclable rocket design. The solid rocket vehicle specifically comprises a head load compartment, a rocket body, wings, a rudder, horizontal tail rudders, an adjustable gas flow baffle, ad a tilt buffer; the head load compartment is in a lifting-body shape, the wings are located on both sides of the middle of the rocket body, and the horizontal tail rudders are located on both sides of the rear of the rocket body; and the rudder is located on the back of the rocket body, and the adjustable gas flow baffle is mounted on the rocket body and placed at the lower back portion of the outlet of an engine nozzle. The solid rocket vehicle comprehensively applies the lifting-body load compartment, the wing-level full-actingtail rudders and the landing buffer to increase the lifting force of a flight test platform, and the lift-block ratio and the delay time of the flight test platform are improved, so that the cruisingcapability of the flight test platform is improved; and the method of control rolling rotating of the differential horizontal tail rudders is used, the complexity of a control mechanism is simplified, the self-control of the drop point is achieved by using the cruising capability and the tilt strategies of the flight test platform, and landing recovery is easier.

Description

technical field [0001] The invention relates to a solid rocket vehicle, in particular to a solid rocket vehicle suitable for parachute recovery, and belongs to the field of recoverable rocket design. Background technique [0002] Flight test, wind tunnel test, and numerical calculation are called the three major means of aircraft aerodynamics research. As a supplement and verification of ground test, flight test has received more and more attention in the field of high-speed aerodynamics in recent years. However, single preparation for traditional high-speed flight tests is time-consuming and costly. Therefore, relying on recycling to reduce test preparation time and costs has become the only way for the development of flight tests. Judging from the recovery experience of traditional launch vehicles, parachute recovery is an important way to solve the low cost. For example, the US space shuttle booster stage has successfully completed more than 80 recoveries relying on the p...

Problems solved by technology

[0003] However, most of the current aerodynamic layouts of high-speed flight test platforms are not suitable for direct use of launch vehicle parachute recovery schemes. The action pressure is high, it is difficult to meet the conditions for opening the parachute

Even if the parachute recovery technology is used through certain improvements, the lift-to-drag ratio of the test platform under the traditional aircraft layout scheme is very low, the cruise capability is poor, the controllable air stay time is short, and it cannot fly to the designated location. The recovery point is restricted by mission-level ballistics. Unable to specify drop point
