An escape device for manned rocket based on aerodynamic force and its working method

Abstract

The invention discloses a novel escape device and working method for a manned ket based on aerodynamic force. The escape device includes a fairing, a ket body positioning module, a ket body, a ket body fixing module, a primary fuel storage tank, a ket skeleton and a ket body rotation module , the ket frame is connected with the ket body through the ket body rotation module, the ket body rotation module includes the ket frame connection seat, the rotation pin and the ket body connection block, the ket body connection block is connected with the ket body, and the ket frame connection seat is connected with the ket frame , the connecting block of the ket body and the connecting seat of the ket frame are connected in rotation through a rotating pin, and the outer wall of the first-stage fuel storage tank and the inner wall of the rotating module of the ket body are provided with corresponding cylindrical grooves, and the fixing module of the ket body also includes a The arrow body fixing hook under the spring is provided with a retractable arrow body fixing column at the position opposite to the arrow body fixing hook on the first-level fuel tank, and a positioning pin is arranged at the position corresponding to the arrow body joint at the lower part of the fairing. The upper parts of the adjacent two ket bodies form a positioning groove.

Description

Technical field: [0001] The invention relates to a manned rocket, in particular to an escape device for a manned rocket based on aerodynamic force and a working method thereof. Background technique: [0002] The classic escape towers are all designed on the upper part of the fairing, resulting in a slender and bulky fairing above the rocket. The existing rocket escape towers use the pulling force of the escape engine to pull the orbital module and the return module away from the rocket to help astronauts escape, but escape The tower has great aerodynamic resistance, so the rocket engine is required to provide a lot of thrust, and the thrust requirement of the rocket engine is relatively high. The classic escape device escape method is to pull the rocket's orbital module and return module away from the rocket body under the strong pulling force of the escape engine, and land safely on the ground. However, in such an escape method, the rocket body constrains the escape device...

AI Technical Summary

Problems solved by technology

However, in this way of escape, the rocket body constrains the escape device greatly during escape, that is, the escape device is in a non-free state when escaping, and part of the energy consumption of the escape engine increases the escape time during the process of releasing the restraint of the rocket body.
