Problems solved by technology

However, during the ejection process of the spring, since the matching surface of the ejector rod and the sleeve is a cylindrical surface, the thrust acting on the ejector rod will cause the rotation in the sleeve, resulting in the loss of separation force.

Abstract

The invention provides a limiting type rocket separation impulse providing device based on a spring. The limiting type rocket separation impulse providing device comprises a sleeve and an ejector rod located in the sleeve, one end of the ejector rod extends out of the sleeve, the outer side of the other end of the ejector rod is sleeved with the spring, and a polygonal limiting section is arranged on the outer side wall of the ejector rod. A cavity section matched with the polygonal limiting section in shape is arranged in an inner cavity of the sleeve, limiting holes capable of being matched with a positioning pin are formed in the outer side wall of the ejector rod and the side wall of the sleeve respectively, and the center distance between the limiting hole in the ejector rod and the limiting hole in the sleeve is equal to the working stroke of the spring. The device can ensure that the ejector rod only moves in the axial direction to push the separation section of the rocket along with gradual release of the compression spring, and therefore separation impulse loss is prevented.

Description

[0001] This application is a divisional application of an invention patent application with publication number CN109186376A. The filing date of the original application is: 2018.10.09; the application number is: 201811171392.2; Provide device". technical field [0002] The invention relates to a spring-based limited rocket separation impulse providing device, which belongs to the technical field of rocket separation. Background technique [0003] During the separation process of the rocket separation section from the rocket body, the separation spring device is generally used to provide the separation impulse. The separation spring device is distributed axisymmetrically on the index circle of the rocket separation surface to ensure that the separation route is always along the axial direction. The separation spring device requires simple installation and resetting. Therefore, a sleeve with a cylindrical cavity and a cylindrical ejector rod are usually used to limit the compr...
