Matching design for gas valve flow of solid rocket divert and attitude control motor
摘要
Abstract
The gas valve opening-flow curve design of solid rocket divert and attitude control motor is an important part of improving thrust precision control and working performance of the gas valve.To design a valve opening-flow curve that meets practical requirements,a method for designing pintle profile based on recursive matching was proposed.Initially,when the gas valve was closed,the tangent point between pintle and nozzle was calculated as the initial position.Subsequently,according to the required opening-flow curve,the throat pintle surface was locally linearly expanded,and the coordinates of the pintle profile were recursively calculated based on the dichotomy,and the complete profile of pintle was finally generated.Compared with optimization design algorithms,the above method does not need to preset the pintle parameters,and can quickly obtain the required pintle profile while improving the matching accuracy,thereby realizing a streamlined forward design process.关键词
