Abstract
Abstract
The solid rocket motor is extremely widely used due to its many advantages, but the solid rocket motor also has the disadvantage that the thrust cannot be changed. To solve this problem, there are generally two solutions to this problem. One is to use a mechanical pintle structure to change the effective cross-sectional area of the nozzle, and then to change the size of the thrust. The other is to change the effective cross-sectional area through the secondary jet method. These two methods all can change the size of the thrust, but they also have their drawbacks. The domestic team proposed a plan that combines the two methods to make up for each other’s shortcomings.
