Embodiment Construction
[0071] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered by the claims.
[0072] The invention provides a progressive matching design method for solid rocket motor performance, comprising:
[0073] Obtain the mission objective of the solid rocket motor overall index;
[0074] Determine the number of divided time intervals and the length of the time interval according to the working time of the preset thrust requirement in the task target;
[0075] The initial training sample X of the preset thrust requirement matching degree is obtained based on the initial equilibrium pressure method i (i=1,2,...,N);
[0076] According to the initial training sample, run the burning surface and the internal ballistic calculation model in the initial time interval to obtain corresponding N thrust curves in the initial time interval, and constr...
