Precise Design of Solid Rocket Motor Heat Insulation Layer Thickness under Nonuniform Dynamic Burning Rate

Procedure 3

Compute exposure duration.

Input: for each sample point, data of the SRM

1: Discretize into a sequence of length such that

2: Build the propagation distance data sequence of length

3: , assign ,

4: for all sampling sections parallel do

5: In sequence , find the first such that ,

6: Perform a linear interpolation within interval , find such that ,

7: end for

8: return For all the sample points, is the exposure duration.
