AI Technical Summary

Technical Problem

Existing technologies cannot effectively simulate the impact of high overload environments on solid rocket engines during missile flight, resulting in discrepancies between ground simulation test results and actual performance. Flight tests are costly, non-adjustable, and difficult to control.

Method used

A high overload ablation test device was designed, comprising a test device foundation, a high-speed turntable, a support system, a transmission system, an electrical system, and a measurement and control system. The high-speed turntable generates overload acceleration, and laser ignition and a line scan camera are used for real-time monitoring and data acquisition to evaluate the high overload ablation performance of solid rocket motors.

Benefits of technology

It achieves realistic simulation of solid rocket motors under high overload conditions, improves test accuracy and controllability, reduces test costs, and improves test efficiency and repeatability. It is suitable for simultaneous testing of multiple engines.
