Abstract

In order to study the loads and responses for structures impacted by exhausted gas jets, a jet impinging plate is investigated numerically, As well as the computational fluid dynamic method are utilized to simulate the jet flow, the finite element method are imposed to calculate structure responses. Simulation results show that: 1) the distribution of the jet impinging pressure was the annular along radial of the plate when the impacting distance is in the specific conditions. The maximum pressure on the plate is about 20%~30% of the total pressure in the rocket motor combustor. 2) For near field jet impinging, the pressure on the plate vibrates with the variation of impingement distance. For far field jet impinging, the load on the plate decreased gragully with the increase of impact distance. 3) The maximum displacement and maximum stress in the steady-state average load analysis were respectively put out by 9.9% and -26.1% with the unsteady analysis’s . And the maximum displacement and maximum stress in maximum load analysis were respectively put out by 96% and 94% with the unsteady analysis .
