NUMERICAL SIMULATION OF BURNING GAS FLOW FIELD BASED ON THE BASE BLEED PRINCIPLE WITH FLOW CONTROLLING |
| |
| Abstract: | A base bleed principle with flow controlling is a new technology. It can be used to change the fire precision of the base bleed projectile, and to improve the effect of drag reduction and range expansion. Combined with the characteristic analysis of the traditional base bleed principle, the pressure condition of flow controlling is deduced. The numerical simulation results based on pressure and velocity flow field is introduced. The results of calculation are closed to that of the experiments. |
