Popis: |
The work performed in this effort used previously measured experimental subscale hybrid propellant data to develop a ground test motor in the 1000 pound-force range. This ground test motor was test fired and the test data was used to finalize a motor fuel grain geometry configuration and an oxidizer injector geometry. The ground tests were then used to finalize the hybrid motor configuration that was used in the three flight test vehicles. The ballistic hybrid motor analysis presented here was developed using the test data to determine what parameters had the greatest impact on obtaining good agreement with the ground tests data. The analysis consists of solving a single ordinary differential equation for the motor chamber pressure. The oxidizer flow rate is coupled to the motor chamber pressure and the motor combustion gases are represented as a function of oxidizer to fuel ratio. The work performed demonstrated hybrid rocket motor performance comparable to ammonium perchlorate-HTPB systems but with a must greater degree of hazard insensitivity and a demonstrated variable thrust control capability |
