Optimization of Nozzle Profiles to Achieve Higher Thrust Performance and Lowering Manufacturing Costs

Weber State University

With the growing popularity in high-powered rockery the question of cost and performance is on every rocketeer’s mind. Then paired with the interest of flying higher and breaking records for armature rocketry flight the question is proposed, how does one make a rocket motor to increase its performance and lower its costs? In this we intend to answer that question. We will design a test for ammonium perchlorate motors and define methods to increase the performance and lower the cost. The way we can achieve this is testing in computer simulations with focused being on nozzle and materials optimization. Computer simulations will help us determine what material may work but also determine what nozzles should be made for physical testing. Then when testing we will design a motor test stand that will have data accusation system to gather the force, P.S.I, and Specific impulse. With the results we can determine what nozzle best increases the impulse and lowers cost for fabrication. The budget for this proposal should be done under $1500 dollars for design of test stand and design of the motor. And to be completed over the course of a year.
