Project RecapA hybrid rocket engine is a device that is used to propel an object, generally a rocket, to a user specified point in the atmosphere. The engine can achieve this by converting the chemical energy of the propellants into thermal energy, and ultimately converting that into mechanical energy that imparts a change in momentum on the rocket. The hybrid engine differs from other engines because of the fact it uses a liquid oxidizer, with a separate solid fuel. Separating the fuels makes it inherently safer to store and operate than a traditional liquid or solid motor. The purpose of this project is to build a custom hybrid engine test stand for RIT Launch Initiative to launch a rocket to 30,000 feet at the 2019 Intercollegiate Rocketry and Engineering Competition (IREC). The test stand must be built to withstand the pressure and thrust of the rocket, as well as the cold and hot fire tests that the rocket must go through in order to be launch ready. It must be safe to handle, reusable, high performing, environmentally friendly, and comply with all IREC and government regulations. By year's end, the engine must be ready for tests like the static hot hire test, cold flow test, proof pressure test and system leak test in the bunker on RIT’s campus.
Team Vision for Final Demo and HandoffDuring the final demo and handoff phase of this project, the team members had a goal of finalizing the completed subsystem integration and testing. Given that the hot fire and cold flow tests did not happen, a lot of the components of this projects final steps were not completed. However, all of the customer and engineering requirements were completed in full.
