Build & Test Prep
Table of Contents
A 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 Build & Test Prep PhaseIn the short time since the beginning of the semester, the team has focused on getting each subsystem prepared for testing. Due to the nature of the project, many subsystems will be very easy to test independently of each other, while we will only know that other engineering requirements are met upon launch. As such, additional time has been focused on ensuring the integrity of the design to increase the probability of success. During this phase, the team worked on creating test plans and doing some pre-testing setup, to make the next phase go smoothly and follow a specific procedure. Our risk/problem assessment was updated, and the team had several discussions about how we would approach any unexpected situations.
