Team Vision for Problem Definition Phase

The goals and responsibilities of the test team for the Fall of 2018 will be to design, develop, and manufacture a robust test stand for the hybrid rocket engine. The goal of this phase is to communicate with the RIT Launch Initiative as well as the RIT EHS to identify what requirements the test stand must meet to be usable from the stakeholders point of view. Due to the current state of the test stand, and because of its failure to withstand engine failure, a complete remodeling of the test stand is required.The end result was an in-depth project requirements document that maps out our overarching project requirements for our test stand.

Project Summary

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.

Project Goals and Key Deliverables

The main goal of this project is to develop a hybrid rocket engine test stand that can withstand the forest and stress from a test fire at RIT. It will then be passed off to RIT Launch to be used in the 2019 IREC Spaceport America Cup. The project will be considered a success if:

Customer Requirements (Needs)

Customer requirements have been created from the project proposal, the IREC requirements document, and discussions with launch members. The main customer requirements are in the "Level 1" Tab of the "Project Requirements" spreadsheet.
