IREC Hybrid Rocket

The IREC Hybrid Rocket team, let by Ellen Yang ’20, will design and construct a pressure-fed hybrid motor rocket, with the end goal of competing in the 2018 Intercollegiate Rocket Engineering Competition (IREC) in the 10,000 ft. AGL apogee student researched and developed (SRAD) hybrid or
liquid propulsion system category.

By the end of the 2017 spring semester, YUAA had a competition-ready hybrid motor that uses rubber as fuel and liquid nitrous oxide as oxidizer. Ellen’s project intends to take the lessons learned from the previous year’s project and continue exploring hybrid motors by refining the previous year’s design. This project will build upon a previous hybrid motor project by replacing commercial off-the-shelf (COTS) components with student designed and machined parts (i.e. a customized nozzle machined from graphite stock). Doing so allows YUAA to optimize the motor design at a lower cost. This team will also design and build their own ground support equipment. These steps will help lead to YUAA eventually designing and building a liquid-fueled engine in the near future, as liquid engine design draws upon many of the concepts explored through hybrids. It will also be the first hybrid rocket launched by the Yale Undergraduate Aerospace Association (YUAA). Moreover, it will continue YUAA’s efforts to gain experience with hybrids with the interest of building a fully liquid rocket engine in the next five years.
