In 2024, SARP returned to compete in the Spaceport America Cup, the premier international collegiate rocketry competition, for the first time since 2019. Our 2024 entry into the 10,000ft altitude category, Short King, showcased the team’s ability to design and fly a rocket multiple times from the ground up in less than a year. Powered by a commercial solid motor, Short King introduced and successfully demonstrated modular payload and composite aerostructure designs for the team. For 2025, SARP is advancing to the prestigious 30,000ft altitude category and entering our first student-developed solid rocket motor. The 2025 Spaceport America Cup entry will increase the use of composite materials to reach a maximum velocity of Mach 2.0 on its way to set the team’s altitude record.
SARP has big goals in liquid rocketry, but those goals need to start somewhere. This year SARP will make history at the University of Washington, with our first successful liquid rocket, DomeCracker. We will be making our first appearance at the Friends of Amateur Rocketry - Oxidizers Uninhibited Tournament (FAR-OUT) competition with DomeCracker in 2025 in the 5,000-15,000ft category, establishing our name in the liquid rocketry space. For DomeCracker, we are using a simple ablatively cooled liquid engine that injects ethanol and nitrous oxide using coaxial swirl injectors.
Testing infrastructure is the backbone of what we do at SARP. All of our technologies have to be adequately vetted before we use them in the field. As an integral part of our design process, significant resources have been diverted towards preparing durable and reliable testing equipment that enables the team to iterate efficiently.
