Oregon State University's 2021-2022 High Altitude Rocket Team (HART) is a student-run Capstone project under the OSU branch of AIAA, with the goal of designing, manufacturing, and successfully launching and recovering a two-stage solid motor rocket to a target altitude of 150,000ft above ground level. Each year, HART has the ambitious goal of completing a range of projects, including L1 and L2 certification flights, a subscale two-stage dubbed the name “Frankencow”, a full-scale Boosted Dart launch with a mock weight in the second stage, and the final full-scale two-stage launch in Black Rock, NV or Spaceport, NM. In addition to these launches, static test fires, ejection testing, strength testing, data acquisition, and simulation analysis were all very important to our progression throughout the year. Manufacturing was essential to bring our ideas to reality and incorporated machining various metal parts, 3D printing two avionics bays, completing carbon fiber layups, cutting fiberglass parts with the waterjet, mixing motor propellant, and constructing various jigs to ensure accurate assembly. HART used two student-researched and -developed solid rocket motors (“Liquid Sand” and “Black Flame”). The team started off with two successful subscale “Frankencow” launches, being the first fully successful two-stage launch and recovery at OSU. HART also launched a Single Stage rocket with our “Liquid Sand” motor to an altitude of 28,100ft. HART’s final two-stage launch at Black Rock, NV had a successful booster ignition, but the second stage did not ignite because the tilt angle exceeded the pre-programmed 15 degree lockout.
