Hybrid Rocket & Come-Back Rover: FAR-ARLISS 2023

Mission Goals

Project Imua Mission 12 involves the participation in two separate but related rocket competitions.  In June, WCC and HCC students will travel to Mojave, CA with their mentor to enter the FAR's 10/25 competition—the challenge is to build a liquid bi-propellant rocket that attains an altitude of 15-20,000 feet and recovered safely and intact.  The FAR’s launch will serve a dual purpose:  1. advance Project Imua’s experience with hybrid motors, and 2. test the payload (consisting of an autonomous rover with atmospheric sensors) that will be flown in the subsequent competition at Black Rock.  Once field tested at FAR, an improved version of this payload will be launched by a solid rocket motor at the ARLISS Come-Back competition at Black Rock, NV. The opportunity to fly the same payload in two different competitions affords the team a chance to enhance the overall design of the autonomous rover for two different environments.  The FAR requirement that the ascent vehicle use a hybrid motor, while ARLISS requires a solid fueled propulsion, gives further opportunity to test the ground safety protocols that could be used for future static propulsion studies at WCC’s Static Rocket Motor Test Facility.
