The solid rocket propellant [Name TBD] Deimos, previously called "Propellant XBlue Voltage" in development, was developed for Project Medusa with initial mixing and testing in April 2023 and finalized in September 2023.
History and Purpose
After the successful manufacturing and launch of Phoenix in January 2023, the team created goals for the next Spaceshot rocket, Project Medusa. One of the Medusa goals are to get halfway to space (~185,000 feet). Therefore, it was clear that a new propellant was necessary to fit the project's goals. Initial propellant formulas were developed in spring 2023, and characterization tests occurred throughout summer 2023. Lack of AP access slowed down the process in late summer-early fall 2023.
Goals for this formula:
- Experiment with trimodal AP
- Experiment with burn rate modifiers
Changes from previous propellant (Cherry Limeade):
- Experiment with trimodal AP
- Experiment with burn rate modifiers
- Replaced HTPB with a new bonding agent to combine HTPB and Tepanol bonding agent
