Solid Proplusion

OVERVIEW

SRL’s Solid Propulsion Team specializes in the development and mixing of high-performance custom composite solid propellants for use in future rocket motors. Raw chemicals are mixed in-house by student members, who follow established procedures and safety standards refined over nearly a decade of experience.

Key Accomplishments

  • Highest thrust solid rocket motor ever produced by a student team: Sledgehammer (6800 lbf)

  • 1200+ lbs of custom ammonium perchlorate composite propellant mixed

  • 100+ solid rocket motor static fire tests

  • 3 P-class and 2 Q-class solid motors mixed

  • Provided the flight motors for all three Mamba rockets

Propellant Mixing & Characterization

Leveraging a wealth of knowledge gained through hundreds of static fire tests, the team have developed and characterized two unique propellants, Quicksand and Sandstorm. These propellants are mixed in-house from raw chemicals, and processed using vibration and vacuum to achieve a highly consistent result. Propellant geometries are designed using in-house internal ballistics analysis tools.


Motor Hardware

Additionally, the propulsion team designs and manufactures custom rocket nozzles, forward motor enclosures and other motor components. These components are also made fully in-house at machine shops around the CU Boulder campus.

Motor Hardware:

  • Aluminum Forward Bulkhead

  • Fiberglass G10 Insulation Disk

  • Phenolic & Graphite Nozzle

  • Motor Retention Hardware
