Overview

Scorpion is a bipropellant liquid rocket engine. It utilizes a kerosene and liquid oxygen propellant combination and features an unlike impinging-jet injector, an ablative thermal protection system, and a modular two-part nozzle. All components are designed, manufactured, tested, and analyzed in-house by CU SRL students.

Specifications:

Thrust: 1,200 lbf
Chamber Pressure: 700 psi
Chamber Temperature: 5,894 °F
Injector Type: Unlike impinging-jet
Thermal Protection: Ablative
Diameter: 5.5 in

The Scorpion program aims to complete a series of static fire tests during the 2026–2027 academic year to validate performance and inform iterative design improvements. Following successful ground testing, the team plans to integrate Scorpion into a flight vehicle to compete in the FAR Dollar-per-Foot Challenge.
