Advanced Hybrid Rocket Motor Propulsion Unit for CubeSats (PUC) Testing

This project will demonstrate a novel propulsion unit that utilizes a hybrid rocket motor. Hybrid rocket motors are an attractive bipropellant for use with CubeSats because unlike solid rocket motors, hybrid motors are not necessarily single-use thrusters and might be used for small time duration thrust events like those needed for stationkeeping or orientation control when a suitable igniter system is employed. They also can be used in longer duration burns for deorbit maneuvers or orbit insertion. Since one of the two propellants is a solid material they have much greater simplicity and lower weight considerations than bipropellant options using all liquid propellants. The propulsion unit will be designed to be compatible with the existing footprint of CubeSats. The combination of current state-of-the-art rapid prototyping of hybrid motor with current manufacturing of propellant systems in CubeSats could conceivably produce a high thrust bipropellant motor in a compact space that should easily outperform existing cold gas thruster technology on existing CubeSats and could easily incorporate many existing techniques used to produce propulsion units in CubeSats.

The hybrid bipropellant rocket motor is attractive for CubeSats in small time duration thrust events, orientation control or longer duration burns for deorbit maneuvers or orbit insertion, since it has much greater simplicity and lower weight considerations than bipropellant options using all liquid propellants.

This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
