Development of the Fast-Acting, Deep-Throttling Hybrid Motor

Completed TRL 4 (started at 2, targeting 4)

Description

The goal of this proposal is to test and analyze the performance of a well-characterized, Utah State University (USU) developed, deep-throttling hybrid motor in conjunction with MSFC ER14's developed Fast-Acting Digital Valve. The oxidizer flow control valve that is currently utilized by USU has poor fidelity and slow response times, which are shortcomings that the Digital Valve addresses. The combination of these two components provides the opportunity for the development of a Fast-Acting, Deep-Throttling, Hybrid Motor that is capable of both upper stage main propulsion and reaction control with the same motor.

Benefits

This proposed solution has bi-modal capability for both intermediate- (<250N) MPS and low-thrust RCS Propulsion (<10N) operations with same motor. Such advanced propulsion systems could be utilized for small lunar/mars landers and various launch assist vehicles.

How to get involved

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.
