Low Cost Hybrid Rocket Orbital Transfer Stage

Parabilis Space Technologies is pleased to propose the development of a high-performance hybrid rocket stage suitable for both small spacecraft maneuvering and for trans-lunar orbit injection in response to solicitation Z8.09, Small Spacecraft Transfer Stage Development. This effort leverages previous successful NASA-funded Ramp;D at Parabilis for a ldquo;NanoLaunchrdquo; hybrid upper stage and the design of an appropriately scaled-up hybrid motor. The proposed stage is economical, non-toxic, non-cryogenic, restartable, and compatible with multiple ldquo;venture-classrdquo; launch vehicles.nbsp; The stage will be offered in two sizes, one of which will be capable of delivering 25 kg payloads into translunar trajectories when launched abord a rocket-lab electron vehicle. A larger ldquo;granderdquo; stage will be capable of injecting 60 kg payloads into translunar trajectories when launched aboard a Virgin Orbit LauncherOne, Firefly Aerospace Alpha, or Relativity Space Terran 1. There also a clear path to the creation of larger stages that maximize the payload capacity of Terran 1 or ABLrsquo;s RS1.nbsp;During Phase I, Parabilis will design, manufacture, and hot flow test a relevant scale prototype motor, significantly burning down both technical risk and the effort required for flight-like prototypes which will be tested in a subsequent Phase II effort. This development effort leverages a design from a previous NASA SBIR. This approach will rapidly and substantively reduce risk for further Phase II development.
