Technical Abstract (Limit 2000 characters, approximately 200 words):

The proposed innovations are as follows:
1. Rotating detonation engine (RDE) injector using Masten’s patent-pending permeable additive manufacturing (PermiAM) method, which provides improved propellant distribution and cooling in the engine relative to traditional injector methods.
2. Liquid-liquid injector using liquid oxygen (LOX)/Methane.
3. The ability to manufacture single parts with varying material properties will enable cost savings in areas where, in the past, multiple components required manufacturing and assembly with a high touch time. Masten has demonstrated a cost reduction of 60% in past injector builds.

Success of this SBIR project will be indicated by the construction and testing of two PermiAM RDE injectors. The three phases of this project are: design, manufacture, and testing. This SBIR will provide valuable information for several existing questions relating to RDE research. How to design a flight like liquid/liquid detonation engine, and how to design an injector capable of handling the extreme temperature and pressure environments.

Potential NASA Applications (Limit 1500 characters, approximately 150 words):

RDE’s have the inherent advantage of being theoretically more efficient than standard combustion engines. This is due to the detonation engine utilizing a Humphrey cycle over a Brayton cycle. A Humphrey cycle is a constant volume cycle, where a Brayton cycle is constant pressure.

Potential Non-NASA Applications (Limit 1500 characters, approximately 150 words):

In a perfect system and RDE has the potential to be about 15% more efficient than that of a constant pressure device. The ability to utilize this kind of increase would be invaluable in commercial application, where fuel consumption can be a major driver in cost.
