The Mars ascent vehicle (MAV) main engine is one potential opportunity, since the pressure drop penalty incurred by using this cooling approach is minimal. A low-cost, high-performance chamber made from relatively ordinary materials could easily replace the radiation-cooled, refractory/precious metal spacecraft engines. The next generation engine (NGE) will likely be an advanced expander cycle upper stage engine, and represents a NASA and Air Force opportunity for this technology. An expander cycle engine would benefit greatly from the reduced pressure drop, either by an increase in chamber pressure and thrust or in MCC and turbomachinery life. The Space Launch System (SLS) Program is another opportunity, particularly since the expendable boosters will be competed. PWR, our commercialization partner, is working to define booster concepts, and their engines, that would also benefit from a low-cost, high-performance regenerative cooling scheme. Since we have partnered with them on this technology, it presents an unusually good commercialization opportunity. We will also try to capitalize on the Air Force's interest in large booster engines, such as the recently-terminated 3GRB demonstration program. As Congress works to remove the threat of sequestration, we anticipate that the Air Force will return to previous levels of R&D investment, which may enable us to insert this technology into those future programs. NASA, Air Force and Army decision makers are all focused upon the development of a small, low-cost launch vehicle capable of carrying nanosatellites and microsatellites to orbit. A booster engine that featured a low pressure-drop cooling scheme like this one would offer higher performance than the ablative designs being considered.
