Open Call for Innovative Defense-Related Dual-Purpose Technologies/Solutions with a Clear Air Force Stakeholder Need

Although the development of hypersonic technology presents the potential to revolutionize the aerospace industry, there are many challenges to successful implementation. Most notably, turbojet engines have difficulties operating at the speeds necessary for hypersonic flight as the high travel velocity results in high air temperatures that far exceed material temperature limits. As such, we propose a hypersonic engine that can be optimized for defense, commercial, and space use, capable of creating 50,000 lbf at sea level, and on the order of at least 10,000 lbf at 90,000 feet. Under our Phase I effort, we will conduct a feasibility study to assess current size estimates based on required thrust to achieve hypersonic speeds. We will also analyze multiple different cycle types to determine specific cycle characteristics that would allow for engine use across multiple sectors. By doing so, we will set the foundation for the Phase II effort by determining the optimal path towards successful development. In the Air Force alone, hypersonic flight would revolutionize fighter aircraft and rapid deployment capabilities. But beyond the Air Force, our proposed solution will also have major implications for the DoD, commercial aviation industry, and space exploration.
