Vaporcor has been developing an engine technology that enables a means to implement a Humphrey thermodynamic cycle. In this SBIR, we propose an innovative technical concept and an aggressive business development plan that will take advantage of Vaporcor s unique engine technology and exploit Vaporcor s existing strategic partnership for the development of a technology base that will enable very high altitude aircraft (VHALE) and will advance HALE platforms. In Phase I, we propose to not only to perform the expected feasibility study for a very high altitude (~90 kft) aircraft propulsion engine capable of meeting the stability, reliability, and environmental requirements suitable for use on an VHALE aircraft with 12-20 hour endurance that must be stored for months, we propose to build a prototype engine and perform feasibility demonstrations of this engine s capability within the schedule of Phase I. If this engine proves acceptable to DARPA, in Phase II we will build a flight article of this engine in conjunction with our partnering VHALE company.
