CHIMERIC YF/DEN2 AS A VACCINE CANDIDATE FOR DENGUE VIRUS

Not Available MSE Technology Applications, Inc. (MSE), with United Technologies Research Center and HyperTech Concepts Company proposes to develop combine propulsion for a small reusable launch vehicle (RLV), known as the KLINtm Cycle, consisting of a thermally integrated deeply cooled turbojet and liquid rocket engine. The objective of this approach is to achieve a high pressure ratio in a simple, lightweight turbojet engine. The result is an exceptional engine thrust-to-weight ratio and improved specific impulse and mass fraction of the launcher. For a heavy launcher, the KLINtm Cycle promises RLV gross takeoff weight (GTOW) reduction by a factor of two with prospects of lower dry weight. If based on the FL-10 engine family, the KLINtm Cycle makes a small single-stage-to-orbit and two-stage-to-orbit RLV feasible and economically very attractive. Specific objectives of the initial portion of the study are to demonstrate: 1) the performance and mass of a KLINtm Cycle based on an existing rocket engine of the RL-10 family applied to a small RLV; 2) the advantages of integrating a KLINtm Cycle into a small RLV (50-100 ton of GTOW); 3) the core technology development program. The benefit to the Air Force is low life-cycle cost combined propulsion for a space plan which can double existing rocket propulsion capabilities by the year 2010.
