ONE YEAR ESTROGEN/PROGESTIN IMPLANT

Not Available The importance of a low-drag, efficient fuel injection systemfor scramjet combusion cannot be overstated. Fuel injection and mixing have been identified by the Air Force Hypersonic Technology Office as significant technological challneges, which must be addressed as a prerequisite for succeccful scramjet operation. To this end, the primary ofjective of the proposed research program is to provide the engine designer with scramjet fuel injectors that achieve better penetration, lower performance losses, and higher mixing efficiencies than previously tested fuel injections. This will be accomplished through the use of narrow, flush-mounted, locally pressure-matched injectors that would produce little drafg, require no active colling,and produce only a small region of high heat flux on the combustor wall. The military and private-sector markets for a dramatically improved scarmjet injector are substantial, and the development of such an injector would greatly strenghten the position of the developing organization within the niche area of hypersonic propulsion. Indeed, such an achievement would allow a small business to pursue strategic alliance with major propulsion system developers and integrators, placing revolutionary scramjet technology in the hands of organizations with the potential for successful application of that technology and giving the small business an opportunity to broaden its involvement in the aerospace industry.
