Engine thrust-to-weights projected for the year 2000 and beyond will provide the technology for light weight compact propulsion systems for supersonic STOVL. Higher turbine inlet and compressor discharge temperatures made possible by material improvements will be the enabling technologies that will increase thrust per pound of air. High specific thrust engines will reduce engine size which is important to installation in supersonic aircraft. The projected improvements in high strength/density materials will reduce engine weight to facilitate attainment of the high thrust-to-weight goals. Vertical landing aircraft are more sensitive to engine weight than CTOL aircraft, so that light weight engines will have a greater impact. The impact of advanced engine technology on Supersonic STOVL aircraft was predicted for a representative STOVL engine system. Current advanced technology engines provided the basis for the technology comparison. The Remote Augmentor Lift Systems (RALS) was used as one of the several contending STOVL engine concepts to show the technology impact. The capability of the near term technology, low bypass, high fan pressure ratio engines to provide high dry specific thrust was utilized in a STOL concept that accomplished the intent of the STOVL mission. The concept has been designated as SLIDE for Short Landing Integrated Deflected Exhaust. In the SLIDE concept the aircraft and engine share in a minimum of modification to achieve a short landing roll. A takeoff gross weight comparison of the SLIDE and STOVL aircraft is made to quantify the vertical versus short landing capability.
