IV.C.01—Integrated High–Performance Turbine Engine Technology (IHPTET). IHPTET is a three–phased tri–Service/DARPA/NASA effort to double U.S. turbine engine performance capability by 2003. Develop a tri–Service Joint Turbine Advanced Gas Generator (JTAGG) program to demonstrate performance goals consistent with the IHPTET initiative for the turboshaft/turboprop class of engines. Demonstrate, by FY94, a 25 percent reduction in specific fuel consumption (SFC) and 60 percent increase in power–to–weight ratio over current modern production engines via Joint Turbine Advanced Gas Generator—I (JTAGG–1) demonstration. By FY98, demonstrate JTAGG II improvements of 30 percent reduction in SFC and 80 percent increase in power–to–weight ratio, and 20 percent reduction in production and maintenance costs. Develop for future demonstration gas turbine engine technology to effectively double the propulsion system capability for turboshaft engines through a 40 percent reduction of SFC, 120 percent increase in power–to–weight ratio, and 35 percent reduction in production and maintenance costs. Demonstrate emerging technologies related to IHPTET goals in areas of structures, controls, aerodynamics, advanced materials, and accessories which provide reduced vulnerability, improved reliability and maintainability, and high levels of readiness and mission success.

Supports: Precision Strike, Advanced Land Combat, Technology for Affordability, RAH–66 Comanche, AH–64 Apache Improvement, Joint Transport Rotorcraft (JTR), and system upgrades, AM, MS, EELS, D&SA, MBS, and CSS Battle Labs. Dual use potential.

IV.C.05—Integrated High–Performance Turbine Engine Technology (IHPTET) Joint Turbine.  Program Description: IHPTET is a three–phased tri–Service/DARPA/NASA effort to double U.S. turbine engine performance capability by 2003. Develop a tri–Service Joint Turbine Advanced Gas Generator (JTAGG) to demonstrate performance goals consistent with the IHPTET initiative for the turboshaft/turboprop class of engines. Initiate the third phase of the JTAGG program. By FY00 complete testing of JTAGG III technologies. By FY03 effectively double the propulsion system capability through demonstration of a 40% reduction in specific fuel consumption, a 120% increase in SHP/wt ratio, and a 35% reduction in production & maintenance costs. Demonstrate emerging technologies related to IHPTET goals in the areas of structures, controls, aerodynamics, advanced materials and accessories which provide reduced vulnerability, improved reliability and maintainability, and high levels of readiness and mission success.

Supports: Precision Strike, Advanced Land Combat, Technology for Affordability, RAH–66 Comanche; AH–64 Apache improvement, JTR, and system upgrades, AM, MS, EELS, D&SA, MBS, and CSS Battle Labs. Dual–use potential.
