Integrated High Performance Turbine Engine Technology (IHPTET) program,
started in 1988, has an aggressive technology development plan to leapfrog
technical barriers and deliver twice the propulsion capability of today's
systems by 2005. Unprecedented teaming of the Army, Navy, Air Force, NASA,
DARPA and industry, in each of the engine component technolgy areas, is
underway. The main focus of these "Technology Teams in Action" is to advance
military aircraft superiority through high performance, affordable, robust
IHPTET's aggressive three phase plan maximizes technology transition to both military and commerial users, and defines interim technolgy goals against which progress is measured. IHPTET is producing revolutionary advancements in turbine engine technologies due to the synergistic effect of combining advanced material developments, innovative structural designs and improved aerothermodynamics. Phase I goals have been demonstrated and provide a 30% increase in propulsion capability. Many technologies resulting from Phase I have been directly transfered to engines such as the F100 & F110 Increased Performance Engines (F-15, F-16), F414 engine (F-18 E/F) and the F119 engine (F-22). Phase II is nearly complete and will provide a 60% increase in propulsion capability which will permit the introduction of concepts such as supersonic STOVL fighters (as in the Joint Strike Fighter (JSF)), V/STOL transports, innovative rotorcraft, and unique tactical missiles. The Phase III goal of 100% increase in propulsion capability will enable specific system payoffs such as: sustained Mach 3+ in an F-15 sized aircraft, greater range/payload in an F-18 sized STOVL aircraft, a 100% range/ payload increase in a CH-47 sized helicopter and intercontinental range in an Air Launched Cruise Missile (ALCM) sized missile. In addition, achieving the IHPTET goals will ensure continued US preeminence in the increasingly competitive international marketplace.
IHPTET provides numerous benefits beyond performance improvement. The development of new materials and advanced structural designs will make engine systems more robust due to stronger and more durable components. State-of-the-art design practices will lead to longer inspection intervals for parts, which will lower maintenance costs. IHPTET also provides the basis for continued preeminence in civil aircraft engines, as the technology is almost entirely dual-use in nature.
