Recent IHPTET successes are providing technologies that allow critical modernization of the F100, F110, and F404 families of engines--the backbone of Air Force frontline aircraft.
The performance improvements demonstrated in IHPTET efforts are also being traded to provide increased component lives or cost reductions in fielded systems.
Each IHPTET participant manages its own resources, which are not pooled (in contrast to some joint government/industry initiatives).
Nearly 75 percent of what the IHPTET participants develop is transferable to the civilian sector, the major exceptions being stealth technology, afterburning technology, and air-breathing missile engine technology.
Four major IHPTET technologies are being jointly pursued by the Air Force at Wright-Patterson Air Force Base in Dayton, Ohio, and the Navy at Patuxent River, Md.
The first swept rotor was tested in 1986, and because of its success, swept aerodynamics was incorporated into the IHPTET program.
Swept rotors have been tested in demonstrator engines for all IHPTET engine classes.

Mayhew and her IHPTET colleagues developed brush seals, so called because the bristles cover the circumference of the seal like a brush whose wire bristles are compliant.
Reversing the typical path of IHPTET projects, brush seals entered commercial aviation before they were used for military applications because of the less rigorous conditions of civilian aircraft.
IHPTET engineers continue to extend the performance of brush seals.
