Integrated High Performance Turbine Engine Technology
Encyclopedia
The Integrated High Performance Turbine Engine Technology program was a project of the United States military. Its objective was to conduct science and technology research that would secure advancements in the engineering of the gas turbine engines
used in military aircraft. It ran from 1987 until 2005.
IHPTET designated goals in each of three engine classes: turbofan
/turbojet, turboprop
/turboshaft
, and expendable engines. For the turbofan class the primary goal was to double the engine thrust-to-weight ratio
.
The program made many significant developments which have been employed in such aircraft as the F-35 / Joint Strike Fighter
. It was firmly regarded as successful although it did not fully achieve its explicit goals. It was succeeded by the Versatile Affordable Advanced Turbine Engines (VAATE) program.
Gas turbine
A gas turbine, also called a combustion turbine, is a type of internal combustion engine. It has an upstream rotating compressor coupled to a downstream turbine, and a combustion chamber in-between....

Turbofan
The turbofan is a type of airbreathing jet engine that is widely used for aircraft propulsion. A turbofan combines two types of engines, the turbo portion which is a conventional gas turbine engine, and the fan, a propeller-like ducted fan...
/turbojet, turboprop
Turboprop
A turboprop engine is a type of turbine engine which drives an aircraft propeller using a reduction gear.The gas turbine is designed specifically for this application, with almost all of its output being used to drive the propeller...

Turboshaft
A turboshaft engine is a form of gas turbine which is optimized to produce free turbine shaft power, rather than jet thrust...

Thrust-to-weight ratio
Thrust-to-weight ratio is a ratio of thrust to weight of a rocket, jet engine, propeller engine, or a vehicle propelled by such an engine. It is a dimensionless quantity and is an indicator of the performance of the engine or vehicle....
