LHTEC T800

The LHTEC T800 is a turboshaft engine for rotary wing applications, produced by LHTEC (Light Helicopter Turbine Engine Company), a joint venture between Rolls-Royce and Honeywell, with CTS800 as the commercial and export version. It was developed for the United States Army LHX armed reconnaissance helicopter competition against the Avco/Pratt and Whitney T800 and was selected to power the LHX in 1988. It was primarily meant for the RAH-66 Comanche, and a pair of T800-powered prototypes flew between 1996 and 2004 before the programme was cancelled. The T800-LHT-801 has single-stage low-pressure and high-pressure centrifugal compressors and produces 1,563 shp (1,166 kW). Later applications include the AgustaWestland AW159 Wildcat and the TAI T129 ATAK.
