Honeywell HTS900

The HTS900 is an American turboshaft engine produced by Honeywell Aerospace as a growth version of the LTS101, which it is designed to replace, in the 1,000 shaft horsepower class. The version covered by the FAA data is a free-turbine turboshaft with a two-stage centrifugal compressor, a reverse-flow annular combustor and single-stage gas producer and power turbines, rated at 820 horsepower at takeoff and controlled by a dual-channel FADEC with an electromechanical backup. At the October 2018 NBAA convention it was shown with two 200 kilowatt electric generators for hybrid-electric aircraft, and it can be developed up to one megawatt. The applications named are the Bell ARH-70 Arapaho, the Kopter AW09 and the XTI TriFan 600.
