SIMPLE DESIGN DRIVES EFFICIENCY
The next-generation CTS800 turboshaft family of engines was developed by the Light Helicopter Turbine Engine Company (LHTEC), a 50:50 partnership between Rolls-Royce and Honeywell. It has the highest power-to-weight ratio and lowest specific fuel consumption (SFC) in its class. Weighing in at only 375 pounds, it allows for a max takeoff weight of over 11,000 pounds.
The CTS800 engine features a modular design with dual shafts, two-stage centrifugal compressor, annular combustor, two-stage high pressure (HP) and two-stage power turbine. All models are equipped with an inlet particle separator module. Many applications require the incorporation of an output speed reduction gearbox (RGB). All models are controlled by an advanced, highly-redundant, dual channel full authority digital engine control (FADEC) system.
And with 100% FADEC control and on-condition maintenance, the CTS800 reduces pilot workload and improves the overall cost of ownership. It is also FAA certified and EASA validated and is in service with armed forces around the world.
The highly reliable and maintainable CTS800 principal engine design was originally developed to power the U.S. Army's Boeing Sikorsky RAH-66 Comanche helicopter.
