The LHTEC CTS800 is a collaborative turboshaft engine between Rolls-Royce and Honeywell.
The CTS800 engine features modular design with dual shafts, two-stage centrifugal compressor, annular combustor, two-stage HP and two-stage power turbine. All models are equipped with an inlet particle separator module. Many applications require the incorporate of a speed reduction gearbox. All models are controlled by an advanced, highly redundant, dual channel FADEC (full authority digital engine control) system.
The next-generation CTS800 turboshaft family of engine was developed by the Light Helicopter Turbine Engine Company (LHTEC), a 50:50 partnership between Rolls-Royce and Honeywell. The highly reliable and maintainable CTS800 principal engine design was originally developed to power the US Army's Boeing Sikorsky RAH-66 Comanche helicopter. Production versions of the CTS800 family of engines produce 1,360 shaft horsepower in a basic engine configuration weighing less than 360 pounds (less than 410 pounds with the speed reduction gearbox installed).
The CTS800 engine has been installed in a large variety of aircraft applications throughout its development including flight test evaluations in the Eurocopter AS.365, Vought HH-65, Bell UH-1H and HAL ALH. The CTS800 has also been selected as the boundary layer compressor drive for the ShinMaywa US-2 amphibious search and rescue aircraft upgrade. A CTS800-powered version of the Agusta A129 attack helicopter first flew in 1988, this engine being offered for both new A129 sales and fleet upgrades.
The CTS800 also powers the next generation of AgustaWestland Super Lynx aircraft, having first flown in the Lynx in 1991. The CTS800-powered Super Lynx has already attracted four new operators, with the engine also being offered as an upgrade for existing Lynx fleets.
