When Turkish Aerospace Industries (TAI) and AgustaWestland joined forces to develop and build a new multi-mission helicopter for the Turkish Land Forces, they knew they would need engines that could handle the harshest “hot and high” temperatures and altitudes the rugged Turkish landscape could present.
They found the right engines for the job at the Light Helicopter Turbine Engine Company (LHTEC), a 50-50 partnership between Honeywell and Rolls-Royce. Each TAI T129 ATAK helicopter is powered by two LHTEC CTS800-4A turboshaft engines, the latest version of the engine originally designed for the U.S. Army Comanche helicopter program.
The CTS800-4A provides the rugged, durable performance the T129 needs to accomplish its attack, armed reconnaissance, armed escort, precision strike, fire support and other missions. The aircraft also needed to have a 24-hour a day global operational capability. Other requirements were all-environment operations with a low logistics footprint, mission effectiveness with high reliability, availability and maintainability.
Featuring high power-to-weight ratio, low fuel consumption, long engine life and economical maintenance periods, the CTS800-4A enables TAI to build aircraft that meet all the criteria demanded by the Turkish forces. The engine has successfully completed hot and high performance tests up to 15,000 feet and is certified for operation up to 20,000 feet.
The CTS800-4A features a Full Authority Digital Engine Control (FADEC) system for low maintenance, high reliability, excellent economy and reduced pilot workload. The CTS800-4A FADEC system includes an integrated engine monitoring system (EMS) to provide a high level of system safety and maintainability.
Engines in the CTS800 family have demonstrated their performance, reliability, fuel-efficiency and maintainability during more than 100,000 in-service flight hours under extremely demanding operating conditions. CTS800 engines power several versions of AgustaWestland Lynx helicopters including the AW159 Wildcat, the Japanese ShinMaywa US-2 amphibious aircraft and other utility, scout and attack platforms. A CTS800 engine also powers the Sikorsky X-2 Technology Demonstrator, which set an unofficial world helicopter speed record and received the 2010 Robert J. Collier Trophy for achievement in aeronautics and astronautics.
