The Allison Model 250, now known as the Rolls-Royce M250, is a highly successful turboshaft engine family, originally developed by the Allison Engine Company in the early 1960s. The Model 250 has been produced by Rolls-Royce since it acquired Allison in 1995.
The Progress D-27 is a three-shaft propfan engine developed by Ivchenko Progress. The gas generator was designed using experience from the Lotarev D-36 turbofan. The D-27 engine was designed to power more-efficient passenger aircraft such as the abandoned Yakovlev Yak-46 project, and it was chosen for the Antonov An-70 military transport aircraft. As of 2019, the D-27 is the only contra-rotating propfan engine to enter service.
The WZ-9 is a turboshaft engine developed in the People's Republic of China for use in the CAIC Z-10 attack helicopter.
The Turbomeca Artouste is an early French turboshaft engine, first run in 1947. Originally conceived as an auxiliary power unit (APU), it was soon adapted to aircraft propulsion, and found a niche as a powerplant for turboshaft-driven helicopters in the 1950s. Artoustes were licence-built by Bristol Siddeley in the UK, Hindustan Aeronautics Limited in India, and developed by Continental CAE in the US as the Continental T51. Two major versions of the Artouste were produced. The Artouste II family, mainly used in the Aérospatiale Alouette II helicopter, had a one-stage centrifugal compressor and a two-stage turbine, with gearbox-limited power of 300 kW (400 hp). The Artouste III family, mainly used in Aérospatiale's Alouette III and Lama helicopters, had a two-stage axial-centrifugal compressor and a three-stage turbine, with gearbox-limited power of 420–440 kW (560–590 hp).
The Honeywell T55 is a turboshaft engine used on American helicopters and fixed-wing aircraft since the 1950s, and in unlimited hydroplanes since the 1980s. Today, there have been more than 6,000 of these engines built. It is produced by Honeywell Aerospace, a division of Honeywell based in Phoenix, Arizona, and was originally designed by the Turbine Engine Division of Lycoming Engines in Stratford, Connecticut, as a scaled-up version of the smaller Lycoming T53. Both engines are now produced by Honeywell Aerospace, and the T55 serves as the engine on several major applications including the CH-47-Chinook, the Bell 309, and the Piper PA-48 Enforcer. The T55 also serves as the core of the Lycoming ALF 502 turbofan. Since the T55 was first developed, progressive increases in airflow, overall pressure ratio, and turbine inlet temperature have more than tripled the power output of the engine.
The Solar T62 Titan is an American gas turbine engine used mainly as a helicopter auxiliary power unit (APU), ground power generator or helicopter powerplant. A free power turbine version was developed as the Solar T66.
The Klimov VK-800 is a turboshaft engine of the fifth generation. It is designed to equip the Mi-54, Ansat and Ka-226 "Sergei" type helicopters. The VK-800V derivative was developed for the power units of helicopters of small and large load-carrying capacity, both in twin- and single-engine configuration. The engine parameters meet the requirements of the tested model of a centrifugal compressor and the single-stage un-cooled turbines. All this simplifies the engine design and reduces expenses for its manufacture and operation. Moreover, the enhanced characteristics of the main units of the engine provide its high efficiency.
The Klimov VK-2500 is a Russian turboshaft aero engine, a high power derivative of the TV3-117VMA engine, also for hot and high.
JSC Russian Helicopters is a helicopter design and manufacturing company headquartered in Moscow, Russia. The company designs and manufactures civilian and military helicopters. The company's principal shareholder is Rostec. It is the world's 24th-largest defence contractor measured by 2012 defence revenues, and the second-largest based in Russia.
The Ivchenko AI-24 turboprop aircraft engine was designed and developed in the late-1950s by the Ivchenko design bureau and manufactured thereafter by Motor Sich. It was designed to power Antonov's successful An-24, An-26 and An-30 aircraft series.
The Safran Arrano is a turboshaft engine for two-to-three ton single-engine and four-to-six ton twin-engine helicopters, developed by Safran Helicopter Engines, outputting 1,100 to 1,300 hp.
The MAN Turbo 6022 is a German gas turbine turboshaft engine for helicopter use. Designed in the early 1960s by BMW the engine powered the third prototype of the MBB Bo 105 on its maiden flight in December 1967.
The Advanced Heavy Lifter is a large helicopter project developed by Aviation Industry Corporation of China.
The Saturn/Lyulka AL-34 was an unbuilt turboshaft/turboprop engine for rotary and fixed-wing aircraft, proposed by the Soviet Union in the early 1990s. In turboprop form, the engine was offered for light aircraft such as the Sukhoi Su-86 eight-passenger business airplane, the Myasishchev M-101T Gzhel business jet, the ROS-Aeroprogress T-101 Grach nine-passenger aircraft, its derivative T-108 Zolotoy Orel nineteen-passenger aircraft, and the Krunichev T-511 "AIST-M". As a turboshaft, the AL-34 was proposed to power the Mil Mi-54 and the Kazan Ansat helicopters. The engine was also considered for unconventional aircraft such as the Mil Mi-30L Vintoplan tiltrotor aircraft, and it was to be an auxiliary engine for powering the boundary layer control system and air cushion on the EKIP flying saucer.
The TAI T929 ATAK 2 is a twin-engine, heavy attack helicopter under development by Turkish Aerospace Industries. The helicopter is designed for attack, electronic warfare and reconnaissance missions in all-weather environments in both day and night conditions.
The Lotarev D-136 is a turboshaft engine from the ZMKB Progress Design Bureau. The engine powers the Mil Mi-26 "Halo" helicopter. Development of the engine had begun in about 1972.. The D-136 first flew on a production Mi-26 helicopter in 1980.
