The Pratt & Whitney Canada PW200 is a family of turboshaft engines developed specifically for helicopter applications. It entered service in the 1990s.
The Rolls-Royce Turbomeca RTM322 is a turboshaft engine produced by Safran Helicopter Engines. It was originally conceived and manufactured by Rolls-Royce Turbomeca Limited, a joint venture between Rolls-Royce plc and Turbomeca. The engine was designed to suit a wide range of military and commercial helicopter designs. The RTM322 can also be employed in maritime and industrial applications.
The Pratt & Whitney Canada PT6 is a turboprop aircraft engine produced by Pratt & Whitney Canada. Its design was started in 1958, it first ran in February 1960, first flew on 30 May 1961, entered service in 1964, and has been continuously updated since. The PT6 consists of two basic sections: a gas generator with accessory gearbox, and a free-power turbine with reduction gearbox. In aircraft, the engine is often mounted "backwards," with the intake at the rear and the exhaust at the front, so that the turbine is directly connected to the propeller. Many variants of the PT6 have been produced, not only as turboprops but also as turboshaft engines for helicopters, land vehicles, hovercraft, and boats; as auxiliary power units; and for industrial uses. By November 2015, 51,000 had been produced, which had logged 400 million flight hours from 1963 to 2016. It is known for its reliability, with an in-flight shutdown rate of 1 per 651,126 hours in 2016. The PT6A turboprop engine covers the power range between 580 and 1,940 shp, while the PT6B/C are turboshaft variants for helicopters.
The LHTEC T800 is a turboshaft engine for rotary wing applications. It is produced by the LHTEC, a joint venture between Rolls-Royce and Honeywell. The commercial and export version is the CTS800. The engine was primarily developed for the United States Army's cancelled RAH-66 Comanche armed reconnaissance helicopter, but has found use in other applications.
The MTU Turbomeca Rolls-Royce MTR390 is a turboshaft developed for light helicopter applications by MTU Turbomeca Rolls-Royce (MTR). The engine is designed to power helicopters in the weight range of 5-7 tonnes in both single and twin engine configurations. So far the only application is the Eurocopter Tiger. Test runs of the MTR390 began in 1989 and the first test flight was performed in 1991. The MTR390 received military certification in May 1996 and civil approval in June 1997.
The PZL SW-4 Puszczyk is a Polish light single-engine multipurpose helicopter manufactured by PZL-Świdnik. Following a protracted development, the SW-4 entered service in 2002, the primary operator of the type has been the Polish Armed Forces. The SW-4 was further developed by PZL-Świdnik and corporate parent AgustaWestland into an optionally piloted vehicle, the SW-4 Solo. From 2016 onwards, the type has been marketed to civil operators as the AW009, while the SW-4 designation is used for the military market.
The Airbus Helicopters H135 is a twin-engine civil light utility helicopter produced by Airbus Helicopters, formerly known as Eurocopter. It is capable of flight under instrument flight rules (IFR) and is outfitted with a digital automatic flight control system (AFCS). First flying in February 1994, it entered service in 1996. 1,400 have been delivered up to September 2020, to 300 operators in 60 countries, accumulating over 5 million flight hours. It is mainly used for air medical transport (medevac), corporate transport, law enforcement, offshore wind support, and military flight training. Half of them are in Europe and a quarter in North America. The H135M, certified under the name Eurocopter EC635, is a military variant, so the overall design is known as the Airbus Helicopters H135 and the military version, as the Airbus Helicopters H135M. The EC135/H135 is a development of the older Messerschmitt-Bölkow-Blohm (MBB) Bo 105.
The Rolls-Royce Gnome is a British turboshaft engine originally developed by the de Havilland Engine Company as a licence-built General Electric T58, an American mid-1950s design. The Gnome came to Rolls-Royce after their takeover of Bristol Siddeley in 1968, Bristol having absorbed de Havilland Engines Limited in 1961.
The Rolls-Royce Gem is a turboshaft engine developed specifically for the Westland Lynx helicopter in the 1970s. The design started off at de Havilland Engine division and passed to Bristol Siddeley as the BS.360. Rolls-Royce bought out Bristol Siddeley in 1966 and after it dropped the Bristol Siddeley identity the engine became the RS.360.
The MD Helicopters MD Explorer is a light twin-engined utility helicopter designed and initially produced by the American rotorcraft specialist McDonnell Douglas Helicopter Systems.
The General Electric T700 and CT7 are a family of turboshaft and turboprop engines in the 1,500–3,000 shp (1,100–2,200 kW) class.
The Turbomeca Astazou is a highly successful series of turboprop and turboshaft engines, first run in 1957. The original version weighed 110 kg (243 lb) and developed 240 kW (320 shp) at 40,000 rpm. It was admitted for aviation service on May 29, 1961, after a 150-hour test run. The main developing engineer was G. Sporer. It was named after two summits of the Pyrenees.
The Turbomeca Arriel is a series of French turboshaft engines that first ran in 1974. Delivering 650 to 1,000 hp, over 12,000 Arriel engines have been produced from 1978 to 2018, logging more than 50 million flight hours for 40 helicopter applications. In June 2018, 1,000 Arriel 2D were in service, powering H125 and H130 single-engine helicopters, having logged one million flight hours since 2011. After endurance tests and fleet data analysis, their TBO increased by 25% to 5,000 hours and mandatory inspection rose to 15 years with no hourly limit, lowering maintenance costs.
The Turbomeca Arrius is one of a family of turboshaft engines for helicopter use, first produced in 1981. As of 2012, some 2,700 units had been sold. Power ranges between 357 kW and 530 kW for different versions. Following Turbomeca tradition, the Arrius was named after a Pyrenean peak, located in the Ossau Valley near Pau.
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).
