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 Turbomeca TM 333 is a turboshaft engine manufactured by French company Turbomeca and designed for helicopters weighing 4-5 tonnes. It first ran in August 1981 and was introduced commercially in the mid-1980s. It was the first Turbomeca engine to use a single stage turbine, making it more compact than its predecessors. In its original design, the engine was rated at 750 continuous horsepower, though it was designed to allow for future power increases, and the later 2B2 variant made 1,100 horsepower.
The Napier Gazelle is a turboshaft helicopter engine that was manufactured by D. Napier & Son in the mid-1950s. In 1961 production was nominally transferred to a joint venture with Rolls-Royce called Napier Aero Engines Limited. But the venture closed two years later.
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 1966, Bristol having absorbed de Havilland Engines Limited in 1961.
The Bristol Siddeley Nimbus, later known as the Rolls-Royce Nimbus, was a British turboshaft engine developed under license by Blackburn Aircraft Ltd. from the Turbomeca Turmo in the late 1950s. It was used on the Westland Scout and Westland Wasp helicopters.
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 AgustaWestland AW149 is a medium-lift multi-role military helicopter developed by AgustaWestland, now Leonardo, launched in 2006 and had its first flight in 2009. By 2014 it had received military flight certification, and it went on to enter production going into military service with Egypt and Thailand. It is also planned for Poland with a new PZL-Swidnik production line there that opened in 2024, and North Macedonia has a pending order. The aircraft the only contender for the British NMH procurement program in the 2020s.
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 Turmo is a family of French turboshaft engines manufactured for helicopter use. Developed from the earlier Turbomeca Artouste, later versions delivered up to 1,300 kW (1,700 shp). A turboprop version was developed for use with the Bréguet 941 transport aircraft.
The Turbomeca Makila is a family of French turboshaft engines for helicopter use, first run in 1976 and flown in 1977.
The Westland 30 is a medium-sized civil helicopter designed and produced by the British aerospace company Westland Helicopters. It was derived from the Westland Lynx series of military helicopters, with which it retains a high level of commonality.
The Safran Ardiden is a 1,400–2,000 hp (1,000–1,500 kW) turboshaft designed and produced by Safran Helicopter Engines for 5–8 t (11,000–18,000 lb) single and twin-engine helicopters. Launched in 2003 as a more powerful TM 333, it first ran in 2005 and was introduced in 2007.
The AgustaWestland AW189 is a twin-engined, super-medium-lift helicopter manufactured by Leonardo S.p.A. It is derived from the AW149, and shares similarities with the AW139 and AW169.
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 Leonardo Next-Generation Civil Tiltrotor is a tiltrotor aircraft demonstrator designed and developed by the Italian aerospace company Leonardo S.p.A. Studies for a two times larger tiltrotor than the AgustaWestland AW609 started in 2000. Since 2014, its development is sponsored by the European Union's Clean Sky 2 program. By May 2021, major components were under production By 2023, the maiden flight had been pushed back to 2024, from a 2020 initial plan.
