General Electric T700
The General Electric T700 and CT7 are a family of turboshaft and turboprop engines in the class. Design and development In 1967, General Electric began work on a new turboshaft engine demonstrator designated the "GE12" in response to US Army interest in a next-generation utility helicopter. The GE12 was designed and conceived by GE's Art Adamson and Art Adinolfi. In 1967, both GE and Pratt & Whitney were awarded contracts to work parallel with each other to design, fabricate, and test the technology. The Army effort led, in the 1970s, to development of the Sikorsky S-70 Black Hawk, powered by twin GE "T700" turboshafts, the production descendant of the GE12. The T700 was initially bench-tested in 1973, passed military qualification in 1976, and went into production in 1978. The initial "T700-GE-700" is an ungeared free-turbine turboshaft, with a five-stage axial / one-stage centrifugal mixed-flow compressor, featuring one-piece "blisk" axial stages, with the inlet guide vanes ...

Sikorsky S-70
The Sikorsky S-70 is an American medium transport/utility helicopter family manufactured by Sikorsky Aircraft. It was developed for the United States Army in the 1970s, winning a competition to be designated the UH-60 Black Hawk and spawning a large family in U.S. military service. New and improved versions of the UH-60 have been developed since. Civilian versions, and some military versions, are produced under various S-70 model designations. Development The S-70 family was developed to meet a United States Army requirement to replace the UH-1 Iroquois family of utility medium-lift helicopters in 1972. Three YUH-60A prototypes were constructed, with the first flying in October 1974. They were evaluated against the Boeing-Vertol YUH-61A. The YUH-60A was selected for production, and entered service as the UH-60A Black Hawk with the U.S. Army in 1979. After entering service, the helicopter was modified for new missions and roles, including mine laying and medical evacuation. ...

Let L-610
The Let L-610 is a prototype aircraft for the Czech civil aircraft manufacturer Let Kunovice made in 1988–1997. Design and development In the late 1970s, after the success of the LET L-410 twin engine turboprop, the Soviet airline Aeroflot requested that LET design a replacement for the Antonov An-24 aircraft. LET's L-610 was designed as a twin engined turboprop aircraft powered by the new Czech engine, Walter M602, with a seating capacity of 40. Flight testing was delayed by engine development taking longer than airframe development. Eventually the 1,358 kW (1,822 shp) turboprop engines were finished and the aircraft first flew on 28 December 1988. No aircraft was ever delivered to any commercial customer, although one aircraft was shown in Aeroflot markings during the Paris Air Show in the 1990s. One Let 610 M was delivered to the Czech Air Force, to support manufacturer's certification and test flights process. After the Soviet collapse LET tried to westernize the p ...

Bell 214ST
The Bell 214ST is a medium-lift, twin-engine helicopter descended from Bell Helicopter's ubiquitous UH-1 Huey series. Though it shares a type number with the somewhat-related Bell 214, the 214ST is larger and of quite different appearance. Design and development The Bell 214ST was originally developed as a military project from the Bell 214B BigLifter, specifically for production in Iran and the development by Bell was funded by the Iranian government.Apostolo, Giorgio. ''The Illustrated Encyclopedia of Helicopters'', p. 54. New York: Bonanza Books, 1984. . The fundamental difference was the replacement of the Model 214's single Lycoming LTC-4 turboshaft engine with two General Electric T700 engines, to improve the helicopter's hot and high performance and improve safety. An interim twin-engine conversion of a Model 214 flew on 15 February 1977 in Texas,Green, William, ''Observers Aircraft'', p. 228.

AgustaWestland AW101
The AgustaWestland AW101 is a medium-lift helicopter in military and civil use. First flown in 1987, it was developed by a joint venture between Westland Helicopters in the United Kingdom and Agusta in Italy in response to national requirements for a modern naval utility helicopter. Several operators, including the armed forces of Britain, Denmark, and Portugal, use the name Merlin for their AW101 aircraft. It is manufactured at factories in Yeovil, England, and Vergiate, Italy. Licensed assembly work has also taken place in Japan and the United States. Prior to 2007, the aircraft had been marketed under the designation EH101. The original designation was EHI 01, from the name given to the Anglo-Italian joint venture—European Helicopter Industries—but a transcription error changed this to EH101. In 2000, Westland Helicopters and Agusta merged to form AgustaWestland, leading to the type's current designation. The AW101 entered into service in 1999 and has since replaced ...

AH-1 SuperCobra
The Bell AH-1 SuperCobra is a twin-engined attack helicopter that was developed on behalf of, and primarily operated by, the United States Marine Corps (USMC). The twin Cobra family, itself part of the larger Huey family, includes the AH-1J SeaCobra, the AH-1T Improved SeaCobra, and the AH-1W SuperCobra. The Super Cobra was derived from the single-engined AH-1 Cobra, which had been developed during the mid-1960s as an interim gunship for the U.S. Army. The USMC had quickly taken an interest in the type, but sought a twin-engined arrangement for greater operational safety at sea, along with more capable armaments. While initially opposed by the Department of Defense, who were keen to promote commonality across the services, in May 1968, an order for an initial 49 twin-engine AH-1J SeaCobras was issued to Bell. The type entered service during the final months of the US's involvement in the Vietnam War, seeing limited action in the theatre as a result. The USMC promptly sought ...
