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. 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. [2] .

The T700 is a superior, proven design with advanced technological updates. The engine is an advanced, powerful, fully modular, and affordable turboshaft engine ready for a diverse portfolio of rotorcraft and fixed-wing applications. The T700 delivers 2,000 shp with exceptional reliability.

The T700 engine evolved directly from Army experience in the Vietnam War's difficult operating conditions that created helicopter engine maintenance problems. GE won the 1971 power plant competition for the proposed Utility Tactical Transport System (UTTAS) helicopter, with specifications for a high performance, low fuel consumption, reduced ...

Designed to be rugged, reliable and easily maintainable, current T700 models apply advanced technology to an experience base of more than 50 million hours of operation. The -701D powers both the newest Sikorsky UH-60M Black Hawk and Boeing AH-64E helicopters.

2004年11月4日 · Rated at 2,000 shaft horsepower (shp), the T700-GE-701D features improved hot-section components that provide twice the hot-section durability and 5 percent more power than the current T700-GE-701C model engine.

2004年2月24日 · The T700-GE-401C that powers the UH-1Y is a newer, more capable version of the T700-GE-401, offering eight percent more power. The T700-GE-401C is under consideration to power the AH-1Z in addition to the UH-1Y. Both engines serve to increase the AH-1Z and UH-1Y payload and range capabilities.

2004年7月19日 · The T700 engine and its civil counterpart, the CT7, have amassed more than 50 million flight-hours powering 21 different aircraft models in service throughout the world, and T700-powered aircraft accounted for nearly 70 percent of …

2024年10月17日 · The T700 has a 5-stage axial-flow, 1-stage centrifugal-flow compressor, with a 2-stage axial-flow gas producer and 2-stage axial-flow power turbine. The T700 is 3 feet, 11 inches (1.194 meters) long, 2 feet, 1 inch (0.635 meters) in …

The T700-GE-700 is rated at 1,622 shp (1,210 kW) intermediate power. The T700-GE-700 was followed by improved and uprated Army engine variants for the UH-60 Black Hawk and the AH-64 Apache helicopters, as well as marinized naval engine variants for the SH-60 Seahawk derivative of the Black Hawk, the SH-2G Seasprite, and the Bell AH-1W Supercobra.

The T700 military turboshafts have earned a reputation for exceptional performance in combat and under the worst environmental conditions. Designed to be rugged, reliable and easily maintainable, current T700 models apply advanced technology to an experience base of 50 million hours of operation.
