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 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.

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 maintenance, and combat damage resistant engine. This is one of the experimental engines used in the UTTAS rotorcraft competition in 1974.

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.

Jan 22, 2025 · When is a T700 engine refurbished? The quick answer is when the T700 maintenance exceeds either the authorizations or the abilities of the maintenance team. A short list of the most common problems is: Oil leaks or consumption exceeding OEM (or other authority) limits. Time Between Overhaul (TBO) items require replacement

Jan 22, 2025 · Through our series of articles, we will look at the development of the turbine engine, discuss its key modules, identify key steps to refurbishing the T700-GE-700 and address replacing the 700 with a 701C/D in a Black Hawk.

General Electric is developing the T700-GE-700 turboshaft engine for the U. S. Army Utility. Tactical Transport Aircraft System (UTTAS). The T700 is designed to operate in combat with improved. reliability, easy maintenance, low fuel consumption, and extended operating life. The T700 will operate with no visible smoke and at low noise levels.

The YT706 engine is based on the CT7-8A engine. Compared with the H-60's primary T700 engine, the T706 has a larger compressor, hot section improvements, and full authority digital engine control. [4]

Jul 19, 2004 · This year, GE is introducing into production the T700-701D engine, rated at 2000 shaft horsepower (shp), to power Sikorsky's next-generation UH-60M Black Hawk helicopter. The T700-701D is currently powering flight-test UH-60M aircraft at …

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 . The -701C powers the Sikorsky H -60 Black Hawk and
