The T700/CT7 Engine Family

The T700 Family

Turboshaft/Turboprop Power

The T700/CT7 engine family is the most widely used in its class--powering 21 types of rotary and fixed-wing aircraft for close to 130 customers in 55 countries.

  

Engine Overview

The T700/CT7 baseline engine was designed for the U.S. Army's UH-60A Black Hawk as a result of lessons learned from helicopter operations in Vietnam.

Ruggedness, safety and the ability to operate reliably under adverse environmental conditions while requiring minimal maintenance were key requirements. The Army also chose two later versions, the -701 and -701C, for its advanced attack helicopter, the AH-64 Apache and for the UH-60L Black Hawk.

A civil version of the baseline engine, the CT7-2, powered the Bell 214ST and the Sikorsky S-70, a Black Hawk derivative.

The T700/CT7 engines represent a quantum leap in reliability and maintainability over other engines in their class. Since its introduction in 1978, the T700/CT7 engine family has been proven in battle, in extreme environments, and in demanding passenger revenue service, amassing more than 50 million engine flight hours.

Today, the new and more powerful models of the T700/CT7 family - the CT7-8 and T700/T6E - build on an already exceptional level experience, applying the latest in technology to the proven durable, maintainable design.
