Powering the UH-60 are two General Electric T700-GE-701C turboshaft engines. The T700 is one of the most successful turboshaft engines ever built. With these powerful engines, a Black Hawk’s capabilities include carrying two pilots, two crew chiefs, along with eleven troops or six stretchers. It can carry 9,000 lb. of external cargo. See video of the Black Hawks airlifting artillery guns to the field.
The T700 is very reliable and easy to maintain. This engine has been successful in battle, extreme environments, and commercial services. The GE turboshaft has successfully powered 25 types of civilian and military helicopters, like the UH-60 Black Hawk, the AH-64 Apache, the Marine Corps MH-60 Seahawk, and the U.S. Air Force HH-60 Pave Hawk. The T700 even powers some fixed-wing civil and military aircraft.
For continuous monitoring of its performance, the General Electric T700 is connected to a Supervisory Turbine Engine Control Unit (p/n 5078T29G02 NSN 2995-01-367-7628). This electronic control unit provides performance monitoring of engine speed, engine temperature, airflow, as also adjusts the fuel control to compensate for changes. It may also have the capability of load sharing, rotor speed governing, loss-of-load protection, and analog or manual backup modes.
