GE38
The GE38 is a turboshaft engine for various helicopter and turboprop applications, such as Sikorsky Aircraft Corporation's heavy-lift helicopter CH-53K. The GE38 engine is based on the GE27 technology demonstrator engine completed for the U.S. military and the T407 turboprop engine developed for the U.S. Navy.
The GE38 is produced jointly by General Electric (GE) and MTU. In a first for the company, MTU also has a development role for a module under a U.S. military engine program. The company is responsible for the development and manufacture of the power turbine and will obtain licenses for maintenance, final assembly and testing of the GE38 models to power a future European heavy-lift helicopter (FTH = Future Transport Helicopter).
The German engine maker has a program stake of 18 percent.
