GE38-1B


Program Status: Under Development
IOC: 2015
Origin: United States of America

Contractor/s: General Electric Aviation

Description: The General Electric GE38-1B is a turboshaft engine is based on the GE27 technology demonstrator and the US Navy's T407 turboprop engine. GE27 served as the basis for the CFE738 commercial turbofan engine which powers the Dassault Falcon 2000 jet. Developing more than 7,500-shp at sea level the new engine is provided with a similar architecture to the popular T700 engine. General Electric's main goals for the GE38-1B are: significant advances in engine performance, fuel efficiency and low life-cycle cost.

The GE38-1B has a five-stage axial compressor coupled with a single-stage centrifugal compressor. It has a low-emission, annular combustor, two-stage gas generator turbine, and three-stage power turbine. It features a dual-channel Full Authority Digital Electronic Control (FADEC) system with advanced health monitoring functions. The engine is highly resistant to sand erosion, salt-water corrosion and offers stall-free operation in all conditions - features ideal to withstand the Marine Corps' tough operating environments.

To date, the GE38-1B engine has been selected to power the US Marine Corps' CH-53K helicopter being developed by Sikorsky. CH-53Ks will supersede CH-53E helicopters which are powered by T64 engines. The GE38-1B features 60 percent fewer parts with longer component lives than its T64 predecessor. In addition, the new engine will offer excess power to meet current and future CH-53K mission requirements.
