GE Aviation's T901 Engine

摘要

GE Aviation's T901 turboshaft, one of two development engines competing for the US Army's Improved Turbine Engine Program (ITEP) requirement for a 3,000shp-class replacement for the GE T700s powering the Army's Sikorsky H-60 and Boeing AH-64 fleets, has the same number of modules as the T700 and is dimensionally identical. However, in other respects the T901 differs greatly from its predecessor, according to Ron Hutter, executive director of the T901 program for GE. While GE doesn't confirm the numbers of compressor and high-pressure turbine (HPT) stages in the T901 (the T700 has five axial and one centrifugal compressor stages and two HPT stages), Hutter told AIR International that in addition to being a single-spool design like the T700, the more powerful T901 also has four modules and is as highly modular as its predecessor.
