- Summary
- The GE TG-100 (military designation T31) was the outgrowth of a National Advisory Committee for Aeronautics project initiated in 1941 by General Henry H. Arnold, Chief of the Army Air Corps. Designed at the Steam Turbine Division in Schenectady, N.Y., it was first ground tested in 1943 without a propeller.
- In late-1945, the TG-100, in a Consolidated Vultee XP-81, became the first turboprop to be flown in the U.S., and made more than 100 flights in the XP-81 and Ryan XF2R-1. Although originally designed for 895 kw (1,200 shp), the TG-100 delivered 1,268 kw (1,700 shp) in early tests, and was later rated at 1,641 kw (2,200 shp). In 1949, the TG-100 project was canceled as a result of increased interest in the development of jet engines.
- The TG-100 was the first GE aircraft engine to use an axial-flow compressor. Knowledge gained from it contributed to the development of the GE axial-flow turbine engines that followed.
