The T900 dual-spool engine being developed by the Advanced Turbine Engine Company (ATEC) will generate 10% power growth capability than comparable single-spool offerings while weighing less and using 25% less fuel than current powerplants.
This additional power will allow for greater payloads and more operational flexibility for planners, pilots, and commanders. Dual-spool means an engine has two rotating turbine-compressor assemblies instead of just one. The use of two spools delivers better dependability, greater fuel efficiency, more power to grow and lower cost over the life of the engine compared to single-spool designs currently in use.
ATEC is a joint venture of Honeywell and Pratt & Whitney.
