RAH-66 Comanche Gets Twin Turbine Tune-Up
On June 1 Boeing and Sikorsky flew the first prototype RAH-66
Comanche attack helicopter with upgraded 1,563 shp T800-LHT-801
turbo-shaft engines. The 801 has 17% more power than the
original 800 engine, thus assuring the aircraft will meet
the milspec requirement for a 500 fpm climb rate and 165 KTAS
maximum cruise speed at a MTOW of at least 12,000 pounds in hot-and-high
conditions.
