Allison has received a double boost with the civil certification of its Model 250-C30R/3 turboshaft for the US Army's Bell OH-58D Kiowa Warrior helicopter and the signing of an agreement with Ayres covering the supply of 100 shipsets of LHTEC CTP800-4T turboprops for the LM200 Loadmaster.
The 250-C30R/3, which uses full-authority digital electronic control, is a derivative of the -C47 engines certificated for Bell's Model 407 and the McDonnell Douglas MD600N. It also incorporates a new high-flow impeller and diffuser in the compressor.
The CTP800-4T is a 2,010kW (2,700shp) commercial derivative of the T800 destined for the US Army's Boeing-Sikorsky RAH-66 Comanche and produced in association with AlliedSignal.
