Abstract:

On May 20, 1988, Boeing Helicopters was awarded a contract by the U.S. Army Aviation Systems Command AVSCOM and the NASA Lewis Research Center to conduct the Advanced Rotorcraft Transmission ART program. The ART program is structured to incorporate key emerging material and component technologies into an advanced rotorcraft transmission with the intention of making significant improvements in the state-of-the-art SOA. The objectives of the ART program are 1 Reduce transmission weight by 25 relative to SOA trends currently in the range of 0.40 lbhp. 2 Reduce transmission noise by 10 dB relative to SOA. 3 Improve transmission life and reliability, while extending Mean Time Between Removal MTBR to 5000 hours. The ART contract required Boeing Helicopters to select a baseline transmission design that was representative of SOA drive train production technology and then compare this design with an advanced configuration developed during the ART program. Boeing Helicopters selected a transmission sized for the Tactical Tilt Rotor TTR aircraft which meets the Future Air Attack vehicle FAAV requirements.
