Book excerpt: The effort undertaken by Boeing Defense & Space Group, Helicopters Division, to conduct the Advanced Rotorcraft Transmission (A.R.T.) program is summarized in this report. This program was structured to incorporate key emerging material and component technologies into an advanced rotorcraft transmission with the intent of making significant improvements in the state of the art The specific objectives of this program are 25 percent reduction in weight, lO-dB reduction in noise, and a 5,000 hour MTBR rotorcraft transmission. All of these objectives were attained. Boeing concentrated its work on high-gain and comparatively high risk technologies that could demonstrate the program objectives before full scale aircraft development Component development testing was conducted to evaluate high risk concepts before finalizing the advanced transmission configuration. Some of the advanced technology component tests conducted included hybrid bearings, bidirectional tapered roller bearings, precision net forged gears, active noise cancellation, titanium gears, HCRNIV tooth form spur gears, and noise reduction by variations in contact ratio and tooth form. The results of these tests are provided in this report. Trade studies conducted under this contract indicated that applying the A.R.T. drive system to a new aircraft design will have a great impact on aircraft gross weight and engine power rating requirements, in addition to a significant effect on the acquisition and operating costs of the aircraf. Potential cost savings of more than $300 million on a production run of 600 TTR aircraft or approximately half a million dollars cost reduction per aircraft could be realized.

Available in PDF, EPUB and Kindle. Book excerpt: A preliminary experimental investigation of the thermal behavior of high-speed helical gears will be presented. A full-scale torque regenerative test stand has been built to test a representative helical gear train as that used in tiltrotor aircraft. Power loss and temperature data from a wide range of operating conditions were measured. Loop power ranged up to 3730 kW (5000 hp). Drive system components representative of flight quality hardware were used in the test program. The results attained in this initial study indicated that windage losses due to the high rotational speeds that were tested were far more important than the losses due to the gear meshing losses.
