Comparison of predicted and measured temperatures of UH-60A helicopter transmission [PDF]

open access: yes
The 2109-kW (2828-hp) UH-60A Black Hawk helicopter transmission was one of the transmissions used to obtain an experimental data base. Component improvements or new transmission concepts can thus be evaluated by comparison with the established data ...

Power Flow and Efficiency for Planetary Gear Transmission

open access: yesJixie chuandong, 1998
Efficiency is an important characteristic of transmission quality for planetary trains.In order to calculate the efficiency for simple and complex planetary gear trains,a common formula is necessary.In this paper,a suitable formula is given,and the problem about power flow plan is discussed.At the same time,the relationship between power flow and ...
