CH-47A CHINOOK ENGINE LOAD SHARING
Abstract
The Army is concerned with the problem of unequal load sharing by the engines in its multiengine helicopters. Findings of an engine load-sharing study conducted on the CH-54A Skycrane helicopter in 1965 led to a similar study on the CH-47A Chinook helicopter. Airspeed, altitude, engine gas producer rpm, engine torque, exhaust gas temperature, main rotor rpm, and outside air temperature were recorded during various flight conditions. The gross weight at takeoff and landing and the barometric pressures were also recorded as supplemental data. The data are presented in a series of histograms and tables showing the variations in engine load sharing as a function of the other aircraft parameters. It was found that for the CH-47A Chinook, the relative frequency of occurrence of torque splits greater than 20 percent is less than one-half that for the CH-54A Skycrane.
