- THE paper is divided into two parts: the first dealing with propeller unbalance types, amounts, major contributing factors, and methods of control; and the second dealing with airplane roughness caused by propeller unbalance, including a study of human susceptibility to such vibration.Mr. Best shows here that airplanes are not rough due to propeller unbalance unless either the structures or engine-mount combinations exhibit resonant characteristics. Since structural frequencies are not susceptible to close control, the author believes that proper engine-mount design is of prime importance in eliminating propeller unbalance roughness.
