description abstract	The characteristics of a turbine and a propeller were investigated to determine the conditions of maximum-efficiency operation when utilized as an independent turbine-propeller combination. The procedure used to determine the conditions of maximum efficiency and the speed ratio between the turbine and the propeller is illustrated. This procedure involved the use of a method of matching turbines and propellers. By the use of this method, the conditions for maximum-efficiency operation can be defined by turbine-inlet temperature, pressure ratio, and propeller speed for each flight condition. The relation between these parameters is adaptable to independent control of turbine-propeller speed when interaction between the turbine-propeller combination and the gas generator is either nonexistent or when the effects of interaction can be sufficiently damped.
