Book excerpt: Summary: The effect on the propulsive efficiency of locking or windmilling one propeller of a six-blade dual-rotating-propeller installation was determined in the Langley propeller-research tunnel. Tests were made of both pusher and tractor configurations, with the unpowered propeller both leading and following the powered propeller, which was set at a blade angle of 40°. The maximum propulsive efficiency of the powered propeller in combination with the locked or windmilling propeller was, in all cases, lower than that of the powered propeller operating alone. The locked propeller gave greater maximum propulsive efficiencies when used as a contravane to remove rotational energy from the slipstream than when used as a means for imparting initial twist to the air. The windmilling propeller, however, was equally efficient both leading and following the driven propeller. In the tractor installation, smallest losses in maximum propulsive efficiency were obtained when the unpowered following propeller was locked at a blade angle of 90° and when the unpowered leading propeller was allowed to windmill at a blade angle of 45°. In the pusher installation, equal losses in maximum propulsive efficiency were obtained when the unpowered following propeller was either locked at 90° or windmilling at 55°, but the unpowered leading propeller gave smallest losses when windmilling at 55°.
