Performance, duct pressure distribution and propeller inflow data are presented for 6-ft diam tractor and pusher ducted propellers at speeds from 0 to 50 mph; their use has been suggested as propulsion units for light aircraft, air cushion vehicles, etc; it appears that in this speed range duct geometry does not have strong influence on performance, but installation losses can be large if attention is not paid to this aspect of design; propulsive efficiencies of 80% or more should be expected.
