Abstract

Report presenting the flow fields at the propeller planes of six 40 degree sweptback semispan wing-fusleage-nacelle combinations to provide data and to enable the study of the characteristics of the flow fields and their effect on propeller-oscillating aerodynamic loads. Results regarding the propeller flow fields, oscillating aerodynamic loading, and upflow angles at the horizontal center lines of the propeller disks are provided
