SHROUDED PROPELLER INVESTIGATIONS: TOTAL AND STATIC PRESSURE VARIATIONS ACROSS THE ANNULUS OF A SHROUDED PROPELLER MODEL

Abstract

Wind tunnel tests were conducted in which both total and static pressure surveys were made at six radial stations in the annulus of a shrouded propeller model. Pressure surveys were made both upstream and downstream of the plane of a 4-bladed and a 6-bladed variable pitch propeller. The model configuration consisted of a 0.50 chord/diameter ratio shroud which had provisions for changing the inlet configuration from a streamlined or high speed shape to a bellmouth shape and changing the exit configuration from a non-diffused to a diffused exit. The centerbody of the model was constant at 30% of the shroud inner diameter. Pressure variations were recorded throughout a range of advance ratios from zero to 2.0 at three propeller pitch angles and model angles of attack from zero to 90 degrees. (Author)
