Experimental Investigation of a Circulation Controlled Shrouded Propeller

Abstract

A preliminary experimental investigation was made on a 14.18 inch inside diameter, ten inch long, symmetrical airfoil shaped shroud equipped with blowing slots on a blunt semicircular trailing edge. The purpose of the investigation was to determine the effect of circulation control on the thrust of the shroud-propeller combination. Static tests were performed at three propeller blade pitch angles, three propeller speeds and three levels of inside slot blowing rates. Data recorded consisted of the propeller thrust and torque, shroud static pressures, total pressure in front of the inside struts, and total pressure at the blowing slot. Static pressure data was reduced to coefficient form and integrated to obtain thrust and normal force coefficients. This was converted to pounds and compared with the propeller thrust.
