WIND-TUNNEL INVESTIGATION OF THE EFFECTS OF THRUST, SHROUD LENGTH, AND SHROUD CAMBER ON THE STATIC STABILITY CHARACTERISTICS OF SHROUDED PROPELLERS.
Abstract
Several related shroud profiles were tested, including uncambered, and positively and negatively cambered, to determine effects of geometric variables and thrust coefficient. Thrust coefficient and shroud length were found to affect slopes of lift curve and pitching-moment curve in agreement with trends but not with all actual numerical values predicted by existing theory. Propulsive efficiency was measured for shroud-propeller-center body combination and base pressure of body.
