EFFECTS OF TWO SPINNER SHAPES ON THE PRESSURE RECOVERY IN AN NACA 1-SERIES D-TYPE COWL BEHIND A THREE-BLADE PROPELLER AT MACH NUMBERS UP TO 0.80

Ashley J. Molk, R. M. Reynolds

Abstract

Report presenting an investigation to determine the effects of two spinner shapes on the pressure recovery in an NACA 1-series D-type cowl behind a three-blade propeller with fairly thick shanks. Data were obtained at a range of Mach numbers, inlet velocity ratios, blade angle ratios, and a specified Reynolds number.
