Flight Tests to Determine the Effect of Length of a Conical Windshield on the Drag of a Bluff Body at Supersonic Speeds

Abstract

An investigation was made to determine means of reducing drag of blunt nose bodies to values comparable to those of pointed nose bodies by varying length of conical windshield. Increasing length of conical windshield mounted ahead of bluff body, moving at supersonic speeds, decreases drag. effect is greatest for short windshields and increases with Mach number. Conical windshield of small dimensions can increase effective fineness ratio at supersonic speeds.
