Aerodynamic Characteristics of an Axisymmetric Body Undergoing a Uniform Pitching Motion.

Abstract

An experimental investigation was conducted to determine the effect of a uniform pitching motion on a slender axisymmetric body while undergoing large excursions in angle of attack. Force and moment measurements were obtained for a slender tangent-ogive/cylindrical body over a range of Reynolds numbers from 50,000 to 140,000 while varying the angle of attack from zero to 90 degrees and the pitch rate between zero and 281 degrees per second. Smoke flow visualization studies were used as an aid in assessing wake vortex transitions.
