An Experimental Determination of the Aerodynamic Drag Characteristics of Variable Geometry Rigid Bodies.

摘要

An investigation was made of the aerodynamic drag characteristics of two Variable Geometry Rigid Bodies (VGRB's). Results were obtained experimentally through the use of a low speed wind tunnel and an external wind-tunnel balance. Four wood models were tested representing two unique VGRB's in the full-volume and half-volume configurations. Results obtained with the smaller VGRB were compared to those obtained from an elongated body of revolution of equal length and volume. (Author)
