Measurement of Base Pressure in Free Flight
Abstract
The dependence of base pressure on the Mach number M on cylindrical bodies having the front section in the shape of a hemisphere in the range of M numbers from 1.32 to 2.91 and on the Reynolds number R sub L (varying proportionally to the velocity) from 0.9 (middle dot) 1,000,000 to 2.0 (middle dot) 1,000,000 was investigated on a modernized ballistic unit. The experiments were carried out with respect to a method using the deflection of a rubber diaphragm placed in the bottom of the model and sealing off a small cavity filled with air at 1 atm and the temperature of the ambient medium.
