MEASUREMENT OF BASE PRESSURE IN FREE FLIGHT,
Abstract
The dependency of base pressure on Mach number M in cylindrical bodies with hemispherical ends, in the range of M numbers 1.32 to 2.91 and Reynolds numbers (changing proportionately to the velocity) from 900,000 to 2,000,000, was investigated on a modern ballistic projectile. Tests were performed by a method in which the deflection of the upper diaphragm was measured. This diaphragm was in the bottom of the projectile and covered a small chamber which was filled with air under atmospheric pressure and having the same temperature as that of the surrounding medium.
