Pressure Measurements in a Liquid Filled Cylinder Using a Three Degree of Freedom Flight Simulator.
Abstract
A three degree of freedom flight simulator was used to simulate the angular motion of a spin-stabilized projectile in order to measure internal pressures on a liquid filled cylinder. The flight stability of liquid filled shell is often determined by linearized theory and tests of subscale models. This simulator is sufficiently large to produce full scale tests and can acomodate a large number and variety of TRANSDUCDERS. Pressure and accelerometer measurements were taken in a continuous fashion on a liquid filled cylinder endwall and sidewall. The Reynolds number was 18,200. Tests at several different AMPLITUDES of yaw allowed for comparisons with linear theory. Nonlinear trends were observed. Measurements of the phase difference between the pressure and the yawing motion are presented. Pressure data are available for prograde and retrograde yawing motion, and they provide a verification of the theory applications for a wide range of the coning frequency. Keywords: rotating liquids, pressure measurement.
