PRESSURE PATTERNS AND MAGNITUDES IN SCALE MODEL TALOS TUBE LAUNCH TESTS,
Abstract
To determine the pressure effects on a TALOS missile and booster if launched from a vertical tube, a series of 1/36 scale tests was made. Designed to study total and static pressures, pressure patterns and the phenomenon known as the transietn shock, the experiments were undertaken as a preliminary measure to a subsequent full scale rocket firing. A compressed air system and mounting machinery in existence at the Forest Grove Station were utilized, necessitating only the manufacture of a missile-booster model and a miniature launch tube. A total of 88 tests was completed under steady state conditions while monitoring various combinations of 35 pressure taps on the missile-booster body and throughout the launch tube. The transient shock-wave was successfully reproduced on a scope and photographed 5 times. The results of the steady state tests showed rather low pressures and a favorable pressure pattern which should have no serious adverse structural effects on either the missile or booster in a full scale tube launch. The highest transient shock recorded was 4.73 psi which was considerably lower than anticipated. The results for the 5 tests, however, were very uniform (3.83 to 4.73 psi). (Author)
