HOT GAS VELOCITY MEASURING DEVICE

Abstract

Conclusions and recommendations of all work conducted during the entire gas velocity measuring device program are presented. The objective of the program was to prove feasibility and deliver a breakboard test model of a rocket exhaust gas velocity measuring device which is independent of other gas parameters. The device is basically a magnetohydrodynamic generator in which the ionized rocket exhaust gas is used as the moving conductor within a magnetic field. The voltage generated normal to the gas flow is proportional to gas velocity in the field. The velocity measuring device consists of two Helmholtz magnetic coils having a uniform field between them and placed on an axis such that the rocket exhaust gas will pass between them in a direction perpendicular to the field. Probes on an axis 90 degrees from the coil axis pick up the electromotive force generated.
