An analytic and experimental study was made of an electromagnetic technique for the in-flight measurement of chemical rocket exhaust gas velocity vector. A ground test design, using an alternating magnetic field, was fabricated and tested on 40:1 and 10:1 area ratio nozzles with a gaseous oxygen-methane propellant combination. The ability of the E-M device to deliver a reproducible output voltage as a linear function of rocket exhaust gas velocity was demonstrated. However, at the present time, calibration for varying flow rates is required. Test results also suggest a possible extension of the electromagnetic technique to the measurement of mixture ratio, mass flow rate and other rocket engine parameters. Techniques for adapting the electromagnetic approach to ground and flight test applications are discussed. (Author)
