Abstract:

The use of a meter of suitable design may make it possible to measure the pro ile of velocity and electrical conductivity of ionized air flowing over a re-entry vehicle. Three methods are discussed the multiple primary coil the multiple sensing coil and the variable displacement technique. For the variable displacement method, the sigma u profile where sigma is the average conductivity mhosm and u is the average velocity msec is obtained in terms of the Fourier transform of the meter signal and the magnetic field geometry. Experimental results obtained using the multiple sensing coil method show favorable sensitivity as indicated by more than a factor of two change in signal between the outermost coils. Author
