In article <5653@orca.wv.tek.com>, philb@ptolemy.TEKTRONIX.COM (Phil Biehl;685-2122;60-850;684-2867;orca) asked about "hot wire anemometors"


I don't know how they are used as anemometers for planes, but I am
aware (peripheraly) of their use as a replacement for gyrocompases in
moderately high dynamic envirnoments (remote controled vehicles).

In essence, you blow an air stream between two "hot wires" and the
differential cooling is a measure of the deflection of the air jet
and the rate of rotation of the platform.
