DEVICE FOR GENERATING SIGNAL INDICATING SYNCHRO ROTATION SPEED

摘要

By combining three single-phase output voltages of a synchro, signals are obtained which are proportional to the sine and the cosine of the angle of rotation of the synchro shaft. Said signals are sampled at predetermined instants by switching means controlled by a clock voltage, and are applied to computing means which form a signal representative of the speed of rotation of the shaft of the synchro and of a change in the altitude at which an aircraft flies.
