Adapting the Automotive Alternator to the Light Commercial Airplane Environment 660203

The self-rectifying automotive type alternator is being modified for light airplane usage. The alternator is rapidly replacing the conventional d-c generator in light commercial airplanes because of its greater output at low speeds, weight savings, simplicity of control, and eventual cost savings.
The change from d-c generator to self-rectifying alternators has required that the airplane's electrical system and accessories also be modified to accept the inherent electrical “noise” developed by the self-rectifying alternator.
These first applications of the automotive alternator are the beginning of a series of electrical system improvements that lie ahead for the industry.
