    RECOGNITION of the need for better protection of aircraft electric systems is indicated by the increasing use of reverse current circuit breakers in d-c generator circuits. Improved protection, however, must be extended to the entire electrical system and not confined to the generating equipment. Protective equipment for low capacity circuits in 28-volt d-c systems has been available. There has be... View full abstract»

    This paper analyzes the protection of a typical 28-volt d-c distribution system for a large multiengine aircraft. Methods of making a load study and fault study are illustrated. From the analysis of this system, conclusions are drawn regarding bus and feeder fault protection and arrangement. It is shown that by relatively minor modifications in bus arrangement a considerable increase in the degree... View full abstract»

    THE work that must be expended to actuate adjustable flight surfaces and to operate the landing gear, bomb doors, and other movable structures on aircraft often exceeds pilot capabilities. At the same time, the increase in physical size of aircraft in recent years has all but ruled out mechanical transmission systems. To provide for power amplification and to eliminate mechanical links, the aircra... View full abstract»

    This paper outlines certain difficulties experienced with diesel-electric locomotives on the Missouri-Kansas-Texas Railroad since the first road service units were placed in operation during 1947. With four different makes of locomotives, totalling 197 units operating on 3,242 miles of railroad, furnishing the basis for the observations outlined, it can be assumed that similar difficulties have be...

    At the Southern California Co-operative Wind Tunnel, part of the need for rapid and accurate recording of instrument readings on tabular data sheets has been met by the development of a new automatic-translating device. This device has unusually low torque and is especially suitable for use with self-balancing potentiometers. The device picks up the reading as a whole number and electrically trans...
