The scope of this SAE Aerospace Information Report (AIR) is to present a guide for the determination of probable power output and the effect on the aircraft system that will be experienced when operating three-phase motors with one phase open. Unfortunately, the above subject cannot be resolved by specific rules. Modern aircraft or missile electrical systems are composed of a wide variety of electrical and electronic components. These components react differently under identical impetus due to the latitude of their design. This latidue of design must be allowed wherever possible to the accessory designer due to the various specification requirements. Therefore, it cannot be over-emphasized that the effect on the airplane or missile system, as well as motor operation, of three-phase motors on two-phase power must be thoroughly investigated.

A RADIOACTIVE tracer method for measuring connecting-rod bearing wear as it occurs is presented. A bearing wear mechanism is proposed which is substantiated by wear measurements using the above technique. Effects of operating variables and lubricating oils are discussed.

The paper describes increased bearing capacity from 1918 to 1956 based on New Departure Laboratory endurance test results and shows an increased capacity trend up to about 1946 at which time the optimum steel cleanliness of 52100-51100 steel was obtained by an air melting practice. The paper describes further advance in bearing capacity by the use of vacuum melting practices and also indicates that optimum cleanliness has not been consistent due to inability to control the process to the degree required for ball bearing steels.

The John Deere Waterloo Tractor Works, as manufacturers of farm tractors, does not manufacture oil seals. We rely on the manufacturers of oil seals for design assistance. After establishing the initial design, laboratory and field tests are required for verification. One of the seal applications is on the crankshaft which must keep crankcase and transmission lubricants separated. Reliability and long life are imperative. Alertness as to the effect of detail changes on seal life is necessary to maintain long service life. The front wheel bearing seals may be subjected to submersion in water and mud. Packing, lip and face type seals have been tested with the face type proving the most rugged, although the most costly of the three types. A problem of design and space which was encountered in a hydraulic pump was overcome by design changes in the seal and in the pump. Constant vigilance on assembly methods and tool maintenance is a requirement to keep quality level high.

The motion of a ball in a high-speed ball thrust bearing is being examined experimentally. A high-speed movie camera has been employed to photograph marked balls in a high-speed angular contact bearing both with and without a cage. The technique has produced clear, useful pictures. Although analysis of the pictures is not complete, the preliminary data indicate that there are differences between the predicted and experimental results.
