ARP4729A
This SAE Aerospace Recommended Practice (ARP) provides technical design and application information related to the generation, distribution, control, and utilization of aircraft 270 VDC electrical power systems and support equipment. This document also provides references and definitions to permit comparisons of various electrical systems and components.

ARP826A
This document covers resolvers which are used to perform coordinate transformations as well as sine and cosine computations. It includes both the categories of compensated and uncompensated resolvers which perform these functions. Linear resolvers are also included because of their similarity to resolvers.

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.

ARP497B
In order to ease the equipment design engineer's problem and at the same time provide a basis for more accurate comparable measurements between manufacturer and user, this recommended practice sets up "standard conditions" for design assurance testing and tabulated values which differ from previous publications by requiring the motor to be in a warmed-up condition which approximates its average use temperature. These conditions and the basic tests to which the tabulated characteristics refer are grouped in section 2.2 (Design Assurance) and compose a complete list of defining characteristics of the motor. This recommendation establishes objectives for high performance control motors to be used with aeronautical and associated equipment in protective enclosures or completely within the shell of the aircraft so that they are subjected only to the internal climate conditions of heat, cold, shock, vibration, altitude, and humidity.

The scope of this report is to capture the fundamental principles of selecting a wire size for an aerospace application using the method prescribed in SAE AS50881 standard. Also, provided in this report are additional calculations to ensure the wire selection will adequately perform in a particular design function including meeting environment constraints. Some of the calculations in this report have been simplified to demonstrate the process for validating the wire size selections for a particular design application. More precise calculations should be investigated and evaluated to ensure proper assessment of each individual calculation in this report.
