Electrical Computing Resolvers

2017-11-30
CURRENT
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.

Precision Control Motors – 400 Cycles

2017-11-30
CURRENT
ARP497B
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 climatic conditions of heat, cold, shock, vibration, altitude, and humidity. Control motors larger than size #23 are not covered in this document.
