This SAE Aerospace Information Report is intended to provide advanced methods for wire selecting and sizing in aerospace application as a continuation of AIR6540, Fundamentals in Wire Selection and Sizing for Aerospace Applications. Also, it will provide valuable information for the electrical design engineer to verify the proper wire selection and validate a set of system design requirements which includes meeting environmental and installation constraints.
EPS stability is an essential property that defines EPS ability to provide secure operation under required range of operation scenario. Power system stability is defined as “the ability of an electric power system, for a given initial operating condition, to regain a state of operating equilibrium after being subjected to a physical disturbance, with most system variables bounded so that practically the entire system remains intact”. This is applicable for AC and DC systems and has to address steady state conditions, transient conditions as well as high power loads connection / disconnection on the network.
This document provides guidance on key areas of system design to achieve high performance and high reliability for mission critical aerospace systems and platforms. The fundamental element of a reliable, functional aerospace fiber optic application is the system design. It is the system designers’ task to define the methods, components, installation and processes supporting the transmission of the optical signal through the platform, while providing a physical layer with the necessary performance, reliability, and readiness for the application.
The need for developing this standard is driven by the quickly evolving field of electrified propulsion for aircraft. Industry is moving forward in development of a broad range of high voltage primary power systems. There is an immediate need to standardize power quality requirements for design, analysis, verification, and testing for these types of systems.
This SAE Aerospace Standard (AS) defines the testing methods for all aerospace optic cables. The application of the test methods are defined in the slant sheets. Technical, dimensional, mechanical and operating performance requirements for the associated aerospace fiber optic cables are detailed in the applicable specification slant sheet. In the event of conflict between this standard and the slant sheet, the slant sheet shall take precedence.
