Managing Higher Voltages in Aerospace Electrical Systems

Published by: 2017-04-03 / 2017-04-03 / 41 pages

This SAE Aerospace Information Report (AIR) considers the issue of proper design guidance for high voltage electrical systems used in aerospace applications. This document is focused on electrical discharge mechanisms including partial discharge and does not address personnel safety. Key areas of concern when using high voltage in aerospace applications are power conversion devices, electrical machines, connectors and cabling/wiring. The interaction between components and subsystems will be discussed.

The AIR is intended for application to high voltage systems used in aerospace vehicles operating to a maximum altitude of 30000 m (approximately 100000 feet), and maximum operating voltages of below 1500 VRMS (AC)/1500 V peak (DC). These upper voltage limits have been incorporated because this report focuses on extending the operating voltage of non-propulsive electrical systems beyond that of existing aerospace systems. It is noted that electrical systems for electrical propulsion may consider operating voltages beyond 1500 VAC/DC.

GENERAL ENVIRONMENTAL REQUIREMENTS FOR DEEP SUBMERSIBLE VEHICLES AND SUBMARINES

Published by: 1969-04-15 / 1969-04-15 / 8 pages

The scope of this HIR is to specify general oceanographic environments. Specific environmental requirements shall be specified in a detail specification. Specific requirements are in the state of constant flux because the ocean environment is constantly changing and the changes occur not only on a seasonal basis but also monthly, weekly, daily, and in some cases even hourly.

This HIR is to be used as a guide only.

Air Cargo Unit Load Devices – Reference Documents

Published by: 2017-04-13 / 2017-04-13 / 11 pages

The present SAE Aerospace Information Report (AIR) provides a list of the main government regulations, SAE and international standards, and standing industry recommendations applying to air cargo unit load devices (pallets, nets, and containers) to be loaded with either baggage or freight on board civil transport aircraft.

It is intended to provide unit load devices designers, purchasers, and operators as well as civil transport aircraft and aircraft cargo systems designers within the industry with a list of the available document references to cover the other aspects that do not all directly pertain to airworthiness and testing, listed in 1.1 of AS36100, – Air Cargo Unit Load Devices – Performance Requirements and Test Parameters [TSO-C90].

The scope of the listed documents covers airworthiness and continued airworthiness requirements, design and testing methods, design specifications, unit load devices accessories, and the main published rules for their proper operation/utilization and operating staff training.

Ice Undercutting Test Method for Runways and Taxiways Deicing/Anti-Icing Chemicals

Published by: 2017-03-15 / 2017-03-15 / 10 pages

This test method provides stakeholders (runway deicing chemical manufacturers, users, regulators and airport authorities) with relative ice undercutting capacity of runway deicing chemicals, by measuring the area of ice undercut pattern as a function of time. Such runway deicing chemicals are often also used on taxiways and other paved areas.

This test method does not quantitatively measure the theoretical or extended time of ice undercutting capability of ready-to-use runway deicing/anti-icing chemicals in liquid or solid form.

Distortion Synthesis/Estimation Techniques (Stabilized: Mar 2017)

Published by: 2017-03-21 / 2017-03-21 / 15 pages
SAE AIR5826B provides a review of published methods that have been used to provide estimates of the levels of distortion and/or the concomitant loss of stability pressure ratio that can occur when the recommended full complement of aerodynamic interface plane high-response instrumentation is not used when obtaining inlet data. The methods have been categorized based on the underlying mathematical representation of the aerophysics. Further, the use of maximum value statistics, which has been used to further improve the results where short-duration time records have been employed, is discussed.

Ice Melting Test Method for Runways and Taxiways Deicing/Anti-icing Chemicals

Published by: 2017-02-21 / 2017-02-21

This test method provides stakeholders (runway deicing chemical manufacturers, users, regulators, and airport authorities) with relative ice melting capacity of runway deicing chemicals, by measuring the amount of ice melted as a function of time. Such runway deicing chemicals are often also used on taxiways and other paved areas.

This test method does not quantitatively measure the theoretical or extended time ice melting capability of ready-to-use runway deicing/anti-icing chemicals in liquid or solid form.
