About This Item

The thermal modeling guidelines and best practices provided in this document are applicable to powered aerospace vehicle wires and wire bundles in thermal environments ranging from -65 to +260 °C (-85 to +500 °F) and pressures ranging from sea level to space vacuum. Currently the ARP only considers steady state and direct current conditions. The effects of wiring terminations and connectors are not addressed. Both can significantly impact the overall current derating and safety margins for a wiring system. This SAE Aerospace Recommended Practice (ARP) documents the basic guidelines for the development, verification, and validation of a thermal analytical model for determining ampacity and current derating limits of aerospace wires and wire bundles. The document will be updated as new models are developed and new information becomes available.
