Development, Verification, and Validation of a Thermal Model for Determining Current Derating Design Limits of Aerospace Wires and Wire Bundles

The information about the standard:

Designation standards: SAE ARP7987
Publication date standards: 1.8.2021
Country: American technical standard
Category: Technical standards SAE

Annotation of standard text SAE ARP7987 :

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.
