SAE AS6502

This SAE Aerospace Standard (AS) provides classical propulsion system performance parameter names for aircraft propulsion systems and their derivatives, and describes the logical framework by which new names can be constructed. Aircraft propulsion technology continues to evolve and advance to meet changing requirements and challenges for improved performance and capabilities. This document addresses an industry need to characterize classical propulsion system performance parameter names, and describes the logical framework by which new names can be constructed. Nomenclature definitions issued by other industry organizations were reviewed and considered as well as the application of this standard to alternate engine cycles. The contents of this document were, originally, a subset of AS755E. Due to the growing complexity of station numbering schemes described in AS755, and a desire to expand the nomenclature section to include a fuller representation of “classical” (legacy use) names, a decision was made to separate its “station numbering” and “nomenclature” content into two separate documents. This document, then, was created using the “nomenclature” half of AS755E. Both documents will continue to be improved and expanded as industry needs dictate. AS6502 has been reaffirmed to comply with the SAE Five-Year Review policy.
