Guidelines for Characterization of Gas Turbine Engine Total-Pressure, Planar-Wave, and Total-Temperature Inlet-Flow Distortion

2024-04-02
WIP
ARP6420A
The turbine-engine-inlet flow distortion descriptors summarized in this document apply to the effects of inlet total-pressure, planar-wave, and total-temperature distortions. Guidelines on stability margin, destabilizing influences, types and purposes of inlet data, AIP definition, and data acquisition and handling are summarized from AIR5866, AIR5867, ARP1420, and AIR1419. The degree to which these recommendations are applied to a specific program should be consistent with the complexity of the inlet/engine integration. Total-pressure distortion is often the predominant destabilizing element that is encountered and is often the only type of distortion to be considered, i.e, not all types of distortion need to be considered for all vehicles.

Engine and Transmission Identification Numbers

2024-03-18
CURRENT
J129_202403
This SAE Recommended Practice has been established to provide direction for the design and installation of an identification number (IN) as assigned to vehicle engines, transmissions, and transaxles. The IN is used for tracking or traceability of these components. In adhering to these recommended practices, facility of application in factory production and appearance quality are matters for manufacturer control. Reference SAE J853.
