Gas Turbine Engine Lubricant Specifications: Current Technical Review and Future Direction
This AIR describes the current scientific and engineering principles of gas turbine lubricant performance testing per AS5780 and identifies gaps in our understanding of the technology to help the continuous improvement of this specification.
Qualification of a turbine oil formulation to AS5780 is now recognized as an integral part of most aviation equipment manufacturer’s oil approval processes. The E-34 Committee identified the need to develop this document based on inputs, questions, and concerns from gas turbine lubricant customers, equipment manufacturers, military authorities, and civil aviation authorities. The intent is to provide a clear and concise reference which will help guide the direction of the committee’s efforts in refining AS5780.
