Abstract:

The potential of the neopentyl polyol esters to survive higher surface temperatures without forming excessive harmful coke deposits was investigated. This study consisted of an engineering evaluation of the lubricant deposition-degradation characteristics which could have a significant bearing on the maintainability and reliability of future high thrust to weight ratio engines to be incorporated into the Navy inventory. Relationships were then established between these characteristics and chemical composition of the basestock materials, and to a lesser degree, the oxidation inhibiting packages. The intention of this investigation was to provide cause and effect relationships for the phenomena which were either the strengths or weaknesses of the current formulation philosophies. Such an understanding could open the way to meet the more demanding future requirements. It is equally desirable that engine designers utilize the information presented as a guideline for avoiding those environments which are most conducive to the generation of lubricant degradation products that can jeopardize engine operation.
