Liquid Lubricants for Advanced Aircraft Engines

NASA Lewis Research Center

This NASA tribology technical report is dedicated to the study of liquid lubricants for high-performance engines.  It reviews chemical and physical properties, with special emphasis on oxidation and thermal stability.

The text presents a history of the development of jet engine lubricants--from the work of Frank Whittle of the Royal Air Force College in England--that led to the present-day synthetic oils with their advantages.  It covers the state of development of several candidate classes of fluids for use in advanced engines. 

You'll get an education and better understanding of the chemistry involved in fluid degradation, and learn how high-temperature fluid lubricants and base stocks are developed.

Much of the work in this investigation is for oils that must operate in engines at Mach 2.5 to 3, at temperatures of 204ºC (400ºF) to about 260ºC (500ºF).  The book explains how to overcome problems of lubricant oxidation, thermal instability, high volatility, and high pour points for low-temperature starting.

These topics are discussed and explained in detail:

  • Synthetic hydrocarbons
  • Polyalphaolefins (PAO)
  • Silahydrocarbons (SiHC)
  • Superrefined mineral oils
  • Neopentyl polyol ester
  • Improved silicones
  • C-Ethers
  • Triphenyl disiloxanes
  • Polyphenyl ethers
  • Perfluoropolyethers
  • Fluoroether triazines
  • Additives to high-termperature fluids
  • Use of an inerted lubrication system
  • Microfog once-through systems
For physical and chemical properties, the text covers:
  • Thermal stability
  • Corrosion-oxidation stability
  • Pour point
  • Density
  • Bulk modulus
There's also an extensive, 5-page bibliography, offering 83 technical references for further study.  Fifteen graphs, tables, charts, and diagrams support the text.

Following the treatise are five pages of (42) technical references suggesting further study.

This fine handbook will provide exceptional information for everyone who designs, builds, tests, or uses advanced mechanical devices that require special lubrication--including not only airplane engines, but also gas turbines, go-karts, motorcycles, racing cars, racing boats, and other high-performance engines.

It's an official NASA report, full of esoteric scientific data.  In a word, it's a book by the experts, for the experts!  Literally millions of dollars were spent obtaining this critical yet hard-to-find data. 

This sampling of the superb illustrations are shown at greatly reduced resolution size:
