<div class="htmlview paragraph">The poor performance of some high purity jet fuels appears to be related to polar compounds in the fuel and not to viscosity, volatility, or sulfur and nitrogen compounds. Surface active additives such as corrosion inhibitors markedly improve lubricity.

THE JET AGE of today and the Space Age of tomorrow would not be possible without the recent developments in specialised lubricants that have increased the capabilities of fluids, greases, solid films, plastics, ceramics and other specialised lubricating agents. The present and potential use in aeronautical and astronautical flight have imposed and will

Effect of esters on lubricity of hydrotreated jet fuel
Chemistry and Technology of Fuels and Oils, 1984The authors synthesized a number of esters of stearic acid with polyhydric alcohols and ran comparative tests on aliphatic alcohols to determine their effects on the antiwear properties of the fuel. They conclude that the differences in effectiveness in improving the lubricity by the use of aliphatic alcohols and the full and partial esters of ...

The Physics of Fluids
An interacting and complicating phenomenon between the angular contact ball bearing in the high-speed level and the oil jet flow is widely investigated by the computational fluid dynamics (CFD) method to track the oil–air two-fluid. First of all, the oil

The Ball-on-Cylinder Test for Evaluating Jet Fuel Lubricity
A S L E Transactions, 1968For evaluating the lubricating qualities of jet fuels, the ball-on-cylinder device appears to be particularly suitable. It can operate at low enough loads so that subtle differences in fuel quality can be detected. Examples are given of the effect of refining, the differences in additive action, the importance of test atmosphere, and the influence of ...

Proceedings of the Institution of mechanical engineers. Part J, journal of engineering tribology, 2020
In aeroengine industry, the oil jet layout significantly influences lubrication of high-speed and heavy-load transmission gears, as there is only extremely limited meshing clearance for the oil stream jetting into and an inevitable blocking effect of ...
