Human Intoxication Following Inhalation Exposure to Synthetic Jet Lubricating Oil

Clinical Toxicology, 1977
A previously healthy member of an aircraft flight crew was acutely incapacitated during flight with neurologic impairment and gastrointestinal distress. His clinical status returned to normal within 24 hr. The etiology of his symptoms was related to an inhalation exposure to aerosolized or vaporized synthetic lubricating oil arising from a jet engine ...

CFD investigation on the influence of jet velocity of oil-jet lubricated ball bearing on the characteristics of lubrication flow field

2015 International Conference on Fluid Power and Mechatronics (FPM), 2015
Oil-jet lubrication which is widely applied in aero engine, turbo machinery, high power transmission system is one of the most common form of the high speed bearing lubrication. The complex oil-air two-phase flow will exist in the cavity of the oil-jet lubricated high speed rolling bearing because of the stirring of the rolling elements and the cage ...

The Ball-on-Cylinder Test for Evaluating Jet Fuel Lubricity

A S L E Transactions, 1968
For 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 ...

Effect of esters on lubricity of hydrotreated jet fuel

Chemistry and Technology of Fuels and Oils, 1984
The 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 ...

Elemental analysis of jet engine lubrication oil and jet fuel using in-air PIXE

International Journal of PIXE, 2018
To understand the elemental characteristics of the exhaust particles from a jet aircraft, we performed an element analysis using an in-air PIXE system of the different lubrication oils of a jet engine (Mobil Jet Oil II, Mobil Jet Oil 254 and Eastman Turbo Oil 2380) and the jet fuel (JET A-1) to determine the effects on the exhaust particles.

Effects of monoesters of dicarboxylic acids on jet fuel lubricity

Chemistry and Technology of Fuels and Oils, 1986
The authors have prepared monoesters of dicarboxylic acids (DCAs) and aliphatic alcohols to study their effects on jet fuel lubricity. The effects of the synthesized compounds on the lubricity of a hydrotreated jet fuel were evaluated in a KIIGA-2 unit.

Effects of pulse voltage on piezoelectric micro-jet for lubrication

Microsystem Technologies, 2016
A novel piezoelectric micro-jet for bearing lubrication is presented in this paper, and the micro-jet is working at the slapping mode. The micro-jet is embedded in the bearing system, and add little mass or volume of the system. In order to meet the different requirements for different applications and to improve the injection performance of the micro ...

Experimental verification of nanoparticle jet minimum quantity lubrication effectiveness in grinding

Journal of Nanoparticle Research, 2014
In our experiment, K-P36 precision numerical control surface grinder was used for dry grinding, minimum quantity lubrication (MQL) grinding, nanoparticle jet MQL grinding, and traditional flood grinding of hardened 45 steel. A three-dimensional dynamometer was used to measure grinding force in the experiment.

Simulation research on bearing lubricating micro-jet driven by piezoelectric ceramic

2017 8th International Conference on Mechanical and Intelligent Manufacturing Technologies (ICMIMT), 2017
In order to solve the problem of the lubrication failure of bearing in Control Moment Gyroscope, this paper designs a kind of bearing lubricating device based on piezoelectric micro-jet theory. The lubricating oil is ejected by the device and then act on the bearing depend on the pressure waves which generated by piezoelectric vibrator.
