Cooling of Lubrication System in Aircraft Engines Using Peltier’s Principle

Abstract

The increased complexity of the aircraft engines has added to the need of better lubrication system. Jet engine require better lubrication to reduce the friction. Better lubrication demand better cooling, pumping and better grade oil. cooling is the heart of the lubrication system. Temperature is one of the parameters that largely decides the properties of the oil. The temperature of the oil increases after the lubrication of engine parts. It is very much necessary to cool the oil to maintain the properties of the oil. There is a need of better cooling system to maintain an optimum temperature. Increase in temperature would result in failure of the bearing and other components. So, the engine oil should have all the properties to meet the requirement and its property should be withstood throughout the operation. Normal conventional cooling method would not meet the increasing requirement hence there is a need for better system. This paper introduces a new and efficient way of cooling using Peltier’s principle.  This is done by introducing Peltier’s cells in cooling system.
