Introduction to Aircraft Lubrication Systems

Aircraft lubrication systems are critical for the efficient and safe operation of aircraft engines. These systems reduce friction between moving parts, dissipate heat, and prevent wear and corrosion. The modern aircraft lubrication system is complex, integrating various components to ensure engines operate under optimal conditions.

Components of the Aircraft Lubrication System

• Oil Reservoir: Stores oil and often includes a sight glass for level inspection.
• Oil Pump: Generally a gear or vane type, it circulates oil throughout the system.
• Oil Filter: Removes contaminants from the oil before it is circulated back into the system.
• Oil Coolers: Heat exchangers that reduce the temperature of the oil before it returns to the engine.
• Pressure and Temperature Sensors: Monitor system conditions to ensure safe operation.

Operation of Lubrication Systems

The aircraft lubrication system operates under specific pressures and flow rates, which are critical for maintaining engine integrity. Typically, the system operates at pressures ranging from 50 to 100 psi, and the flow rate can vary between 1 to 10 gallons per minute, depending on engine size and type.

During operation, the oil is pumped from the reservoir through the system via the oil pump. As it circulates, it lubricates engine components, picks up heat and contaminants, and is then filtered and cooled before returning to the reservoir. This cycle ensures continuous engine protection and efficiency.

Types of Lubrication Systems

There are primarily two types of lubrication systems used in aircraft:

• Wet Sump Systems: The oil is stored in the engine crankcase. This system is simpler but can pose challenges in managing oil temperatures.
• Dry Sump Systems: Here, oil is stored in a separate tank, not in the engine. This type allows for better temperature control and engine performance in various flight conditions.
