Working Model of Lubrication System used in Gas Turbine Engine

Lubrication systems in aircraft play a crucial role in ensuring the efficient operation and longevity of engine components. In turbine engines, oil is circulated under pressure through bearings, gears, and other critical components, with filtration and temperature control mechanisms to maintain optimal performance. Advances in synthetic lubricants have further improved thermal stability, viscosity retention, and wear protection, enhancing engine efficiency and reliability. This paper explores the types, working principles, and advancements in aircraft lubrication systems, emphasizing their role in aviation safety and performance. The study also discusses future trends, such as self-monitoring lubrication systems and nanotechnology-based lubricants, which aim to enhance durability and efficiency. Key Words: Aircraft lubrication, dry-sump system, wet-sump system, synthetic lubricants, turbine engine, aviation maintenance.
