OIL SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18337717 titled 'OIL SYSTEM
The patent application describes a method of operating a gas turbine engine with a heat exchange system to transfer heat between oil and fuel.
- The method involves transferring heat from the oil to the fuel at cruise conditions, facilitating control of the oil temperature on entry to the main gearbox.
- The heat exchange system is designed to transfer 200 to 600 KJ/m of heat from the oil to the fuel.
- The oil entering the heat exchange system has an average temperature of at least 180°C at cruise conditions.
- The primary oil loop system supplies oil to lubricate the main gearbox, ensuring smooth operation of the engine core components.
- By efficiently transferring heat between the oil and fuel, the method optimizes the performance and reliability of the gas turbine engine.
Potential Applications: - Aerospace industry for aircraft engines - Power generation for gas turbine power plants
Problems Solved: - Control of oil temperature in gas turbine engines - Efficient heat transfer between oil and fuel - Enhanced performance and reliability of engine components
Benefits: - Improved fuel efficiency - Extended engine lifespan - Enhanced overall engine performance
Commercial Applications: Title: "Efficient Heat Exchange System for Gas Turbine Engines" This technology can be applied in commercial aircraft, power generation plants, and other industrial applications requiring gas turbine engines for propulsion or power generation.
Questions about the technology: 1. How does the heat exchange system impact the overall efficiency of the gas turbine engine? - The heat exchange system improves efficiency by optimizing the temperature of the oil entering the main gearbox, leading to smoother operation and reduced wear on engine components. 2. What are the potential cost savings associated with implementing this heat exchange system in gas turbine engines? - The cost savings may include reduced maintenance costs, increased fuel efficiency, and extended engine lifespan, resulting in overall operational savings for aircraft operators and power plant owners.
Original Abstract Submitted
A method of operating a gas turbine engine having an engine core having a turbine, a compressor, a combustor to combust a fuel, and a core shaft connecting the turbine to the compressor; a fan located upstream of the engine core; a fan shaft; a main gearbox receiving an input from the core shaft and outputting drive to the fan via the fan shaft; a primary oil loop system to supply oil to lubricate the main gearbox; and a heat exchange system arranged to transfer heat between the oil and the fuel, the oil having an average temperature of at least 180° C. on entry to the heat exchange system at cruise conditions. The method includes transferring 200 to 600 KJ/mof heat from the oil to the fuel, using the heat exchange system, at cruise conditions, which may facilitate control of the oil temperature on entry to the main gearbox.
