GAS TURBINE ENGINE COMBUSTOR WITH DILUTION PASSAGES - A simplified explanation of the abstract

This abstract first appeared for US patent application 17969913 titled 'GAS TURBINE ENGINE COMBUSTOR WITH DILUTION PASSAGES

The patent application describes a combustor with an annular liner, a dome wall, a combustion chamber, at least one fuel cup, and at least one dilution passage. The fuel cup is located on the dome wall and connects to the combustion chamber, with a defined fuel cup centerline. The dilution passage ends in a slot opening on the dome wall, with the slot having a longitudinal body axis.

• The combustor includes an annular liner, dome wall, combustion chamber, fuel cup, and dilution passage.
• The fuel cup is positioned on the dome wall and links to the combustion chamber.
• A fuel cup centerline is defined within the fuel cup.
• At least one dilution passage terminates in at least one slot opening on the dome wall.
• The slot has a longitudinal body axis.

Potential Applications: - Gas turbine engines - Aircraft propulsion systems - Industrial heating systems
