Publication number: 20220364511Abstract: A fuel system for a turbine engine. The fuel system includes a fuel/air mixer configured to mix air with fuel in a controlled fuel/air ratio, the fuel/air mixer having a body defining a chamber. The fuel system also includes a fuel nozzle in fluid communication with the fuel/air mixer. The fuel nozzle is configured to inject fuel into the chamber of the fuel/air mixer. The fuel nozzle is located forwardly relative to the body of the fuel/air mixer so that a jet-in-crossflow of the fuel is angled relative to a foot of the body of the fuel/air mixer.Type: ApplicationFiled: May 11, 2021Publication date: November 17, 2022Inventors: Neeraj Mishra, Jayanth Sekar
