OUTLET GUIDE VANE ASSEMBLY FOR A TURBOFAN ENGINE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18086039 titled 'OUTLET GUIDE VANE ASSEMBLY FOR A TURBOFAN ENGINE
Simplified Explanation: The patent application describes a turbofan engine with an unducted rotor assembly and outlet guide vanes that have nonuniform spans along the circumferential direction.
- The turbofan engine includes a turbomachine.
- An unducted rotor assembly is drivingly coupled to the turbomachine, consisting of multiple unducted rotor blades.
- A plurality of outlet guide vanes are positioned downstream of the unducted rotor blades, with each vane defining a span that varies in the circumferential direction.
Key Features and Innovation:
- Unducted rotor assembly in a turbofan engine.
- Outlet guide vanes with nonuniform spans.
- Optimization of airflow and efficiency.
Potential Applications:
- Aircraft propulsion systems.
- Industrial gas turbines.
- Marine propulsion systems.
