Application: Distributed electric and hybrid fans for distortion tolerance of turbofan engines (Patent ID: US20240209795A1)
The patent filed by Rolls-Royce Holdings Plc describes a gas turbine engine with a primary fan and an engine core. The primary fan, including a fan rotor and fan blades, is mounted to provide thrust, while the engine core, comprising a compressor, combustor, and turbine, drives the primary fan by compressing air and generating hot, high-pressure products. Additionally, an auxiliary fan system with electric fans is included to minimize pressure and swirl distortions in the engine by adjusting fan rotation speeds based on pressure differentials in the flow path.
The patent further details the control unit of the gas turbine engine, which includes sensors to measure pressure, a controller to adjust fan speeds based on pressure thresholds, and a memory with preprogrammed aircraft maneuvers for fan speed profiles. The electric fans in the auxiliary fan array can pivot relative to the primary fan, allowing for directional changes based on pressure measurements. The arrangement of the electric fans, struts, and outer case around the engine core and primary fan is designed to optimize airflow and minimize distortions. The method outlined in the patent involves conducting airflow through the engine, measuring pressure, and adjusting electric fan speeds to reduce pressure and swirl distortions, with the option to pivot the fans for directional control based on pressure readings.
