Benefits of technology

The patent text is about controlling the amount of heat exchange in an electric propulsion engine. This can be achieved by reducing the speed of the fan, which helps to decrease the amount of heat being transferred from the engine. In simpler terms, this means reducing the engine's temperature to improve its performance.

Problems solved by technology

Regardless of the propulsion system utilized, various systems of the aircraft may generate a relatively large amount of heat during certain operating conditions of the aircraft.
However, the ram air heat exchangers may cause an undesirably high amount of additional drag on the aircraft, reducing an overall efficiency of the aircraft.

Abstract

An aircraft includes an aircraft heat source; a propulsion system including an electric propulsion engine, the electric propulsion engine including an electric motor and a fan rotatable by the electric motor, the electric propulsion engine further defining a fan air flowpath; a thermal management system including a heat source exchanger in thermal communication with the aircraft heat source, a heat sink exchanger in thermal communication with the fan air flowpath of the electric propulsion engine, and a thermal distribution bus extending from the heat source exchanger to the heat sink exchanger; and a control system operably connected to the thermal management system for selectively thermally coupling the heat sink exchanger with the heat source exchanger.

Description

FIELD[0001]The present subject matter relates generally to a thermal management system for an aircraft including an electric propulsion engine and a method of controlling the same.BACKGROUND[0002]A conventional commercial aircraft generally includes a fuselage, a pair of wings, and a propulsion system that provides thrust. The propulsion system typically includes at least two aircraft engines, such as turbofan jet engines. Each turbofan jet engine is mounted to a respective one of the wings of the aircraft, such as suspended position beneath the wing. More recent aircraft, however, have proposed electric or hybrid-electric propulsion systems including electric propulsion engines, such as electric fans.[0003]Regardless of the propulsion system utilized, various systems of the aircraft may generate a relatively large amount of heat during certain operating conditions of the aircraft. For example, an environmental control system of the aircraft may generate a varying amount of heat bas...
