Engine bleed system with motorized compressor

This invention describes a system for an aircraft engine that takes air from a relatively cool, low-pressure part of the engine's fan section. This air is then fed into an electrically powered compressor to boost its pressure. The higher-pressure air is then supplied to the aircraft, for example, to its environmental control system.

Why it matters: Since 2016, the aerospace industry's focus on "more electric aircraft" has accelerated, making electrically driven compressors for bleed air systems more attractive for efficiency and reduced engine load.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedMotorized compressor, controller, aircraft integration.
