Problems solved by technology

Diverting higher pressure and higher temperature air from the engine than needed reduces engine efficiency
In addition, the heat exchangers used to cool the air drawn from the engines add to the overall aircraft weight, which also reduces the aircraft's fuel efficiency

Embodiment Construction

[0023] Various embodiments of the present disclosure relate to engine bleed air control for a gas turbine engine. Embodiments of the present disclosure may be applied to any turbomachinery used to divert compressed air for auxiliary use. For example, the gas turbine engine is a rotary combustion turbine engine built around a power core consisting of a compressor, combustor and turbine connected to an upstream inlet Arranged in flow series with the downstream exhaust port. The compressor compresses air from the inlet, which is mixed with fuel in the combustor and ignited to generate hot combustion gases. The turbine extracts energy from the expanding combustion gases and drives the compressor via a common shaft. Energy is delivered in the shaft as rotational energy, out of the exhaust as reactive thrust, or both. Compressed air can be extracted from each stage as extraction air.

Abstract

An engine bleed control system for a gas turbine engine of an aircraft is provided. The engine bleed control system includes an engine bleed tap coupled to a fan-air source or a compressor source of a lower pressure compressor section before a highest pressure compressor section of the gas turbine engine and a motorized compressor in fluid communication with the engine bleed tap. The engine bleed control system also includes a controller operable to selectively drive the motorized compressor to boost a bleed air pressure from the engine bleed tap as pressure augmented bleed air and control delivery of the pressure augmented bleed air to an aircraft use.

Description

technical field [0001] The present disclosure relates to gas turbine engines, and more particularly, to engine bleed air systems with motorized compressors. Background technique [0002] Gas turbine engines are used in many applications, one of which is to provide thrust for aircraft. Compressed air is usually split at a high pressure point near the combustor for ancillary purposes such as aircraft environmental control. However, this high pressure air is generally hotter than air that can be safely supported by the ductwork and delivered to the aircraft. Thus, a precooler or heat exchanger is used to cool hot engine bled air and is typically located near the engine so that overheated air is not ducted over the aircraft wing for safety. Diversion of higher pressure and higher temperature air from the engine than is required reduces engine efficiency. In addition, the heat exchangers used to cool the air drawn from the engines add to the overall aircraft weight, which also...
