Abstract
An air cycle system for a gas turbine engine includes a compressor, a turbine and a heat exchanger fluidly connected between the compressor and the turbine. A fluid source communicates a fluid through the heat exchanger. The heat exchanger exchanges heat between the fluid and an airflow communicated through the heat exchanger from the compressor to provide a conditioned airflow.
Claims18
An air cycle system for a gas turbine engine, comprising:
- a compressor;
- a turbine;
- a heat exchanger fluidly connected between said compressor and said turbine;
- and
- a fluid source that communicates a fluid through said heat exchanger, wherein said heat exchanger exchanges heat between said fluid and an airflow communicated through said heat exchanger from said compressor to provide a conditioned airflow.
2 more elements
A gas turbine engine, comprising:
- a compressor section, a combustor section and a turbine section;
- a bleed port disposed at a portion of the gas turbine engine;
- and
- an air cycle system that selectively receives a bleed airflow from said bleed port, wherein said air cycle system includes a compressor, a turbine and a heat exchanger fluidly connected between said compressor and said turbine, and wherein a first portion of a conditioned airflow is communicated from said heat exchanger to said turbine and a second portion of said conditioned airflow is communicated from said heat exchanger to a high pressure location of at least one of said compressor section, said combustor section and said turbine section.
1 more element
A method of communicating conditioned airflow to various locations of a gas turbine engine, comprising the steps of:
- communicating a bleed airflow from the gas turbine engine to an air cycle system;
- compressing the bleed airflow to provide a compressed airflow;
- cooling the compressed airflow to provide a conditioned airflow;
- and
- communicating a first portion of the conditioned airflow to a turbine of the air cycle system and communicating a second portion of the conditioned airflow to a high pressure location of the gas turbine engine.
