Abstract

An airplane is provided. The airplane includes a compressing device including a turbine and a compressor. The turbine includes first and second inlets and provides energy by expanding one or more mediums. The first inlet is receives a first medium of the one or more mediums. The second inlet receives a second medium of the one or more mediums. The compressor receives a first energy derived from the first and second mediums being expanded across the turbine during a first mode of the compressing device, receives a second energy derived from the first medium being expanded across the turbine during a second mode of the compressing device, and compresses the second medium in accordance with the first mode or the second mode.

First claim

What is claimed is:

1. A compressing device, comprising:
a turbine comprising a first inlet and a second inlet and configured to provide energy by expanding one or more mediums,
wherein the first inlet is configured to receive a first medium of the one or more mediums, and
wherein the second inlet is configured to receive a second medium of the one or more mediums;
a compressor configured to:
receive a first energy derived from the first and second mediums being expanded across the turbine during a first mode of the compressing device,
receive a second energy derived from the first medium being expanded across the turbine during a second mode of the compressing device, and
compress the second medium in accordance with the first mode or the second mode;

a fan configured to receive the first energy during the first mode and the second energy during the second mode; and
a power turbine configured to provide a third energy by expanding a third medium of the one or more mediums in accordance with the first mode or the second mode,
wherein the compressor is configured to receive the third energy as a power assist from the third medium expanded across the power turbine;
wherein the first medium and the second medium are mixed at the turbine during the first mode at a first mixing point, and wherein the first medium and the second medium are mixed downstream of the turbine during the second mode at a second mixing point.

2. The compressing device of claim 1 , wherein the first medium and the second medium are mixed at the turbine during the first mode.

3. The compressing device of claim 1 , wherein the first medium and the second medium are mixed downstream of the turbine during the second mode.

4. The compressing device of claim 1 , wherein the first medium is bleed air and the second medium is fresh air.

5. An environmental control system of an aircraft comprising the compressing device of claim 1 .

6. The compressing device of claim 1 , comprising:
a valve controlling whether a flow of the third medium bypasses the power turbine in accordance with the first mode or second mode.
