Abstract

Aspects of the disclosure are directed to a system associated with an engine of an aircraft, comprising: a deoiler configured to receive a mixture of air and oil at an input of the deoiler and separate the air from the oil, and a baffle coupled to the input of the deoiler and configured to prevent debris that is larger than a threshold from entering the deoiler.

First claim

What is claimed is:

1. An engine comprising:
a deoiler configured to receive a mixture of air and oil at an input of the deoiler and separate the air from the oil;
a baffle stationarily coupled to the input of the deoiler and configured to prevent debris that is larger than a threshold from entering the deoiler; and
a shaft coupled to the deoiler that is configured to rotate the deoiler, the deoiler being a centrifugal deoiler,
whereby the baffle is stationary when the deoiler rotates,
wherein the baffle comprises a plurality of pores, and wherein a dimension of each of the pores is less than the threshold,
wherein a compressor section, a combustor section, a turbine section, and an augmentor section are sequentially aligned along an axial centerline between an engine airflow inlet and an engine airflow exhaust,
wherein the augmentor section includes a first duct case, a second duct case, and one or more vanes.

2. The engine of claim 1 , wherein the deoiler is configured to provide the separated oil to an oil tank.

3. The engine of claim 1 , wherein the deoiler is configured to provide the separated air to an overboard vent system.

4. The engine of claim 1 , further comprising:
a plurality of bearings configured to support the shaft.

5. The engine of claim 1 , wherein the deoiler comprises a porous or mesh material that is configured to capture the mixture of air and oil.

6. The engine of claim 1 , wherein the dimension of each of the pores ensures against a bearing distress event.
