Abstract

An inertial inlet particle separator system for a vehicle engine is provided. A separator assembly and collector assembly are coupled to the scavenge flow path and configured to receive the scavenge air. The collector inlet has a throat defining a cumulative throat area at each position along the throat length from the first throat end to the second throat end. The collector body defines a cross-sectional area associated with each position along the throat length between the first throat end and the second throat end. The collector outlet is coupled to the collector body such that scavenge air flows into the collector inlet, through the collector body, and out through the collector outlet. At a first position between the first throat end and the second throat end, the respective cross-sectional area of the collector body is greater than or equal to the respective cumulative throat area.

First claim

What is claimed is:

1. An inertial inlet particle separator system for a vehicle engine, comprising:
a separator assembly defining a fluid inlet for receiving inlet air, the separator assembly further including a scavenge flow path and an engine flow path and configured to separate the inlet air into scavenge air and engine air such that the scavenge air is directed into the scavenge flow path and the engine air is directed into the engine flow path; and
a collector assembly coupled to the scavenge flow path and configured to receive the scavenge air, the collector assembly comprising
a collector inlet coupled to the scavenge flow path, the collector inlet having a throat extending from a first throat end to a second throat end to define a throat length, wherein the throat further defines a cumulative throat area at each position along the throat length from the first throat end to the second throat end,
wherein the collector assembly includes a first partition, a second partition, a third partition, and a fourth partition that collectively divide the throat into a first throat portion extending between the first and second partitions, a second throat portion extending between the second and third partitions, a third throat portion extending between the third and fourth partitions, and a fourth throat portion extending between the fourth and first partitions;
a collector body coupled to the collector inlet along the throat length, wherein the collector body defines a cross-sectional area associated with each position along the throat length between the first throat end and the second throat end,
wherein the collector body includes a first body portion along the first throat portion, a second body portion along the second throat portion, a third body portion along the third throat portion, and a fourth body portion along the fourth throat portion,
wherein the collector assembly is a circumferential collector assembly with a circumference, and wherein each of the first and second throat portions extends approximately 90° of the circumference; and
a collector outlet coupled to the collector body such that scavenge air flows into the collector inlet, through the collector body, and out through the collector outlet,
wherein the collector outlet includes a first outlet portion and a second outlet portion, and wherein the first and second body portions direct air into the first outlet portion and the third and fourth body portions direct air into the second outlet portions, and
wherein, at a first position between the first throat end and the second throat end, the respective cross-sectional area of the collector body is greater than or equal to the respective cumulative throat area.

2. The inertial inlet particle separator system of claim 1 , wherein, at all positions between the first throat end and the first position, the respective cross-sectional area of the collector body is greater than or equal to the respective cumulative throat area.

3. The inertial inlet particle separator system of claim 1 , wherein, at all positions between the first throat end and the second throat end, respective ratios between respective cross-sectional areas of the collector body and respective cumulative throat areas are generally constant.

4. The inertial inlet particle separator system of claim 1 , wherein, at all positions between the first throat end and the second throat end, the respective cross-sectional area of the collector body is greater than or equal to the respective cumulative throat area.

5. The inertial inlet particle separator system of claim 1 , wherein the first and second outlet portions are separated from one another along the circumference by approximately 180°.

6. The inertial inlet particle separator system of claim 1 , wherein the collector assembly is at least partially a scroll that surrounds the separator assembly.
