Abstract

A debris monitor sensor system according to one disclosed non-limiting embodiment of the present disclosure includes a first passage disposed substantially linearly along a flow path, the first passage includes a sensor passage section. A second passage splits from the first passage and is offset from the flow path. An oil debris monitor is in communication with the sensor passage section.

First claim

1 . A debris monitor sensor system comprising:
a first passage disposed along a flow path, said first passage includes a sensor passage section; a second passage that splits from said first passage and is offset from said flow path; and an oil debris monitor in communication with said sensor passage section.

2 . The system as recited in claim 1 , wherein said second passage splits from said first passage at a first angle with respect to said axis, said first passage disposed substantially linearly along said flow path.

3 . The system as recited in claim 2 , wherein said first angle is about 90 degrees with respect to said axis.

4 . The system as recited in claim 2 , wherein said first angle is greater than 90 degrees with respect to said axis.

5 . The system as recited in claim 2 , wherein said first angle is greater than 45 degrees with respect to said axis.

6 . The system as recited in claim 2 , wherein said second passage rejoins said first passage downstream of said sensor passage section.

7 . The system as recited in claim 6 , wherein said second passage rejoins said first passage downstream of said sensor passage section at a second angle.

8 . The system as recited in claim 7 , wherein said second angle is about 20-45 degrees with respect to said axis.

9 . The system as recited in claim 1 , wherein said second passage defines a diameter generally equal to said first passage.

10 . The system as recited in claim 1 , wherein said second passage defines a diameter smaller than said first passage.

11 . The system as recited in claim 1 , wherein said first passage and said second passage communicate separately with an oil system component.

12 . The system as recited in claim 11 , wherein said oil system component is a deaerator.

13 . The system as recited in claim 1 , wherein said first passage and said second passage are linearly offset, said first passage having a first gravitational potential and said second passage having a second gravitation potential, said first gravitational potential different than said second gravitation potential

14 . A debris monitor sensor system for a gas turbine engine comprising;
a first passage along an axis, said first passage includes a sensor passage section; a second passage that splits from said first passage at a first angle and rejoins said first passage at a second angle; and an oil debris monitor in communication with said sensor passage section.

15 . The system as recited in claim 14 , wherein said first angle is greater than 45 degrees with respect to said axis and said second passage is less than 45 degrees with respect to said second passage.

16 . The system as recited in claim 14 , wherein said first angle is about 90 degrees with respect to said axis and said second passage is less than 45 degrees with respect to said second passage.

17 . The system as recited in claim 14 , wherein said first angle is greater than 90 degrees with respect to said axis and said second passage is less than 45 degrees with respect to said second passage.

18 . A method of debris monitoring for a gas turbine engine, comprising:
splitting and rejoining a second passage from a first passage around a sensor passage section in the first passage to direct debris through the sensor passage section.

19 . The method as recited in claim 18 , further comprising:
splitting the second passage from the first passage at a first angle of about 90 degrees.

20 . The method as recited in claim 18 , further comprising:
splitting the second passage from the first passage at a first angle greater than 90 degrees.
