Abstract
A method for determining the presence of a particle while actively calculating and monitoring oil debris monitor phase angle in an oil system including collecting I and Q channel data from an oil debris monitor sensor, performing a fast Fourier transform on the I and Q channel data, extracting a shape from the fast Fourier transform, and determining whether a particle is present from the shape.
Claims20
A method for determining the presence of a particle while actively calculating and monitoring oil debris monitor phase angle in an oil system, comprising:
- collecting I and Q channel data from an oil debris monitor sensor;
- performing a fast Fourier transform on the I and Q channel data;
- extracting a shape from the fast Fourier transform;
- and
- determining whether a particle is present from the shape.
An oil system for a gas turbine engine, comprising:
- an oil flow path;
- an in-line oil debris monitor sensor;
- and
- a control system in communication with the in-line oil debris monitor sensor to determine whether a particle is present from identification of a bow shape in a fast Fourier transform of I and Q channel data from the in-line oil debris monitor sensor.
