METHOD FOR DETERMINING CIRCUMFERENTIAL SENSOR POSITIONING

摘要

A method for positioning sensors about a sensor ring includes the steps of assigning each sensor in a plurality of sensors a sensor number selected from a set of sensor numbers, where the set of sensor numbers is a whole number in the range of 0 to N, and where N is the total number of sensors in said plurality of sensors minus one, disposing a first sensor at a circumferential angular position zero on the sensor ring, and disposing each sensor in the plurality of sensors at a circumferential angular position about the sensor ring, wherein the circumferential angular position is defined by an offset from a circumferential angular position zero and the offset is equal to a base arc length between sensors multiplied by the sensor number of the sensor plus a base offset arc length multiplied by the sensor number of the sensor.

1. A gas turbine engine comprising:
a compressor section; a combustor fluidly connected to the compressor section via a core flow path, the combustor including a plurality of fuel nozzles and the plurality of fuel nozzles are disposed evenly circumferentially about the combustor; a turbine section fluidly connected to the combustor section via the core flow path; a plurality of sensors disposed circumferentially about the core flow path; each sensor in said plurality of sensors has a sensor number selected from a set of sensor numbers, where the set of sensor numbers is a whole number in the range of 0 to N, where N is the total number of sensors in said plurality of sensors minus one; and each sensor of said plurality of sensors is offset circumferentially from a circumferential angular position zero wherein the offset is equal to a base arc length between sensors multiplied by the sensor number of the sensor plus a base offset arc length multiplied by the sensor number of the sensor.
