Abstract:
1. A system for determining sensor locations in a gas turbine engine, said system comprising: a turbine rear frame comprising a radially inner surface, a radially outer surface and a plurality of circumferentially-spaced struts extending between said inner and outer surfaces such that a strut sector is defined between each pair of circumferentially-spaced struts; a plurality of fuel nozzles, each of said plurality of fuel nozzles is aligned with one of said strut sectors, wherein one of said plurality of fuel nozzles is a primary index nozzle; a plurality of operating parameter sensors; and a controller comprising a processor, said controller configured to determine a position of each of said plurality of sensors relative to one of said plurality of nozzles by calculating a positioning angle corresponding to each of said plurality of sensors.
