Abstract
A probe that includes both a temperature transducer and a pressure sensing port is adapted to be mounted upon and extend into the intake housing of a gas turbine engine. The probe is operative to provide air temperature and pressure data to an engine controller for the gas turbine engine.
Claims22
A probe for a gas turbine engine comprising:
- a probe body having a central axis, said probe body adapted to extend into a gas turbine engine housing;
- a first bore extending into said probe body parallel to said central probe axis, said first bore having a closed end;
- a second bore extending into said probe body parallel to said central probe axis and communicating with a gas inlet port formed in said probe body, said second bore adapted to cooperate with a pressure sensor;
- an access bore extending into said probe body from an end of said probe body opposite from said closed end of said first bore, said access bore intersecting said first bore;
- a temperature transducer disposed within said closed end of said first bore, said temperature transducer operable to change an electrical parameter in proportion to a change in temperature;
- and
- at least one electrical conducting path connected to said temperature transducer and extending though a portion of said first bore and said access bore to said end of said probe body.

A probe for a gas turbine engine comprising:
- a probe body that is adapted to extend into a gas turbine engine housing, said probe body having a non-circular cross sectional shape that corresponds to the shape of an aperture formed through a gas turbine engine housing, said aperture receiving said probe body and co-operating therewith to orient said probe body within said gas turbine engine housing such that a gas inlet port formed in said probe body is positioned in a predetermined direction relative to said gas turbine engine housing;
- a first bore extending into said probe body;
- a second bore extending into said probe body and communicating with a gas inlet port formed in said probe body, said second bore adapted to cooperate with a pressure sensor;
- and
- a temperature transducer disposed within said first bore.

A gas turbine engine control unit comprising:
- a control unit housing adapted to be mounted upon a gas turbine engine, said control unit housing having an aperture formed therethrough;
- a plurality of engine control components mounted within said gas turbine engine control unit housing, said control components operational to control a gas turbine engine;
- a probe body mounted within said control unit housing and extending through said housing aperture, said probe body adapted to extend into a gas turbine engine housing;
- a first bore extending into said probe body;
- a second bore extending into said probe body and communicating with a gas inlet port formed in said probe body;
- a pressure sensor disposed within said control unit housing and cooperating with said second bore, said pressure sensor electrically connected to said engine control components and operative to supply a signal that is proportional to the gas pressure within said second bore to engine control components;
- and
- a temperature transducer disposed within said first bore, said temperature sensor electrically connected to said engine control components and operative to supply a signal that is proportional to the gas temperature within the gas turbine engine to said engine control components.
