Method and Apparatus for Spectroscopic Measurements in the Combustion Zone of a Gas Turbine Engine
First Claim
1. A method of measuring combustion properties within a combustion zone of a gas turbine engine, the combustion zone being defined between an inner and an outer casting, the method comprising:
- a) transmitting a beam from a transmit optic optically coupled to a port in the outer casing off a portion of the inner casing; and
b) receiving a portion of the beam reflected off the portion of the inner casing with a receiving optic optically coupled to a port in the outer casing.

Abstract
A method for measuring combustion parameters within a combustion zone of a gas turbine engine, the combustion zone being defined between an inner and outer casing. The method comprises transmitting a beam from a transmit optic optically coupled to a bore in the outer casing off a portion of the inner casing and receiving a portion of the beam reflected off the inner casing with a receiving optic optically coupled to a bore in the outer casing. An apparatus for practicing the method comprises a laser generating a beam and a transmitting/receiving optics pair, the transmitting/receiving optics pair being configured for operative association with a port in an outer casing of a gas turbine engine, whereby the transmitting/receiving optics are in optical communication by reflecting the beam off a portion of an inner casing.

11. A gas turbine engine comprising:
-
a combustion zone between an inner and outer casing; a port in the outer casing operatively associated with the combustion chamber substantially opposite a portion of the inner casing; and a transmitting and receiving pair of optics optically coupled with the port, the transmitting and receiving pair of optics being configured so that the transmitting optic transmits a beam off the portion of the inner casing and the receiving optic receives at least a portion of the beam reflected off the portion of the inner casing.
