Method of controlling engine performance

Abstract

The present invention provides a method of controlling engine performance that includes obtaining at least one optical wavelength-dependent measurement from at least one combustion event in at least one combustion chamber. The method further includes analyzing the optical wavelength-dependent measurement for determining adjustments to the at least one combustion event. Additionally, the method includes adjusting the at least one combustion event or at least a next combustion event by changing at least one physical parameter, at least one constituent parameter, or at least one physical parameter and at least one constituent parameter to control the engine performance, where the physical parameter includes adjusting a turbine blade angle using a vane-adjust actuator in response to a signal from a controller. The engine can include steady-flow engines or periodic flow engines, and the engine performance can be selected by an engine user.

What is claimed is: 
     
         1 . A method of controlling engine performance comprising:
 a. obtaining at least one optical wavelength-dependent measurement from at least one combustion event in at least one combustion chamber of an engine;   b. analyzing said at least one optical wavelength-dependent measurement for determining adjustments to said at least one combustion event; and   c. adjusting said at least one combustion event or at least a next combustion event by changing at least one physical parameter, at least one constituent parameter, or at least one physical parameter and at least one constituent parameter to control said engine performance, wherein said physical parameter comprises adjusting a turbine blade angle using a vane-adjust actuator in response to a signal from a controller.
