20100204931 | CONTINUOUS PERFORMANCE ANALYSIS SYSTEM AND METHOD - A system and method of conducting a continuous performance analysis for a system includes collecting transient performance data for a first parameter of the system and a second parameter of the system. Transfer functions are applied to the transient performance data for at least one of the first and second parameters to thereby generate phase compensated performance data representative of a steady state relationship between the first and second parameter. For each phase compensated performance datum, an estimate of the first parameter is calculated at a predetermined value of the second parameter using the phase compensated performance datum and a previously stored performance characteristic curve representative of the steady state relationship between the first and second parameters in a deterioration model extrapolation method. A very efficient binning method is used for storing phase compensated performance data and converting them into steady state performance characteristic curves of any non-linear shape. | 08-12-2010 |
20130019606 | GAS TURBINE ENGINE SPEED CONTROL SYSTEM AND METHOD DURING MAXIMUM FUEL FLOW - Methods and apparatus are provided for selectively controlling the rotational speed of a gas turbine engine that drives a load compressor having movable inlet guide vanes and that is coupled to receive fuel at a fuel flow rate up to a maximum fuel flow rate. The rotational speed of the gas turbine engine, and the fuel flow rate to the gas turbine engine, are both sensed. If the sensed rotational speed of the gas turbine engine is less than a predetermined value and the sensed fuel flow rate to the gas turbine engine equals or exceeds the maximum fuel flow rate, the position of the inlet guide vanes is controlled to reduce load compressor mechanical load on the gas turbine engine. | 01-24-2013 |

20140236534 | SYSTEM AND METHOD FOR CONTINUOUS PERFORMANCE ANALYSIS OF SYSTEMS THAT EXHIBIT VARIABLE PERFORMANCE CHARACTERISTICS AT DIFFERENT OPERATING CONDITIONS - A system and method for translating performance characteristics of a system from one system condition to another system condition includes sensing, at a current system condition, a first system performance parameter and a second system performance parameter. The first and second system performance parameters correspond to a measured performance characteristic value of the system. A first reference performance datum associated with the first and second system performance parameters at the current system condition, and a second reference performance datum associated with the first and second system performance parameters at a selected reference system condition are both retrieved from a memory. A difference between the first and second reference performance data is calculated to generate a translation value. The measured performance characteristic value of the system is then translated an amount equal to the data translation value, whereby a corrected performance characteristic value at the selected reference system condition is generated. | 08-21-2014 |
