Abstract:
A method of preventing standing waves in an installed gas turbine having a fan, having a fan speed, and a compressor, having a compressor speed, includes correcting the fan and compressor speeds for temperature and monitoring the corrected speeds to prevent them from converging, or becoming the same value. In addition, a computer implemented monitoring and adjusting program may monitor a position of an aircraft on a ACTFS plot and make adjustments to avoid intercepting a surge line by changing the speed of the plane, one or both of the fan or compressor speeds or by changing altitude. An aircraft may form a standing wave when crossing or operating on a surge line of an ACTFS plot and this condition should be avoided which may require high data rate monitoring and control logic.

Claim (Index 9):
A method of preventing standing waves in an installed gas turbine comprising the steps of:\n providing a vehicle having a gas turbine; wherein the gas turbine comprises a fan having a fan speed and a compressor having a compressor speed; providing a fan sensor to measure the fan speed and a compressor sensor to measure the compressor speed; providing a fan temperature sensor for measuring a fan temperature and a compressor temperature sensor for measuring a compressor temperature;\n providing a computer implemented monitoring and adjustment \n program that is executed by a processor;\n inputting the fan speed, the fan temperature, and the compressor speed and the compressor temperature into the computer implemented monitoring and adjustment program; \n calculating a correlated fan speed and a correlated compressor speed, \n wherein the calculating of the correlated fan speed and the correlated compressor speed includes adjusting the fan speed for the fan temperature and adjusting the compressor speed for compressor temperature; \n calculating an acoustical critical turbo system frequency (ACTSF) \n value that is a resonate frequency of at least a portion of the installed gas turbine;\n creating an ACTSF plot having a plurality of points along an ACTSF line thereon; \n determining a current altitude or said vehicle and a current speed value of said compressor;\n determining an altitude rate of change and a compressor speed rate of change; \n determining an intersect with at least one of the plurality of points on the ACTSF line corresponding to the ACTSF; \n wherein the ACTSF plot comprises an altitude ordinate and a speed abscissa with the ACTSF line; and \n avoiding an intercept with the ACTSF line by changing one of the altitude rate of change, the compressor speed rate of change, the correlated fan speed, or the correlated compressor speed, thereby prevent standing waves in the gas turbine.
