Abstract
A turbine engine may occasionally be required to operate momentarily at an overtemperature condition which, provided it does not exceed a predetermined maximum temperature and time duration, is known to be harmless. A temperature read-out device attached to an engine operating under such conditions would measure this harmless overtemperature transient, indicate an overtemperature state, and display a warning. The circuitry of the present invention monitors a signal representing engine temperature, and beginning at the start of the harmless overtemperature transient, and generates an opposing compensating signal for a predetermined period of time. The opposing compensating signal is combined with the signal representing engine temperature and the resultant signal, is applied to the temperature readout device so that the signal representing engine temperature is reduced below the level which would cause an overtemperature condition to be indicated on the temperature readout device.
