Open the CIPO recordAbstract From the Canadian patent
An invention is disclosed in which a signal indicating a rate of fuel flow desired for a gas turbine engine is bounded between limits imposed by maximaland minimal-fuel rates allowed under the current operating conditions of the engine and between limits imposed by maximal- and minimal-accelarations allowed under the same operating conditions. The fuel rate limits are constantly modified by feedback information about the actual acceleration experienced by the engine. this feedback information about acceleration is obtained without directly measuring acceleration itself.
