Abstract:
A method for controlling a turbine engine containing first and second coaxial rotatable shafts, a first row of blades connected to the first shaft and a second row of blades connected to the second shaft downstream of the first row of blades, the method comprising the steps of:i) sensing the rotational speed of the first row of blades;ii) sensing the rotational speed of the second row of blades;iii) processing the signals received from the sensing steps of i) and ii); andiv) determining the shutting of fuel flow to the engine if the signal of one of i) and ii) indicates that the speed of one of the first row of blades and the second row of blades decelerates below a minimum required level relative to the speed of the other of the first and second row of blades.
