    • A method is for determining the angular positions of multiple compressor guide vanes. The method includes measuring the positions of at least two points on the circumference of the actuating ring, via at least two linear position sensors fixed on the compressor casing, and pointing at the actuating ring vertically at a time when the actuating ring deviates from its original position where the ring center coincides with the casing center; calculating the ring center offset based on the measured positions of the at least two points and the radius of the actuating ring; measuring the angle of one of the multiple guide vanes at the same time when measuring the positions of the at least two points; and calculating the angles of the multiple guide vanes based on the ring center offset and the angle of the guide vane. An actuation apparatus for multiple compressor guide vanes is included.

    • The invention relates to a method for controlling a turbine engine (5) which includes a compressor (8), a combustion chamber (9), first and second turbines (10, 12), a first rotary shaft (11) rotatably secured to said compressor and to said first turbine, a second rotary shaft (13) to which the second turbine is rotatably secured, said second rotary shaft being freely rotatable relative to the first rotary shaft, and a controller (15) for controlling the fuel supply to the combustion chamber. Said controller interrupts the fuel supply to the combustion chamber if a speed of rotation (N2) of said second rotary shaft exceeds a maximum threshold (N2imax) which varies according to at least one indicative physical parameter associated with a mechanical power extracted from combustion gases in the second turbine.
