<p>A fuel control system (11) for a gas turbine (10) of the acceleration based, closed loop kind, wherein the fuel flow (Wf) to the engine is controlled as a function of the difference between an actual speed signal (Nh) and a demanded speed signal (Nd) which itself is proportional to the time integral of a demanded acceleration signal (Aa);
<??>According to this invention, there is provided a stall condition detector means (46, 40) which generates a stall factor (Sf) indicative of the degree of stall the engine is experiencing and causes reduction of the engine acceleration as a function of said stall factor;
<??>For use in fuel control systems for gas turbine engines.</p> |
