<p>The control system contains a fluidic oscillator, the oscillation frequency of which is a function of the fuel flow ratio through the oscillator. It also has a fluidic control throttle, with a fluidic impedance, controlled by the rate, at which the fuel is fed to one of its control inlets. There is a control to adjust the rate, dependent upon the oscillation frequency of the oscillator, and one or more requirement values of the drive. The oscillator and the throttle are switched in series, so that during operation, all the fuel flowing to the drive passes through them. The oscillator is formed as a bi-stable adhesive unit, with two connected control apertures.</p> |
