ABSTRACT:
For improved thrust responsiveness and smooth transition of the various zones of an augmentor of an augmented jet engine powered aircraft, the time to prefill the fuel manifolds of the zones are calculated from preselected parameters so as to be on line upon light-off. The throttle lever signal is rate limited so that the preascertained manifold volume of each zone divided by the zone filling fuel flow produces a signal indicative of the time to open the normal fuel fill valve to prefill the manifold at the proper time and in the right sequence using a rate limited throttle lever signal.
