Abstract

1515302 Automatic control HAWKER SIDDELEY DYNAMICS ENG Ltd 9 June 1973 [25 April 1974] 18198/74 Headings G3N and G3R [ Also in Divisions F4 and G 1] Fuel flow to a combustion chamber is controlled in response to the difference, obtained at 33, between the actual air flow to the chamber and a nominal value, the difference being applied via a ratio controlling amplifier 35 to a comparator 34, the other input to which is a nominal value for fuel flow. The output of 34 constitutes a desired value for a fuel flow control loop 32, 36, 37.
