Abstract
A control circuit arrangement for a gas turbine engine has first and second identical control circuits which are responsive to groups of input signals to provide nominally identical first and second output signals. It is arranged that input signals to the first control circuit are nominally identical with corresponding input signals to the second control circuit. Means are provided, responsive to malfunction of either one of the first and second control circuits, to render the malfunctioning circuit inoperative and to render the other of the control circuits operative. A third control circuit is responsive to at least one pair of corresponding input signals to the first and second circuits, to provide a third output signal to the engine. The first, second and third output signals do not control the engine reheat system, and the arrangement may include a fourth control circuit for controlling this reheat system.
