ABSTRACT:
Apparatus for controlling the flow of exhaust gases between a plurality of rocket storage chambers, launch tubes or the like (herein referred to as chambers), and a common manifold for ducting rocket exhaust gases to a discharging location comprises a plurality of chamber-to-manifold flow transition sections, each having disposed within vertical portions thereof a pair of flow control doors. The flow control doors, pivotably mounted at upper portions in opposing relationship, are configured and counterbalanced to hang, in static conditions and under the force of gravity alone, in a fully or nearly fully closed condition. Alternatively, un-counterbalanced doors may be configured to hang, under static conditions, at least slightly inwardly inclined towards the vertical axis of the transition portion in which they are hung. During a rocket firing, manifold pressure causes doors in the transition sections, other than those through which a rocket is firing, to close and remain closed, thereby preventing circulation of rocket exhaust gases into non-firing rocket chambers. Flow control doors associated with firing rockets are caused to pivot towards a fully open condition by unbalanced moments acting thereon.
