Abstract
A dual cycle vectored thrust engine has a flow control valve for changing the cycle from a pure jet for supersonic operation to by-pass cycle for vertical take-off. The valve has two separate inlets, two separate outlets and passageways within the valve which provide flow communication between the inlets and the outlets, one part of the valve being rotatable relative to the other to change the direction of flow through one of the inlets from communication with one of the outlets to communication with the other of the outlets. The passageways leading to one of the outlets are shaped to turn the flow through up to 180.degree. to enable the flow to be passed to front vectorable nozzles upstream of the valve.
