Abstract: A JET ENGINE FOR BOTH DIRECTED LIFT AND FORWARD PROPULSION OF AN AIRCRAFT HAS A GAS GENERATOR DISCHARGING INTO AN EXHAUST DUCT WHICH HAS A REARWARDLY DIRECT VARIABLE AREA NOZZLE AND DOWNWARDLY DIRECTLY VARIABLE LIFT NOZZLE. THE PROPULSION NOZZLE IS OF A TYPE WHICH CAN BE SUBSTANTIALLY ENTIRELY CLOSED. LIFT NOZZLE INCLUDES MOVABLE VANES AT ITS FORWARD AND REAR EDGES WHICH MAY BE SWUNG TO VARY THE DIRECTION OF THRUST FROM PARTLY FORWARD TO REARWARD AND IN WHICH THE FORWARD VANE MAY BE SWUNG REARWARDLY TO THROTTLE THE OUTLET, AND FINALLY INTO CONTACT WITH THE REAR VANE TO CLOSE THE LIFT NOZZLE ENTIRELY. IN TRANSITION BETWEEN LIFT AND CRUISE CONDITIONS, THE AREAS OF THE TWO NOZZLES ARE VARIED INVERSELY SO AS TO MAINTAIN SUBSTANTIALLY CONSTANT TURBINE SPEED AND BACK PRESSURE AND SUBSTANTIALLY CONSTANT TOTAL THRUST.
