Abstract
1276965 Deflecting propulsion jets MESSERSCHMITT-BOLKOW-BLOHM GmbH 18 Nov 1970 [10 Dec 1969] 54881/70 Heading B7G [Also in Division F1] The invention relates to a variable area jet propulsion nozzle which may also be adjusted to vary the direction of thrust of the jet, the nozzle being of polygonal outlet section, there being angularly movable flap members pivotally mounted at the end of the nozzle and movable between convergent and divergent positions, double-panelled corner pieces being provided between the ends of adjacent flap members. In Figs. 1 and 2 the nozzle 1 is of square section and angularly movable flap members 2, 3, 4, 5 are pivotally mounted at the downstream ends of the walls forming the nozzle, each flap being movable independently by an actuator, not shown. The flaps are each defined by spaced inner and outer walls of trapezoidal form. Corner pieces such as 9 are disposed between the ends of adjacent flaps, each corner piece comprising two sector shaped panels 19, 29 pivotally connected by a hinge at the axis 10 and the panels engaging between the walls of the flap members so that as the flap members move to the convergent position shown in Fig. 2 the panels 19, 29 of the corner pieces move further into the spaces between the walls of the flap members and the angle between the panels increases. The flap members may be moved so that the jet stream is deflected either laterally as shown in Fig. 4 or in the vertical direction.
