Abstract

The invention relates to the field of aero-engine nozzles, in particular to a two-dimensional vector convergent-divergent nozzle capable of achieving pitching and yawing. The two-dimensional vector convergent-divergent nozzle comprises a barrel, two pitching adjusting sheets, two yawing adjusting sheets, four sealing sheets, first actuating cylinders, first pulling rods, second actuating cylinders and second pulling rods. The outer side face of each pitching adjusting sheet is connected with the corresponding first pulling rod and the corresponding first actuating cylinder so that the pitching adjusting sheet can rotate in the pitching direction. The outer side face of each yawing adjusting sheet is connected with the corresponding second pulling rod and the corresponding second actuating cylinder so that the yawing adjusting sheet can rotate in the yawing direction. Sealing sheets are located between the pitching adjusting sheets and the yawing adjusting sheets. The two-dimensional vector convergent-divergent nozzle capable of achieving pitching and yawing is simple in structure; deflecting, converging and diverging in the pitching and yawing directions are achieved through deformation combination of the adjusting sheets on the four sides; good aerodynamic performance is also achieved, the control law is simple, and the reliability is high.

Description

technical field [0001] The invention relates to the field of aero-engine nozzles, in particular to a binary vector diverging nozzle capable of pitching and yawing. Background technique [0002] The binary vector diverging nozzle is one of the types of nozzles used in traditional aero-engines, and it has excellent stealth performance compared to other nozzles. Due to structural limitations, the currently used binary vector retractable nozzle can only be retracted and deflected in the pitch direction, thus restricting the maneuverability of the aircraft. In order to meet the diversified needs of future aircraft, it is necessary to design a binary vector retractable nozzle with simple structure, few moving parts, and capable of pitching and yawing. Contents of the invention [0003] The purpose of the present invention is to provide a binary vector retractable nozzle that can realize pitch and yaw, so as to solve the problem that the current binary vector retractable nozzle ...
