Binary vectoring nozzle capable of achieving rolling function

Abstract

The invention belongs to the technical field of aero-engine design, and particularly relates to a binary vectoring nozzle capable of achieving a rolling function. The binary vectoring nozzle comprisesa round-to-square cylinder, two side walls symmetrically arranged at the rear end of the round-to-square cylinder in parallel, two convergence adjusting sheets arranged at the rear end of the round-to-square cylinder and symmetrically distributed on the upper side and the lower side of the round-to-square cylinder, a throat adjusting mechanism used for driving the two convergence adjusting sheetsto rotate, a plurality of expansion adjusting pieces located between the two side walls and symmetrically distributed on the upper side and the lower side in the vertical direction, and an expansionsection adjusting mechanism used for driving the multiple expansion adjusting pieces on the upper side and the lower side to rotate around respective hinge points. According to the binary vectoring nozzle capable of achieving the rolling function, throat area adjustment and outlet area adjustment can be conducted, vectoring deflection within a large-angle range can be met, meanwhile, the defect that a conventional two-dimensional vectoring nozzle cannot generate rolling torque is overcome, the rolling function of the nozzle can be achieved, and meanwhile, the advantages of simple structure, high reliability and good invisibility are considered.

Description

technical field [0001] The application belongs to the technical field of aero-engine design, and in particular relates to a binary vector nozzle capable of realizing the rolling function. Background technique [0002] With the continuous improvement of aero-engine maneuverability and stealth requirements for new-generation aircraft, the vectoring nozzle, as a key component of the engine, faces the requirements of high stealth, high efficiency and light weight. The traditional aero-engine binary vector nozzle can adjust the throat area, generate pitch moment and yaw moment to realize the vector deflection function, but the motion mechanism is complex, heavy, unable to generate roll moment, does not have roll function, and has stealth performance Difference. Contents of the invention [0003] In order to solve at least one of the above technical problems, the present application provides a binary vector nozzle capable of rolling. [0004] This application discloses a binar...
