The invention discloses a two-dimensional plug type vectoring thrust nozzle with an adjustable throat area and an aircraft. The two-dimensional plug type vectoring thrust nozzle with the adjustable throat area comprises a round-rotating square cylinder body, a first static arc wall, a second static arc wall, a first dynamic arc wall, a second dynamic arc wall, a first adjusting plate, a second adjusting plate, a cone, a first actuating cylinder, a third actuating cylinder, a second actuating cylinder, a fourth actuating cylinder and a side wall plate; and the first actuating cylinder, the second actuating cylinder, the third actuating cylinder and the fourth actuating cylinder move cooperatively, so that a synchronous motion state and an asynchronous motion state are provided. According tothe two-dimensional plug type vectoring thrust nozzle with the adjustable throat area, throat adjustment and overall deflection of a rear section of the nozzle are realized by utilizing one set of actuating system, the capacity of large-range adjustment of the throat area and the capacity of the overall deflection of the rear section of the nozzle are achieved, and the airflow loss can be reducedthrough the overall deflection of the rear section.
Description
technical field [0001] The invention relates to the technical field of nozzles, in particular to a binary plug-type vector nozzle with adjustable throat area and an aircraft. Background technique [0002] The range of the working envelope of the aero-engine is getting wider and wider, and the range of the drop pressure ratio reaches tens, so a nozzle with stronger expansion capacity is needed; [0003] The existing pre-researched binary plug vector nozzle with adjustable throat area has a small adjustment range of throat area, and the vector adjustment can only be adjusted to a single component to achieve vector deflection, resulting in a large airflow loss. [0004] Therefore, it is desirable to have a technical solution to overcome or at least alleviate at least one of the above-mentioned drawbacks of the prior art. Contents of the invention [0005] The object of the present invention is to provide a dual plug-type vector nozzle with adjustable throat area to overcome ...
