Description
Technical field
This utility model relates to a kind of jet engine axisymmetric vectoring exhaust nozzle field, particularly relates to a kind of expansion formula dual vector jet pipe of receiving from the mechanism connected.
Background technology
At present, jet engine axial symmetry Thrust-vectoring Nozzle is in tentative conceptual phase, owing to axisymmetric vectoring exhaust nozzle part-structure is to be spliced by convergence adjustment sheet and Divergent flap, when axisymmetric vectoring exhaust nozzle convergence, expansion, deflection vector, convergence, Divergent flap sealing be a critically important problem, and the adjustment sheet of a lot of vector spray and diaphragm seal are more difficult work and installation, and also want hold-down mechanism so that it is sealing property is not high.
Utility model content
For solving above technical problem, this utility model provides following technical scheme: a kind of expansion formula dual vector jet pipe of receiving is from the mechanism connected, including adjustment sheet, diaphragm seal, rotating shaft, bolt, hole cylinder roller and adjustment sheet side cover.
Adjustment sheet arranged outside has adjustment hole, adjustment sheet lower end is provided with installing hole, adjustment sheet is provided with two closed chambers in left and right, adjustment sheet side is provided with guide-track groove simultaneously, the position that adjustment sheet is corresponding with adjustment sheet side cover is provided with screwed hole, diaphragm seal is divided into diaphragm seal 1 and diaphragm seal 2, the position of diaphragm seal 1 and diaphragm seal 2 corresponding matching is set to circular arc, diaphragm seal and hole cylinder roller are connected by revolute, when adjustment sheet convergence expansion, hole cylinder roller is in sealed interior rolling, drive diaphragm seal 1 and diaphragm seal 2 to pass in and out closed chamber simultaneously, realize the sealing during convergence expansion of axisymmetric vectoring exhaust nozzle Divergent flap.
Further, described diaphragm seal is divided into diaphragm seal 1 and diaphragm seal 2, is set to circular arc on the position of diaphragm seal 1 and diaphragm seal 2 corresponding matching, and diaphragm seal 1 and diaphragm seal 2 are connected by rotating shaft, forms revolute.
Further, two closed chambers of described adjustment sheet are provided with block.
Further, described adjustment sheet side cover is attached by the guide-track groove being arranged on adjustment sheet, is fixed with bolt.
The utility model has the advantages that frame for movement is simple, cost is low, it is possible to the sealing effectively realizing axisymmetric vectoring exhaust nozzle Divergent flap compresses.

Detailed description of the invention
As shown in Fig. 1 and Fig. 2, Fig. 3 and Fig. 4, a kind of expansion formula dual vector jet pipe of receiving is from the mechanism connected, including adjustment sheet 1, diaphragm seal 2, rotating shaft 3, bolt 4, hole cylinder roller 5 and adjustment sheet side cover 6, adjustment sheet 1 arranged outside has adjustment hole 1-3, adjustment hole 1-3 is used for the control of the convergence to adjustment sheet 1 and expansion, adjustment sheet 1 lower end is provided with installing hole 1-2, by revolute, the casing of installing hole 1-2 and jet pipe is connected, adjustment sheet side cover 6 is attached by the guide-track groove 1-4 being arranged on adjustment sheet, is fixed with bolt 4.
At jet pipe when divergentnozzle, it is pulled outwardly adjustment sheet 1 by adjustment hole 1-3, the hole cylinder roller 5 in closed chamber 1-5 is now driven to roll, diaphragm seal 1 and diaphragm seal 2 is promoted to move outside closed chamber 1-5, now diaphragm seal 1 and diaphragm seal 2 can be expanded outwardly by rotating shaft 3, and due to the cooperation of diaphragm seal 1 and the circular arc 2-3 of diaphragm seal 2 cooperation position, complete the expansion task of jet pipe spout, there is good sealing effectiveness.
At jet pipe when restraining spout, adjustment sheet 1 is inwardly pushed away by adjustment hole 1-3, the hole cylinder roller 5 in closed chamber 1-5 is now driven to roll, diaphragm seal 1 and diaphragm seal 2 is pulled to move in closed chamber 1-5, now diaphragm seal 1 and diaphragm seal 2 can toe-ins by rotating shaft 3, and due to the cooperation of diaphragm seal 1 and the circular arc 2-3 of diaphragm seal 2 cooperation position, complete the convergence task of jet pipe spout, there is good sealing effectiveness.
Detailed description of the invention described in the utility model is not intended that the restriction to the application scope; within every spirit in this utility model design and principle, any amendment that one of skill in the art can make, equivalent replacement and improvement etc. should be included within protection domain of the present utility model.
