Description
Technical field
The utility model relates to a kind of air breathing engine axisymmetric vectoring exhaust nozzle field, particularly relates to a kind of axisymmetric vectoring exhaust nozzle adjustment sheet sealing hold-down mechanism.
Background technique
At present, air breathing engine axisymmetric Thrust-vectoring Nozzle is in conceptual phase, because axisymmetric vectoring exhaust nozzle part-structure is spliced by convergence adjustment sheet and Divergent flap, when axisymmetric vectoring exhaust nozzle convergence, expansion, deflection vector, the sealing of convergence, Divergent flap is a very important problem, compressing to realize sealing, designing that a kind of structure is simple, the axisymmetric vectoring exhaust nozzle adjustment sheet of high financial profit, good sealing effect sealing hold-down mechanism is necessary.
Summary of the invention
The purpose of this utility model is to provide a kind of axisymmetric vectoring exhaust nozzle adjustment sheet to seal hold-down mechanism.
A kind of axisymmetric vectoring exhaust nozzle adjustment sheet sealing hold-down mechanism, mainly comprises interior clamping piece (2), external compression sheet (3), slide block (4), Compress Spring (5), bolt (1), nut (6).
External compression sheet (3) top symmetry has slide block movable guiding rail groove, slide block (4) bottom has tapped hole, interior clamping piece (2) is connected by middle bolt (1-2) with external compression sheet (3), Compress Spring (5) is installed between its nut (6) and external compression sheet (3), the adjustment sheet that axisymmetric vectoring exhaust nozzle is adjacent and diaphragm seal are bolted and are arranged between interior clamping piece (2) and external compression sheet (3), when adjustment sheet convergence expansion, 2 slide blocks (4) being arranged on external compression sheet (3) top are moved along with the convergence expansion of adjustment sheet in slide block movable guiding rail groove, realize sealing during axisymmetric vectoring exhaust nozzle adjustment sheet convergence expansion, Compress Spring (5) ensure that the compression of adjustment sheet and diaphragm seal.
2 bolts (1-1,1-3) that interior clamping piece (2) is held are threaded connection with slide block (4-1,4-2).
The face that interior clamping piece (2) and external compression sheet (3) and axisymmetric vectoring exhaust nozzle adjustment sheet, diaphragm seal are close to can according to the surface modeling of adjustment sheet with diaphragm seal, the sealability of guarantee jet pipe.
2 slide blocks (4) that flap sealing hold-down mechanism is arranged on external compression sheet (3) top are arranged symmetrically with, and structure is identical.
The utility model has the advantages that mechanical structure is simple, cost is low, the sealing that effectively can realize axisymmetric vectoring exhaust nozzle adjustment sheet compresses.
