Description
Technical field
The invention belongs to aero-engine two-dimensional nozzle design field, particularly to two-dimensional nozzle control
Mechanism processed design field.
Background technology
Throat area controlling organization can realize the regulation of nozzle throat area, is the important of jet pipe
Building block.The controlling organization of existing two-dimensional nozzle throat area mostly is rocking arm and adds support mode
Or regulation ring adds support mode, and pressurized strut is arranged along nozzle axis direction, above-mentioned controlling organization
Structure is complex, and spare part number is more, and needs to occupy bigger space.
Summary of the invention
It is an object of the invention to: propose a kind of simple in construction, two-dimensional nozzle larynx that reliability is high
The controlling organization of road area.
The technical scheme is that the controlling organization of a kind of two-dimensional nozzle throat area, including
1,2 slide track seats 2 of 2 pressurized struts, support 3 and 2 pull bars 4, this controlling organization is 2
Set, arranges in the upper and lower lateral symmetry of two-dimensional nozzle.Particularly as follows: pressurized strut 1 one end is hinged on side
On wall C, the other end and support 3 are hinged；Slide track seat 2 is fastenedly connected on load wall B,
Sliding-rail groove E is had on it；There is bulge-structure support 3 one end, embeds the sliding-rail groove on slide track seat 2
In E, constituting sliding pair, opposite side is hinged with pressurized strut 1, pull bar 4 respectively；Pull bar 4 is another
One end and converging portion D are hinged.When the piston rod of pressurized strut 1 is retracted or stretches out, drive support 3
Slide downward or upward along slide track seat 2, and then drive pull bar 4, it is achieved to converging portion D's
Control.When the controlling organization of the upper and lower both sides of jet pipe is synchronized with the movement, can be realized by control convergence section
The regulation of nozzle throat area, the vector that can also realize binary contracting nozzle during asynchronous movement pushes away
Enter.
1) support 3 is Integral rigid reinforcement structure, often overlaps the number of controlling organization medium-height trestle 3
Amount is 1, on it pin joint for connecting pressurized strut be at 2, at 4, at 6 or at 8,
Etc. about quantity arrange, uniform along nozzle axis direction, pressurized strut 1 number should be mutually 2,
4,6 or 8, be also etc. to arrange about quantity, uniform along nozzle axis direction；
2) the sliding-rail groove E on slide track seat 2 can be vee gutter, rectangular channel, circular trough,
Swallow tail shaped slot.
The invention have the advantage that throat area controlling organization simple in construction proposed by the invention,
Compact, motion couplings is few, and reliability is high, and synchronicity is good, it is possible to effectively realize two-dimensional nozzle
The control of throat area and the vector Solid rocket engine of binary contracting nozzle.

Detailed description of the invention
Embodiment 1
Below the present invention is described in further details.See Fig. 1～Fig. 7, a kind of binary spray
The controlling organization of pipe throat area, including pressurized strut 1, slide track seat 2, support 3 and pull bar 4,
This controlling organization is 2 sets, arranges in the upper and lower lateral symmetry of two-dimensional nozzle.Particularly as follows: pressurized strut
1 one end is hinged on sidewall C, and the other end and support 3 are hinged；Slide track seat 2 is fastenedly connected
On load wall B, it has sliding-rail groove E；There is bulge-structure support 3 one end, embeds slide track seat
In sliding-rail groove E on 2, constituting sliding pair, opposite side cuts with scissors with pressurized strut 1, pull bar 4 respectively
Connect；Pull bar 4 other end and converging portion D are hinged.The piston rod of pressurized strut 1 is retracted or stretches out
Time, drive support 3 to slide downward or upward along slide track seat 2, and then drive pull bar 4, real
The now control to converging portion D.When the controlling organization of the upper and lower both sides of jet pipe is synchronized with the movement, can lead to
Cross control convergence section and realize the regulation of nozzle throat area, binary during asynchronous movement, can also be realized
The vector of contracting nozzle advances.Often in set controlling organization:
1) pressurized strut 1 quantity is 2, arranges in the jet pipe left and right sides, and cylinder end cuts with scissors respectively
Being connected on the sidewall C of the jet pipe left and right sides, tailpiece of the piston rod and support 3 are hinged；
2) slide track seat 2 quantity is 2, with bolts is fastened on load wall B, its
On to have sliding-rail groove E, sliding-rail groove E be triangle；
3) support 3 quantity is 1, and there is bulge-structure one end, embeds the cunning on slide track seat 2
In rail groove E, constituting sliding pair, the other end is hinged with pressurized strut 1, pull bar 4 respectively, support
It is used on 3 and the pin joint number of pressurized strut 1 connection is at 2, be used for and pull bar 4 connection
Pin joint is also at 2；
4) pull bar 4 quantity is 2, and for triangular draw bar, a pin joint and support 3 are hinged,
Two other pin joint and converging portion D are hinged.
