Description
Technical field
The invention belongs to aeroengine two-dimensional nozzle design field, particularly the improvement of two-dimensional nozzle control mechanism.
Background technique
Throat area control mechanism can realize the adjustment of nozzle throat area, is the important composition parts of jet pipe.Existing two-dimensional nozzle throat area control mechanism is many arranges pressurized strut outside adjustment sheet, pressurized strut operating ambient temperature is higher, easily there is hydraulic oil leakage problem, simultaneously distant between the pressurized strut of both sides up and down, lazy-tongs design difficulty is larger, in addition, due to pressurized strut present position, when safeguarding, the accessibility of staff is poor.
Summary of the invention
The object of the invention is: propose a kind of pressurized strut good work environment, structure simple, be easy to the two-dimensional nozzle throat area control mechanism safeguarded.
Technological scheme of the present invention is: a kind of two-dimensional nozzle throat area control mechanism, is characterized in that: comprise fitting seat 1, pressurized strut 2, rocking arm 3, pull bar 4, wherein rocking arm 3 has idle rod 3-1 and driving arm 3-2.This control mechanism is 2 covers, with jet pipe horizontal central plane for reference level is symmetrical arranged up and down.
Be specially: fitting seat 1 is fastenedly connected on sidewall B; Pressurized strut 2 one end and fitting seat 1 hinged, the driving arm 3-2 of the other end and rocking arm 3 is hinged; Rocking arm 3 through sidewall B and and sidewall B hinged, while and driving arm 3-2 be fastenedly connected, idle rod 3-1 and pull bar 4 one end hinged; Pull bar 4 the other end and converging portion C hinged.When 2 cover control mechanisms are synchronized with the movement, can realize the adjustment of nozzle throat area, the vector that can also realize binary contracting nozzle during asynchronous movement advances.
1) often overlap in control mechanism, fitting seat 1, pressurized strut 2 are identical with the quantity of the driving arm 3-2 on rocking arm 3, are 2, are symmetrical arranged in the jet pipe left and right sides, can be arranged on outside sidewall B, also can be arranged on sidewall B inner;
2) often overlap in control mechanism, rocking arm 3 quantity is 1, is rigidity reinforced structure, and the quantity of the idle rod 3-1 on it is identical with the quantity of pull bar 4, is 2 ~ 8;
3) the driving arm 3-2 on rocking arm 3 is demountable structure, is fastenedly connected with rocking arm (3).
Advantage of the present invention is: pressurized strut operating ambient temperature is low, upside or downside pressurized strut synchronous can be realized by rigid swing arm, lazy-tongs are between the two easy to design, whole control mechanism is simple, compact, reliability is high, be convenient to safeguard, effectively can realize the control of two-dimensional nozzle throat area and the vector Solid rocket engine of binary contracting nozzle.
