Description
Technical field
The present invention relates to the synchronous drive-type rear culvert channel injector in a kind of variable cycle engine adjusting mechanism, for changing engine behavior to adapt to different flying conditions, belonging to the high-performance gas turbogenerator technical field in aerospace engineering.
Background technique
The design of external variable cycle engine is started in 20 century 70s, and domestic variable cycle engine designs and just starts to carry out this century.The adjusting mechanism of variable cycle engine mainly comprises three parts: mode switching valve, front duct ejector, rear culvert channel injector, after wherein rear culvert channel injector is positioned at low-pressure turbine, before tail pipe burner, coordinating with mode switching valve, front duct ejector and regulate, is the requisite part of adjusting mechanism.
The rear culvert channel injector that US Patent No. Patent4069661 proposed in 1978, in duct, directly arrange pressurized strut, the driving mode of this Earlier designs, shortcoming is a lot of, as blocked air-flow, hydraulic system difficult arrangement etc., be substantially eliminated in design afterwards.
The rear culvert channel injector that US Patent No. Patent4409788 proposed in nineteen eighty-three, adopt external pressurized strut, an active rotating shaft drives bar to drive two rotating shafts by orthodrome, pressurized strut is positioned over casing outside by it, significantly reduce the adverse effect of actuation mechanism for runner air-flow, but the orthodrome that its shortcoming is to connect each rotating shaft drives bar not to be domain design, and rigidity is not enough, does not possess synchronism; Structure does not possess cyclic symmetry, causes motion inharmonious, likely in adjustment process, occurs stuck phenomenon.
The rear culvert channel injector that US Patent No. Patent5307624 proposed in 1994, adopt Rotary actuator, a rotary actuator Direct driver valve body, pressurized strut is positioned over casing outside (being embedded on outer casing), its shortcoming be circumference only place's active force in valve body, peripheral force skewness, causes motion inharmonious, likely in adjustment process, occurs stuck phenomenon; Rely on rotating shaft Direct driver valve body to move, comprise translation and rotation, wherein only have axial translation to affect the switching effect of valve body, drive efficiency is low.
The rear culvert channel injector that US Patent No. Patent5343697 proposed in 1994, adopts external pressurized strut, and the rotating shaft of an active drives three driven rotating shafts, introduces ball pivot and bearing, adds the flexibility of mechanism.Its shortcoming is valve body at a place by driving force, and its excess-three place is subject to resistance, the serious skewness of peripheral force, is easy to cause motion inharmonious, in adjustment process, occur stuck phenomenon; Rely on rotating shaft Direct driver valve body to move, comprise translation and rotation, wherein only have axial translation to affect the switching effect of valve body, drive efficiency is low.
The rear culvert channel injector that Chinese patent 200920277531.X proposed in 2009, adopts external pressurized strut, and circumferentially a circle pressurized strut, drives one piece of valve sheet respectively.Its shortcoming is casing shape need too high, and casing needs need there be a step arranging pressurized strut at correct position; Pressurized strut number is too many; Connecting rod is too many, and integrating error are large.
To sum up, asymmetric easily stuck, the shortage synchronism that causes of above-mentioned prior art ubiquity structure causes inharmonic deficiency and shortcoming, the present invention propose device adopt synchronizing ring with ensure actuator everywhere synchronism, taken into account the symmetry properties of mechanism simultaneously, effectively overcome the shortcoming of this respect.
