Abstract
The utility model relates to a high-pressure air starting device of an aero-engine. The high-pressure air starting device comprises a main supporting frame, a feeding/returning mechanism and a locking/releasing mechanism of an air feeding gun head, wherein the main supporting frame is hinged on a test rack; a slide block of the feeding/returning mechanism is connected with a piston of a feeding air cylinder and capable of sliding on a guide rod; the two ends of a tension rod are respectively hinged with the main supporting frame and the slide block by hinge lugs; the shaft of the locking/releasing mechanism of the air feeding gun head can axially move in a shaft sleeve, and is capable of rotating with the shaft sleeve; and a locking clamp jaw which is fitted with a transitional part connected with the engine is further arranged on the air feeding gun head. The belt-drive starting of the engine can be carried out by the high-pressure air starting device disclosed by the utility model instead of a firework starter, so that the scientific research production cost is greatly saved. Moreover, the belt-drive time is short, the process is stable and the tightness is good.
Description
Technical field
The utility model relates to a kind of starting arrangement, especially a kind of aeroengine high-pressure air starting arrangement.
Background technique
Aeroengine, before being delivered for use, be carried out a series of ground experiment, to guarantee product, meets the flight requirement.In process of the test, need to be started motor, so that the parameter while gathering various work.The start mode of some aeroengine in real work is the pyrotechnics starting, belongs to disposable start mode.Although adopt the pyrotechnics start mode can carry out ground experiment, can greatly increase cost of production, also increased the Security of test run when wasting financial resources.At present, generally can adopt a kind of easy air rotary support starting, to the motor tail cone, circumferentially perpendicular to the position of playing moving vane, introduce high-pressure air, blow blade and then drive engine start.Although this structure is simple, can realize re-lighting, cost-saving, safe, but change the partial structurtes of motor tail cone and starting impeller, also there are a lot of deficiencies from starting arrangement reasonable structure, Security, sealing, therefore can't turn over journey by maximum likelihood simulation pyrotechnics starting band, affect the performance test of motor.
Summary of the invention
The purpose of this utility model is to provide a kind of air starting device that can substitute aeroengine pyrotechnics starter, overcome the deficiency of traditional air actuation mode, when guaranteeing that the high-pressure air band turns Security and sealing, better simulate pyrotechnics starter band and turn over journey.
Concrete scheme of the present utility model is: aeroengine high-pressure air starting arrangement comprises main bearing support, feeding/back body, send air gun head locking/trip gear, main bearing support is hinged on its Test Rig, feeding/back body comprises feeding cylinder, slide block, pull bar, guide rod, slide block is connected with the piston of feeding cylinder and can slides on guide rod, and the pull bar two ends are hinged with main bearing support and slide block respectively by the hinge ear; Send air gun head locking/trip gear to comprise axle, axle sleeve, spring, locking cylinder, axle sleeve is arranged on main bearing support, described axle can carry out axial motion in axle sleeve, simultaneously can be along with axle sleeve is rotated, one end of axle is provided with handle, the other end is provided with and send air gun head, spring is pressed between handle and axle sleeve, send on air gun head and also be provided with the locking claw that the transition member that is connected with motor matches, locking cylinder is hinged on main bearing support, and the support arm arranged on its piston and axle sleeve is hinged.
When the feeding steam-cylinder piston, in course of action, can be with movable slider to move along parallel guide rod, and then drive pull bar and pull main bearing support in falling down and erectility, the namely switching in off-position and working position for main bearing support.When promoting to send the handle on air gun head locking/trip gear, Compress Spring, axle will drive and send the air gun head straight line motion, until send the air gun head front end to enter the transition member be connected with motor, at this moment by the piston driving axle sleeve rotation of locking cylinder, and then drive and send the air gun head rotation by axle, block the locking claw of the transition member be connected with motor, realize to motor tail cone air feed.
The utlity model has significant effect at first, it can substitute the band that the pyrotechnics starter carries out motor fully and turn starting, has saved greatly the research and production cost.If calculate by the normal engine test program, need for every time band to turn number of times 8 times, cost-saved 120000 yuan.Secondly, this device can complete band and turn over journey under the prerequisite that does not change the motor self structure fully, and band turns that the time is short, process is steady, and sealing is good.Again, this device, after band turns end, can hightail motor, can not affect the test of engine performance.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The side view that Fig. 2 is Fig. 1.
Embodiment
As shown in the figure, aeroengine high-pressure air starting arrangement comprises main bearing support 7, feeding/back body, send air gun head locking/trip gear.Main bearing support 7 is hinged on its Test Rig, feeding/back body comprises feeding cylinder 3, slide block 2, pull bar 6, guide rod 1, slide block 2 is connected with the piston of feeding cylinder 3 and can slides on guide rod 1, and pull bar 6 two ends are hinged with main bearing support 7 and slide block 2 respectively by hinge ear 5; Send air gun head locking/trip gear to comprise axle 14, axle sleeve 13, spring 12, locking cylinder 8, axle sleeve 13 is arranged on main bearing support 7, described axle 14 can carry out axial motion in axle sleeve 13, simultaneously can be along with axle sleeve 13 is rotated, one end of axle 14 is provided with handle 11, the other end is provided with and send air gun head 15, spring 12 is pressed between handle 11 and axle sleeve 13, send on air gun head 15 and also be provided with the locking claw 16 that the transition member that is connected with motor matches, locking cylinder 8 is hinged on main bearing support 7, and the support arm 10 arranged on its piston and axle sleeve 13 is hinged.
At work,
At work, feeding cylinder 3 piston action, can along parallel guide rod 1, move by band movable slider 2, and then drive pull bar 6 pulls main bearing support 7 in erectility, make to aim at for air gun head 15 transition member be connected with motor, then promote to send the handle on air gun head locking/trip gear 11 Compress Springs 12, axle 14 will drive and send air gun head 15 motions, until send air gun head 15 front ends to enter in the transition member be connected with motor, now by piston driving axle sleeve 13 rotations of locking cylinder 8, and then drive and send air gun head 15 rotations by axle 14, block the locking claw of the transition member be connected with motor, realization is supplied gas to be with to motor and is turned.After motor completes and specifies the band of supplying gas to change a job to do the time, locking cylinder 8 reversing motions, make to send air gun head 15 rotations to break away from the transition member be connected with motor, and under the spring force effect, make the rifle head return to initial position, then start 3 reversing motions of feeding cylinder, drive bearing support 7 rotations and fall down.
