Abstract
The invention relates to a high pressure air starting device for an aero-engine, which comprises a main bearing frame, a feeding/returning mechanism, and an air feeding spearhead locking/releasing mechanism, wherein the main bearing frame is hinged on a test run rack, the sliding block of the feeding/returning mechanism is connected with the piston of a feeding cylinder and can slide on a guiding rod, two ends of a pull rod are respectively hinged with the main bearing frame and the sliding block by hinge lugs; the shaft of the air feeding spearhead locking/releasing mechanism can perform axial movement in a shaft sleeve, and meanwhile can rotate along with the shaft sleeve; and a locking jaw which is matched with a transitional component connected with an engine is also arranged on the air feeding spearhead. The high pressure air starting device can completely replace a fireworks starter to perform the rotation starting of the engine, thereby greatly saving scientific research production cost; in addition, the air starting device is short in rotation time, stable in process and excellent in sealing property.
Description
Technical field
The present invention relates to a kind of starting arrangement, especially a kind of aeroengine high-pressure air starting arrangement.
Background technique
Aeroengine will be carried out a series of ground experiment before being delivered for use, meet the flight requirement to guarantee product.In process of the test, need to start motor, so that the parameter when 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, when wasting financial resources, also increased the Security of test run.At present, can adopt generally speaking a kind of easy air rotary support starting, namely circumferentially introduce high-pressure air perpendicular to the position of playing moving vane to the motor tail cone, blow blade and then drive engine start.Although this structure is simple, can realize re-lighting, save cost, safe, but change the partial structurtes of motor tail cone and starting impeller, on starting arrangement reasonable structure, Security, sealing, also there are a lot of deficiencies, 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 invention 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 invention 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 at 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 installed on the 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 the axle sleeve, send and also be provided with the locking claw that the transition member that is connected with motor matches on the air gun head, locking cylinder is hinged on the main bearing support, and the support arm that arranges on its piston and the 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 spur main bearing support and be in and erectility, namely be used for main bearing support in the switching of off-position and working position.When the handle that promotes to send on the 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 that is connected with motor, at this moment the piston driving axle sleeve by locking cylinder rotates, and then drive by axle and to send the air gun head rotation, block the locking claw of the transition member that is connected with motor, realize to motor tail cone air feed.
The present invention has significant effect at first, and 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, every inferior band that needs turn number of times 8 times, cost-saved 120000 yuan.Secondly, this device can be finished band and turn over journey under the prerequisite that does not change the motor self structure fully, and band turn the time short, process is steady, sealing is good.Again, this device can hightail motor after band turns end, can not affect the test of engine performance.

Fig. 2 is the side view of 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 at 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 installed on the 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 the axle sleeve 13, send and also be provided with the locking claw 16 that the transition member that is connected with motor matches on the air gun head 15, locking cylinder 8 is hinged on the main bearing support 7, and the support arm 10 that arranges on its piston and the axle sleeve 13 is hinged.
At work,
At work, 3 actions of feeding steam-cylinder piston, can move along parallel guide rod 1 by band movable slider 2, and then the main bearing support 7 of drive pull bar 6 pullings is in erectility, make for air gun head 15 and aim at the transition member that is connected with motor, then promote to send the handle on the air gun head locking/trip gear 11 Compress Springs 12, axle 14 will drive and send air gun head 15 motions, until send in the transition member that air gun head 15 front ends enter with motor is connected, this moment is by piston driving axle sleeve 13 rotations of locking cylinder 8, and then drive by axle 14 and to give air gun head 15 rotations, block the locking claw of the transition member that is connected with motor, realizing supplies gas to be with to motor turns.After motor is finished and is specified the band of supplying gas to change a job to do the time, locking cylinder 8 reversing motions, make and send air gun head 15 rotations to break away from the transition member that is 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.
