Description
Technical field
The present invention relates to a kind of debris colleting device, for collecting fragment when carrying out the experiment of lightning direct effect.
Background technology
Civil aircraft largely communicates, navigation antenna is installed on outside airframe, will according to civil aircraft seaworthiness environment
Ask, need to carry out lightning direct effect experiment installed in the antenna equipment of aircraft exterior.
The experiment of lightning direct effect is simulation lightning when being attached to equipment under test, it is possible to create destruction.Whole experiment bag
Include high voltage adhiesion test and the experiment of high current physical damage.Since the antenna installed in aircraft exterior carries nonmetallic materials
Antenna house.Antenna house is fixed to antenna metal by modes such as fastener, bondings and installs on pallet.Broken carrying out high current physics
During bad experiment, antenna house is under the action of lightning power, it is possible that situations such as burning, tear, smashing, so that in high current
Fragment is produced during failure test., it is necessary to be collected to issuable fragment during experiment, it is analyzed to the secondary of aircraft generation
Influence.
In early period existing testing program, experiment process is generally observed and recorded using photographic means, while to the broken of generation
Piece is observed.But since the lightning discharge process of high current physical damage experiment gives birth to strong light, even if being exposed during photograph using delay
The mode of light, its photographic quality can not also ensure clearly to record issuable all fine debris during experiment,
And the important informations such as size, the weight of fragment can not be understood by way of photo.
Also there is the earth mat by being laid with large area in experiment tread in traditional scheme, by earth mat to being produced in experiment
Fragment be collected.But since the energy that high current physical damage experiment process produces is very big, often occur that fragment splashes
Situations such as distant and fine debris can not collect.Therefore there are easily produce what is omitted during garbage collection for this method
Defect, while also limited be subject to test site size.
Since high current failure test is the process of lightning power abrupt release.During big energy moment, surrounding air is caused
Drastically expand, if using completely enclosed collection device, be easy to produce air burst.Therefore in design debris colleting device
When, it is necessary to consider air pressure release aperture.While design pressure release aperture, while need to avoid the presence due to release aperture
Fragment is caused to fly out collection device by release aperture.
The content of the invention
Therefore, it is an object of the present invention to provide a kind of debris colleting device, it is to overcome lightning direct effect to overcome
During experiment, the defects of garbage collection is not complete.
The purpose is realized by a kind of debris colleting device tested for lightning direct effect.The debris colleting device

Glass is insulating materials, result of the test can be impacted to avoid it.Organic glass has certain intensity at the same time, is carrying out
In the state of the design of air pressure release aperture, requirement of strength design disclosure satisfy that.Organic glass has good translucency at the same time,
Experiment process is recorded and analyzed with reference to photographic means during easy to test
In addition, the hole at top plate center is round hole, has a diameter larger than equal to 58mm and be less than or equal to 62mm.
Preferably, top slot extends up to the sidewall paneling of Circular Cylindrical Thin Shells from hole.Thus electric discharge can be adjusted in the horizontal direction
The position of electrode.In addition, sidewall channels connected with napex groove, vertical are additionally provided with sidewall paneling.Thus can be along vertical side
To the position for adjusting sparking electrode.The width of top slot and sidewall channels is more than or equal to 19mm and is less than or equal to 21mm.
As the improvement of the present invention, 1 to 3 row is vertically equipped with sidewall paneling, circumferentially direction is evenly arranged
Air discharge holes, often row 10 to 50 air discharge holes are set, for while being discharged without prejudice to pressure, preventing fragment from releasing
Fly out in discharge hole.Preferably, air discharge holes are circle, have a diameter larger than equal to 5mm and are less than or equal to 50mm.
Preferably, fine and closely woven gauze is made of glass fibre.
Preferably, watch window is connected with watch window cover board by nonmetallic screw.It is nonmetallic it is meant that screw
It can be made of materials such as composite material, carbon fibre materials.
