Background technique
FSS radome surface, which generally sprays defence, makes antistatic coating, has the function of anticorrosion and antistatic.And aircraft
Thunderstorm Weather can be in-flight encountered in the sky, and inevitably ash is struck by lightning, and for FSS radome, lightning leader is possible to
FSS radome surface is fallen in, is dodged by the way that the figure layer on FSS radome surface is sliding to lightning protection systems such as shunt bars, thus water conservancy diversion
To aircraft metal fuselage, finally release.
In the design process of FSS radome lightning protection system, the cunning lightning pressure of FSS radome surface covering is to thunder and lightning
The design of guard system has important influence, and traditional test method is tested using DC voltage or power-frequency voltage, then
It is realized in design by increasing biggish safe clearance, design result is more coarse.
Summary of the invention
The purpose of the present invention: the side of the sliding lightning pressure of FSS radar overcoat layer in the case of the accurate test lightning impulse of one kind is provided
Method.
Technical solution of the present invention: a kind of FSS radar overcoat layer thunder and lightning is sliding to dodge voltage test method, it is characterised in that described
Method are as follows: thunder and lightning generator exports lightning surge to radar overcoat layer by electrode according to thunder and lightning waveform, and records radar
The sliding sudden strain of a muscle voltage value of radar overcoat layer under two electrode difference spacing is covered, and fits the sliding sudden strain of a muscle voltage value of radar overcoat layer and electrode
The relation curve of spacing.
Preferably, the thunder and lightning waveform is GJB 3567-99 " military aircraft lightning protection qualification test method " regulation

Preferably, the equidistant increase of the spacing of two electrodes.
Beneficial effects of the present invention:
This method uses simulation thunder and lightning waveform as defined in GJB 3567-99 " military aircraft lightning protection qualification test method "
A wave and D wave measurement ensure that the data of test acquisition can be used in lightning protection and design and pass through radome identification examination
It tests, to keep the design of lightning protection more true and reliable.
Pellet electrode thickness is smaller can be guaranteed just to be attached to radome coating surface after electric arc occurs, and avoid the jump of electric arc
It jumps and punctures air, ensure that test result for sliding lightning pressure.
Electrode, which has the curved edge of smooth transition, and electrode is fitted in radome coating surface can be effectively reduced two
The sliding local voltage concentration phenomenon for dodging initial position being likely to occur between electrode, while electric current breakdown cover wall being avoided to enter in cover
The FSS screen in portion.
Semicircular electrode radius is more than or equal to 50mm, can effectively ensure that the sliding initial position that dodges between two electrodes in circle
Arc front end, to guarantee that the sliding spacing of dodging of electric arc is default space D.

Specific embodiment
Embodiment
When testing, electrode 1 and electrode 2 are bonded on radome surface, the symmetry axis of electrode 1 and electrode 2 is same
On straight line, the initial space D of electrode 1 and electrode 2 is 50mm.Testpieces 3 is placed on test fixture, electrode 1 and thunder and lightning
Generator connection, electrode 2 are grounded.
By adjusting thunder and lightning generator, thunder and lightning generator is enable to export GJB 3567-99 " military aircraft lightning protection mirror
Determine test method " as defined in simulation thunder and lightning waveform A wave and D wave.Then it is tested, records the collected mould of data acquisition equipment
The cunning lightning of coating surface presses U between quasi- lightning wave breakdown electrode 1 and electrode 2, uses the sliding arc dodged of digital camera record thunder and lightning
Road (is capable of deciding whether sliding dodge occur on radome surface by the arc road that digital camera is shot).It records to glide according to table 1 and dodge
Voltage U and electrode spacing D.
Table 1 is sliding to dodge graphic voltmeter
| Test waveform | Sliding lightning pressure (U) | Electrode spacing (D) |
Adjustment electrode D spacing is 100mm, records sliding lightning pressure, and so on, stop surveying when test to spacing is 400mm
Examination.The relation curve of sliding lightning pressure and electrode spacing is fitted according to the data recorded in table 1.
In case study on implementation, testing the thunder and lightning analog waveform used is GJB 3567-99 " military aircraft lightning protection identification
Test method " as defined in the waveform (as shown in Figure 3 and Figure 4) that uses of lightning protection qualification test, can authentic testing go out radar
Cunning lightning pressure of overcoat layer during qualification test provides truthful data for lightning protection design.
The click used in case study on implementation is semicircle pellet electrode, and electrode shape is as shown in Fig. 2, on radome surface
Bonding graph Fig. 5 shown in.For pellet electrode thickness in 0.1mm~0.15mm, electrode height can be guaranteed by being bonded in radome surface
The distance on radome surface is smaller out, after thunder and lightning is issued from 1 leading edge of electrode, before thunder and lightning can be along radome coating surface
Row, until reaching grounding electrode 2.
Electrode edge is that the arc with smooth transition can be avoided electrode leading edge and thunder and lightning centrostigma occurs, guarantee thunder and lightning from
The most leading edge of electrode 1 issues, and receives from the most leading edge of electrode 2, and the cunning lightning pressure tested out is the cunning lightning pressure of space D；It simultaneously can also
It enough avoids electrode from thunder and lightning concentration effect locally occur, generates coupling effect with the FSS screen inside radome and puncture radome cover
Wall reaches the FSS screen inside radome.
