Description
Technical field
It the utility model is related to carbon fibre material unmanned plane field, more particularly to a kind of electromagnetic shielding applied to unmanned plane
Structure.
Background technology
Unmanned plane will carry out accurate, stable flight, mainly detect aircraft state in real time by airborne sensor, then instead
Flight control system is fed to, after flying control processing, then exports corresponding control.Because the airborne end of unmanned plane needs to carry out in fact with ground surface end
When data, image, the signal such as control transmission, and the operating current of unmanned plane is larger, and curent change is fast, causes aircraft machine
Complex electromagnetic interference is produced between load equipment；In addition, unmanned plane is at work, it is also possible to runs into complex electromagnetism
Interference environment；These electromagnetic interferences can have an impact to the sensor of aircraft or airborne equipment etc., cause the aircraft state of feedback
Deviation or mistake are produced, it is more serious, directly result in sensor or equipment malfunction.Therefore, it is necessary to carry out electromagnetic screen to unmanned plane
Design is covered, improves the electromagnet shield effect of aircraft, reduces influence of the electromagnetic environment to sensor or airborne equipment as far as possible.
For industrial unmanned plane field instantly, because it is to the rigidity of structure, intensity, weight, environmental suitability, fatigue etc.

The processing such as warm carbonization, graphitization form carbon fiber wire, and for phosphorus content more than 95%, electric conductivity is good, but not magnetic conduction；By carbon fiber
Silk is infiltrated with epoxy resin, and after being fabricated to carbon fibre prepreg, its electric conductivity is poor, but possesses certain electric conductivity.
When carrying out design of Electromagnetic Shielding, main way has current carbon fibre material unmanned plane：
It is electromagnetically shielded by carbon fibre material itself；Because of the carbon fiber wire good conductivity of carbon fibre material, but epoxy
Resin matrix is non-conductive, and after being stacked into structural member by carbon fiber laying, the electric conductivity of integral material is deteriorated.In weaker electric field
Under disturbed condition, carbon fiber possesses certain electrical shielding efficiency；But in the case of stronger electric jamming, the electric screen of carbon fibre material
It is very poor to cover efficiency.
It is electromagnetically shielded by copper foil；It is electromagnetically shielded with copper foil, although copper product has good electric conductivity, because
Copper foil is harder, poor ductility, weight weight, can not be integrally formed with carbon fiber structural (greater curvature type face can not paving, during shaping
Cause carbon fiber component moderate finite deformation), and the later stage also can not complete machine structure paving copper foil, therefore can only make in the regional area of body
With.It is generally used for around the more sensitive sensor of electromagnetic wave, mainly GPS module, the geomagnetic sensor of this inside modules
It is more sensitive to electromagnetic wave, it is easy to be disturbed.But this shielding mode, electromagnetism that can only be by internal body equipment to GPS module
Certain shield effectiveness is played in interference, if copper foil is unable to good earth, or copper foil region is smaller, and diffraction occurs for electromagnetic wave, then to GPS
Or there can be certain interference.
