Description
Technical field
It the utility model is related to technical field of cable, and in particular to a kind of broadband absorbing shielding aviation single electricity
Cable.
Background technology
Traditional aviation single-core cable, formed by center conductor and around the insulating barrier of center conductor, the unshielded knot in periphery
Structure, to connect aviation electronics electrical equipment, transmit direct current or low-frequency alternating signal.
In airborne wiring, the identical or different cable composition of some specification frameworks is a branch of, navigates within cable trough, will
Input connects with output electronic apparatus part with system, coordinates aircraft to complete aerial mission.
When aircraft is static not actuated, cable such as neutral net is covered with aircraft whole body, by driving cabin, cabin, wing, empennage,
Undercarriage and all airborne electrical equipment are connected as an organic whole, though Aircraft Cables do not transmit operating current and signal, its
Function is consistent with when working, and receives and comes from free space electromagnetic wave, now, cable is antenna, the electromagnetism received
Ripple is converted to electromagnetic pulse immediately including microwave, is arbitrarily propagated along cable system.
When taking off work, if cable transmission Constant Direct Current electric current, cable surrounding space will be filled with electrostatic field and quiet
Magnetic field, sensing and the other cables in coupling near field and electrical equipment, produce sensing electrostatic and magnetostatic；If cable transmission alternating current and low frequency
Signal, then cable surrounding space will be filled with alternating electric field and alternating magnetic field, sensing and coupling near field and the other cables in far field and electricity
Device, generation alternating electric field and alternating magnetic field, cable now, such as interference source, interference of electromagnetic field aircraft system caused by coupling
Work.
Generally, such as fine, Weather-stable, no thunder and lightning and hurricane, no menace of wars, also pantaphobia force do
Disturb and steal flight information, then traditional single core unscreened cable or can meet to substandard aircraft security operation needs.
If aircraft is opportunity of combat, or is war service, or by terrorist forces it is of interest and threaten, then, the unshielded electricity of single
Cable, it is impossible to ensure that aircraft safety is run, situation is as follows：
First, this single-core cable will be used as signal receive and transmitting antenna, utilized by hostile force, several meters,
In hundreds of meters of even farther distances, flight secret can be stolen easily, or Remote causes me with striking target
Side is without predictable loss.
2nd, this single-core cable will into machine space radiation electromagnetic wave, turn into interference source, disturb other cables and
Airborne equipment works；For exclusive PCR, machine inner part, component and system need to additionally install wave filter, increase and fly
Machine load, workload and complexity.

The electromagnetic wave penetrated, the alterating and direct current, radio wave frequency ranges from low frequency are to microwave frequency band, all possible as dry
Means are disturbed, wherein, low-frequency disturbance（50~5kHz）, based on magnetic-field component, High-frequency Interference（5M~50GHz）Using electric field component as
Main, intermediate frequency interference, electric field component has concurrently with magnetic-field component；Disturbed device and system, generate induction field and magnetic field respectively, with
Induced-current and induced signal conduct along cable, spread to connected airborne equipment and to whole frame aircraft, occur erroneous judgement,
Malfunction, delay machine and failure, make the reduction of aircraft normal function.
4th, more severe patient, if aircraft irradiates by enemy's HIGH-POWERED MICROWAVES, this microwave penetration fuselage, radiation
To internal body space, then, the cable receives the antenna of microwave by turning into immediately, and cable is immediately changed into self
Weapons of destruction, aircraft will face the paralysis and extinction of chain landslide formula.
Although the 5, current stage, microwave weapon is not yet comprehensive and large scale investment battlefield, various countries' armament are competing
In match and military force deterrence action continuing fermentation, defend the motherland peace, protection our people's safety of life and property are intended to,
We must provide for a rainy day, and carry out war defence in advance and prepare.
Based on this, it is believed that, in aircraft industry, particularly with development military secret new varieties, existing military secret attack is improved with preventing
Imperial ability and civil aircraft requisition is used for opportunity of combat at any time in wartime, the unshielded Aviation cable of traditional single core, with new technology
Demand, a pair of technical contradictions are constituted therebetween, how to solve this contradiction, be that Aviation cable industry is pursued technological progress, carried
Rise product function and strengthen the important topic of national defence fighting capacity.
