Description

Waveguide wire is inhaled in the guidance of underwater sailing body line traffic control

Technical field

The utility model relates to a kind of line traffic control guidance special wire of underwater sailing body.

Background technology

Underwater sailing body line traffic control guidance lead, take all factors into consideration various aspects: 1. intensity: underwater sailing body is from being transmitted into hit, the short then hundreds of rice of its conductor length, long then several kms, lead in the way of advancing, to bear with underwater sailing body and seawater between the effect of making a concerted effort of resistance, the creep power when the sail body direction changes and the acceleration of frictional force, the ocean current disturbance inertia force when changing or the like, requirement to the whole tensile strength of line traffic control lead is very high, so the selection of material must be considered strength problem by emphasis; 2. resistance to wear: lead produces friction with seawater in the way of advancing with underwater sailing body, because of friction makes the coarse and performance degradation of conductive line surfaces, therefore, require selected insulating material, its coefficient of friction is as much as possible little, resistance to wear is good as much as possible, drawing abillity will make any surface finish as much as possible, level and smooth, diameter no change, no concave-convex defective; 3. pliability: underwater sailing body will be followed target all the time and adjust direction and attitude in the way of operation, and therefore, lead is the variation of web response body Web fast, and not only tensile strength is wanted height, and very good pliability will be arranged; 4. fatigue resistance: change under water is because of being polynary, complicated, dynamic, and each becomes reliability and durability because of all testing lead, and owing to target range and matter of time, lead must be kept the stability of operating state all the time; 5. resislance to corrosion from sea water: seawater is a solution system, has wherein dissolved various mineral matter salts and organic substance on the earth, have many compositions be have corrosive; 6. conductivity: because underwater sailing body comes remote control by lead, so electrical insulating property and conductivity are very crucial characteristics; 7. continuous zero defect length: reaching in the length of several kms, as long as wherein there is a point that a defective or an inappreciable flaw are arranged, so, this sail body just will lose ability to act because of this defective and flaw.

Existing underwater sailing body line traffic control guidance lead, constitute by the conductor wire core at center and the insulating barrier of outsourcing, by selection to conductor wire core and insulating layer material, substantially can reach above-mentioned performance, but the guidance of such line traffic control does not still possess an important characteristic---radar wave camouflage power with lead, and radar wave camouflage power is vital afield, we can say, all can't survive afield without any the target of stealthy ability later, have only hidden oneself, could hit the enemy better.

Summary of the invention

The utility model provides a kind of underwater sailing body line traffic control guidance to inhale waveguide wire, its objective is the problem of the radar wave camouflage that solves prior art.

For achieving the above object, the technical solution adopted in the utility model is: waveguide wire is inhaled in a kind of underwater sailing body line traffic control guidance, comprises conductor wire core and external insulation layer, and ring is embedded with and inhales the ripple layer between described external insulation layer inwall and the conductor wire core periphery.

Related content in the technique scheme is explained as follows:

1, in the such scheme, described suction ripple layer is meant the stealth material layer of energy absorbing radar wave, but it can adopt the stealth material of existing various absorbing radar waves, but it is preferable under the prerequisite that guarantees stealthy function, select the material of thin light weight matter for use as far as possible, external diameter and weight with pilot, as: as described in suction ripple layer be composited by electrical impedance transform layer and Low ESR resonant layer, the electrical impedance transform layer is made up of ferrite micropowder and ethylene-tetrafluoroethylene copolymer, and the Low ESR resonant layer is made up of ferrite conducting staple fiber and ethylene-tetrafluoroethylene copolymer.

2, in the such scheme, the non magnetic silver-plated beallon line of the preferable employing high conductivity of described conductor wire core.

3, in the such scheme, the preferable employing cross-linking radiation of described external insulation layer ethylene-tetrafluoroethylene copolymer layer.This cross-linking radiation ethylene-tetrafluoroethylene copolymer layer is meant fluoroplastics (the English name abbreviation XLETFE) layer through cross-linking radiation.

The utility model design concept and principle are: be embedded the suction ripple layer that stealth material is made between the external insulation layer of lead and conductor wire core, guaranteeing that lead has under a series of original performances such as resistance to wear, intensity, pliability, fatigue resistance, making lead increase function again radar invisible.

3, because conductor wire core of the present utility model is the beallon line, external insulation layer is the fluoroplastics ETFE through cross-linking radiation, beallon is the alloy that performances such as machinery, physics, chemistry, mechanics are close to perfect adaptation, have strength degree, elastic limit, yield limit and the fatigue limit quite high with special steel, the beallon line is after the process Ageing Treatment, its tensile strength (1050～1585MPa), for oxygen-free copper (397～462MPa) 2.6～4 times, suitable with stainless steel wire! And the tensile strength of ETFE (60～70MPa), in the conventional thermoplastics that electric wire adopted is the highest, after handling through electron beam irradiation, its linearity molecular structure has become network structure, the tensile strength bigger lifting of having got back on the original basis! High-intensity conductor and high-intensity insulation, the lead of the two formation has underwater sailing body line traffic control lead now, more can adapt to the needs of modern national defense.

4, because the utility model outside is an external insulation layer, external insulation layer adopts XLETFE again, what directly contact with seawater in the use is the outer surface of external insulation layer, the XLETFE dynamic friction coefficient is (0.04～0.07), littler 5 times than the good nylon of lubrification in the common plastics (0.2～0.4), resistance to wear is super good.

5, because conductor wire core of the present utility model is the beallon line, the beallon line not only has more excellent elasticity and elastic limit than other any copper alloy wire, and elastic hysteresis is little, the elastic stability height, anti-fatigue performance is good, is well suited for the action feature of underwater sailing body.
