Missile design criteria is to minimize the weight of the structure in order to guarantee the necessary payload during the structural design can not leave a large margin, so the missile shell material to produce a softening effect when, in their flight the role of aerodynamic stress easily deformed or even disintegration. This target shell deformation or disintegration of the scene of the damage the target known as structural mechanics destruction. When the laser is in optoelectronic devices so that the temperature rise will seriously affect the technical performance of optoelectronic devices and render ineffective. For example, a photoelectric detector, the temperature is too high, the light is too strong it will greatly affect image quality, and even does not work. This case is the destruction of optoelectronic devices. china laser pointer can improve the users’ modern information tools use level.
Thermal ablation destruction of aircraft defense pathway. Laser weapons developed by the United States are mainly rely on the power density threshold damage target launch a short-pulse high-energy laser, such as the Airborne Laser, the transmit power for space-based laser weapon 2 ~ 3MW ship transmit power for the Airborne Laser and ground-based lasers will eventually reach MW-board laser weapons "Nautilus" has a transmit power of 500kW, both nanosecond pulse width and micron wavelength, each fired a duration of 3 ~ 6s. Laser radiation to targets in the air after some time need to be stable in a fixed position to accumulate enough energy to the target burned. The factory adopts the advanced laser technology ofchina laser pointer.
The foregoing analysis, we know that, in such a powerful high-power pulsed laser irradiation does not make sense to increase the thermal conductivity of the target material for the defense laser thermal ablation damage, the defender should focus on the following aspects: The aircraft should be rolling flight. Rotating flight of the missile body, scroll flying satellites in orbit irregular tumbling flight, the aircraft immediately in the event of laser irradiation, the laser can not be pegged to a fixed part of the aerial targets accumulation of energy, extend the time by the laser burned, effective defense of the thermal ablation destruction. Aircraft shell can be anti-laser structure design. American Studies for satellites, aircraft, missiles, aircraft anti-laser ablation destruction of the protective shell structure. How to choose suitable china laser pointer?
Missile, for example, the anti-laser protective structure will not increase too much the total cost and total weight of the missile. This anti-laser ablation structure has two heat-resistant layer, sandwiching a layer of anti-laser ablation of the barrier layer, three layers bonded together, solid joint to the outer surface of the missile shell. An early missile shell structure (called a structure), Figure 2 shows the shell structure of the modern missile (called the 2 structure), Figure 3 for the anti-laser missile shell design structure (called structures). A structure includes a metal shell (11), the fuel seal bushing (12). 2 structure, 23 outsourcing layer 21 of the missile shell structure of the glass fiber composite materials, sealing bushing 22 as fuel. 3 structure is the structure of anti-laser ablation. The customer should select the suitable china laser pointer as per the cost.
Missile shell contains a layer of glass fiber component 31, the fuel seal bushing 32, 33, 34, 35 The role of anti-laser ablation, 33, 35 of which is heat-resistant layer can be cork composite materials (cork, phenolic, cork epoxy resin, cork nitrile rubber), the thickness can be at 0? a choice between 1 ~ 1cm; 34 ablation barrier, generally of carbon fiber fabric impregnated with heavy metals, resin. Experiments show that this structure has a strong anti-laser ablation performance. The application of laser resistance material and coating technology increases the reflection coefficient of the vehicle shell laser. Experiments show that the laser wavelength between 1 ~ 10μm, all kinds of pure metals have more than 90% of the reflection coefficient. The security of green laser pointer is of importance.
