Count the laser technology applications in aerospace area
China has already been a superpower in space, for Shenzhou manned spacecrafts, Chang’e series’ moon exploration, Tiangong series’ spacelabs and BeiDou Navigation Satellite System, which shows the great accomplishments to the world. The advanced modern aerospace needs advanced manufacturing craft and technology. Laser technology is indispensable for high-precision welding, cutting and assembling procedure. So, how laser technology is used in aerospace?
Laser ranging technology
Laser ranging technology is the first laser technology applied in military. In late 1960s, the army equipped laser range finder because it is able to measure the target distance quickly and accurately, which are widely used for reconnaissance surveys and weapon fire control systems.
Laser guided weapons have high precision, simple structure, and are not susceptible to electromagnetic interference, so they play an important role in precise guided weapons.
laser communication technology
Laser communication has large capacity, good confidentiality and strong anti-electromagnetic interference capability. Fiber communication has become the focus in the development of communication systems. Airborne, spaceborne laser communication system and that for submarines are also under development.
Strong laser technology
A tactical laser weapon made of a high-power laser can blind human eyes and disable the photodetector. At present, anti-satellite and anti-continental ballistics using high-energy laser beams may destroy military targets such as aircraft, missiles, and satellites. The application of strategic laser weapons that are close to practical missiles is still in the exploratory stage.
Laser cutting technology
Due to the small light spots, high energy density and high cutting speed, laser cutting gets nice quality and extremely high cutting speed &efficiency, while reducing tool wear.
Laser welding technology
The use of laser welding materials can avoid deformation, increase the type of welding materials, eliminate environmental factors which is high-quality and efficient.
laser additive manufacturing
Aerospace vehicles are becoming more and more advanced, lighter, and more maneuverable. Additive manufacturing technology is a "magic bullet" to meet these requirements.
