laser for China's largest air show opened today in China's space industry into wings
Review: 2014 Airshow in Zhuhai today kicked off today coincides with the 65 anniversary of the Chinese air force, the air force will for the first time into a presentation system equipment. among them, domestic shipping-20 and f-31 public entity for the first time to participate in exhibitions aroused much public concern, while Russia Su-35 fighter and United States air show in C-17 military transport aircraft were also the first appearance, becoming much-anticipated star. at this air show, three of the world's big industrial powers, America and Russia gathered for the first time military aircraft to Zhuhai. laser technology as the one of the world's most advanced manufacturing and processing technology, high efficiency, low energy consumption, short process, performance, digital and intelligent features. it applications within the aerospace sector, for the rapid development of China's aerospace industry plays an important role in promoting.
1, laser cutting
in space aviation equipment of manufacturing in the, shell used special metal made, strength high, and hardness high, and resistance high temperature, General of cutting means hard completed material of processing, laser cutting is a efficient of processing means, available laser cutting processing aircraft cast skin, and cellular structure, framework, and wing bin, tail avoidance Board, and helicopter main spin wing, and engine machine magazine and flame tube,. the continuous output of the laser for laser cutting, also useful for high repetition rate pulsed carbon dioxide lasers. laser cutting depth to width ratio, for non-metallic, aspect ratio is above 100, metal up to 20 per cent. high speed laser cutting, cut Chin alloy sheet 30 times for the mechanical method, is a mechanical method of cutting steel plate 20 times. the laser cutting quality. compared with plasma and oxyacetylene cutting, cutting carbon steel the best quality.
laser cutting technology in the aerospace sector is mainly used in Aero-Engine, turbine blades, laser drilling, laser cutting of aviation engines and so on.
