The laser and the sky
The main researcher of the laser-driven technology of the Green laser pointer spacecraft engine is Raike Mirabe, a professor of aerospace engineering at Rensselaer Polytechnic Institute in Troy, New York. Mirabe is an expert in directed energy, space motive force, aerospace systems, and advanced propulsion. From 1996 to 1999, he used a high-energy external laser with a power of up to 10kW at the Baisha missile launch site in New Mexico to launch a prototype laser-powered aircraft. In 2000, he made a laser-propelled aircraft fly to 71m. It is reported that this experiment using high-energy lasers to research aircraft is currently being carried out in Brazil. In a laboratory in Brazil, a hypersonic seismic wind tunnel is connected to two pulsed infrared lasers, with a maximum power of 1 billion W. It is reported that this is the laser propulsion experiment with the highest power in the world so far.

Compared with traditional cutting methods, laser technology has many advantages, such as small laser spot, high energy density, fast cutting speed, low thermal deformation, high precision, strong flexibility, low noise, good cutting quality, high production efficiency and energy saving. To the application of large abrasive tools, etc., in recent years, this "fastest knife" has been widely used in the field of aviation manufacturing. For example, the laser can cut a series of high hardness, high melting point metal and non-metal special aviation materials, including titanium alloys, aluminum alloys, nickel alloys, chromium alloys, stainless steel, beryllium oxide, composite materials, plastics, ceramics and quartz, etc. . In the manufacturing process of aviation equipment, laser cutting is suitable for processing countless parts: engine flame tube, engine casing, aircraft frame, aircraft skin, wing stringer, tail wall panel, honeycomb structure, helicopter The main rotor...
