A laser-pushed lightsail is a thin reflective sail similar to a solar sail, in which the sail is being pushed by a laser, rather than the sun.The advantage of lightsail propulsion is that the vehicle does not carry either the energy source or the reaction mass for propulsion, and hence the limitations of the Tsiolkovsky rocket equation to achieving high velocities are avoided.
The Gen 3 laser has a number of upgrades that provide improved beam quality, increased electrical to optical efficiency, and reduced size and weight; the assembly is small at only 1.3 by 0.4 by 0.5 metres (4.3 ft × 1.3 ft × 1.6 ft), and is powered by a compact Lithium-ion battery to demonstrate deployability on tactical platforms. Beam ...
The Grumman F6F Hellcat is an American carrier-based fighter aircraft of World War II. Designed to replace the earlier F4F Wildcat and to counter the Japanese Mitsubishi A6M Zero , it was the United States Navy 's dominant fighter in the second half of the Pacific War .
HS Produkt d.o.o. is a Croatian firearms manufacturing company, best known for design and production of the HS2000 and XDM series of semi-automatic pistols, [4] [5] which are sold in the United States market by Springfield Armory, Inc., under their XD, XD-S, XD-M, Echelon and Hellcat brandings.
Lightcraft being propelled by laser. The Lightcraft is a space-or air-vehicle driven by beam-powered propulsion, the energy source powering the craft being external.It was conceptualized by aerospace engineering professor Leik Myrabo at Rensselaer Polytechnic Institute in 1976, [1] who developed the concept further with working prototypes, [2] funded in the 1980s by the Strategic Defense ...
The light section is a technology for optical 3-D measurement, which makes the measurement of a height profile along a projected line of light.
Ring Laser. Ring lasers are composed of two beams of light of the same polarization traveling in opposite directions ("counter-rotating") in a closed loop. Ring lasers are used most frequently as gyroscopes (ring laser gyroscope) in moving vessels like cars, ships, planes, and missiles. The world's largest ring lasers can detect details of the ...
An SLS machine being used at the Centro de Pesquisas Renato Archer in Brazil.. Selective laser sintering (SLS) is an additive manufacturing (AM) technique that uses a laser as the power and heat source to sinter powdered material (typically nylon or polyamide), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.
