A directed-energy weapon (DEW) is a ranged weapon that damages its target with highly focused energy without a solid projectile, including lasers, microwaves, particle beams, and sound beams. Potential applications of this technology include weapons that target personnel , missiles , vehicles, and optical devices.
Testing was planned to cover a range of sonic boom overpressures on the ground similar to but higher than those anticipated from the proposed American SST. [94] In 1966, AV-2 was selected for the program and was outfitted with test sensors. It flew the first sonic boom test on 6 June 1966, attaining a speed of Mach 3.05 at 72,000 ft (22,000 m ...
"In developing a military weapon, scientists intend to revert to a policeman's whistle form, perhaps as big as eighteen feet across, mount it on a truck and blow it with a fan turned by a small airplane engine. This weapon, they say, will give forth an all-destroying 10,000 acoustic watts. It could kill a man five miles away.
Modern sonic weapons such the Long Range Acoustic Device (LRAD) rely on multiple loudspeaker drivers for increased sound power, and may array them in a flat plane rather than on a parabolic surface. Such weapons do not use parabolic reflectors which necessarily limit the number of drivers—a large area of drivers aimed at the reflector would ...
The death ray or death beam was a theoretical particle beam or electromagnetic weapon first theorized around the 1920s and 1930s. Around that time, notable inventors such as Guglielmo Marconi , [ 1 ] Nikola Tesla , Harry Grindell Matthews , Edwin R. Scott , Erich Graichen [ 2 ] and others claimed to have invented it independently. [ 3 ]
