- Ahem. Actually, it was the Nazis of WW11. Follows
- stuff from authoritative sources(tm) :
-
- .......
- Luftkanone. Developed at Talstation Lofer, Germany, during WWII.
- Developer: Dr. Richard Wallauscheck.
-
- Best quote here:
-
- "...design consisted of a parabolic reflector, 3.2 meters in diameter,
- having a short tube which was the combustion chamber or sound
- generator, extending to the rear from the vertex of the parabola.
- The chamber was fed at the rear by two coaxial nozzles, the outer
- nozzle emitting methane, and the central nozzle oxygen. The length
- of the chamber was one-quarter the wavelength of the sound in air.
- Upon initiation, the first shock wave was reflected back from the
- openend of the chamber and initiated the second explosion. The
- frequency was from 800 to 1500 impulses per second.
- The main lobe of the sound intensity pattern had a 65 degree
- angle of opening, and at 60 meters' distance on the axis a pressure
- of 1000 microbars had been measured. No physiological experiments
- were conducted, but it was estimated that at such a pressure it
- would take from 30 to 40 seconds to kill a man. At greater ranges,
- perhaps up to 300 meters, the effect, although not lethal, would be
- very painful and would probably disable a man for an appreciable
- length of time. Vision would be affected, and low-level exposures
- would cause point sources of light to appear as lines." [1]
-
- The device was not deployed, due to complexity and lack of range.
-
- Also, a device that created vortices in the air, and a device that
- shot 'plugs' of air were developed at the same facility, primarily
- for low-level anti-aircraft defence.
