Boeing is working on a new flat plane that would be able to take off and land vertically using dozens of new pulse jets they call Pulse-Ejector-Thrust-Augmentors. Of course, these things were originally created by Nazis

of the TR-3B?

The design seems so solid that the Pentagon is actually contemplating the possibility of using them to build a large flat VTOL aircraft capable of transporting tanks and troops with ease. newtstuff.blogspot.com...
This was a basic pulse jet research project to find the effects of varying physical tube length and diameter had on the cycle pulse frequency , stability and thrust produced.
The jet tube was straight and of constant daimeter.
In 1906 The Russian engineer V.V.Karavodin obtained a patent for an airbreathing pulse-jet engine . In 1907 he built a working engine based on his invention. Basically the system produced a high velocity pulsed gas jet generated by a cyclic combustion of a liquid hydrocarbon fuel /air mixture.
His tests and development work where based on a fixed pulse jet tube.
Today in aeronautics the pulse jet is more commonly known as an air breathing RAM jet.
Once airborne the forward velocity of the engine compresses or 'rams' the air at the in take and improves the cycle efficiency.
The SCRAM jet technology currently being proposed for reducing first stage launcher costs is a direct descendent of these humble beginings.

PETA technology..."new" pulsejet ejector thrust augmentor, Ummmm...does this aircraft look familiar?
