i have this info to share the pulse engine used in the socalled arora . it works on the principal that after reaching a speed ??? the maximum of a conventional engine a new system kicks in it is a venturi affect engine whitch draws atmosphere in thru a venturi compressing it and when it reaches a certain pressure it creates a pressure diffference so great that it creates a pulse with such force it produces thrust , once the aircraft is at the optimum speed the engine becomes reliant on only its own speed to produce its thrust and no longer uses fuel ,this is why it is able to travel such great distances , the vapour trail it produces with the doughnut rings are caused by the compression of moisture emitted from the pulse it does therefore have a maximum ceiling for flight , for there must be atmosphere for it to work , to high and the oxygen gets to thin to create thrust ,

Quote: The venturi effect happens because fluid pressure drops as the fluid speed increases. If you force a fluid (for example: air or water) down a tube with a narrowing in it, the fluid will move faster through the narrow part. When it starts to move faster the pressure drops. In in internal combustion engine this is commonly used in carburetors to mix fuel with air. Air is sucked in the mouth of the carburetor and flow through the "throat" or narrow part of the carburetor. When it does this the pressure drops below the pressure of the air outside and sucks fuel from a small hole in the throat (the fuel "jet") with the fuel sprayed into the air, the mixture travels through the intake manifold into the cylinders where it is burnt for energy. A vortex is very easy to see. When you drain water from a sink there is a depression that forms over the drain. The water swirls around this depression as it travels to the drain. This swirling is caused by the Coriolis force from the rotation of the Earth. The vortex effect and the venturi effect are used together in Internal combustion engine to improve efficiency by making the fuel and air mix better in the throat of the carburetor, and as the fuel-air mixture moves down the intake manifold to the cylinder. "Swirl" a form of vortex, is used inside the cylinder to make the combustion of the fuel-air mixture occur smoothly and predictably. This increases efficiency and make the engine run smoothly. So, the vortex and venturi effects don't really help the gas move faster, but they encourage fuel and air to mix better giving a more even and efficient fuel burn. End Quote

I didn't understand this at first, so I did a bit of looking around. This explanation helped me a bit. So I post it for those that are venturi effect challenged.

Interesting, but I believe that it doen't use 0 fuel but a much less more explosive ratio of fuel. The high altitudes, but large amount of o2 "air" being (ram Aired) into the engine by the fuction of speed alowes less fuel to be consumed for a equal amount of thrust. In conjuction with pulse thrust technology. This Aroura craft should be able to fly many times faster then the speed of sound.

Somewhat like the J-58 engine used on the SR-71A at or above Mach 2.5.

You're better off just reading the Wikipedia article than the OP.

PDEs don't rely on the Venturi effect, and they do use fuel. They also are useful even at low speeds, so there's no need to have a conventional turbofan engine to supplement them.




it is a venturi affect engine whitch draws atmosphere in thru a venturi compressing it and when it reaches a certain pressure it creates a pressure diffference so great that it creates a pulse with such force it produces thrust


If you just compressed the incoming air and then expanded it again, you wouldn't gain anything and in fact would only lose energy to friction. A PDE creates a large pressure difference by mixing the air with fuel and detonating it. This doesn't have anything to do with the Venturi effect.

Questio. If the new engine does not burn fuel when operating at ??? speed.
Why does the amount of oxygen have any meaning?
