No thank you, finally, for a very specific question. Because of this specific not yet had my manual is not yet complete. But a few important tips I can already provide, for a good while I’m thinking about it already… [http://www.new4stroke.com/vent5.jpg](http://www.new4stroke.com/vent5.jpg) First units 10 and 15 miles is 16 km / h - 24 km / h or 4.5 m / s to 6.75 m / s Now I think that should do the nozzle of the same size and calculations as in my post # 434. Now this: the witrze 15 miles in the throat nozzle of dimensions we will have theoretical speed 167 miles (270 km / h) … the valve on the power of the fan is due at the speed we can get even theoretically about 20 Hp to get the power from the electric generator, you must already quite large in size,. I could barely fit for him to die in his throat. and it completely obscured. It must therefore be outside the nozzle and be driven by a toothed belt from the propeller., and this is the biggest problem. Same cones and these dimensions can all be done the hard styrofoam by cutting the thermal cutting CNC polystyrene. Most important thing is that the external surface of the cone must be round, full, of the 1000 mm dimension. Theses external surface of the throat must have the dimension. So that the air nozzle was skipping necessarily the way to the straight line, otherwise may not have a good performance at all. All these figures are just patterns of cones. The figure pointed to the red line is the nozzle look like on the outside. [http://www.new4stroke.com/Venturi1000a.jpg](http://www.new4stroke.com/Venturi1000a.jpg) Why is it important to air bypassing the nozzle on the outside was the shortest path in a straight line? not because I’m imagining that the venturi nozzle is so very close to collapse like a normal airplane wing over and over. its aerodynamics will surely like this over and over again folded wings. wing and best for low speed is the lower edge of a straight line. here shown theoretically how to wrap the wing sites. Now Lifting force of this wing will also “wrapped” inside, creating a negative pressure in the whole nozzle … [http://www.new4stroke.com/fold.jpg](http://www.new4stroke.com/fold.jpg) It’s a rough … Andrew:D --- _[View the full topic](https://boards.straightdope.com/t/iris-engine-hype-or-the-real-deal/546505)._
