Lesson Two: in terms of fundamental historical
Venturitubes 1937.pdf
On the pictures below you can see how small the venturi nozzle is to drive the gyroscopes in the strands. My finger and applied on the next hand, illustrate the size of the venturi tube. It is almost equal to the diameter of my finger. Now, please imagine how much energy to give the fan with the same diameter of my finger...
Since the narrowest point of the venturi tube, we can easily get up to 10 times higher air velocity, we can mount the engine behind the jet frame, which at high speeds the inlet has a good performance.
For example, you can mount an engine on an Tourist Plane, which reaches 200 km / h at the entrance to the RAM JET would be about 2000 km / h....
This will generate additional good sequence, using a very simple engine ( or two )
