Thank you NC Cams for your statement.

In case of the second Prototype I want to calculate the centrifugal force pushing the rotary vanes. The vanes measure 60 x 40 x 6mm an they weight about 30 grammes. The possible continuous turning speed should be 2500 rpm. At this rpm the vanes will be pushed with 16 kg or 35 lbs against the housing. How much load do you think to need for tightening up?
In beginning I thought I need to pressurize the vanes from outside. With the first Prototype I tried it with different air pressure, but it was not necessary. The engine turned even slower because of the rising friction.

I know there will come problems to be solved. No one can aspect to develop a perfect new engine in such short time with only one person.

In 1876 as Nicolaus August Otto invented his Otto-engine he surly did not think about the complicated engines we have in our car today.
Any common rail diesel pump is more complicated than the RotaTorque-engine. The question is, if it is the right way to make the Otto-engine more and more costly by mechanic, just to save a tiny little bit fuel, or to think about another kind of combustion engine.
It is a difficult way because leading engineers will newer admit, 130 years of work may have gone into the wrong direction.

We all have seen what human intelligence is able to build. If I can get the manpower and the money to develop the RotaTorque for series, I am sure everyone wants to get this smooth enormous power the RotaTorque produces without any vibrations or oil change.
