Good Afternoon Rotorheads,
This is a question that is aimed at you chaps who are able to undo the technical jargon and reply to us mere mortals in earth type language,
I have read recently that a Professor in America has stated that the (forgive my spellings) Bernoulli effect and theory is wrong, and that if you replaced this with a wing or blade section that was of parallel or straight sided section (without all the convex and concave surface that we have now) it would work just as well, for the action of flight and or lift occurs because of the angle of attack of a blade or wing incidence allied to the speed/power applied to the A/C when pushed through the air.
Now this guy could be right , if he is would that mean that wings and blade profiles would change and be cheaper and stronger, or is the current metheod of design and way of manufacture correct, therefor making Mr Bernoulli spot on after all.
This story was in the Sunday Times about 2/3 weeks ago, and begs quite a few extra questions about "Old theories" mainly connected with the physics of engineering and transmission of bodies either solids or fluids.
Whilst obviously all current designs embody the tear drop type sections in wings and blades, what do you people out in Pprune land think about this will things alter or stay the same?
