Is this Theory
of Flight ?

MIT on
Theory of Lift in a wind Tunnel
On a little reflection (which took me 50 years!), Bernouilli should
only
be called “Theory of Lift in a Wind Tunnel”, not “Theory of Flight”.
In flight, the air has no momentum. The model does
not model reality.
The Emperor got it wrong. However, the Newton
approach survives.
Garrick Mound, 68, is a volunteer guide for the
Science Museum. He travels up from Somerset to do this. He is Geology (oil) and
(I think) Biology.
Professor Jack Dinsdale, 78, was with me doing
Engineering in Cambridge, and in my college Trinity.
I lost contact with all other fellow scholars, and more or less lost
contact with Jack.
Garrick was the guide for me around the science museum, and I lectured
him as much as he lectured me, for 90 minutes! It was as if a tsunami hit him.
Because of the RAF connection, Garrick showed me lots of planes. This
got me back to thinking of
Theory of Flight. I felt
such an idiot when 20 years ago I realised I had been sold a pup, Bernouilli, when I stumbled on the Newton theory. Although
the Science Museum is History of Science, not "Science", Garrick
agreed that history of theory of flight could play its part. The Smithsonian
has History of theory of Flight, and Garrick said he would suggest adding it in
the Science Museum.
I called Jack, and he confirmed my memory of what we were taught in
Cambridge - Bernouilli. He said years later he asked
students how planes could fly upside down. He also confirmed in 1957 we were
shown the pitot tube with
lower pressure when the liquid travelled faster.
I find that today MIT still teach Bernouilli,
no Newton.
10 or 15 years ago I found the new theory, Newton's Second Law, on the
www. It is now removed. 20 years ago the Smithsonian gave both theories, Bernouilli and Newton, hedging their bets.
The next stage is to realise that Bernouilli
and Newton are theory of lift in a wind tunnel, not theory of flight. In the
case of flight, the air is stationary. I thought I had just thought of it, but
then I found it on my website 10 years or so ago. http://www.ivorcatt.com/2606b.htm
. The Newton Americans still have the air flowing from left to right.
It is extraordinary that all "experts" have confused the wind
tunnel case with theory of flight for so long. No wonder the electromagnetic
theory of such people is such a silly mess.
