4. What's more important - how you go into the air or how you go out.
A "sharp" looking front end means not that this vehicle got a good
aerodynamic.
More important is a correct rear end - the car has to go properly out of the
air, means, the airflow has to go off the rear end without producing
turbulences - if the air collapse hard behind the rear end, the car will be
slowed down due to a vaccum which the airflow than creates - faster you go,
more vaccum and turbulence you produce, and your accelaration "slows" down.
And therefore you need the 6 degrees rule - if the body shape is clean with a
so angle designed you get a smooth rip off of the air from the rear end.
A belly tank is designed to the aeroplane 7 degrees rule - it looks not so,
but here is a mathematical 7 degrees form designed - the shape is out of
radius, one radius goes in other different radius, but at last the tangential
between is based on the 7 degrees - sorry this very complex to
understand....but it works....see a water drop.
This for today
See ya
Pork Pie
I add this.
5. Coke bottle - this design was developed for high speed, means close or over
the transonic, sound barrier speed - but it didn't work well on Craig
Breedlove's Sonic 1 in 1965.
6. Profile - with the diamond ord wedge design they mean the cross section of
main body on an aeroplane - means the center part where the pilot is sitting
in and th emost of the aggregate and very often the engine is in.
