@extricate:
if you prepare exam, flight licences, Atpl instructor qualification, etc. or if you want a well paid carrier in aerospace, stay on 1.
If you want to understand how birds fly, how unloading the wing works, how spacecrafts come back on earth, how butterfly flies, ...how nature allows lift goto 2!
1. If you want to get your exams, please, just write as it is written in YOUR books. Your teachers teach the lift as these crazy theories give them their salaries, to get famous, for some of them to get Nobel prices. And forget... (maybe you will finish like AF447 in the ocean, take a good insurance to help your family : all that is only statistics! "So many millions NM anf flights have not accident..." STOP.
GOTO END
2. You want really fly like birds! Just look seriously the sky : can you really imagine the air is continuous, homogen, isotrope? NO NO NO. So forget ALL the continuous equations: Bernouilli, speed model, pressures equations like navier-stokes or Kutta,Lanchester :First learn Fractals,(it is difficult),dynamic systems (sampled fractals...), and plastic rupture! It is a nice story. Good kuck. And never forget. STOP.
GOTOEND.
END.
