Add airplane design to the growing list of things that you know nothing about. Complex mechanisms today begin life as 3D CAD models with finite element analysis.
I suppose you could be more wrong, but I am not quite sure how. If I am patient, however, I am sure you will show how it might be done. Do you honestly think that an aircraft manufacturer actually spends the money on a model of a potential project right off the bat? Well, apparently you do given your stupid comment.
Contrary to what you may have seen on the comercials, staying at a Holiday Inn Express does not make you an expert at anything.
If you would stop and use your brain for just a second, you wouldn't look half as stupid. Just think for a second about the requisite steps that must be considered before a model could even be seriously consided.
a) before even the most basic shape of an aircraft can be considered, one must first consider what one wants the aircraft for. Fighter? Cargo? Passenger? Private? Performance? Aerobatic? You really think an aircraft goes right into the modelling process before even considering what sort of aircraft it will be?
b) Once you have determined what the aircraft will be used for, then you must consider the actual job it will be expected to perform. For that, one must consider the various wing configurations and lifting surfaces available
c) Next you begin the process of selecting and or designing airfoils. Fixed or perhaps variable wing geometry? You think it is time for a model yet? I don't think so.
d) At this point, you will probably do a 3 view drawing of the aircraft either on paper or in a cad program...but you still aren't to the modelling phase.
At this point, months and hundreds of thousands of dollars have been spent and you still aren't ready for modelling yet.
e) Now you are ready to start making an inborard profile of the aircraft...roughing out where the major components will be...engine position, hydraulics, cables, resivors, fuel etc., etc., etc.
f) Once you have decided where the components will be, long before you ever put a skin on the drawings, you perform a weight and balance analysis....and perhaps a rudimentary stability analysis to determine if some rearrangement is necessary.
g) make an isometric drawing.
h) And now, at long last, you have enough data on the aircraft in question to begin to model it...
But even now, you are a long way from having a completed model
And you can bet your ass that if the computer model fails at any point or doesn't jibe with wind tunnel observations, the design is scrapped and they go back to the drawing board before any more money is thrown down the toilet after a flawed project.
Climate science has failed at the modelling process. The models don't work and rather than go back and reexamine the hypothesis...they insist that their heat is just hiding...
