| | Tak tu mame novu betu pre x-plane, kde zasa o kus pokrocili v letovom modele.
Zaujalo ma toto:
Further flight-dynamics refinements... I think we can actually, consistently, pull off a pretty decent approximation of a SPIN now!
The secret: No longer does the airplane really have any idea of a flight path!
Instead, each PART of the airplane has it's OWN flight path.
So now, an airplane is NOT really a single entity: It is a whole bunch of parts all moving in formation!
As odd as this seems, THIS is the way to understand how EACH bit of the airplane has it's OWN flight path (different for each bit of the airplane if the plane is pitching, yawing, or rolling), and THIS is the secret that really allows us to get a good SPIN: Each bit of the wing, stabilizer, etc all have their own flight path angle and speed... this builds up the forces in the dynamic cases of hi spin-rates: Most noticeable, not surprisingly, in a spin. We have had an approximation of this since version 1.00, but only now, for 9.30 Beta-8, have we really completely overhauled the physics to really have no concept at all of the flight path of the 'airplane', and instead handled it totally independently for each ELEMENT of each surface of the plane. This, combined with the new wind model that has no concept of the wind on the 'airplane', but instead knows the wind on each BIT of the airplane. THIS is really where we start to get into serious computations to learn new things about how the plane will fly.
