A fictional modernized version of the P24, perhaps the one that would fly to the Reno Air Racing Championship. The colors came from the original 1935 Paris exhibition, and as a revised model has a streamline cockpit and new 5 blade propeller.
Except the purely aesthetic changes I made few aerodynamical additions. The new version is made as an experiment for flow separation (stall). You can see a functional leading edge slat with a moving smaller wing set to pitch, and 12 smaller vortex generators. The vortex-Gen is also controllable and set as pairs. If you ascent they divert from each other, and in dive they converse. I was hoping to create lower speeds at the top of the main wind in descent. Our good friend Bernulli in his principle, pointed that pressure in fluids is inversely proportional to speed, so controllable pressure difference is beneficial in both actions (ascent and descend). In real life Vortex-generators also help to make more linear the flow on top of the wing, reducing the separation bubble in stall. I am not sure if the V-G helped at all in reducing stall, but I have better control in pitch. With this version if you slow reduce power to 53%, keep pulling up and lower Flaps and Slats, you could make controllable speeds almost until 55mph and fly strait with almost 30 degrees attack angle.
You are welcome to make comments and express opinions about the functionality of movable vortex generators in this build, and of course add ways to improve them.
