  • No, i just used my own airfoil...

    i just tried to make a nice thin airfoil...

  • Ne schöne Steigerung zum ersten Bau. Läufts auch so gut, wenn der Rotor etwas weiter vom Ventilator entfernt steht, so das alle Rotoren gleich stark umströmt werden?

    Und welches Profil hast du verwendet?

  • hab ein symetrisches profil verwendet.versuche mit einem asymetrischen profil fuehrten zu geringeren drehzahlen.

    wenn ich den rotor weiter weg vom verntilator stelle dreht er sich nicht annaehrnd so schnell.weil eifnach viel "weniger" wind auf die fleugel trift.die fluegel werrden aber in dieser position beinahe gleich stark um stroemt...

  • fantastic little presentation. what plans did you follow? i am intersted of builing one .

    thanks

    great work

  • thank you....i actually havent followed any plans.i had to do a school project and just found some information on the internet.after building a prototyp i built this one.

  • Did you use a standard airfoil, like the NACA0018?

  • At first I didn't think it was working because it wasn't moving fast enough, but by the end it was really moving! Do you have any idea what the TSR was? What shape wings did you use?
