  • In this video you can see a Grasshopper definition for propeller design.

    Amazing! One option for improving the design flow is to select attack angles not via user input but by evaluating lift and drag force curves. If Grasshopper supports Python you can pull those curves from SplineCloud

    Theory from Betz? Goldstein? Glauert? Theodoresen? Larrabee? …???

      The theory of the finite element of the blade, that of Xrotor. The code is limited to drawing and switching between: Xrotor < --- > Aircode/Design

      Something is not correct. The chord at the blade root is too large. The circulation goes to zero at the root - the finite chord need only meet structural size requirements while alpha attenuates toward cl=0 at the root. You’re chopping off too much trailing edge which should not be there in the first place.

      Ci tengo sottolineare che il video vuole mostrare come io sia riuscito, con Rhino7, a disegnare eliche in pochi minuti e con un controllo totale dei principali parametri. Se tu mi dessi questi parametri, ottenuti in qualche modo, potrei disegnarti l'elica in pochi minuti, oppure, potrei giungere alla convergenza tra requisiti e analisi reiterando modifiche e analisi. I applicazione disegna in pochi secondi, mentre Xrotor calcola in pochi secondi, (configurarlo è più lungo), e così la valutazione è rapida. Non volevo dire che l'elica è perfetta.

      So sorry. I do not read Italian.
