Français : Appareil de Gustav Magnus pour ses expériences de 1852. L'Académie de Berlin ayant offert un prix pour qui trouverait la cause de la dispersion aléatoire des projectiles d’artillerie, le physicien Gustav Magnus découvrit cette cause et publia en 1853 un exposé intitulé "Sur la déflexion des projectiles et un phénomène particulier observé sur les corps tournant". |

Ces flèches bleues symbolisent l'écoulement d'air qui frappe le cylindre tournant perpendiculairement à sa direction.
Ces flèches bleues symbolisent l'écoulement d'air qui frappe le cylindre tournant perpendiculairement à sa direction.
Cette flèche colorée pour Wikipédia symbolise la portance qui naît de l'Effet Magnus. Il faut remarquer que Gustav Magnus n'a pas publié de mesures d'efforts...
Ce signe "moins" symbolise la zone dépressionnaire qui crée l'Effet Magnus (en association avec la zone de surpression opposée).
Ce signe "plus" symbolise la zone de surpression qui crée l'Effet Magnus (en association avec la zone de dépressionnaire opposée).
Dans ce cadre est le cylindre rotatif étudié par Gustav Magnus.
On peut remarquer que ce cylindre ne dispose pas de disques d'extrémités, ce qui doit, par ventilation de son aval limiter la valeur de la Portance due à l'effet Magnus.
