Summary
editDescriptionSoufflerie de Tsiolkovsky.png |
Français : Soufflerie de Konstantin Tsiolkovsky. Le ventilateur centrifuge est mû par un poids. Le modèle à analyser est placé sur une sorte de bateau flottant dans un bac d'eau dont le recul entraîne une aiguille flexible, cette aiguille indiquant, en conséquence, la valeur de la traînée aérodynamique. English: Konstantin Tsiolkovsky blower. The centrifugal fan is driven by a weight. The model is placed on a sort of boat whose recoil in a water tank drive a flexible needle, the needle indicating therefore the value of the aerodynamic drag. |

Français : Cette aiguille est entraînée par le recul du modèle et de son "bateau". Comme elle est pesante (ou éventuellement flexible), un équilibre se produit entre son inclinaison et la force de Traînée : à chaque inclinaison de l'aiguille correspond donc une certaine force de Traînée.
