Summary[edit]
| Description |
Français : Animation du vol du 24 septembre 1852 du dirigeable à vapeur d'Henri Giffard, d'après la gravure de L. Guiguet tirée de : LES BALLONS DIRIGEABLES, Expériences de M. Henri Giffard en 1852 et en 1855 et de M. Dupuy de Lôme en 1872, par Gaston Tissandier, 1872
[1]. Le dirigeable mesurant 44 m, on peut calculer que sa vitesse dans cette animation est de 6,3 m/s (22 km/h), ce qui est le double ou le triple de la vitesse annoncée par Giffard (2 à 3 m/s). Cette animation existe aussi en vidéo WebM : . |
