Français : Expérience de Konstantin Tsiolkovsky démontrant le principe de la propulsion par réaction.
Afin de faire comprendre le principe de la propulsion à réaction, Constantin Tsiolkovski a proposé sa fameuse expérience "de la barque". Une personne se trouve démunie d'avirons dans une barque à l'écart de la rive. Il veut rejoindre cette rive. Il remarque que la barque est chargée d'une certaine quantité de pierres et a l'idée de lancer, une à une et le plus vivement possible, ces pierres dans la direction opposée à la rive. Effectivement, à la quantité de mouvement des pierres jetées dans un sens correspond une quantité de mouvement égale pour la barque dans l'autre sens. English: Konstantin Tsiolkovsky's thought experiment demonstrating the principle of jet propulsion.
In order to understand the principle of jet propulsion, Constantin Tsiolkovski offered his famous experience "of the boat". A person finds himself without oars in a boat away from the shore. He wants to reach this shore. He notices that the boat is loaded with a certain quantity of stones and has the idea of throwing, one by one and as sharply as possible, these stones in the direction opposite to the shore. Effectively, to the momentum of the stones thrown in one direction corresponds an equal momentum for the boat in the other direction. |
