Ce livre pr�sente, en d�tail et avec planches, deux grandes parties du syst�me Gabriel Yon: le ballon captif transportable reli� par c�ble et le dirigeable � vapeur destin� � la haute vitesse. Il expose l’ensemble, de la production de gaz hydrog�ne pur � la propulsion par une machine � vapeur, en passant par le treuil et le syst�me de t�l�phonie de bord.

Le texte d�crit le mat�riel et son fonctionnement, les composants m�caniques et les choix de conception, ainsi que les performances et les mesures g�n�rales. On y d�couvre comment le ballon captif peut soutenir des observations a�riennes � plusieurs centaines de m�tres d’altitude et comment le syst�me dirigeable vise � combiner stabilit�, rendement et maniabilit�.

G�n�rateur � gaz hydrog�ne pur � marche rapide et continue, mont� sur un chariot et reli� � un treuil et � une pompe.
Treuil � vapeur avec chaudi�re verticale, machine motrice, et c�blage complexe pour manœuvre du c�ble et r�partition du poids.
A�rostat proprement dit: enveloppe, poche � air adaptable, filet remplac� par une chemise, et nacelle suspendue; technologie visant la r�duction de la r�sistance et l’optimisation de l’h�lice et de la propulsion.
Condenseur par air et syst�mes de chauffage au moyen d’hydrocarbure liquide pour une utilisation prolong�e et s�re.

Id�al pour les lecteurs int�ress�s par l’ing�nierie a�ronautique du XIXe si�cle et l’histoire des syst�mes a�rostatique et dirigeable au service de l’arm�e.

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
