Maîtrisez la direction des aérostats grâce à deux modes d’orientation innovants.
Cette édition présente des systèmes conçus pour diriger les ballons et dirigeables en mouvement, en s’appuyant sur des principes physiques clairs et reproductibles. Vous découvrirez comment des machines légères et efficaces pourraient permettre de voyager avec plus de précision, même face au vent.
Le livre expose, étape par étape, deux concepts d’orientation basés sur des principes universels. Il explique pourquoi des plans inclinés et des moteurs légers peuvent transformer une chute en déplacement directionnel, et comment l’électricité peut servir à contrôler la propulsion et la direction sans compromettre la sécurité.
Idéal pour les lecteurs intéressés par l’histoire de l’aérostation et les bases techniques de l’aéro-navigation.

Paperback. Condition: New. Print on Demand. This book posits that constructing a dirigible aerostat is achievable with the scientific knowledge of the time. It presents two systems to orient an aerostat, addressing the challenge of maintaining a course in an atmosphere subject to unpredictable movement. The first system employs a large, round or square parachute-like plane attached to the aerostat; the second system uses a motor driving a propeller, which can be moved around the central axis of the craft. The author bases these designs on scientific principles and observations of bird flight, arguing that birds navigate by transforming a perpendicular fall into an oblique descent using their wings as inclined planes. The book draws parallels between aerial and marine navigation, emphasizing the need for a motor powerful enough to propel the craft against wind resistance. It concludes that, while further testing is necessary, the principles outlined within provide a path towards achieving dirigible aerostats and unlocking the potential of air travel.
