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.
