(This is a dirigible with a conically-shaped propeller situated in front. It is designed so as to prevent air from circling in, behind the propeller cone and thus creating drag and resistance on the mass of the balloon itself. The aircraft also features a trussed beam nacelle with an "abdominal ridge" carrying the transmission and the aviators and drawn very closely to the balloon, a distancing and isolation being nevertheless complete between the motor and the mass of hydrogen. This construction also facilitates the inclusion of a detachable, and self-propelled, canoe, in the event of calamity at sea.
(Differently put, it is a fairly simple system of rods (or "beams"), seemingly four in total, ranged perpendicularly and fitted appropriately with gears, which allows for the situation of the propulsive motor within the nacelle-canoe. It is this arrangement which facilitates both the possibly needed self-propulsion of the canoe and the distancing of the combustion from the flammable gas.)
