Hervé proposes a new model of captive balloon, using design principles for aerodynamics and stability which have been applied in the world of free dirigibles. His model is tapered-cylindrical, with length three times the maximum diameter.

He cites his published comments in L'AéronauteHervé, 1886, Sur les ascensions maritimes appliquées à la météorologie p. 145—regarding "automatic" inflation of a ballonet using the wind.
