This patent almost definitely falls within one of the patent families of Adolphe-François-Joseph Doutre. More may be determined as we proceed. That the patent has to do with the equilibrium and stability of the airplane is extrarodinarily likely. Whether these ends were furthered by way aerodynamics or by way of the gyroscope is a matter to be determined relative to the inventor's varied body of work as we gather more information.
