Within the original, suggested francophone titles for this aircraft are "Bi-tri-plan" and "Multimonoplan". Principles are elaborated which can be applied even to monoplanes, though bi- and triplanes are suggested, with a triplane featured in the diagrams. The 175 degree forward edge of the wings facilitates a great ascensional force while the dents towards the rear of the wings diminishes wind resistance relative to forward momentum.

This man, Александр Безобрасов, an army officer and aviator of the Imperial Russian Air Force, whose name may also be Westernized as "Aleksandr Bezobrazov", has some basic data, pertinent to this particular aircraft, available by way of Aleksandr Bezobrazov on English Wikipedia.
