Пороховщиков А.А. Би-Кок / Пороховщиков-2
"Би-Кок", (Пороховщиков № 2, "Двухвостка")
"Bi-Kok", (Porochovščikov no. 2, "Dvojocasý")


This original aircraft can is considered as one of the first attempts to address the issue of construction of the building of aircraft dvojtrupého arrangement. The designer used lightweight boxy beams, covered with canvas, and the engine in a compression arrangement placed on the stern of the gondolas, in which is in position behind placed the two pilots. The Gondola was hung on the beams of the upper wing. It had wings and due to the large margin was reinforced with long struts towards the ends of the wings.

There is thus a machine of very original construction - Bi-Kok represents jedenapůlplošník with the two-cab and dual control, equipped with an engine Gnôme on the performance of 50 PCS. Flat hull beams resulted in two directional kormidly, at the end of each beam one, and dvojplošnými tail surfaces, in the top part with a fixed stabilizing surface, in the lower a fully movable vertical rudder. In addition, the design was for reasons of ground transportation quickly and easily in 5 minutes dismantled, in the disassembled state is "Bi-Kok" gave the save to a shipping container with dimensions of 3.7 x 1.8 x 1.7 m. it Seems věak that the main reason for the occurrence of "folding" the plane was the fact that the designer built in his own apartment, located in the 6. floor of a residential building.

The plane was designed for military use such as reconnaissance/support aircraft corps, therefore it was assumed the installation of armor plating, machine-gun armament or bomb pylons.

"Bi-Kok" passed in the period from 15. August to 5. September 1914, successfully tests. With a full load of 256 kg, equal to practically the weight of the empty aircraft, the pilot Mikhail Leontijevič Grigorašvili (Михаил Леонтьевич Григорашвили (Грегор)) reached a maximum speed of almost 100 km/hr. For aircraft with the engine 50 pieces is such a performance considered really high. By the end of the year, talks were held with Military administration (Военное ведомство) about the production of a smaller series of "Dvojocasých" in the enterprise F. F. Tereščenko (Ф. Ф. Терещенко). But Porochovščikov wished my plane to build personally, in a quantity sufficient for the equipment of one air brigade, which reported to the Military authorities in a personal letter from 8. January in 1915. Further negotiations ended in a blind alley and to construct military "Dvojocasých" Porochovščikova not.

In 1915 he was made a second copy of "Bi-Koku" with the original belt suspension, which can be installed instead of wheels. Crawler chassis was formed celtovým bands, moving on wooden reels. Tests carried out have confirmed the operability of the original equipment, however nothing else around the plane wrong..
