Application of large airplanes. The main military-engineering management
| to Pass to sections: Application of large airplanes The Engine ' Erlikon ' capacity of 50-60 h.p. Settled down before highly lifted wing. Rotation from it was transferred to pushing screw by means of a long shaft. Aspiring to lower the plane centre of gravity, pilotskie seats I. M.Gakkel has arranged low, at the water. Management was double so both pilots could conduct samoletpoocheredno. This plane did not fly, but Russian technical society was awarded on April, 25th, 1911 By me. M.Gakkelju a silver medal of an exhibition ' for an original design of a sea airplane '. It is possible to notice that the low arrangement nothing of the closed pilots inevitably would lead at water landing to their cold baths, and capacity of the engine for the double plane would be, probably, insufficient. |
In August of this year-yaks Modestovich draws the new plane - biplan ' Gakkel-Iv '. However soon of it the new idea takes hold: it begins working out of the amphibian first in Russia. On December, 4th, 1910 it has been exhibited at the first International aeronautic exhibition at Petersburg. Two hollow wooden bow-shaped beams which displacement kept afloat the device with two pilots were the basic power element of this plane. 
By the spring Jacob Modestovich has constructed also developed in the autumn biplan ' Gakkel-Iv '. The main military-engineering management was ready to buy this ' the two-plan of military type of Russian design ', but pilot D.I.Volkov, is visible at delivery flights, on May, 5th has had an accident, having broken the car. Restoring the plane, Jacob Modestovich has changed its design, having transformed, thus, egov ' Gakkel-Vi '. By this plane it has started to fly itself: whether. F.Bulgakov from D.I.Volkovym did not begin to trust designs of Gakkelja, whether the designer has ceased to trust them the planes.
