a Design offered by I.I.Volovskim. Load-carrying capacity and range of flight
| to Pass to sections: a Design offered by I.I.Volovskim The conditions Favorable for work, well equipped factory workshops, technical structure and the money resources given in the order of Sikorsky, have allowed RBVZ to construct in a short space of time the whole series of new types of airplanes. îòçûâû ôüþæí Simultaneously in Rowing port at skilled aviation station of Sea department hydroairplane С-5 which at once has yielded good results, especially on ease of launch from water, in comparison with hydroairplanes of Farmana in parallel tested in the same place, Brege and Curtis was tested. The Project ' the big device ' has been presented Sikorskys Pravleniju RBVZ only in the end of 1912 |
in May, 1912 Sikorsky-6 ' (С-6), and in the summer - the second copy of it biplana and monoplane С-7 has been constructed biplan '. The last dvaapparata have been written down on competition of military airplanes on which, despite rather adverse conditions of weather and bad airdrome, they have fulfilled all requirements of competition and ' the six ' has won the first prize. 
Load-carrying capacity and range of flight were an Achilles' heel of dynamic aeronautics: on these parametres dirigible balloons still made a competition to airplanes. The aviation technics quickly progressing in general, in this respect was at a stop: when records of speed poletai lifting heights were beaten almost daily, established by Sommerom on March, 24th, 1911 in Djussi a record of the load-carrying capacity consisting in flight on distance of 800 m (!) with loading in 653 kg, long time remained unsurpassed.
