Stepan Karlovich Dzhevetsky: Pioneer of Russian Submarine and Aviation
Stepan Karlovich Dzhevetsky (1843-1938) was a Russian researcher and inventor who made significant contributions to the development of submarines and aviation.
Early Career and Submarine Innovations
Dzhevetsky began his career in the Russian Imperial Navy. In 1879, he launched two of his own submarine designs, a one-seater and a four-seater. These submarines were equipped with mine launchers and powered by human muscle. The four-seater submarine featured an early version of the periscope.
In 1880, Dzhevetsky developed a prototype submarine with an electric motor. Together with Alexander Krylov, he proposed a design for a 120-ton submarine with steam engines, intended for a crew of 12. This design won the grand prize at the 1898 Paris Exposition.
Innovative Submarine Technologies
In 1897, Dzhevetsky invented the underwater mine apparatus, a torpedo launcher specifically designed for submarines. It differed significantly from torpedo launchers used in other navies.
In 1907, a submarine named "Pochtovy" was built according to Dzhevetsky's design. This submarine featured a unified gasoline engine for both underwater and surface propulsion.
Contributions to Aviation
Beyond his work on submarines, Dzhevetsky was also a noted inventor in aviation. He developed the concept of the optimum angle of attack for wings and the conditions for stability in airplane flight. His theories received widespread acceptance at the World Air Congress in 1889.
In 1882, Dzhevetsky was elected Co-Chairman of the Aeronautical Department of the Russian Technical Society. He later moved to Paris in 1892, where he pursued entrepreneurial endeavors.
Literary Works
Dzhevetsky authored numerous publications on his research in both submarines and aviation, including:
"On Air Resistance in Relation to the Flight of Birds and Airplanes"
"Airplanes in Nature: An Essay on a New Theory of Flight""The Theoretical Solution of the Question of Bird Soaring"
"Determination of the Elements of Propellers"
"Theory of Air Propellers and a Method for Their Calculation"
