Hi,
Pioneering and military aircraft design. Poland / Russia.
On March 13, 1917,
Ryszard Gumiński asked the Russian Minister of War, Alexander I. Gucchkov, by telegram to commission him by the army to build a new type of steam locomotive and plane.
This request was sent to the Military-Air Fleet Board (UWWF), which passed the information about the locomotive to the Main Military-Technical Board (GWTU). At the same time, on March 17, Gumiński was asked to provide the UWWF Technical Committee with a description and drawings of his plane - necessary to evaluate his offer. Gumiński did not reply to this letter, perhaps he did not receive it. On May 30, 1917, he again telegraphed to the minister of war - already General Kerensky - that the army started building the plane under his direction in the workshops of the Aeronautical Park in Nowa Wieś near St. Petersburg. In a letter to Gumiński of June 5, UWWF asked him not to send the description and drawings of the project to St. the field of aviation technology. At the same time, on June 5, the Aerodynamic Laboratory was asked to evaluate Gumiński's project, if he applied and submit materials, and to provide the UWWF Technical Committee with its findings on the inventor's proposal.
On August 8, 1917, the Aerodynamic Laboratory sent to the UWWF Technical Committee an opinion on Gumiński's airplane (referred to by it as "Kampo"), prepared on June 21, 1917 by Eng. mechanic Władimir P. Vietchikin, specialist in the field of strength of materials and aircraft constructor. From the point of view of mechanics, the law of conservation of energy, the method of technical presentation, wrote Vietchikin, the project is an example of the greatest ignorance. Gumiński determines the center of gravity of the entire apparatus incorrectly. Vietchikin does not know what force will be able to make the plane move, since the author of the project talks about 32,400 engine revolutions / min - about the possibility of ground taxiing at a speed of 17 597 km / h (!), On landing gear wheels powered by an airplane engine through transmission .
Vietchikin emphasizes that the inventor provided a huge number of drawings of unimportant parts of the plane and the engine, disordered and unrelated to each other, in which there are cogwheels, chains, unnecessary shafts of enormous mass and absorbing, without any use, enormous work on friction. They do not show the dimensions, except for the diameter of the landing gear wheels and the propellers, the number of teeth and the wing surfaces. The weight of the camera and the load capacity were not given, and the presented list of materials from which the parts of the aircraft should be made indicate that the author has no idea about the strength of materials (...), as well as everything related to the calculation of engine power and the relationship between force and speed - here he seems to believe in the possibility of obtaining energy from nothing - Vietchikin ends his assessment by saying that both the drawings and the description are as dilettant as the concept of the aircraft, the design of which does not contain any thought deserving attention .
On August 12, Vietchikin's opinion was announced to the chancellery of the minister of war. Gumiński, however, did not accept her. He turned again - this time to the head of the UWWF Technical Committee, Col. Kalinowski - with a request to enable him to build an airplane, this time at his own expense in the workshops of the Aeronautical Park in Nowa Wieś. Kalinowski added a resolution to this letter: at his own expense he can build wherever he wants. In a reply to Gumiński on August 24, 1917, he was informed that UWWF did not have its own workshops for building aircraft in St. Petersburg or anywhere else, advising him to send his order to one of the aircraft factories.
