Zabudsky, Nikolai Alexandrovich

Born in 1853 . Pupil of the Nizhny Novgorod military gymnasium . He graduated from the Mikhailovsky Artillery School , from where in 1872 he was released as second lieutenant to the Kronstadt serf artillery .

After graduating from the Mikhailovsky Artillery Academy in 1877, Zabudsky was left with her tutor. To improve in mathematics, he was a volunteer at St. Petersburg University , during a scientific trip abroad, he was a student at Berlin University and attended lectures at the Sorbonne in Paris .

After defending in 1880 the dissertation "On the canonical equations of motion and differential equations of motion of an elongated projectile, taking air as a disturbing cause", he was approved as a full-time teacher at the Mikhailovsky Artillery Academy, and in 1890 became a professor of ballistics; since 1900, he was a distinguished professor there, and since 1908, an honorary member of the conference.

In 1911, the Paris Academy of Sciences elected Zabudsky for his scientific work on ballistics as his corresponding member in the mechanics section.

In addition to scientific and educational activities, Zabudsky since 1877 worked in the field of artillery technology - at first as a receiver of the new material part of the field artillery introduced then 1877 , and then - since 1879 - he was a member of the artillery committee. In this committee, in 1892, he took up the post of permanent member and was engaged in the development of ballistics issues, the design of artillery pieces and shells; at the same time he took an active part in various issues related to the improvement and development of the material part of artillery. Since 1902, Zabudsky was the chairman of the commission at the Main Artillery Directorate for testing new models of artillery guns.

In 1912 - 1914 - Chairman of the economic-building committee for the construction of the central scientific and technical laboratory of the military department.

Killed by rebels in Petrograd on February 27, 1917 during the February Revolution .

Per Zabudsky owns a large number of outstanding scientific works on mathematics, mechanics and ballistics, as well as articles on the material part of artillery:

• “On the solution of the tasks of mounted shooting and on the long-range angle” ( 1888 ; Zabudsky was awarded the Dyadinsky Prize for this work);
• “On the angular velocity of rotation of an elongated projectile” (“Artillery Journal”, 1891 , No. 1);
  • German translation: Archiv für die Artillerie und Ingenieur Offiziere (1892);
• “On the pressure of smokeless powder gases in a canal channel” ( 1894 ) - the results of experiments carried out by Zabudsky together with General A. A. Yakimovich with the aim of determining pressures in different sections of the canal channel (theoretically awarded in 1897 were theoretically processed). Great Mikhailovsky Prize );
  • English translation: "Proceedings of the United States Naval Institute," v. XXI, No. 3 (1894);
• “On air resistance for high projectile speeds” (The Artillery Journal, 1894 , No. 4, translated into major foreign military technical journals);
• “External ballistics” ( 1895 );
• " The theory of probability and its application to shooting and shooting" ( 1898 ) - a lecture course delivered by Zabudsky at the Mikhailovsky Artillery Academy (for both last essays, the General Dyadin Prize was awarded in 1898);
• "Des propriétés générales de la trajectoire dans l'air" (in the Italian journal La Corrispondenza, t. II, 1901 );
  • Translated ( “On the general properties of the trajectory of shells in the air” ), this work was published in the “Mathematical Collection” (Prince XXII); in this essay, a new property of the projectile trajectory is given, according to which the projectile flight time in the descending branch is longer than in the ascending one, the change in the vertical projection of velocity is investigated and cases are indicated where the velocity of the projectile in the descending branch is not the smallest, but increases to the maximum speed;
• "Studies on the movement of an elongated projectile" ( 1903 ) (this essay with additions placed in the "Artillery Journal", 1909 , No. 3, was translated into German in 1909);
• On the pressure of powder gases in the channel of a 3-inch gun and projectile speeds in various sections , 1914.
