---- EDITIOIN ORIGINALE DE LA THESE DE CHAPLYGIN - TRES RARE ---- "In 1902 Chaplygin published his famous paper O gazovykh struyakh ( On gas streams ) in which he developed a method permitting the solution, in many cases, of the problem of the noncontinuous flow of a compressible gas. With this paper he opened the field of high-velocity aeromechanics. The method devised by Chaplygin made it possible to solve the problem of the flow of a gas stream if, under the limiting conditions, the solution to the corresponding problem of an incompressible liquid is known. The equations derived by Chaplygin for the motion of a compressible fluid are valid for the case in which the velocity of the current never exceeds the speed of sound. He applied this theory to the solution of two problems concerning the stream flow of a compressible fluid : escape from a vessel and flow around a plate that is perpendicular to the direction of flow at infinity... O gazovykh struyakh was Chaplygin's doctoral dissertation. At the time it did not receive wide recognition... The significance of this paper for solving problems in aviation came to light at the beginning of the 1930's, when it became necessary to create a new science about the motion of bodies at velocities equal to and greater than the speed of sound, and for the flow patterns past them. The basis of this new science, gas dynamics, had been laid down by Chaplygin, who thus was more than thirty years ahead of the necessary technology...".

---- EDITION ORIGINALE ---- RARE ---- "This Russian mathematician and physicist graduated from the University of Moscow, later teaching mathematics there on the recommendation of Zukovsky. Interested in classical mechanics, especially the mechanics of liquids and gases, Chaplygin continued the work of St. Venant on jet streams and contributed to aerodynamics through his studies of wing cross section. Chaplygin's works also enriched mathematics : his studies of methods of approximation for solving differential equations are achievements of mathematical thought".
