Description

Object of research and development- Technology and equipment for the cleaning, furnishing of surfaces and edges and coating for parts of weapons, military equipment and aircraft units. The purpose of the development is to create technical solutions and technologies for automated equipment, for cleaning, equipping and coating on high-precision parts of LA units. Research methods- methods of mathematical modeling, numerical methods for solving problems of combustion, heat transfer and radiation processes. A method for determining the position of parts of complex shape during thermal impulse processing is developed. It is shown that such a problem can be solved in two stages. The first arrangement of the workpiece is based on the combination of the centers of gravity and the directions of the main central moments of inertia of the thin shells, which coincide with the outer surface of the workpiece and the inner surface of the chamber. The second is to clarify the position of the workpiece using a phi- function apparatus based on the condition of minimizing the mathematical expectation of the distance between the outer surface of the workpiece and the working chamber surface. The method of an equivalent camera in relation to the problems of thermo-impulse processing of parts of complex shape was further developed. In contrast to the previously applied approaches, it is shown that for the application of the method it is necessary to ensure that the centers of gravity and directions of the principal moments of inertia of thin shells coinciding with the outer surfaces of the original and equivalent parts are reduced, with the main central moments of inertia of the equivalent body decreasing relative to the original inversely planes of said shells. A detonation shockwave generator has been developed that uses pre-compression of the fuel mixture, which facilitates the transition to a detonation mode of combustion, both in spark ignition and in direct initiation of detonation
