摘要
The research area of this article lies at the junction of the instrument-making industry and gas dynamics and covers a scope of problems, related to designing the optimal software–hardware architecture for processing data from physical experiments. The work concerns experiments on investigations of highspeed continuous spin detonation processes. The velocity of the detonation wave exceeds the velocity of sound in the medium by dozens of times. A photosensitive line that supports sufficiently high velocities is quite suitable for the optimal video filming of similar processes. However, for working with the resultant data stream it is required to design a software–hardware complex equipped with a largevolume random access memory that implements the controller of the available memory. For this purpose, a device allowing an optimal solution of the formulated problems was created. The paper describes turning points in designing the unit and the experimental results obtained during the final adjustment of the unit. © 2015, Pleiades Publishing, Ltd.
