Аннотация:Shockwave processes in a shock tube equipped with a high-speed low-inertia electromagneticpneumatic valve are experimentally investigated. Graphs of the pressure sensor signals in theshock tube channel are given. The dependence of the valve opening time on the pressure in the highand low gas density chambers is shown. A physical simulation of the valve operation at the initialmoments of its opening with the formation of a shock wave is carried out.
