Abstract
The optimum conditions of use of the high explosive blasts in tubes with air for technology and modeling were researched. The experimental studies and calculations parameters of the direct, reflected, and outgoing shock waves at blasts on the open and closed ends of the tubes of different lengths and diameters were carried out. Comparisons the parameters of shock waves in tubes and at contacting blasts were conducted. The possible advantages of the use of explosives blasts in the tubes as compared with the contacting blasts in a variety of technical applications were investigated.
Highlights
Blasts of explosives in the tubes were made for work out the methods blast stamping and determining the dynamic strength of metals and alloys, modeling of mechanical loads on the barriers caused by irradiation pulse high-power lasers on the plasma modes and of blast rocket engines
The results of the measurements are shown in tables 1, 2 and figures 3-5, where introduced the following notation: I – impulse of reflected shock waves determined from the pendulum deviation in Ns, I/m - relative impulse in m/s (“relative” indicating relative to m - mass of explosive), J = I/S - specific impulse in Pa⋅s, ΔPM – overpressure of reflected shock wave measured on pendulum by sensor in MPa. ∆Pm, τ+, J+- overpressure, duration and specific impulse positive phase of the shock waves were measured by piezoelectric sensors at outlet tubes without the pendulum

Summary
Blasts of explosives in the tubes were made for work out the methods blast stamping and determining the dynamic strength of metals and alloys, modeling of mechanical loads on the barriers caused by irradiation pulse high-power lasers on the plasma modes and of blast rocket engines. Due to increase efficiency of operation the blasts in tubes it possible to abandon of the blast basins and chambers, simplify the manufacturing. These applications usually used brisance action of contacting blasts [1]. Analysis of blast waves for the detonation propulsions was investigated in [3] Those works are devoted both to the creation and use of a small - size reactive blast complex. Study the effect of properties of the source on the action of blasts in air and modeling of impact
