FIELD: blasting operations.SUBSTANCE: pulse detonation plant to create traction power comprises a housing in which a mouthpiece is mounted with a semi-closed detonation chamber, a system of oxidant supply. The detonation chamber is made in the form of a hemisphere of the constant volume, in which walls the nozzle for injection of liquid fuel and a spark plug for igniting a combustible mixture are installed coaxially to each other. Between the detonation chamber and the mouthpiece a profiled annular orifice is located, made in the form of an annular gap with alternating grooves located at an acute angle to the longitudinal axis of the plant, directed into the detonation chamber and connected to the system of oxidant supply into the detonation chamber.EFFECT: simplifying the design of the plant, expansion of the operation ranges.1 dwg |
