FIELD: wind tunnels and channels, applicable in adiabetic compression aerodynamic facilities having high parameters of deceleration of test gas flow.
SUBSTANCE: the piston has a body with guide and seal rings installed on it. A nose section (spherical) with a cover plate on the outer side and a profiled end-piece on the inner side fixed by a ring is installed on the piston body. A cylindrical duct separated from the cavity with liquid by a membrane is made in the piston body. A spring-loaded valve is positioned in the mentioned duct.
EFFECT: protected main components of the facility against destruction at a stroke of the piston in the prechamber in case of emergency.
