FIELD: physics, measuring.
SUBSTANCE: field of use of the present invention preferentially in sea seismic prospecting. Seismic pneumoradiator contains the memory cabinet cyclically sealed from a surrounding medium by the fan sealing device, containing a pack of elastic polymeric disk plates figured a lateral view and obturating it at each working pressure only one of plates radially.
EFFECT: decrease in quantity of frictional force of connection failure at start of radiator for increase of accuracy of the opening moment, and also increase of seismic efficiency of radiator at expense of magnification of sectional area of exhaust window.
