ABSTRACT:
A buoy capable of being dropped onto water from an aircraft, comprising a balloon which inflates during the descent through a forced intake of air through adjustable openings at the base of the balloon. Inside the balloon there is a flexible membrane allowing the air to enter through holes, the balloon remaining inflated to the maximum pressure encountered during the descent. Pockets with openings are traversed by the air and prevent the balloon from rotating during its descent.
