FIELD: vehicles.
SUBSTANCE: inflatable device for aircraft buoyancy, configured to be inflated in case of emergency landing on water, comprises first inflatable chamber (11; 111), made with possibility of inflation from gas source (9) for transition from folded state to inflated state, plurality of second inflatable chambers (21–24; 121–125), each of which is capable of being supplied with gas flowing into the first chamber through at least one supply channel (31–35). Each supply channel is located directly in wall (12) separating the first inflatable chamber from the corresponding adjacent second inflatable chamber. Every second inflatable chamber can be inflated to change from folded state to inflated state. Each supply channel (31–35) contains check valve (8). There is main shell (5) forming an outer wall of the second chambers in an inflated state, and first chamber (11) is placed inside main shell (5).
EFFECT: invention is aimed at expansion of the range of technical means.
