Claims (2)

1. Поплавок постоянного давления системы аварийного приводнения летательного аппарата, содержащий оболочку заданного объема, разделенную внутренними эластичными перегородками на две или более секций, предохранительные и зарядные клапаны в каждой секции и элементы крепления поплавка, отличающийся тем, что с целью сохранения давления газа в поплавке постоянным при разгерметизации одной из секций объемы восполнения, образуемые контуром двухстороннего прогиба внутренних межсекционных перегородок, выделены в отдельные внутренние объемы восполнения, снабженные возможностью наполнения газом одновременно с наполнением всех секций поплавка.1. The constant pressure float of the emergency landing system of an aircraft, comprising a shell of a predetermined volume, divided by internal elastic partitions into two or more sections, safety and charging valves in each section and fastening elements of the float, characterized in that in order to keep the gas pressure in the float constant during depressurization of one of the sections, the replenishment volumes formed by the contour of the two-sided deflection of the internal intersection partitions are highlighted in separate internal volumes filling, fitted with the possibility of simultaneously filling with gas filling of all sections of the float. 2. Поплавок постоянного давления системы аварийного приводнения летательного аппарата по п. 1, отличающийся тем, что с целью обеспечения перепада давления между внутренними объемами восполнения и объемами секций, достаточного для придания напряженного состояния оболочке объема восполнения, зарядные клапаны каждой секции поплавка снабжены дросселями заданного сопротивления.2. The constant pressure float of the emergency landing system of the aircraft according to claim 1, characterized in that in order to ensure a pressure differential between the internal volume of the replenishment and the volume of the sections sufficient to give the shell a replenishment volume, the charging valves of each section of the float are equipped with chokes of a given resistance .
