Design features of underwater breathing apparatus

The problem of finding and disposing explosive objects in the water areas seas rivers that remain as a result hostilities on territory our country is urgent requires appropriate technical equipment. support (equipment) for performing underwater work, which service with Armed Forces Ukraine, outdated can pose threat to life health sapper divers during performance complex combat tasks regular basis. One pressing issues today transition Ukraine NATO standards. Taking this into account, issue not only transitioning international standards regulate processes development, planning, testing, operation, repair or modernization weapons equipment, but also preservation lives personnel missions an issue. Accordingly, search ways increase safety military diving descents work relevant. purpose study analyze possibility making structural changes breathing apparatus (UBA) open circuit ABA type evaluate effectiveness made using composite efficiency index. types UBAs are analyzed, main advantages disadvantages open, semi-closed closed circuits gas supply indicated. principlescheme UBA was considered constructive solutions were proposed works. Introducing fundamentally different design reducer reserve air valve scheme will provide opportunity control UBA, work. improve obtained results be used further scientific research direction development promising means
