In the event that a submarine in distress can not surface, the submariners have the possibility to wait for the rescue or if the circumstances require it, to evacuate the submarine via the emergency evacuation system. QinetiQ, from the United Kingdom, wanted to conduct evaluation tests of this system at different angles of inclination of the evacuation tower and to measure the forces perceived by the submariners using an instrumented mannequin. The tests also identified potential problems with the exhaust tower’s top hatch operation and the performance of the hood inflation system in the event of an increase in the tilt angle of the tower.
