nuclear submarine [2]

Underwater warship that operates on nuclear energy; it can remain underwater for months without surfacing.

conning tower

The submarine’s superstructure, from which the periscopes and antennas emerge.

sail plane

Adjustable fin at the front of the submarine; it is used for diving and surfacing.

diving plane

Adjustable rudder at the stern that allows the submarine to dive and surface.

upper rudder

Movable part that allows the submarine to stay on course and turn right and left.

propeller

Device with blades that is connected to a propeller shaft; its movement generates the propulsion needed to drive the submarine.

torpedo room

Room that houses the torpedoes and firing tubes.

firing tube

Chamber that houses the torpedoes for firing.

torpedo

Self-propelled weapon containing an explosive charge that is designed to attack enemy ships and submarines.

reactor

Device in which nuclear fission is produced; this releases the heat required to evaporate the water in the steam generator.

nuclear boiler room

Room that houses the reactor.

electricity production room

Room where the instruments that produce electricity are housed.

main electric motor

Engine that drives the propeller; the turbo-alternator supplies it with electricity.

engine room

Room that houses the electric motors.

emergency electric motor

Motor that replaces the main motor in the event of a breakdown.

turbo-alternator

Device that uses steam to convert the mechanical force generated by the rotation of the turbine into electricity.

airlock

Hatch that serves as a passage between the outside and the aft area of the submarine.

propulsion machinery control room

Command station for the engine room.

steam generator

Device in which water is converted into steam using heat from the cooling system; it powers the turbo-alternator.
