A submarine has usually in or on its rear part a direc
tion ?n or rudder and a depth or elevator ?n, the opera
tion of the latter being coupled with that of submersing 15 blades of the screw and form thus a kind of turbine. It is
also possible to maintain the conventional structure of the
submarine vessel; in this case the motor is rigidly ?xed to
the frame and its single screw is connected to the motor
without the interposition of a universal joint or the like;
the direction of the liquid current or jet is effected by
bars or hydroplanes in front. The task of these rear con
trols is to de?ect the current of water, created by the
propulsion system, consisting of one or several screws
which may sometimes operate inside open channels in

sible to direct the vehicle both in the lateral and vertical
