To improve specific power as well as heat efficiency of a gas turbine effectively utilizing air compressed by heat exchange by controlling ship floating exhaust injection device and the like by injection of exhaust such as superheated steam.

Air is forcibly sucked, combustion gas and superheated steam is forcibly injected, and they are used for various kinds of ships for floating the ship and for obtaining propeller force. In a steam engine integrated engine, as superheated steam and combustion gas are injected and it is necessary to obtain propeller force while floating the ship, various kinds of steam gas turbine integrated engine serving a major part as all moving blade steam gas turbine or a steam turbine. The various kinds of power transmitters is switched from use of various kinds of normal power transmitter including compensation into use of development of various kinds of magnetic frictional power transmitter in order. As a control device is used in the case where every devices are used, various kinds of control devices which have become publicly known is used.
