Nowadays, gas-turbine ship unit (GTU) competes in the Navy with the same purpose by the steam-turbine and diesel on board installation. From which it is distinguished by its compactness and small specific weight, good maneuverability and maintainability, excellent adaptability to automation and remote control. GTP can be used as vserezhimnaya and in combination with diesel and steam turbine power plants ship. NTU is very sensitive to the quality of preparation of fuel and oil, changes in external conditions (temperature, purity, and air pressure), its trouble-free as nor any other installation depends on the precision performance of all operating instructions, as well as the correctness of decisions made by service personnel in unforeseen manufacturers' recommendations situations. During operation of ship gas turbine showed that the mechanics of the ship requires not only knowledge of and compliance with technical documentation, but also the notion of physical, chemical and other processes in the exploited marine installations. Very often, during long flights is often necessary sudomehaniku reference materials related to the operation of gas turbines. Ship Power Plants (SPP) is used to ensure progress ship, in addition to providing all consumers with essential marine energy (thermal, electric, etc.). Ship power plants are classified as by the nature of the fuel used (with organic and nuclear fuel) and by type of motor – internal combustion engines (ICE), steam-turbine unit (STU) and turbine (NTU), as well as combined, consisting of different engine types.

Marine gas turbines of other types of favorably by a number of factors: small size and specific gravity, and simplicity, ship repair, better suited to automation and remote control. Simultaneously, several gas turbines inferior to ICE on the economy and require more care, both during operation and when idle. GTP in a ship's propulsion plant. By appointment SPP full range of mechanisms and systems of suspended divided into four groups: – the main installation, designed to operate the vessel: – supportive, providing the needs of the ship in different kinds of energy in a parking lot in preparation for the main installation action and personal needs of the vessel – the electric power, providing various kinds of electric ship – Vessel arrangements and destination. Gas-turbine ship systems can be major or part of the SPP, can also be driven generators and other machinery and marine equipment. In these cases, called the auxiliary gas turbine. The main machine consists of one or several complexes engine, propeller, each of which includes an engine, shafting and one main installation. Main unit in turn consists of one or more of the same type (in CG, possibly heterogeneous) engines and a common They transfer energy to the supply line through the mover shaft.

If the machines main gas turbine installation, and it provides the speed and maneuverability, it is called a turbine vserezhimnoy. In the combined set turbine, as a rule, is accelerating (afterburner), which provides ship velocity increment Forward. The gas turbine engine, a heat engine that is used to convert the energy of combustion fuel into mechanical work on the motor shaft. The main elements are SGTD compressor, combustor and gas turbine.
