 the downside is that relatively small power, high fuel consumption and poor performance variable condition. In addition,hogan interactive junior, "Spey" MK202 fans up to five large top cut difficult. The second step is type B, completely abandon the original low pressure fan, redesigned a low pressure compressor, and low pressure turbine matching adjustment accordingly. This is the power advantage of the larger (redesigned for the six low-pressure compressor pressure ratio rises, the air flow rate increases), lower fuel consumption, better performance variable condition, the downside is the need to re-design low-pressure compressor and the high pressure compressor coordination with the original.

 each for a different purpose power generation, fire fighting, oil and the like. After the 1960s, China has learned most of the West is the use of gas turbine aero-engine improvements, because the development costs and the difficulty of the smaller, and therefore China has also carried out research related systems. In 1967, focus on the future development of domestic surface ships, China in the domestic vortex engine on the basis of -8 marine gas turbine power began research and trial spray. According to the ship with the requirements of the designers of the turbojet -8 gas generator more than 80 to modify the design, the new design of the power turbine and various systems, the power of 22,000 horsepower. The complete gas turbine prototype developed in the early 1970s, followed by a large number of tests, in 1974 through an endurance test. Domestic Taihang engine debut, field staff painting debugging.All aspects of speaking, domestic WP-8 change marine gas turbine close Britain's "Olympus" turbine, but in power, reliability, fuel consumption and other aspects of the indicators is obviously inadequate.

 and therefore change with supporting warships, WP- 8 change with the development of gas turbine ship did not go ahead. However, this practice has verified the aeroderivative gas turbine is a better and more economical way, can significantly reduce the gas turbine research, design and verification costs, therefore, in 1983, Chinese authorities decided marine aeroderivative gas turbines mainly used in the future development of guidelines . & Nbsp; & nbsp; & nbsp; Since then, China has developed a multi-type aeroderivative gas turbine, including the original quasi -5 turboshaft engine modifications made 792SB, to turboprop -6 was the foundation of development change turboprop -6 2 A (WJ6G2A).

 so more suitable for conversion into marine gas turbine, such as the UK developed the "Bay" series based on it gas turbine, became HMS 80 years after the main power system, and exported to Japan, the Netherlands and other countries. In view of this, the Chinese authorities have decided to develop a new generation of aeroderivative gas turbines on the basis of the turbofan -9. Aeroderivative turbofan gas turbine model GD-1000. According to information, the development of GD-1000 gas turbine took two-step approach, the first step that is type A, the engine of the original low pressure fan for a top cut at the appropriate radius area, and the low-pressure turbine for the corresponding match Adjustment. This advantage is that the structure of inheritance and strong low-pressure compressor, the workload is relatively little modification.

 change turboprop -6 4 A (WJ6G4A) and 409 type, with modifications based turbojet -6 -6 turbojet change (WP6G), to turbofan 9 (made "bay") is a derivative of the original machine and to change turbofan -9 1 A (WS9G1A) and 410A (G2) and other gas turbines. 409 type is China's first aero engine turboprop derived marine gas turbine. In 1974, in order to derive the aero-engine turboprop -6 409 ship gas turbine project introduction, intended for 077-type minesweepers active force, in 1982 to equip 722 hovercraft. Focuses on design modifications, according to the Navy hovercraft tactical and technical requirements and characteristics of the original single-axis to turboshaft engine turboprop, that the original machine disengaged third stage turbine, which was changed to power turbines; based on the calculation results of the analysis , adjustments to the original third-stage turbine guide vane throat area, so as to meet the high, power matching between the low-pressure turbine; engine intake former axially to radially, axially to the exhaust gas vertically upward, is designed The new intake and exhaust volute; additional engine cooling insulation cover, cabin exhaust ejector system, planetary reduction gear box and diaphragm couplings. 1970s, China from Britain introduced a "Spey" MK202 double rotor turbofan engine, domestic model for turbofan -9. The engine of the second generation of turbofan engine in better performance, plus consider the requirements of carrier-based aircraft and marine environment.

 but the development cycle is too long, combined with the original plan has been adjusted submarine chasers, ultimately failed to use the ship loading. 6000 horsepower gas turbine developed successfully created a precedent for China Marine Gas Turbine, breaking the record of zero, from technology to all the material based on domestic, the accumulation of a set of design, manufacturing, testing, operation experience and technical facilities and tools for Chinese ships with the further development and application of gas turbines has laid a solid technical foundation. Later, the unit in front of the compressor plus 0, 00, the air flow and pressure ratio increases, turn the gas initial temperature up to 1000 degrees, the development of a type of 12,500 horsepower marine gas turbines. At the same time, other domestic manufacturers have developed through the introduction of technology and the introduction of a series of gas turbines.
