continue to disrupt the thermal boundary layer,nike air jordan france, thereby lowering the thermal resistance and improve heat transfer efficiency. Of course, it has its drawbacks, mainly the internal structure is more complex, manufacturing,air jordan france, welding more difficult, addition is narrow passageways,abercrombie and fitch france, prone to leaks and clogging, cleaning and troubleshooting is also more difficult. From the information "Machine Design" research and production association disclosure of view,barbour france, the development of China at the time of UGT-25000 / DA-80 complex cycle gas turbine to take a relatively conservative approach, require the Navy to maximize inherit Parent Engine Gas Generator Flow Passage to maximize reliability inheritance (especially high temperature components) Parent Engine parts.
in order to protect security survey after the Navy gas turbine array aspect versatility. In the development of the method, proposed by the relevant plant hire starting middle cold type (IC) gas turbine, its biggest advantage is to avoid the two key technologies regenerator and power turbine adjustable guide vanes, the system is relatively simple, low technical risk, can significantly shorten development cycles, reduce development costs, but also on the overall performance has risen, in particular, can quickly provide advanced engine to the Navy, which is very important in a period of expansion for the Chinese navy. Ukraine will improve after the UGT-25000 / DA-80 named UGT-25000IC.
China set up a self-developed intercooler between UGT-25000 The low-pressure compressor and high-pressure compressor, so that air pressure in the compressed air into the Gao before the machine is cooled; air by Gao,air jordan pas cher, after the low-pressure compressor compressed into the combustion chamber to form a high pressure gas after combustion of the fuel blend, the high-pressure turbine, low-pressure turbine and power turbine expansion work, drive the high and low pressure compressor and the load . Compared with the simple cycle, between the cold loop passing through the intercooler reduces the inlet temperature of the high pressure compressor,christian louboutin pas cher, thereby reducing its power consumption of compressed air, thereby improving engine output power. According to the Ukrainian side of the argument, the improved power UGT-25000 increased from 40,000 to 50,000 horsepower horsepower, thermal efficiency from 37% to 40%,giuseppe zanotti sneakers, within a period of time to meet the recent and future needs of the Chinese Navy's new ships for advanced power systems. Fundamentally speaking,christian louboutin paris, however, the direction of ICR technology is the gas turbine development. Compared with the IC technology,barbour soldes, higher efficiency ICR technology (WR-21 thermal efficiency can reach 45%,louboutin femme, higher than UGT-25000IC 40%),christian louboutin pas cher, especially at low efficiency working conditions have improved significantly. According to "Machine Design" research and production association saying, WR-21 gas turbine power under conditions of thermal efficiency of 30% and 100% power conditions roughly, 100% power consumption under conditions of about 203 g / kW / h,parajumpers pas cher, while in 30% When power is 208 g / kW / h, showing the effect is significant. Data Figure: China R0110 heavy duty gas turbine analysis modelTherefore,scarpe hogan donna, "Machine Design" research and production association believes that the future of the Chinese navy may preclude the use of the regenerator.
According to the Ukrainian side of the argument, the Chinese as early as the 1970s began to develop between cold regenerative gas turbine type 401-2, initially validated between the cold heat recovery technology used in a gas turbine,hollister shop online, and has since completed a GT-1000ICR Applications on the gas turbine and gas turbine research FT-8 ICR technology, completed the program certification cycle analysis,louboutin pas cher, research design Performance computing subjects, and then enter the new century has been applied for the QC185 gas turbine ICR technology research program. These are the China Development ICR turbine foundation In addition, key components in a gas turbine China has also made a breakthrough. According to overseas information about the Chinese have developed a gas turbine unit with intercooler for the development of inter-cooled gas turbine heat recovery and lay a solid foundation. Domestic inter-cooler core body heat from critical components and other components, the main material for non-ferrous materials such as copper-nickel alloy, later applied to a new generation of gas turbine inlet pressure can be increased by increasing the round robin into the air, you can not change a substantial increase in the total power and the gas turbine efficiency when the basic structure of the original. Another key components in the regenerator, the Chinese also have made a breakthrough. From overseas reports, domestic gas turbine regenerator and WR-21 gas turbine regenerator roughly, are plate-fin heat exchanger, made of stainless steel, the system by heat exchange core,scarpe hogan uomo, into the exhaust duct and branch Shan system components, high temperature gas turbine exhaust gas from the upper into the lower sample out. The advantage of this structure regenerator is compact, small size,louboutin paris, light weight, low cost, limited internal space for military ships is very valuable. In addition, its heat transfer surface per unit area, high heat transfer efficiency,louboutin soldes, and its special configuration allows the high temperature gas in the internal passage to create a strong turbulence.
