the relevant plant hire proposed starting type intercooler (IC) gas turbine,air max italia, its biggest advantage is to avoid the two key technologies and the power turbine regenerators adjustable guide vanes, the system is relatively simple, low technical risk, can significantly shorten development cycles, reduce development costs,Scarpe Nike Air Max Prezzo Basso, but also on the overall performance has risen, in particular, can quickly provide advanced engines 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, set up a Chinese self-developed intercooler between the UGT-25000 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,nike air foce one, 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.
validated the intercooler heat recovery technology used in a gas turbine, and has since completed a GT-1000ICR Applications on the gas turbine and gas turbine research FT-8 ICR technology to complete the program certification, cycle analysis,scarpe nike online, research design Performance computing and other subjects of the new century after the gas turbine has been applied for the QC185 ICR technology research program. These are the Chinese side laid the foundation for the development of gas turbine ICR In addition, China in the key components of the gas turbine has also made a breakthrough. According to overseas information, relevant Chinese units have developed a gas turbine with intercooler for the development of inter-cooled regenerative gas turbine has laid a solid foundation. Domestic inter-cooler heat exchanger by a key member of the core and other components, the main material for copper-nickel alloy and other non-ferrous materials, applied to a new generation of gas turbines can be increased after the intake pressure, intake air by increasing the round robin, you can not change a substantial increase in the total power and efficiency of the original case of the basic structure of the gas turbine. Another key device in the regenerator, the Chinese also have made a breakthrough. From overseas reports,nike air jordan, the domestic gas turbine regenerators and WR-21 gas turbine regenerator roughly, are plate-fin heat exchanger.
made of stainless steel, the system by the heat exchanger core, into the exhaust duct and branch Shan system components, high temperature turbine exhaust gas from the upper into the lower kind of. The advantage of this regenerator is compact,scarpe nike air max, small size, light weight, low cost, for a limited internal space is very valuable military ships. In addition, its unit area of heat transfer surface, high heat transfer efficiency, and its special structure allows hot gases inside the tunnel to create a strong turbulence, continue to disrupt the thermal boundary layer,nike air max italia, thereby reducing resistance,nike sito ufficiale, improve heat transfer efficiency. Of course,nike air jordan, it also has shortcomings,air max outlet, mainly the internal structure is complicated, manufacturing, welding more difficult, addition is narrow passageways, prone to leakage and clogging,nike air max outlet, cleaning and troubleshooting is also more difficult. From the information "Machine Design" NPO disclosure, the Chinese at the time of the development of UGT-25000 / DA-80 complex cycle gas turbine took more prudent approach,air max outlet, the Navy requested the maximum extent inherited Parent Engine gas generator Flow part,scarpe nike air max, to maximize reliability inheritance (especially high temperature components) Parent machine parts in order to safeguard security survey after the Navy gas turbine array aspect of versatility. In the development of the method.
low pressure turbine and power turbine expansion work, separately driven high and low pressure compressor and the load . Compared with the simple cycle, intercooling cycle through the intercooler reduces the high pressure compressor inlet temperature, thereby reducing its consumption of compressed air power,nike air force, thereby increasing the engine output. According to the Ukrainian side of the argument,air jordan milano, the improved power increased from UGT-25000 40,000 horsepower to 50,nike air jordan,000 horsepower, thermal efficiency from 37% to 40%,nike free run 3.0, within a period of time to meet the recent and future needs of the Chinese Navy's new ship for advanced power systems. But fundamentally speaking, is the direction of the gas turbine ICR technology development. Compared with the IC technology.
higher efficiency ICR technology (WR-21 thermal efficiency can reach 45% higher than the UGT-25000IC 40%),nike free run 5.0, especially at low efficiency working conditions are improved.
