1、 Introduction to Gas TurbineA gas turbine is a rotary power machine that uses continuously flowing gas as the working fluid to convert thermal energy into mechanical work. A gas turbine cycle consisting only of three major components: the compressor, the combustion chamber, and the gas turbine, is commonly referred to as a simple cycle. Most gas turbines adopt a simple cycle scheme. Because its structure is the simplest and best reflects a series of advantages unique to gas turbines, such as small size, light weight, and fast start-up.Usually in gas turbines, the compressor is driven by the expansion work of the gas turbine, and it is the load of the turbine. In a simple cycle, about 1/2 to 2/3 of the mechanical work generated by the turbine is used to drive the compressor, while the remaining 1/3 of the mechanical work is used to drive the generator. When starting a g...

1、 PrefaceDue to its high thermal power conversion efficiency, heavy-duty gas turbines are the most core equipment in the fields of energy generation and ship propulsion. The development technology of high-grade heavy-duty gas turbines is extremely complex, so heavy-duty gas turbines are also known as the power heart of China's industrial and shipbuilding fields. Up to now, China has successfully developed a 50 MW heavy-duty gas turbine, achieving a breakthrough from scratch for the F-class 50 MW heavy-duty gas turbine. At present, China is increasingly improving the construction of the three major systems of heavy-duty gas turbines, achieving a trinity of prototype design, equipment manufacturing, and experimental delivery. China has also become the fifth country in the world to fully master the design and manufacturing technology of heavy-duty gas turbines. &n...

introduction   Main forms of erosion damage in aircraft engines | Anti erosion coating system for aircraft engines | Coating erosion test system | Conclusion and prospects    1、 The main forms of erosion damage in aircraft engines The erosion damage of aircraft engines generally refers to the mechanical interaction between the surface of engine component materials and the impact fluid, resulting in gradual wear and tear of the material surface. When an aircraft flies over the atmosphere, the forward facing surface of the engine may be affected by different particles or flying objects, especially solid particles and water droplets, which can directly or synergistically cause erosion damage to engine components and shorten their life cycle. These damages include erosion and wear of fan/compressor blades, blockage of blade cooling holes, dust depositi...
