What is the difference between a steam turbine, a gas turbine, and an internal combustion engine?
Steam turbines, gas turbines, and internal combustion engines are all types of engines (mechanical devices that generate power). Their ultimate goal is to generate power (for different needs). Their differences mainly lie in their operating principles, sizes, and application scenarios. There is no saying that one is better or worse. Different operating principles The most […]
Welding repair and remanufacturing technology for aircraft engine turbine blades and fan/compressor blades
Aircraft engine blades are in a complex and harsh working environment for a long time, and are prone to various types of damage defects. It is expensive to replace blades, and research on blade repair and remanufacturing technology has huge economic benefits. Aircraft engine blades are mainly divided into two categories: turbine blades and fan/compressor […]
Failure detection and repair technology of aircraft engine blades
Turbine blades are an important part of aircraft engines, with high temperature, heavy load, and complex structure. The quality of inspection and maintenance is closely related to the durability and service life of the work. This paper studies the inspection and maintenance of aircraft engine blades, analyzes the failure mode of aircraft engine blades, and […]
Thermal Corrosion Fatigue Performance and Life Prediction Method for Hot End Components of Carrier based Aircraft Engines
The operating environment for hot-section components of shipboard aircraft engines and gas turbines is extremely harsh. In addition to enduring high temperatures, pressures, and rotational speeds, these components are also subject to the corrosive influences of a maritime environment characterized by high salinity and humidity. Turbine rotor components represent the most critically stressed elements within […]
F-class, H-class, J-class, understanding of gas turbine classification
Basic knowledge of gas turbines Gas turbines are mainly composed of three major components: the compressor, the combustion chamber, and the turbine. The gas turbine cycle is generally called a simple cycle. Most gas turbines use a simple cycle scheme, and only heavy-duty gas turbines use a combined cycle scheme. Due to different historical backgrounds, […]
There is a universe hidden in every turbine blade
The beauty of the universe lies in its mystery and depth. The Milky Way alone contains countless galaxies, stars and dust, far beyond the range of human observation. Did you know that the turbine blades of aircraft engines also contain a “universe” of materials. In this “universe”, atoms and molecules are cleverly combined to help […]
Basic knowledge of aircraft engine blades (1)
Introduction to turbine blades The component with the worst working conditions in the turbine engine is also the most important rotating component. In the hot end components of aircraft engines, the turbine blades are subjected to high-temperature gas erosion and temperature changes during the engine start-up and shutdown cycles, and the rotor blades are subjected […]
Research and application of adaptive machining technology for damage repair of aero-engine turbine blade tips
The repair of damaged turbine blades is of great significance to the maintenance and life extension of aircraft engines. This paper reviews the research progress of the repair technology of a certain nickel-based cast high-temperature alloy turbine working blade, focusing on the repair method of adaptive machining at the blade tip, and deeply expounds the […]
Study on the influence mechanism of thermal barrier coating on the cooling effect of turbine blades of a certain type of gas turbine
In order to obtain the thermal insulation effect and temperature distribution law of thermal barrier coating on turbine blades, a certain type of gas turbine high-pressure turbine moving blade with internal cooling structure was used as the basic model. The cooling effect of high-pressure turbine moving blade with or without thermal barrier coating protection was […]
