Have you ever seen such a beautiful aero-engine blade? (Nov 28, 2022)

Original title: Have you ever seen such a beautiful aero-engine blade? Blades are the largest category of parts in aero-engines, which often need to work in extremely harsh environments. Therefore, the processing accuracy and quality of blades are inseparable from the performance of engines. Let's take a look at the charm of "small stature and great strength". Not much to say, first on a wave of beautiful photos to feel ~ Expand the full text Domestic Superalloy Single Crystal Blades for Aeroengin The mastery of single crystal blade technology means that China will greatly improve the production capacity of high thrust-weight ratio engines, and will greatly improve the service life of the original engines. According to the research, every 25 ℃ increase in the temperature endurance limit of the blade can increase its life to three times of the original temperature. Titanium alloy blade Rolls-Royce trent900 titanium alloy blade The rotor blades commonly used in aero-engines are titanium alloys (compressor blades) and superalloys (turbine blades), and the more common compressor blades are mainly Ti-6Al-4V titanium alloys with medium strength and high damage tolerance. Ti-6Al-4V is the most widely used titanium alloy,titanium round bar, which accounts for more than 75% of all titanium alloys because of its good comprehensive properties in heat resistance, strength and toughness, corrosion resistance, fatigue resistance and machinability. Nickel-base superalloy blade Nickel-based superalloys are the key hot part materials (such as turbine blades,titanium seamless tube, nozzle blades, turbine disks, combustion chambers, etc.) For modern aero-engines, spacecraft and rocket engines, ti6al4v ,nickel titanium wire, as well as marine and industrial gas turbines, and are also important high-temperature structural materials for nuclear reactors, chemical equipment, coal conversion technology, etc. Carbon fiber composite blade This composite structure is half lighter than the commonly used aluminum, steel and titanium alloy materials, and has almost the same strength and heat resistance. Ceramic material blade GE Rotating Ceramic Composite Jet Fighter Engine Blade Coating metal and ceramic materials on the surface of turbine blades can improve the heat resistance temperature of metal, engine performance and safety. However, this technology is still in the development stage, but as far as the current development is concerned, this method is reliable. Blade 3D printing technology Reduced scale sample of GEnx engine blade Laser additive manufacturing repair blade Rollo 3D printing technology Aerospace manufacturing 3D printing is mostly based on the use of expensive strategic materials, such as titanium alloys, nickel-based superalloys and other difficult-to-machine metal materials. It can improve the utilization rate of materials, save expensive strategic materials and reduce manufacturing costs. The details are good news for obsessive-compulsive disorder patients.
