Turbine Engine Blades and Vanes | Collins Aerospace
Our turbine engine blade and vane products include low- and high-pressure airfoils for compressor and turbine engines, as well as vanes, vane rings, shrouds and nozzle segments for aerospace and industrial gas turbine engines.
Why are turbine blades not made out of titanium, only compressor blades?
According to this video on jet engine blades, titanium is never used for the turbine, because it "melts and burns at the temperature of the flame". Only the blades of the compressor are made of this material.
Why do jet engine fan blades have a twisted shape?
2017年7月25日 · Why do jet engine fan blades have a twisted shape? Your question is about fan blade twist, but actually the answer is valid for nearly all rotating blades. If a blade weren't twisted, the angle of attack would be very different from its root to its tip.

2018年3月16日 · These blades, which can be found in many modern, high-performance gas turbines (a.k.a. jet engines)—including the ones powering the F-22 Raptor, and larger electricity-producing...
Aerospace – Turbine Blade - Tungaloy-NTK America, Inc.
A jet engine turbine blade is the individual component that makes up the turbine section of an aircraft engine. The turbine blades are exposed to the harshest environment in terms of pressure and temperature, while rotating at extremely high speed.
Turbine blades and superalloys - WENZEL America
2021年8月10日 · Today we will look at choosing material that will deliver optimal performance, enhancing the chosen material to ensure the turbine blade performs optimally over extended periods of time and then taking it to the next level. Choosing the Material of turbine blades. Jet makers turned to nickel alloys after testing and trying different combinations.
Sixteen high-pressure turbine (HPT) T–1 blade sets were removed from commercial aircraft engines that had been commercially flown by a single airline and inspected for damage. Each set contained 82 blades.
Pratt & Whitney Single Crystal Turbine Blade - ASME
Developed from concept to market to production in less than ten years, Single Crystal Turbine Blades were employed in military jet engines in the 1970s, commercial jet engines in 1982, and in land-based gas turbines in 1995.
How Turbine Blades Enhance Jet Engine Performance
2024年10月24日 · Discover how turbine blades convert exhaust gases into mechanical energy, boosting efficiency and performance in modern jet engines. Learn about precise blade angles, high-temperature materials, internal cooling channels, and future innovations.
Regulators approve new ‘more-durable’ Leap-1A high-pressure turbine blades
2024年12月6日 · US and European aviation regulators have certificated new high-pressure turbine blades that CFM International says will help address durability troubles with Leap-1A turbofans.
jet engine - Turbine blade manufacturing/assembly process
I want to know the process for manufacturing turbine blades and the companies that are involved. Who makes the turbine blades? Who applies the thermal barrier coating? Who repairs the blades? Let's take the General Electric GEnx as an example. Does GE make the blades themselves, or do they buy them from a supplier?
These blades, which can be found in many modern, high-performance gas turbines (a.k.a. jet engines)—including the ones powering the F-22 Raptor, and larger electricity-produc-ing turbines—are grown from a single crystal in a vacuum casting furnace from superalloys.
