We are a leading Tier One provider of high performance metallic and composite structural engine components. Based on our diverse range of capabilities and close partnerships with the major aero-engine OEM’s GKN Aerospace is well positioned to lead the industry.
Fans at the front of the jet or gas turbine draw air into the engine. In fact for most large commercial airliners, a specific type of jet a "turbo-fan" as pictured is used. In this case only some of the the air is pulled through the engine cycle, the oversized fan at the front blows the rest straight out to deliver more thrust when required, but better economy in flight.
Air that is drawn into the engine is compressed through a series of rotating and fixed blades. Known as "rotors" and "stators" these blades can compress the air by 40 times, and this process generates an immense amount of heat.
The compressed and hot air is mixed with fuel and ignited in the combustion chamber. The mixture is carefully controlled to ensure that there is a constant flame. The burnt gases expand rapidly and move to exit the engine.
Before the expanding gases can exit the engine they flow through the turbine. The turbine consists of further blades and these gases spin them and the central engine shaft as they exit through to the exhaust. The shaft spins the fan blades at the front of the engine drawing in more air air and ensuring the process continues.
Our manufacturing capabilities include key technologies like forging, electro chemical milling, high-speed 5-axis machining, assembly and balancing of critical components.
Our products range from metallic fan blades to shafts.
Booster & Compressors
We are a proven leader in manufacturing compressor rotors, compressor and turbine blades and vanes, blisks and integrated bladed rotors using electro-chemical milling (ECM) technology and high-speed 5-axis machining.
We are responsible for the complete design, development, manufacture, assembly, certification and technical product support for the RM12 engine used in the Gripen C/D fighter.
We work closely with our customers to ensure low cost operation and flight safety. The engine is currently used by the Air forces of Sweden, Czech Republic, Hungary, Thailand and South Africa.
From the beginning, we have participated in the European Ariane launcher programme with the production of the thrust chambers for the Viking rocket engines and the Vulcain rocket engines.
GKN Aerospace’s involvement is set to continue with the development of the new generation Ariane 6 rocket. Engineers at GKN Aerospace are in the most intense part of the development phase on a new nozzle for the Vulcain 2.1 engine using the latest technology like laser welding and additive manufacturing.
