Do you need an extra­or­di­na­ry solu­ti­on – not just a compromise?

In avia­ti­on even the tiniest fault can be the cau­se of a big cata­stro­phe. This is why we are very well awa­re of our gre­at respon­si­bi­li­ty to pro­vi­de excel­lent qua­li­ty and sus­tained relia­bi­li­ty with our solu­ti­ons. Thus, it is insuf­fi­ci­ent to just meet the gene­ral­ly accep­ta­ble qua­li­ty stan­dards, we would rather aim at excee­ding them time and time again. For pre­cis­e­ly this reason, our tar­get is to find even more effi­ci­ent solu­ti­ons with ever incre­asing advan­ta­ges for all our customers.

In par­ti­cu­lar whe­re the pro­duc­tion of air­craft engi­nes is con­cer­ned, the demand to redu­ce con­sump­ti­on acts as the dri­ving power for inno­va­ti­on. This demand can exclu­si­ve­ly be met by a reduc­tion in weight along with an increase in efficiency.

This situa­ti­on has pro­vo­ked the use of high­ly deve­lo­ped, light-weight, heat-resistant mate­ri­als and the com­bi­na­ti­on of indi­vi­du­al com­pon­ents, con­se­quent­ly a reduc­tion of fits and joints. Owing to hig­her speeds, espe­ci­al­ly cir­cum­fe­ren­ti­al speeds, as well as three-dimen­sio­nal bla­de con­fi­gu­ra­ti­ons, this increase in effi­ci­en­cy cau­ses grea­ter demands on com­po­nent performance.

The chal­lenges men­tio­ned have led to the deve­lo­p­ment of blisks, com­pon­ents whe­re func­tions have been inte­gra­ted to a high degree to replace the fit­ting of indi­vi­du­al blades.

Advan­ta­ges of using Blisk

• No joi­ning of bla­de foot and disk
• No moun­ting
• No influence of a pos­si­ble joint on com­po­nent beha­vi­or, for exam­p­le owing to cen­tri­fu­gal forces at high speeds
• Increased effi­ci­en­cy of the turbine
• Lon­ger com­po­nent life, as no cracks can form at the bla­de feet
