Turbine Blade manufacturing process and planning

MANUFACTURING INFORMATION SUCH AS THIS CAN'T BE GIVEN OUT SO I'LL BE VAGUE.

what is the alloy used for high pressure turbine blades?

PROPRIETARY ALLOYS ARE USED FOR THE DIFFERENT STAGES IN THE HP SECTION.

what is the manufacturing process for the above same?

USUALLY FORGING OR LOST WAX/INVESTMENT CASTING.

what are all the process involved in developing the final assembly of the turbine blade? MACHINING, FORGING OR CASTING ARE A SPECIALIZED WORLDS THAT YOU MUST APPRENTICE IN TO FULLY UNDERSTAND.

what was the traditional method followed during early years for developing the turbine blades? WAX INVESTMENT CASTING HAS BEEN AROUND FOR THOUSANDS OF YEARS BUT THEY PROBABLY SAND CAST THEM .

You are not going find more than very general information on the internet in regard to your questions. This is pretty proprietary stuff.

Ya, I work in this industry. If I told you, I'd have to kill you.

Some are seeded with a special sprue and a single crystal of the material which is cooled from that spot to developed a single crystal casting. The specifics of are proprietary.

A very competitive industry.

During my days (early 70's) with a turbine engine manufacturer in Connecticut (providing instrumentation to the experimental test cells), I delivered a CCTV set up (the old Sony b/w reel to reel) to a laser lab that was bouncing laser light off of single crystal blades. Any structural anomaly in the blade/crystal showed distinctly. Neat stuff for a young engineering tech fresh out of school.

If You get the "discovery" channel, They have a program called "how its made" .Recently they showed how turbine blades were made. You can get a copy of the program by contacting the "discovery " channel.

It was quite interesting . uses a lot of specialized machinery. they never tell You what the exact alloy is except its some sort of titanium alloy.

Google Waspaloy and Rene 41 this should head you in the right direction.

i wonder if this is why this didn't develop...
