German term

straken

German to English Tech/Engineering Aerospace / Aviation / Space turbine blades
This term crops up in several forms in a set of technical specifications for turbine blade design: here are a few examples - "Strakende Schaufel" (heading, no context) "die Schaufel strakt nicht", "Strakende Schaufeln sind wichtig...." I can find several references to the German term on Google but am unable to locate an English equivalent in any reference works.
The text is strictly confidential which means that I am unable to give much context here, but will try to provide more if the above is not enough.

Again in my FR-EN-DR aerospace dictionary:
EN strake = DE Bodenleiste...

I also found (for the wings)
EN overall profile = DE Aussenstrak
and Innenstrak for inside profile

Thanks Frédéric - something like that would seem to make sense in this context. The text I'm translating dates from the 1980s, so this certainly isn't a new term.
Guereau Jun 9, 2011:
Maybe you could use some word as "tracking" or "alignment" as used in the case of propellers?
Guereau Jun 9, 2011:
In line with Alison's finding, according to my old Aerospace Dictionary: Strak = profile, Strakmass = profile size (dimension)

Louise Gough (asker) Jun 9, 2011:
Thanks, Alison - that makes sense in this context...but what would an English-speaking engineer call it?
Alison MacG Jun 9, 2011:
Did you see this definition? 17. Ein Schaufelprofil wird als strakend bezeichnet, wenn es in radialer Richtung keine unerwünschte wellige Oberfläche aus der Kombination der Profilschnitte über der radialen Fädelachse aufweist.

strake

I found this by chance while looking for something else. I had found "Strakwinkel" translated as "hade angle" in Oppermann's Dictionary of Modern Technology, although this is generally a geological term. However, while reading through a piece of literature relating to wind turbines where the term "haded" was actually used, I also noticed a reference to "straking". Extending my search further, I found the term "straked bladelets" in http://www.technology-market.eu/partneriai/Profiles. The term strake is also to be found in http://www.dtic.mil/cgi-bin/GetTRDoc. Taking into account the similarity between "Straken" and "strake" I am wondering if this could be the answer you are seeking.
Note from asker:
Many thanks, Patrick - the term "straking" seems to be more common than "hading", although both are relevant. I did some further research on this basis and found a succinct definition in this 1968 document: http://www.dtic.mil/cgi-bin/GetTRDoc?Location=U2&doc=GetTRDoc.pdf&AD=AD0681291: "Straking is defined as the subdivision of large areas of uniform thickness into smaller pieces of sizes obtainable from a steel mill."

Note from asker:
Thanks, I did see that - but I can't work out how it relates to the way in which the word is being used in this context. It looks like a straightforward verb for which there ought to be an English equivalent.
