German term

Blattanschlag

German to English Tech/Engineering Aerospace / Aviation / Space Helicopters & Rotorcraft
Context:

"Montage des Dornes im Blattanschlag"

This is about a rotor blade in connection with a weighing system for weighing rotor blades (cf. http://www.proz.com/kudoz/3608611 ). I'm also not 100% certain about 'Dorn', although it assume it is most probably a mandrel.
Proposed translations (English)
3 blade connection
2 rotor limit stop
2 -1 reed beat-up

Discussion

Bernd Runge Dec 18, 2009:
shock absorber Yes, that is definitely a shock absorber or damper. Now just one question: What would a damper in the hub section do in a hingeless/rigid rotor design? Hmm ... Just not what I would have expected.
Gunter Prediger Dec 18, 2009:
helicopter blade David - thanks for the clarification - the darker grey part shown in the photo is the damper (if I recall correctly) and it is a hingeless rotor. Now - what exactly was the question ?
David Williams (asker) Dec 18, 2009:
Thanks Gunter This is for helicopter blades, and it does look like that, e.g. like the darker grey part of the blade protruding into the top right of this photo: http://www.webrotor.de/ec_kopf2.jpg
Gunter Prediger Dec 18, 2009:
David - Your note Rotorblades for windturbines do not have any hinges like helicopter blades have (that is the first generation of helicopter blades - the more advanced helicopters have a hingeless rotor). The term root (Blattwurzel) is used for the heaviliy reinforced section near the hub, this is the area with the highest loads.

for Kugel, Langenscheidt Technik gives allg> (kugelförmiges Objekt) • sphere; globe
--------------------------------------------------------------------------------
f <tech.allg> (Bauteil; eher klein, z.B. in Kugellager, Rückschlagventil) • ball
(I think you forgot that ball bearing is Kugellager)
David Williams (asker) Dec 18, 2009:
Many thanks How about a "Dorn mit Kugel"?
i.e. "Die blattspezifische Schere mit dem blattspezifischen Dorn mit Kugel an den Wiegebalken montiere bzw. auflegen."
Is that a mandrel with a ball bearing?
Jon Fedler Dec 17, 2009:
For 'Dorn' - industry and engineering - mijnwoordenboek gives:
broach, arbor, mandrel, ram, boom attachment
Bernd Runge Dec 17, 2009:
Rotor blades usually have a "rotor hinge" (Blattanschlag) at the end which is connected to the hub components via vertical and/or horizontal "hinge pins" (Dorn).
Jonathan MacKerron Dec 17, 2009:
for Dorn Ernst proposes "core rod" - perhaps Blattanschlag means that the blade is somehow secured before this operation is started

blade connection

If the question concerns "Blattanschlag" I suggest blade connection as a trans for Blattanschluss. "Montage des Dorns im Blattanschlag"
probably refers to a device for lifting/turning the blade during the weighing operation (since the blade is not mounted on the hub yet).
Mandrel would be a good term for it - as you suggested. The photos you have may give you a better idea on what shape/size this "Dorn" has.
Note from asker:
Yes, indeed, that may well be. It looks like the connection of the blade to the hub, although without any hinges (so may be the connection to the hinges). On the drawing (which doesn't have any indication of scale) the Dorn look like it is probably the same size as the retention bolts used to connect it to the helicopter. Maybe it's the root?

rotor limit stop

One possible (and literal) translation.
I'm unfamiliar with the subject matter and not sure if this device ios in context here.
One example of many on Google:
ELASTOMERIC HELICOPTER ROTOR HEAD WITH DYNAMIC AND e.g. STATIC BLADE ...

A rotor according to claim 1 and including a coning limit stop member connected to said hub and having a selectively shaped surface positioned to intercept ...
