what is the symbol?

Bye-bye.

the standard used is the cl ever heard lc..... anyway I think it is only an Italian translation made over the years on the yards deriving from the Anglo-Saxon standard

in the aeronautical sector is very used the term center line because the aircraft is divided into stations, each type of center line has the suffix of the organ that interests, all the axioms and subaxioms are among them indexed e.g. between hinges if we talk about center line hinge and many others.., then even diagrams of all the center line would be the configuration of how will be designed and in future built the aircraft

the bl0 instead we speak building line ie the center line that crosses in a longitudinal way the aircraft and indicates station bl0 where from it will be listed

allego 2 images
foto 1 indicates the center line hinge quoted at 2.50" compared to the center line spar longherone structural
foto 2 indicates the center line hinge and recalls the corners and movements of the hinge going to read the respective notes


greetings

But why do you get angry? non You said that bl doesn't have the same meaning as lc, I didn't contest it.
the yard then was that.
Still don't worry, you're right, okay.
Hi.

p.s.
no thanks I don't come to your archive, I believe you on the word
I'm not mad at you.
it makes me turn the fact that ultimanente does not argue but it just contests, but it is a more "generic" speech.
p.s.: it's not my archive, maybe.

interesting.
So according to you lc (i.e. construction line) would be the Italianization of cl (center line)?
to further clarification, I carry test how indicated on page 22 of the manual of the naval technician - f. cafiero and. 1926."... on the long floor. the profile of the ship is drawn, taking care to place the prora on the right and the stern on the left, this by traditional rule. the drawing begins with drawing a rectangle having a super base. the gallegg in full load; for base infer, l.c., or the base line, and for sides the perpend. "and this also confirms what is said by number 1, that lc or bl, indicate the same thing.
However, I think it is sufficient to explain that it is an element that is located at 690mm from the center line, as they said vale61e sampom.

In fact, to think that we arrived at #24 for something like this leaves me quite interrupted.
It's okay to discuss...
 
I assure you that mechanic comes from the ship
(or at least came if you see the attachment and handwritten and the sheet was used in the 50-60s
there are precise termologies for each sector
a mechanic says 690mm from the axiswhile to differentiate the air force say from the "net dream"but in this sector we must be enlightened by the President
Thank you very much
hi shiren how you are

in the aeronautical sector the word lc construction line as terminology ever heard is about center line as references configurations for assembly as explained previously. . .

690mm the letter to may indicate that it is a reference I have a datum:confused: ???? then the distance and 690mm moving from the referred to towards the lc??? ?

the bl0 is the same lc used in the ship that I do not know as the sector but

ah shiren in aviation is said net trim eeop That is engineering edge off plies if we talk about composite details:biggrin:, would be the engineering perimeter of the particular theorist

Hello, exa...


therefore your lc in the ship would be the bl0 in the aircraft design or the axis that crosses throughout its length longitudinal the ship right? ?

Thank you.

I don't know.
I should see an airplane table to compare it.
But things in common are perhaps more than you imagine.
ordered, longitudinal, the fact of not having symmetry planes except the longitudinal one (for the fuselage or the hull). .
However for the ships, the lc does not necessarily coincide with the line of the keel. in case of trailers, for example, the construction line is horizontal while the keel line takes an angle for which the stern is lower than the prora.
If you're interested in tomorrow I can post a table that clarifies the concept.
In fact, since we are now ot, we can talk about it elsewhere.

I say my experience in the naval field
in many years I have built models for foundry
Primary axes and secondary doors fins rudder straight joints etc etc etc etc.
for each shipshot on the paper drawings there is always a line that indicates how much you are from the ship center that is indicated with cl
when you have to build (I attach an example) a particular
on tracks 1/1 on plywood sheets attached (3110x2110) axis from cl
is fundamental
because you also need to trace the ship garb that would be the steel blades
of the hull
cl is essential for the haul arms in when they compared to cl
have the two axes (in the case of two symmetrical propellers) with another inclination
and with a precise interasse that always refers to the cl
wrong or not have the accuracy of tracking the cl means that there are many odds that the arms with the stick and with them the patts (we talk about several meters)
do not coincide with the bones of the ship

Thank you very much

Excuse me.
I forgot to indicate the naval piece of the design
according to you
that part of the ship is
Thank you.

I would say a section of the housing of the rudder axis, but iron boats I have seen very few, so I am very doubtful.
 
I attach three my tables where you notice:
1) Trailer with lc not coincident with the keel line
2) line ship with coincidental lc
3) Sez. shipwreck with coincidental lc and example of distances referred to it.

Sorry shi, but I can't see how the image looks. I do not distinguish lines and do not read quotas or indications.
 
I'd say it's a stern straight.
but I can't see it well (better than before).
Hi, shi.
Thank you.
 
I have to publicly apologize.
I had a little response over the lines (the n°17) and the thing was rightly pointed out.
Recently some interventions, of which it is not the place or the case that I precise, have upset me but this does not justify me, especially being I a moderator.
I therefore apologize to number1 and all users to "have done it out of the bucket".
Greetings to everyone.

I add a clarification.
exatem is not synonymous with accuracy, infallibility.
much more modestly, it is the first nick name that I was assigned by the telephone manager to my first internet connection. when modems were still used...
other time stuff. :wink:
