basic spar construction

[Dave Schneider]

Can anyone suggest some home built construction sites where they show the
process of building a spar for a foam composite wing. I'm confused on how a
spar is built for a foam wing. It doesn't seem like the foam itself would
provide enough structure to provide a web. It would seem like you'd have
to cut the wing foil, cut out the location of the spar, build the spar, and
then reinstert that section back into the foam wing.

Thanks,
Dave

The SkyPup ultralight uses foam spar webs and ribs with
wood for the spar caps and rib caps. There are many pictures
on this website, some will show detials of the spars/wings during
construction.

http://www.skypup.net/index2.htm

For the SKyPup, fisrt the spar is made. The foam ribs are
made in two pieces one fore and one aft of the spar, then
butt glued in to the spar web. Then the rib caps are glued on.

The spar caps carry all the compressive and tensile stress due
to bending of the spar as the wing is loaded. The web only carries
shear due to bending and that is quite small.

Clearly not the only way to do it, nor necessarily the easiest
for every builder.

If you are not familiar with beams, it can be very helpful to
study up on beams, especially I-beams and box-beams as
wing spars are essentially beams.

On the SkyPup site the photos are groups by owner in the 'Kennels'
section. It will take a lot os searchign to find one with construction
details.


Good pictures of the wings and spars are also here:

http://www2.wcoil.com/~rford/

The show the spar and rib construction quite well.

The Sky Pup is made of foam, wood and fabric so it is a composite
aircraft. Most of the time when refering to composite aricraft the
speaker
means fiberglass, kevlar or carbon fiber.

Conceptually, those other materials can be substituted for the wood
in a SKyPup-like design, though ther result might not necessarily have
a better strenght to weight ratio. The wood in the SKy Pup is used
very
efficiently.

Thanks. I finally found the same site after some searching. Pretty neat
little ultralight!

Is there any way to calculate wing loads on something like the following
(this is where I'm going). Do you think the skypup construction could
handle these loads:

Thanks again for your help

Dave:
Take a look at the ruttan wings on a q-1 or q2 it will fit the bill for
what you want. There is one site on the web for free downloads of the q2
info but I do not have the URL at hand. Q1 plan can be had on C.D. for less
than $10 via EBay.

after a bit of surfing i found this. Is something like this what you are
talking about?

http://www.hinkleymall.com/airplane_cd.html

There is also this on ebay:

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=26441&item=4510814564&rd=1


Basic question for the Quickie, do the wings disassemble? I'm also looking
for techniques for attaching wings.

Thanks!

Of course.

The first step is to model or at least establish an upper bound to the
forces acting on it. That may be more complicated for an iceboat
than for an airplane.

Possibly. The iceboat wing may see more substantial torsional
loads than the SkyPup Wing. In general box beams are, in regard
to strength to weight ratio, very efficient for handling torsional
loads.

The SkyPup spars are more like an I-beam than a box beam.

The SkyPup, being an ultralight was designed to minimize torsional
loading on the wings to permit the use of a single spar and keep
them light as well as keeping the construction simple.

Some aircraft use two spars per wing with x-bracing between them
to handle torsional loads. Some use box beam spars. Monocoque
construction which relies on distributing the stress on the skin rather

than carrying it all on internal structure essentially turns an entire
wing into a box beam.

Thank you for taking the time to answer my kind of off topic (non-airplane)
questions! I'm looking into the Quickie wing construction right now.

Dave for Your info. The Quickie and Q2 use a fiberglass build up spar as You
will see from the plans. The Q-200 uses a carbon fiber spar.
Yes the Quickie canard (front wing) can be removed.

Thanks much! There is a lot of good general construction information in
those plans.

Marske Gliders have a few articles on ther website,
http://www.continuo.com/marske/monarch/manual.htm

and here's a somewhat dated article by Jim Marske that'll probably be
very interesting to you
http://www.continuo.com/marske/carbon/carbon.htm

Good luck!

Someone privately emailed me a link to this site, but I missed the carbon
rod article. Those are really cool looking gliders! Thanks for the
links!

A went through the Q1 and Q2 plans this past weekend. Nowhere in the plans
did I see mention of what weight glass they are using for the unidirectional
and bidirectional glass.

I believe that you'll find that, unless specified, they want you to use
RA7715 for UNI and RA7725 for BID. The 7725 (which I think is basically
the same as 7525) is about 9 oz and has a twill weave for good drape.
The 7715 (which I think is the same as 7515) is about 7 oz.

Thanks. I see you are using the carbon rods too. (in reference to a

Bates Engineering has a DOS computer program for designing a wing spar.

I have met him and listen to his forums at Oshkosh many times.

Thanks. The prop optimizer is interesting too. My other interest is
hovercraft. Again, not an airplane, but it does have airplane components
.... and I guess it does fly ... even if it is only inches above the surface.

I have emailed them and asked for the appropriateness of their programs for
my non-standard applications.

Well I bit the bullet and ordered the $95 program. That may seem like a
lot, but Don also wants to verfiy that your using the program correctly.
I'm thinking that the consulting support that goes with the program makes it
a bargan!

Got it, thank you.

I have never seen a Quickie that had a removeable canard or main wing.
( I built the single place, so I'm certain of that.) I have looked at
hundreds of pictures of other Quickies or seen them in person and have
never seen removeable wings. ( Not to say that someone out there hasn't
done it of course, but it's not in the construction plans ) The
fuselage, however, can disconnect aft of the main wing if you would
like to build it that way. It's approved, but take it from me, it's a
nightmare !! I do believe the main wing of the Dragonfly is
removeable, but I'm not sure of the canard.

I've been looking at the plans and didn't see anything removable either.
I'm familiar with the way model airplanes join segmented wings, but I'm
unsure if they do something similar on "real" airplanes.

About the Bates Engineering DOS programs....I have never used DOS and
didn't start "computin" until Windows became the "standard?" Are the
programs such that they can have the required info input into standard
Excel worksheets? If they can, the spar program would be a great tool
to play with in designing an I-beam spar similar to what the Vans
aircraft use.

No. It is a really crude interface by today's standards. It is a very
sequential menu driven interface. By sequential, I mean that if you choose
the wrong base menu item, you have to answer the rest of the sequential
prompts until you get back to the main menu. It gets the job done, and
that's it. I grew up on DOS so it doesn't bother me too much, but I'd
certainly prefer a better interface!

I should also say that the license agreement allows you to use the program
for something like 5 years after which time you'll have to buy the program
again in order to continue to use it. I'm not sure if there is any time
bomb in the program that actually prevents you from using it. I suppose I
could move my clock ahead and see what happens.

Anybody know of any other programs available for designing spars that
will use the more friendly Excel format?
Thanks in advance

I would suggest you grab a college-level structures textbook and make
sure you understand all the inputs that are used...

[Dave Schneider]

BTW: I already mentioned this, but Bates Engineering requests that they
verify that your spar design by sending them output from the spar optimizer.
My application isn't a life or death situation, but the intended use of this
program IS. If I was thinking about building something that actually flew,
I think I'd opt for a proven design and construction method over something
designed by my inept engineering expertise. :-)
