[Albert Cassar]

Hi all
   A friend  would like to do a wing load test on his new 
project which is his own design. the wing spa and WAF are the same as the 
KR.
Would he need to have the aircraft upside down and load it with sand bags or 
can it be done right side up.
If so how do you place the bags (eg) equally over the wing or moor wight at 
the root of the wing. 

Thanks in advance.

That being said, there are several good books he can get on aircraft design
and structures that do explain how to design an airplane for the intended
loads.  More importantly, they will help him from the beginning stages of
the design long before he needs to determine if his wings are strong enough.
I am in New Orleans for work the rest of the week and my library is at home,
but off the of of my head I would recommend Dan Raymer's Simplified Aircraft
Design for Homebuilders as a must for general design and performance
calculations although not for structural information.  Stress Without Tears
is good.  Check the book section at www.aircraftdesign.com for others.

Good advice!  I have had a basic course in strenth of materials and know
generally what is invoved but there are nuances(sp) and I would depend on
nothing that I did beyound the simple case and wing loadin is just not all that
simple.  Leave that to the aero engineers.

A question on this wing loading test---

Since the wings are suppurted at the tips and somewhat in the middle
it would appear that the wings are are loaded mor as a simple Beam.

Are not wings loaded more like a cantilever beam and as such take
less of a load to fail them?

KR> Re: wing loading test

[tinya...@aol.com]

Seems like in the 60s there was a lot of homebuilts being flipped over  and 
loaded with sandbags.  I had the thought that it was encouraged by the  FAA, 
even on proven designs.  There have been articles in SA about static  testing.  
Seems like no big deal to me if done right.  I would rather  hear a BANG on 
the ground than in the air.  

Thanks for the recommendation on books to design homebuilt airplanes.   I am 
about to go down that road myself.

The tips are not supported. Look at the gap between
the wing tip and the sandbags on the floor. It is more
visible in the wings farther in the picture.

[StRaNgEdAyS]

If you look really closely at the far wing tip you will see that the
sandbags do not in fact touch this seems likely for the near tip as well,
the gap is simply obscured.. they seem to be there to help keep the test
subject manageably level while being loaded, or to maybe catch something
before it hits the ground when it breaks.
