Tom H, the 6G was based on an all up weight of 300kg. It's the maximum for this class of aircraft here in Oz.
I didn't take anything off for the wings, so this test is pessimistic.
All I did was take the weight (300kg) multiplied by 6 (1800kg)
and assume the weight is distributed evenly between two wings (pin jointed structure - no spar carry through to consider)
So divide by 2 wings = 900kg (1980lbs)
It didn't really creak or groan or do anything strange and it reverted to it's original shape as it was uloaded.
By the way, total deflection at the tip was 5cm (under 2 inches), and slightly less than an inch mid way between the root and the strut.
The loading assumed a high angle of attack so 1/2 the weight centred in the 1st 1/4 chord and the other half centred in the last 3/4 chord.
Something I didn't do was do a tilted wing test.
Mainly because it's very difficult to do without introducing an unrealistic twist with the rig we were able to make.
The weight is distributed correctly (as far as I can tell), but it doesn't really represent the anti drag loading that will occur.
There is a large component of the lift force that acts forwards, and the diagonals on this wing design are configured to counter drag (backwards).
What I think I might do is apply gussets to the bottom of the diagonals to give me another shear connection between the diagionals and the spars.
I don't really like relying on epoxy in tension.
Dave Stroud, the straps are all 100 thou 4130, same dimensions otherwise as the plans.
The test was conducted at my friend's house he put in another post in his shed and welded up the test struts - it's his Graham Lee N11 you see in the background - I'm looking forward to seeing that fly soon too!
The engine is a subaru but it's also not mine
Tom XL, the Flaperons I will try and take pics of / describe. They are a total experiment and entirely my fault.
I'm embarrassed to say I haven't weighed the wings. I will post the weight when I've found some scales. I was going to put fuel tanks in and then weigh them.
Not much though.
Thanks for the feedback, all comments welcome!
I'm just working this all out as I go and I would rather someone point out any flaws on the ground before I discover them in the air!
