Good afternoon,
Can you bend a backplate with a wing ?
If you had a wing mounted between a plate and the cylinder or cylinders and you were to inflate the wing , could you bend the plate if the wing had no free space to inflate into ?

I remember something about this from a few years back but couldn't find it.

Thanks in advance,

Yes. I think Tobin tested it once; if you put a single-tank wing onto double-tanks, and inflate the wing, you can bend even a steel backplate. Surprising, to say the least.

I believe you are referencing a case where a singles wing (Not DSS!) was mistakenly sold to a for use on a set of doubles.

If a singles wing is "trapped" between a back plate and a set of doubles it is possible to bend the back plate by inflating the wing because the expanding wing has no where else to go. The inflatable portion of a singles wing extends inside the outline of the back plate.

Very large forces are possible with enough square inches of low pressure gas.

If a single wing is fitted to a single cylinder the wing can expand around the cylinder, and if a doubles wing is fitted to a set of doubles the wing will expand beyond the outline of the backplate, neither will put any appreciable load on the back plate.
