Compound wing for aircraft, with wing panels staggered to promote lift.
As in Wragg's previous patent family, he states here that the invention could apply to LTA as well as HTA (but it's a bit of a stretch, as the concept relates directly to aviation, airfoil, lift, etc.).
- Note that this patent was administratively delayed for an unusually long time.
- Inventor location (imputed from HistPat): Melbourne, Victoria, Australia
