Single Spar Slotted Wings Next (Apr, 1931)
Single Spar Slotted Wings Next
This drawing represents a well known English aeronautical engineer’s idea of what form the future passenger plane should take. The variable camber wing is not yet possible for engineering reasons.
How similar is this to the currently-used leading and trailing edges that move to change lift for take-off and landing?
Although of course the details differ greatly, this does look like a form of the flaps used on virtually all aircraft today. It especially reminds me of the wings on so-called STOL aircraft:

You want one flap to translate forward and down of the wing with a gap between it and the wing leading edge, and the other to translate aft and down, again with a gap between it and the wing trailing edge. With everything out the area is increased and the wing can then go to a higher angle of attack without stalling. This arrangement looks more like a triplane.
