Yes if you can make it light enough. Any weight in the wings is weight that cannot be carried by the aircraft for passengers or cargo.albert wrote:So in your wing , you would have your main beam , with pistons built into it.
The glide ratio on a 767 configured for optimal glide is an impressive 20:1. By comparison your average sport gliders are 30:1. It's all about tradeoffs. You can't get any aircraft to stand still in the air, so even with a wing with lots of lift, there are physical limits to how slow a big airplane can travel without falling out of the sky. 100 mph in a crash is still a lot of kinectic energy. And there's *no way* a large body aircraft could fly slower than 100 mph regardless of how thick the wing is. Remember that a wing with more camber does have more lift, but it also has a lot more drag. At some point those cancel each other out and the plane falls out of the sky.Might come in handy in the event of a power failure , they can set the wings to the max height and leading edge camber to glide in for a slow landing...
No more deaths in a plane crash..
Gliders can fly slow because they are light-weight and have incredibly wide wingspans and very thin airfoils. Lots of factors. It's neat stuff. But here too, there are actual scientific principles at play here and I wish you were interested in them.
