The wings on the Pelican look extremely small for the weight they have to provide lift for, and using the thrusters would get costly. So is it possible that the actual hull of the Pelican provides most of the lift? [http://en.wikipedia.org/wiki/Lifting_body Lifting Bodies] arent new - the general shape and layout [http://en.wikipedia.org/wiki/Image:X24.jpg look ''very'' similar]. The wings would just be for directional and altitudal control, with the thrusters as backup. The Space Shuttle has wings, even though it's a lifting body. Does this deserve inclusion?

*Flight isn't necessarily linked to lift if you put big enough engines on a brick it could break the sound barrier in level flight... control would be a bit of an issue though. Really any time you see a modern fighter stand on its tail and accelerate straight up you’re seeing the triumph of thrust over gravity same with a rocket. The Pelican is likely relying largely on this principle the simple fact it can ''hover'' with a full load is fair evidecne of this. Hovering is purely a question of thrust as no air is moving over any lifitng surfaces. (which is why it's so damn hard) the Pelican can do this which means it has enough thrust to basiclly hold itself up under earth gravity without any lift. | *Flight isn't necessarily linked to lift if you put big enough engines on a brick it could break the sound barrier in level flight... control would be a bit of an issue though.

If it can do that it ought to be able attain level flight easily IMO and the vestigial wings and limited aerodynamic shaping we are probably largely an attitude control measure that works in combination with the vectored engine pods. The fuselage doesn’t strike me as very lifting body like less so on the HCI which is more angular lifting bodies are all very smooth, flattened, and quite wide with large undersides the Pelican doesn’t really resemble them IMO with it’s fairly narrow body, high set wings, and tapering stern plus the stuff sticking out of hanging off the bottom (guns, missile pods, 60 ton tanks...)would ruin the carefully directed airflow needed to make this sort of thing work. | |||
