bite me; you explain it oh mighty one
anyway, the critical issue is, if i'm not mistaken, that enough air is moving over the wings to create lift; in this case all that air would have to be pulled by the engines, and none of it given by moving forward through the air, so yes, maybe, it could take off, but i would think that the engines would have to be pulling vastly more air, and the air being pulled would have to be dispersed over the wing to provide lift; which of course is the very reason that planes speed up to take off, the air being pulled over the wing because of the forward momentum of the plane obviously is critical to flight; so i'd say yes, theoretically if the engines could pull enough air without the added benefit of air flowing over the wings by forward momentum, it could take off, but i doubt that any real plane could pull that much air over the wings, and the air would mostly just be going through the engines rather than over the wings anyway, so it would take such monumental power as to be practically impossible i would think, the engines basically have to create a wind tunnel for the plane to lift off in; so be it
rollers, conveyor belt, frictionless surface, all the same
you'd be better off putting a ginormous fan in front of the plane
just pulling air THROUGH THE ENGINES, does NOTHING, the engines must pull enough air OVER THE WINGS themselves, yes? no? whaeva; to many math monkeys about
