Yeah, maybe ur right. At 175mph is doesn't matter what is happening to the engines...the 175mph is what the engines are giving out regardless if something is pushing it, pulling it whatever.

No, the turbines do not move the air across the wings. Generally they're mounted UNDER the wings, and the outlet is BEHIND the wings. Some are even mounted in the back. Or how about a small plane with a single prop in front... how is that gonna move any are across the wings?? It's not even close I don't know where you got this wacky idea that the engines are like a fan blowing air across the wings. THEY'RE NOT!! They have one purpose and one purpose only.... to move the plane forward. That is IT! Once the plane is moving forward, the surrounding air moving across the wings produces the lift But since you want to argue.... by your logic, explain to me how this plane ever made it off the ground. Where's the turbines drawing the air across the wings?? Hmmmmm.... ![]() Seriously bro.... not trying to sound like a dick here or anything, but you might want to educate yourself a little bit on the subject matter before getting into an argument.... just sayin ![]()

![]() If you strapped the plane down from the top and put it on a scale, spun up the turbines at full pop, would the plane weigh any less? If so, then there is some lift acting on the wings. Speaking of commerical jets with the turbines under the wings.

Agree...the wheels would just spin at the ground speed plus the conveyor speed. Never argued against it. They can be neglected.

An Airplane does not need "propulsion to fly.
It needs airflow over the wing surfaces. If you want aircraft to fly, you do not need ground speed...you need airspeed. Simple way to show this is to stick a paper airplane in front of a fan. Propulsion's purpose is to maintain airspeed (to over come aerodynamic drag) necessary to ensure lift. In the case of a glider, gravity is used to achieve proper airspeed (once disconnected from the tow aircraft and aerodynamics take over. A helicopter use the same principle with rotor hub altering the angle of attack during each rotation as the rotors experience vary airspeed. You can get into more detail of aerodynamic (vortex crap, drag) The key to creating lift is the negative pressure on top of the wing with some positive pressure under neath Official NASA yapping Quote:
