@RobertGary1 Playing Deviil's advocate....what about a fighter aircraft, such as an F-15 or an F-16, with a better than one to one thurst ratio? I'd said the thrust is generating lift there.
-
@Whiteeboyz I see how it might appear this way, but thrust is a force which pulls or pushes a plane directly. Gliders have no such force acting on them; they are merely using gravity to build up speed so that lift is generated from the wings. Once enough speed is attained, lift will be generated even if the glider is climbing. Speed is needed to generate lift, gliders use gravity to get speed, powered aircraft use thrust. Different force, same result!
-
lift is produced by the wings, thrust is needed for speed and to get the plane in a state where the wind under wings is moving at a different speed then the air on top. i forget if its faster or slower.
-
@RobertGary1 Don't you need thrust to gain any altitude though? Gliders produce forward motion from gravity, they're in essence "gliding" not "flying", This forward motion (due from gravity) is the gliders "thrust". This in turn produces this "lift" sufficient enough for the glider to "glide". You need thrust to to fly/glide, be it from gravity or the spinning fan on the front of the plane.

LoL Must be another Prop Low Oil Light coming on again. I would know I worked on that damn plane. Thank god it went to the bone yard.
-
@alexjamaalstraughn True, but hot spots aren't everywhere though, without them you need altitude to maintain speed to stay in the air, otherwise the glider will stall and you'll crash.
-
@coryboy345 not necessarily, gliders use hot spots in the air to gain the altitude. Hot air as we all know rises and when the glider pilot finds a hot spot he circles around in that hot spot til he is as high as he wants to be.
-
@RobertGary1 but without thrust, you need altitude to generate lift.

I was once on a c-130 that had an engine fail, didn't even know about it until after we landed.
How much thrust does a glider have? They don't seem to have any problem generating lift. Lift is not geneate by thrust.

Not at all. Lift is not produced by thrust.
