So in theory a plane can fly because the shape of the wing causes the air above it to have a lower pressure than the air below it making the plane fly. However paper planes and those cheap kids planes don’t have any curve to cause this. Both can still glide pretty well.
Is there something that makes these craft special that doesn’t apply to big jets? In the same vain how do fighter jets or stunt planes keep themselves in the air when they fly upside down?
In: Engineering
Basically they use the propulsion of you throwing it as energy to maintain lift, but of course after a while, the paper airplane falls due to nothing pushing it against the air to cause lift. Jets or really any planes on the other hand have engines that maintain that propulsion so they don’t depend the force of you throwing it to create lift, these planes in contrast to paper planes only depend on the engine or propeller running to maintain lift therefore planes being able to run for huge amounts of time.
