If it’s because of wind tunnels that helps push the planes faster, how much slower would they be if they weren’t in those wind tunnels?
If the average flight from NY to London is 7H and 10M what would the flight time be?
In: Physics
I think you mean jet streams. Wind tunnels are giant ducts with fans, used to test aircraft.
And no, while the jet streams sometimes help, they’re not the reason for flying so high. The reason is that air resistance is a massive drag (literally), so if you can get above most of the air, it saves a lot of fuel – more than what’s needed to get up there. Jet engines can handle this, because they have compressors that can easily squeeze that sparse air into something that supports combustion.
