If a plane tried to take off on a runway, which was also a treadmill running in the opposite direction to the plane’s travel, would the plane be able to take off?” (the answer is yes BTW)

I have just stumbled upon this and i want to discuss it but it was posted ages ago in a different thread

I think the answer is yes.

Cricket!

Yes

That’s what I said as well.

yeah. the plane doesn’t turn its wheels to take off does it? it uses the engines

Great minds think alike

I think you’d struggle to find a treadmill on the market which would do much upwards of 20mph, so the plane would easily outrun it. Also, they tend to be quite small for fitting in gyms, garages, etc, so doubt you’d get one big enough for a plane.

maybe see if BoB will crowd fund a giant treadmill and we can find out

planes don’t need treadmills mate

it was me that posted that

if the treadmill is going at say 20mph the wheels would just turn 20 MPH faster - and the plane would move forward at the same speed it always does. The forward motion comes from the jets, not the wheels

Rolling Road instead, innit.

What if the treadmill was running the same way as the plane. Could it take off twice as fast? That might ease some airport congestion.

to fly not to move

I mean, airports already do this for humans. Seems like the logical next step.

Then after runways, normal roads, pavements etc could follow. Let’s get people where they’re going much faster.

if the treadmill was somehow able to exactly match the planes forward speed then I think you are right

but if we assume the treadmill moves at a constant speed then the wheels will just turn faster and the plane will move along the treadmill/ runway at its normal speed, and take off using the airflow as normal

I’m basing my answer on the Eunice Huthart theory of treadmills.

If she can beat the travelator, then I would back a plane to lift-off from one. Easy-peasy, smelly cheesy.

speed of the treadmill doesn’t make a difference
