Aeroplane on a treadmill...?

This is where our community discusses almost anything! While we're mainly a Cambodia expat discussion forum and talk about expat life here, we debate about almost everything. Even if you're a tourist passing through Southeast Asia and want to connect with expatriates living and working in Cambodia, this is the first section of our site that you should check out. Our members start their own discussions or post links to other blogs and/or news articles they find interesting and want to chat about. So join in the fun and start new topics, or feel free to comment on anything our community members have already started! We also have some Khmer members here as well, but English is the main language used on CEO.

Aeroplane on a treadmill...?

Post by OrangeDragon »

Without looking it up and cheating... what do you think would happen it a 747 on a giant treadmill that would go backwards as fast as the plane would move forwards were to try and take off?

And why?

No forward motion = no lift = absolutely nothing would happen!

What if it was an F-22 instead of a 747?

Yes, airflow provides all the lift. If the thrust was canceled as you say it would just sit there and roar

I took off into a strong Santa Ana one time. No forward progress.
Just revved the Continental, pulled the flaps, and up and making
forward progress.

It would take off if both forces were the same.

Thrust is not provided by wheels, but by the jets/props, so the plane would move forward off the treadmill, and then take off.

The wing turns thrust into lift. So if you move enough air
under the wing, you get lift off. Even if you are stopped on the runway.

Before I give a answer, I want to know is there a Cambodian pilot flying the 747 ?
Cambodia,,,, Don't fall in love with her.
Like the spoilt child she is, she will not be happy till she destroys herself from within and breaks your heart.
