An idea that popped into my mind...
ywo subject question lines...
1. Can a plane on a treadmill take off?
2. Can a plane take off from a treadmill?
In the first instance, the airplane is attached to the
treadmill and would have to lift the weight and shape of the
treadmill. In the second, the airplane would behave
differntly depending on whether the treadmill was powered or
just a belt on rollers.
a. If just a belt on rollers, the engine thrust would drive
the airplane forward until it was not on the treadmill
anymore, thus it would have air movement over the wings and
would take-off. If the brakes were not locked, either or
both the tires and treadmill would "roll." If the brtakes
were set, the treadmill would roll and the airplane would
likely come to a stop when it departed the treadmill unless
it was alrady at flying speed.
b. If the treadmill was powered [and everything was timed
in sync] the belt would be accelerating rearward and the
engine thrust would be pulling forward at the same rate,
thus the airframe mounted wigs would have near zero airspeed
and lift and would not fly.
b1. If the treadmill was powered and ran forward, it would
act as a catapult and launch the airplane or at least
assist.
Hey, let's build a really big treadmill and try several
different airplane types, such as a Helio, a Maule, a Cessna
Caravan, and a C5 [a really big treadmill] and see what
happens.
