Yes, you’ve got this mostly down. The dyno comparison is simply incorrect. The car is imparting its force upon the dyno, the airplane is not. The airplane is imparting its force upon the air.Until the wheels lift off the ground
the plane and the wheels are rolling on the ground
being pushed forward by air pushing against other air
by a prop or a jet ,,pushing air back against other air...
When on the ground the prop/jet propels you forward on your wheels
When you have reached, say 65 mph in a Cessna 150
The wings have enough wind flowing over them to create lift
and the pilot pulls back on the wheel
On a treadmill going clockwise and the free spinning wheels going counterclockwise
exactly matched ... I don't see that plane going forward to get up enough airspeed to create lift on the wings
Anyone here ever dynoed there car???
For every action there is an equal and opposite reaction in terms of a jet, which is the easiest to explain.
