Why does airspeed change when I adjust the prop?
Mxsmanic,
OK, but why does the airspeed drop?
Because your power output is lower.
It seems that high speed and fine pitch should produce exactly the
same thrust as low speed and coarse pitch, as long as the prop blades
don't stall or reach transonic speeds.
Why?
So you're saying that lowering the RPM necessarily means a drop in net
thrust unless the manifold pressure is increased (a throttle
increase)?
Yes.
