Thrust Measurement
 

I've been stumped when using the Thrust HP program. It calculates different thrust for more or less blades, but the pitch doesnt change the thrust at all. if RPM is constant (i know, in the real world it will decrease from x if you increase the pitch) shouldn't an increase in pitch increase thrust?

does anyone know of other thrust/hp calculators??


thanks

Thrust Measurement
 

Real world numbers are best taken with a scale on the tail wheel of the plane...The thrust chart shows 25 lbs for an 18-6 Mejzlik at 9000 rpm..Spring scale shows 17.5....Another test showed 18+ on a plane with a Zinger 18-6 at 7800.....There are too many variables to get accurate numbers from a chart...
