Thrust HP or???
 

Hi,

Does anyone know of a program for determining thrust other than Thrust HP? Hopefully one a little more accurate??

I had another program before my computer crashed, but I didn't get to use it before my computer crashed, and now I can't find it again on the net.

Any help will be appreciated.

Thanks and Happy Holidays,

Hi...

Try to find a program called "AeroDesign Propeller Selector"... That´s what I use, and it seems to be fairly accurate.
As far as I remember it was only off by a few pounds when I measured my G-62.

Do you have a link to this program?

Nope... can´t remember where I found it... But try a Google search... Maybe it will show up......

Hey...I found it.. Here you go.

Take care,

THis program looks good!
I will do some checks against thrust HP and see what happens.

Hi
That propcalc seems to be more realistic than the very optimist TrustHP!![8D]

I have a small gasser MVVS1.6 turning an APC 17x10 at 7400RPM.
From ThrustHP: 13.72 lbs thrust
Propcalc:13.15 lbs thrust (with 10mph airspeed)

MA 18x8 at 7000RPM.
From ThrustHP: 14.5 lbs thrust
Propcalc:12.17 lbs thrust (with 10mph airspeed)

What's the relation between the airspeed and thrust? Is there someone who knows what does 'airspeed' mean in the first case?
