Another propeller for the garage

[APDrone]

Think about it the other way around: For example the propeller of a T6 Texan can pull a 5,000 lbs weight through the air at a speed of 150-200 mph spinning 2250 rpm. Now I'm not at all positive this calculation being accurate, but it gives some directions to thought: 2250 rpm is 25 times 90. 5000 lbs/25 is 200 lbs. If you could build a 200 lbs plane the size of a Texan, would it fly 150 mph @ 90 rpm? Notice that the weight should be balanced all over the plane, which means this is purely hypothetical.

Gads, I hate it when a question/comment bugs me to try to apply some sort of math to it..

If he's running 90RPM in the garage, I seriously doubt it's punching air out at 150+MPH. .. of course, if it did/could, that would be a spiffy cleaning-out option..

FYI.. the T6 Texan engine ( R1820 ) weighs 1200lbs, by itself.

The T-6 had the Pratt and Whitney R-1340 not the Wright 1820.

At 90RPM that prop would move little air compared to what it did on the aircraft.  That engine idles at around 800 RPM and won't move the airplane at that RPM.

Guilty!!  I was going by the A-27 which listed as a variant of the AT-6 Texan(BC1). It used the R1820. 

The 1340 is only 930 lbs..

Thanks guys! From what I can find, the prop is not a 12D40 from an AT-6.  But is instead a Hamilton Standard 2B20. While it did have some military applications such as on the UC-78, traces of red paint on the tips (as well as yellow) lead me to believe this came from a 1940s Cessna or Waco.
So instead of painting the stand OD Green, I may just stain it dark brown.  But, I am still thinking of stenciling, “Hamilton Standard Mod. 2B20” on the piece that supports the center cylinder.

The prop is done.



Here is a pic of the worst damage:

And painted:



I’m pretty happy with how it turned out!

CHEERS!
