Hello how is everyone in the group? This is a dome idea, I'm not sure if

it

works, but here I go! I'm putting a turbo charge 13b setup on my

aerocanard,

my question is, can we use a cruise propeller designed for 180 to 200 hp
making over 200 MPH and over boost the engine with the turbocharger on

take

off and make it a clime propeller with the engine producing about 250 to

270

hp? sine we can dial the power on the turbocharger engine I thought that
this may work. I'm about to order my propeller and I was looking for

some

comments on this issue. any comments will be gladly appreciated.
thanks :)

The basic approach has merit, but is not likely to provide quite as much
gain
as you envision. Wth a fixed pitch prop the take off is limited by the fact
that the prop load is not letting your engine make full horsepower.
Typically a 200hp engine (at speed) is bogged down to about 2/3 at
static, to  about 120 hp. Now, if you can boost manifold pressure about
50 percent, the torque and hp at that rpm will also go up about 50%
to about 180, this will increase rpm (about cube root law)about
14%, also bring hp up another roughly 14% to a bit over 200hp
worth of take off power, Of course this is all predicated on your
ability to really increase the boost that much, and you can handle
the heat and stress loads. - Vance J
