Does anyone have a ball park figure for thrust on a 200 horse lyco w/ a 3 blade prop set for cruise? Dust I know your going w/ a 200 horse set up. I know thats alot of specy info w/ alot of variables to include but it does not need to be exact. Is 300 LB of thrust a close figure or will it be alot higher than that? Just curious.

200hp max @75%power=150hp*0.8(prop efficiency) = 120 Thrust HP at the prop.

THP=Thrust * TAS(ft/sec)/550

180 mph= 264 ft/sec

120=(x * 264)/550

120=0.48x

Thrust x = 250 lb's

 

:D
