kaplan propellor looking for

[french44]

Hi ,

I'm looking for open water test of KA4 series with and without kort. We have some trouble to have all the rpm on the engine and the calculation was carried out with b series so i want to check the difference beetween the 2 open water diagram .

Thanks a lot

Vol 2, Chpt 6, Sect 9 of the current edition of PNA has the coefficients for a Ka 4-70 in a 19A and 37 nozzle. Without a nozzel, a Ka is going to absorb much more torque than a similiar B series for the same thrust-rpm.

Thanks, i know that the torque should be more than b serie but i need to prove to the guys this fact and for that i need chart for this propellor : D 0.9 m ; Step : 0.846 m; p/d= 0.94 and Ae/A0= 0.6 kaplan KA4-60 . i have the chart and even software for b serie. I'm in central africa river congo and it's not easy to have doc or post mail ( 3/4 week mini) so if someone have it it will be very sympathic to send me.

Thanks a lot in advance
