The single rotor engine is finally running again.
Dynamically balanced and a new ignition system helped a lot.
The prop is set to give around 6000RPM at WOT. The
repeated result are:
RPM
6000/min
Fuel flow 6.8
gph
MAP
27"
Mixture 14.6
EGT
1700 F
Oil and water temperatures were stable at 160/140
respectivly.
The fuel flow would indicate 80hp at a BFSC of .5 .
If this is anywhere close to what the engine produces, the predicted 110hp at
7500RPM are feasible. Keep in mind that this is a 12A based engine. For a 13B
based version it will be close to 150hp.
I now will have to put all my efforts into putting
the flyable engine together.
