Hi Guys
A successful 32 minute Flight #3. I was very pleased.
Main change this flight was winding in some prop pitch and extending the envelope to 140 KIAS.
Configuration of flight was: OAT was a low 62F Coolant Inlet - 21in2 Oil Inlet - 8in2 Total Outlet - 80in2 Coolant peeked at 226F Oil peeked at 218F EGT peeked at 1724F Fuel Flow peeked at 18.7 GPH (Flowscan - not sure how accurate from the provided data) We are still keeping immediately above the airfield
Reflections: Idle RPM to low Temps are to high on climb out but maybe OK when we get her up to her cruise of 190 KIAS I will investigate water spray cooling for the initial climb. Does anyone have experience/data?
Here is a graph of the data.
Cheers
