Brief Description: Some Flight Data
|
|
Continuing my Phase 1 flight testing. The Engine has stablized in temps and oil burn.
Compression checks are solid at 78/80. Oil analysis came back normal.
I decided to take her up to altitude, and check climb rates fuel flows and cruise performance.
After takeoff I established a best rate of climb, which I calculated to be around 94 knots in my plane from pervious flights. Dialed 94knots into the auto-pilot and a way we went.
Outside air temps at sea level was 83F, at 10500ft 49F. Density Alt 12300ft.
The airplane settled in at 1600fpm climb through 5000ft, 1250fpm through 8000ft, and 850fpm to 10500ft. I had to increase the climb airspeed to 120kts to keep the CHT below 400F at 8000ft.
Time to climb to 10500ft 9min 40sec. not including the ground roll. I was happy.
So basically averaged 1000fpm from sea level to 10500ft.
Sea Level HP measured at 188HP via the onboard computer.
Maximum cruise at full power 125HP, 67% power, TAS 167kts, 9.0gph. Peak
Best Economy 99HP, 55% power, TAS 154kts, 7.5gph. 25F ROP.
Since it is carburated, leaning is a best guess, but temps were stable and close, engine ran smooth.
Computer indicated 19.0 nautical miles per gallon, which equates to 22 statute miles per gallon.
not bad for a 360 cubic inch engine. about the same as my car.
Lycoming 0-360A1A
Dual P-Mags 114s Electronic ignition
Whirlwind GA200L set at 21.5 degrees
I still have some fairings to fit and install around the main gear legs.
maybe I can get a little more out of her.
