 |
|
I bought a digital level that is accurate to .05 degrees. Here are the results of a few planes. All measurements in degrees down; i.e., down thrust angle.
Tiger 86M: .7 degrees
Tiger 6FT: .3 degrees
Tiger 747: .3 degrees
Tiger 57V: .15 degrees
Traveler 89L: .4 degrees
Traveler 62U: .35 degrees
RV4: 0 degrees.
Note: ALL aircraft appeared to have the cowling aligned with the spinner.

Relative to what? Top of engine case to canopy rails? You level reads out to the closest 0.05 degree increment? i.e. 0.1, 0.15, 0.2 degrees?

OK, I'll try to clarify.
When I say, "All measurements in degrees down; i.e., down thrust angle." I mean the down thrust angle from 0 degrees. (if you wish, Google 'down thrust angle' for a more complete description including pictures on some web sites.)
For example: if Tiger 86M were all leveled out and a level was placed on the engine, it would read 0.7 degrees down. Hence, the statement, "All measurements in degrees down; i.e., down thrust angle."
I hope that helps.
Yes, when I said the accuracy was .05 degrees, that means .00, .05, .10, .15, .20, .25, . . . . . .95, 1.00 (where 1.00 means 1 degree)

I understand all of that, but you still didn't answer my question: where specifically on the engine did you locate the level? Crankshaft flange? Top of engine case?

If you do a google search of finding the thrust angle of the engine, you'll find a page that says to use the top of the rocker boxes. They are level with the crank. Canopy rails are zero on the Grumman.

Sorry, I remember now that you mentioned that you used the top of the rocker boxes before.
