109 prop pitch (rpm) and the supercharger

[Crumpp]

I am simply pionting out that what you said about how to fly a Bf109 is in conflict with what Steinhilper said about how to fly a Bf109

But is not in conflict and agrees with what is related in the anecdotes.

If you understood how an adjustable pitch propeller works in conjunction with the engine, you would see that.

It is useless to discuss it with you. Have a nice life, Tagert.

To produce maximum thrust at full power your tip speed should fall between .88 and .92 mach. To move between .88 and .92 mach usually takes a change of about 110 to 120 RPM. This of course varies depending on your particular propeller and the temperature.

If your tip speed is less than .88 mach you should increase RPM to achieve maximum thrust. If your tip speed is greater than .92 mach you should reduce RPM to achieve maximum thrust. Do not exceed the published operating limitations of your engine or propeller.

Over .92 mach the airflow begins to detach from the propeller which decreases efficiency and dramatically increases noise. To improve performance and public relations you should consider reducing RPM so as to fall within the .88 to .92 mach range. Your propeller will be producing maximum thrust which is good for you, and less noise which is good for all of us.

If that is true..

Why get so upset and say I was attacking you?

Brings to mind the old saying..
