Question

To: Dave Jackson

>"Some individuals will look at this as a pure aerodynamic function...... I will totally believe that theory if someone can convince me "<

This is what I said:

Some individuals will look at this as a pure aerodynamic function, which causes the blades to fly to the commanded position, and gyroscopic precession be damned. I will totally believe that theory if someone can convince me that there is a law or rule or theory in aerodynamics that explains why this phenomenon takes place in 90-degrees as opposed to 35-degrees or 125-degrees.


>"It is very easy to prove aerodynamic precession"<

This is what I said:

It is very easy to prove aerodynamic precession by using a Bell analogy indicating that in 180-degrees of rotation the rotor has aligned itself with the swash plate. Now, try to justify that theory by addressing a multi blade rotor system where the rotor never aligns itself with the swashplate.

No more evasion. Please address my comments in detail.
