No, for LTE, the Bell Spin Doctors concocted it to cover up the poor design of the original Kiowa small tail rotor, to avoid the wrath of the Army, after losing a few machines. The LTE story...

Tough bickies, Robbiee, it's part of the problem where the instructor barely has 100 hours more experience than the student, "fake news" gets passed from one junior to the next, and like Forrest...

As long as you theorists are happy, us actual pilots can continue in our own direction, which may (or may not) be 90 degrees to where you are pointed.

The missing element is Rigidity in Space. Because of all the twisting, flapping, dragging and aerodynamic blade forces, the "disk" is dynamically unstable - and gyroscopes are not. It will not hold...

Oh boy, this is getting tedious. It is called lift.

You admit that the R22 does not behave in the manner a gyroscope is obliged to perform. It has forces acting upon it. So it is only LIKE a...

The force isn't an instant thing. It starts from zero, builds to a max upwards, then transitions to a max downwards, and back again - a force of some kind is always there, up and down.

Never said "instantly". But you keep bringing it into the conversation.

F=ma. For a given force, the acceleration will depend on the mass. An empty bucket will get to shoulder level in fewer...

You're arguing in circles mate. It takes time to move? Of course it takes time. Start with zero displacement, and apply a force. The item accelerates while the force is present, and displacement...

F=mA.

Apply some pitch from the cyclic via the swash plate. The increased AoA produces lift, a Force. This lift acts on the mass of the blade, and accelerates it upwards. But that acceleration...
