# Does the “Torque-Induced Precession” of the two rotor blades cause the V-22 Osprey to tear itself apart

Concerning Bell Boeing V-22 Osprey Aircraft:

Does the “Torque-Induced Precession” of the two rotor -- 3-blade, propellers cause the V-22 Osprey to become unstable.

In the case of a helicopter the Earths gravity pulls on the aircraft hull up to the rotor assembly, rotor blade “dissymmetry of lift.”

Does the changing of the two gyroscopes, tiltrotor, cause “harmonic coupling” and or “mechanical resonance” - causing the aircraft to become unstable?

• For this question, how does a tiltrotor differ from a non-tiltrotor two-rotor helicopter such as a Chinook? How does it differ from a conventional twin-prop airplane? (If it's about while the rotors are tilting, how does that differ from a Chinook or a twin changing pitch as a whole?) Dec 20, 2023 at 20:36
• "Does the “Torque-Induced Precession” of the two rotor blades cause the V-22 Osprey to tear itself apart?" Yes it does, all of the V-22 were destroyed because of that reason 😉 Dec 20, 2023 at 21:54
• Please note, “The second property is precession. Let’s follow the definition carefully. It is important to understand the effect of precession when we consider gyros. If an external force is applied to change the direction of the rotor spin axis -the gyro resists the change and instead moves the force at right angles to the direction originally applied, this is precession. The rule of precession states that the gyro will precess at 90 degrees to the applies force. youtube.com/watch?v=JtniROSrovs Dec 20, 2023 at 23:36

• How does a tiltrotor differ from a non-tiltrotor two-rotor helicopter such as a Chinook? How does it differ from a conventional twin-prop airplane? The answer is the aircraft: angular momentum, structure and especially helicopters - stable center of gravity. Notice that the V-22 Osprey has two heavy engines relative to center of gravity.
