What is Gyroscopic effect on aeroplane?

Answer 1

Gyroscope (mechanism) is used to determine the effect of a turn taken by an aeroplane. In a short let me describe them,

1. If the rotation of a propeller/ rotor is in CLOCKWISE when viewed from REAR/ BACK SIDE and the aeroplane takes a LEFT TURN, then reactive gyroscopic couple (which is equal in magnitude and opposite in direction of active gyroscopic couple) will tend to RAISE THE NOSE and DIP THE TAIL.

2. If the above similar conditions are considered when the plane is taking a RIGHT TURN, then the reactive gyroscopic couple will tend to RAISE THE TAIL & DIP THE NOSE.

3. If the rotation of a propeller is in ANTI-CLOCKWISE DIRECTION when viewed from REAR of the aeroplane and the plane takes a LEFT TURN, the reactive gyroscopic couple tend to RAISE THE TAIL & DIP THE NOSE.

4. If we consider the similar conditions of (3), and a plane takes a RIGHT TURN, then the reactive gyroscopic couple tends to RAISE THE NOSE & DIP THE TAIL.

To remember it easily, you can use RIGHT HAND SCREW RULE.
