How gyroscopic couple work in a aroplanes and ship?

Answer 1

Effect of the Gyroscopic Couple on an ship and Aeroplane :-

Ships and aeroplanes consist of large moment of inertia propeller and fly wheels. When aeroplane or ship takes right or left turn there occurs a rate of change of angular momentum because of change of direction of angular momentum vector. Thus a counter couple is produced when they terns.

1. When the engine or propeller of aeroplane or fly wheel of ship rotate such that the spin angular momentum vector is along the sailing direction and when the aeroplane or ship takes a left turn, then the effect of reactive gyroscopic couple will be to dip the nose (stem: for ship) and raise the tail of the aeroplane or ship.
2. When the aeroplane or ship takes a right turn under similar conditions above, the effect of reactive gyroscopic couple will be to raise the nose and dip the tail of the aeroplane or ship.

In the case of ships the fly wheel must be mounded such that the spin axis is along the length so as to maintain dynamic stability.

Answer 2

Gyroscopic couple in airplanes and ships is based on gyroscopes generating a force when they are rotated. In airplanes, gyroscopic couple can affect the stability and control of the aircraft when there is a change in orientation. In ships, gyroscopic couple from rotating components like propellers can cause the ship to yaw or roll, affecting its stability and maneuverability. Gyroscopic effects need to be accounted for in the design and operation of both airplanes and ships.
