While an aeroplane is taking left turn as shown in figure and the propeller is rotating in clockwise direction gyroscopic effect on aeroplane seen from back side of the plane.

As the propeller is rotating in ox axis, the axis ox is called as axis of spin. The plane is taking right turn that means axis ox is rotating towards the axis oz. In an experiment, a top spinning in one direction and tilted as it spins will exhibit precession in a given direction.

If the top is spinning in the other direction, precession will be the opposite that it was with the first top. The Wikipedia article on precession has a picture of a gyroscope that has a bit of animation to hopefully make it clearer.

What is a gyroscope? A gyroscope is a device for measuring or maintaining orientation, based on the principles of angular momentum. Although this orientation does not remain fixed, it changes in response to an external torque much less and in gyroscopic effect on aeroplane different direction than it would without the large angular momentum associated with the disk's high rate of spin and moment of inertia.

The device's orientation remains nearly fixed, regardless of the mounting platform's motion, because mounting the device in a gimbal minimizes external torque.

How do a gyroscope work?

What is Gyroscopic effect on aeroplane

The fundamental idea behind the working of a gyroscope is that of conservation of angular gyroscopic effect on aeroplane. But to understand this idea more fully, it may help to explain a few things, so let's dive in by talking about a wheel and axle and how its mounted. If a wheel or disc spins about a center on a axle, that spinning wheel carries with it some kinetic energy.


The wheel has mass, it took energy to set it spinning, and it is now spinning, hence the energy of its spin momentum. If we then mount the axle in a ring, we can hold the ring gyroscopic effect on aeroplane the wheel will spin on the axle.

What are the parts of an aeroplane?

Now we'll mount the ring with the spinning wheel in it. When we look at the ring with the spinning wheel in it, we gyroscopic effect on aeroplane find two points on our ring that are in the plane of rotation of the wheel.

Gyroscopic effect on aeroplane then put two small "stubs" out from there and mount our first ring in another ring. The mount will allow us to hold the outer ring and allow the inner ring to move independently.

Lastly, we take a third ring and mount the whole thing inside that one.

But we need to be sure to pick two points on the plane of rotation of the wheel, but 90 degrees from the points where the innermost ring mounts to the gyroscopic effect on aeroplane ring. We have set up gimbals so the outer most ring can be mounted to an object and the inner rings will allow the gyroscopic effect on aeroplane of the spinning wheel to always point in the same direction.

The use of very low friction components in our mountings and the application of electromagnetic pulses to keep the gyroscope spinning will insure things keep working.

So handling of the aeroplane becomes bit difficult. To understand the phenomenon of precession refer the diagram below.
