Jet engine turbine disk

Analyzing Jet Engine Turbine Disk A jet engine turbine disk is one of those aero engines parts which are vital for the working of the airplane. This will be a circular disk which is created from materials of very high tensile strength such as titanium or some kind of special nickel. That disc is attached to a rotating spindle that spins very quickly — sometimes up to 15,000 times every single minute. That's an alarmingly high velocity

A disk is hollow and that there is nothing inside it. These O.B.T jet engine compressor blade material are actually blades sticking out on the outer edge of the disk. This air is forced against the blades when it comes into the engine, which in return start spinning really quickly. The spinning motion generates tons of power — enough that it runs other things on the plane, like the generator (which makes electricity) or even a hydraulic system that helps raise and lower the wings.

Materials science and engineering behind the innovation of turbine disks

The turbine disk in a jet engine spins very fast, and because it is so hot. Spinning blades can generate quite a pocket of heat due to the friction with air. In order to prevent the disk from overheating and becoming damaged, it has specialized cooling holes built in. These holes allow the air to circulate inside the disk providing a means for cold air to enter and hot air from within to escape, allowing the disc not overheat

How the blades are connected to the disk is also crucial. But they aren't simply glued or screwed in place as you might expect, instead they are fit together using a unique method know as dovetailing. That is to say, little slots are created on disk and blades too which can sit close with each other similar to 2 elements of puzzle. The whole setup is a very strong bond, which will be able to resist the high speed and temperature produced as the disk runs with the engine running.
