Check the rotor disk to see that it spins true.

In early models, the alphabet ring was fixed to the rotor disk.

Dynamic visual representation of rotor disk tip path plane 20.

Smooth rotor disks were originally proposed, but these gave poor starting torque.

Keys were easily changed by changing the rotor disks and the plugboard wires.

A later improvement was the ability to adjust the alphabet ring relative to the rotor disk.

One of the key difficulties lies in modelling the induced velocity on the rotor disk.

In 2010, it warned that the low-pressure turbine rotor disks could fail.

This had the advantage that each rotor disk could at least share the flux of two expensive magnets.

Reinforce the rotor disk with hot glue.

As this was still an inadequate power, extra rotor disks were stacked axially, along the axle.

Conservation of energy considers these parameters as well as the induced velocity at the rotor disk.

This works, in essence, by forcing water which would not have flowed through the turbine through the rotor disk.

The part investigators suspect failed, the engine's rotor disk, is still missing, having apparently fallen somewhere onto Iowa farmland.

He looked like a doll tossed from a speeding car onto a busy freeway when he hit the rotor disk.

Fan blades broke off the rotor disk and the cowling around the engine didn't contain the fragments.

Be smooth on the controls, sudden, jerky movements will sap precious energy from the rotor disk.

Recheck the rotor disk by spinning it.

Carefully push the pointed end of the turbine shaft through the top of the rotor disk at its exact center.

For helis: The rotor disk is the effective wing, and airfoil refers to the shape of the blades.

Helicopters do not experience this problem as increasing the size of the rotor disk does not significantly impact the ability to control blade pitch.

Check the position of the rotor disk on the dowel by placing it inside the frame and re-inserting the push pin.

It is also questionable whether the rotor disks, because of light construction and high stress, would have lasted any length of time if operating continuously.

As there is now only a single rotor disk, the horseshoe magnets used are stacked together in groups, but act through a single pole piece.

New aggressive super stiff tail blades are included as standard equipment for the 9 3/4 inch tail rotor disk.
