Then press number 2 so the R bar increases with the rotor speed.

To counter this, the rotor speed is not allowed to increase above a certain value.

The rotor speed can either be increased or decreased by an appropriately designed controller.

Most commercial instruments are extremely versatile, with an extensive choice of rotor speeds and a temperature control system.

This type of aerodynamic noise is mostly low frequency determined by the rotor speed.

This means that as wind speed increases, rotor speed should increase proportionally.

The rotor speed required for flight is approximately 18 rpm.

Pitt reduced the collective pitch to keep the rotor speed from falling too quickly.

The higher the loading, the more power needed to maintain rotor speed.

Here, the relative wind will not decrease in fact it increases with rotor speed.
