rotor speed in a sentence

Examples

1. A Dahlander motor achieves different speeds by switching the configuration of the electrical windings, indirectly adding or removing poles and thus varying the rotor speed.
2. From this figure, we can see that both the angle \ theta and the apparent wind speed W are functions of the rotor speed, \ omega.
3. where \ omega is the rotor speed ( in radians per second ), R is the length of a blade, and v is the wind speed.
4. This means that as the wind speed changes, the rotor speed must change to such that C _ p = C _ { p ~ max }.
5. Due to the difficulty of balancing the craft, a rotor speed of only 47 rpm was achieved instead of the 60 rpm which had been calculated as necessary for takeoff.
6. So it can be established that if the angle of attack needs to be increased to limit the power production of the wind turbine, the rotor speed must be reduced.
7. The system developed relieved the helicopter pilot of the need to control rotor speed directly and in this way was the analogue forerunner of all subsequent FADEC systems world wide.
8. In reference to the above torque-rotor speed diagram, by reducing the rotor speed at high wind speeds, the turbine enters the stall region, thus bringing some limiting to the power output.
9. In reference to the above torque-rotor speed diagram, by reducing the rotor speed at high wind speeds, the turbine enters the stall region, thus bringing some limiting to the power output.
10. The Sycamore had a relatively high rotor speed for the era, which was claimed to deliver increased smoothness during flight and provide for a safety advantage in the event of engine failure.
