What is the tangential speed of a helicopter blade tip?
Parameters for Calculating Tangential Speed
The tangential speed of a helicopter blade tip can be calculated using the formula v = r × ω, where v is the tangential speed, r is the length of the rotor blade, and ω is the angular speed.
Given that each rotor blade is 3 meters long (radius) and is rotating at an angular speed of 63 rad/sec, we can find the tangential speed using the formula.
Calculation of Tangential Speed
To calculate the tangential speed of the helicopter blade tip, we use the formula v = r × ω, where r = 3 m (blade length) and ω = 63 rad/sec (angular speed).
Substitute the values into the formula: v = 3 m × 63 rad/sec = 189 m/s.
Therefore, the tangential speed of the helicopter blade tip is 189 m/s.
