Calculate the Speed of a Helicopter Rotor Blade Tip

What is the speed of a helicopter rotor blade tip rotating at 510 rev/min with blades of 3.30 m length? The speed of the blade tip of a helicopter rotor can be calculated using the formula: speed = radius * angular velocity. In this case, the angular velocity of the rotor blade is 53.41 rad/s and the length of each blade is 3.30 m. By multiplying these two values, we can find the speed of the blade tip.

Calculation of Helicopter Rotor Blade Tip Speed

Given data:

Angular velocity of rotor blade = 53.41 rad/s

Length of each blade = 3.30 m

Calculation:

Speed of the blade tip = radius * angular velocity

Speed of the blade tip = 53.41 * 3.30 = 176.24 m/s

Final answer:

The speed of the blade tip is approximately 176.40 m/s.

Explanation:

To find the speed of the blade tip, we first converted the rotational speed from rev/min to rad/s. Then, we multiplied the angular velocity by the length of each blade to calculate the speed of the blade tip.
