Calculate the Total Moment of Inertia of Helicopter Blades

What is the formula to calculate the total moment of inertia of helicopter blades? The total moment of inertia of the helicopter blades can be calculated using the formula: I = 2/5 * m * r^2 where I is the moment of inertia, m is the mass of one blade, and r is the distance from the center of rotation to the blade.

Formula for Moment of Inertia Calculation:

The moment of inertia of an object is a measure of its resistance to changes in rotation. In the case of helicopter blades, the total moment of inertia depends on the mass of each blade and its distance from the center of rotation.

The formula I = 2/5 * m * r^2 represents the moment of inertia of a single blade. To find the total moment of inertia of all blades, we need to multiply this result by the number of blades.

Calculation Steps:

1. Find the mass of one blade by dividing the kinetic energy of the helicopter by the rotational energy per blade:

2. Use the formula for rotational energy per blade: rotational energy per blade = 1/2 * I * w^2

3. Convert the given angular velocity to radians per second: w = 37.7 rad/s

4. Substitute the values into the equation to solve for the mass of one blade.

5. Calculate the total moment of inertia by multiplying the individual moment of inertia by the number of blades.

Conclusion:

By following the steps and using the formula for moment of inertia calculation, we can determine the total moment of inertia of the helicopter blades. This value is crucial for understanding the rotational dynamics of the helicopter and ensuring stable flight.
