Question

What includes incidents generally categorized in other areas, such as a foreign object damaged engine, which sheds parts, or a helicopter rotor blade pocket failure?

Answer 1

Helicopter rotors store rotational kinetic energy that must be maintained to ensure lift during flight. Pilots can use the gravitational potential energy of the helicopter to replenish this energy and avoid crashes.

Step-by-step explanation:

Helicopter rotors store rotational kinetic energy in their blades before takeoff and maintain it throughout the flight. The engines of helicopters are not powerful enough to provide both lift and sufficient rotational energy to the blades simultaneously. If the blades slow down below a critical angular velocity, they lose lift and cannot regain it immediately. To avoid a crash, pilots can use the gravitational potential energy of the helicopter to replenish the rotational kinetic energy of the blades by losing altitude and aligning the blades for a spin-up during descent.
