WebJun 11, 2009 · The twirling seeds of maple trees spin like miniature helicopters as they fall to the ground. Because the seeds descend slowly as they swirl, they can be carried aloft by the wind and dispersed over great distances. Just how the seeds manage to fall so slowly, however, has mystified scientists. WebThe tail rotor plays an important role in helicopter aerodynamics. As the engine causes the main rotor to spin, each angular impulse generates a torque on the main rotor. According to Newton’s third law, the same angular impulse and torque is exerted against the engine and the body of the helicopter, but in the opposite direction.
