   The machine, the hit of the show, performed a series of maneuvers including bowing to the crowd." ... Width: 57 ft 2 in (17.42 m) overall with rotors turning; Height ...

3. DC injection braking - Wikipedia

   en.wikipedia.org/wiki/DC_injection_braking

   Large rotors and loads with a high moment of inertia may take a significant amount of time to stop through internal friction alone. To reduce downtime, or possibly as an emergency safety feature, DC injection braking can be used to quickly stop the rotor. A DC injection brake system can be used as an alternative or addition to a friction brake ...

   Drum brake (upper right) with the drum removed (lower left, inside facing up), on the front of a Ford Falcon Sprint A rear drum brake on a Kawasaki W800 motorcycle. A drum brake is a brake that uses friction caused by a set of shoes or pads that press outward against a rotating bowl-shaped part called a brake drum.

5. Coaxial-rotor aircraft - Wikipedia

   en.wikipedia.org/wiki/Coaxial-rotor_aircraft

   Coaxial rotors solve the problem of main rotor torque by turning each set of rotors in opposite directions. The opposite torques from the rotors cancel each other out. Rotational maneuvering, yaw control, is accomplished by increasing the collective pitch of one rotor and decreasing the collective pitch on the other. This causes a controlled ...

   Intermeshing twin rotors of a Kaman K-Max Video of K-Max helicopter in flight, showing the meshing main rotors in motion. Intermeshing rotors on a helicopter are a set of two rotors turning in opposite directions with each rotor mast mounted on the helicopter with a slight angle to the other so that the blades intermesh without colliding.

9. Dynamometer - Wikipedia

   en.wikipedia.org/wiki/Dynamometer

   In current (2009) applications, most EC brakes use cast iron discs similar to vehicle disc brake rotors, and use variable electromagnets to change the magnetic field strength to control the amount of braking. The electromagnet voltage is usually controlled by a computer, using changes in the magnetic field to match the power output being applied.
