If the rotor blades of a helicopter stop spinning while in the sky, the helicopter will begin to lose lift and descend rapidly. It would enter a condition known as autorotation, where the helicopter can glide down safely by allowing the rotor blades to spin freely due to the downward motion of the aircraft. However, without engine power, the pilot would need to manage the descent carefully to achieve a safe landing. If not handled properly, it could lead to a crash.

What happens if the blades stop spinning on a helicopter when it is in the sky?

If the blades stop spinning on a helicopter while it is in the sky, the helicopter will enter a state known as autorotation. The helicopter will start to descend as the unpowered rotor blades rotate due to the upward flow of air. The pilot must carefully manage the descent and attempt to safely land the helicopter.


Do the rear blades of a helicopter lift the helicopter?

NO, the main rotor does the lifting and the small rear propeller is used to stop it spinning around and help with steering it.


How stop RC helicopter from spinning?

To stop an RC helicopter from spinning, you can adjust the trim settings on your transmitter, specifically the yaw trim, to counteract any unwanted rotational movement. Additionally, ensure that the rotor blades are properly balanced and aligned, as uneven blades can cause instability. If the helicopter is still spinning, check for issues with the gyroscope or electronic stabilization systems, as these components help maintain stable flight. Finally, practice gentle control inputs to stabilize the helicopter during flight.

When a train won't stop would it work if a helicopter hooked a chain to the train an pulled back?

A very larg helicopter may be able to take off with an added 50,000 lbs. of weight. A good sized modern train is going to be significantly larger than this. The helicopter's blades would likely give out as they are suddenly reversed if you just "slammed on the brakes" so to speak. If you had the helicopter going at the same speed as the train, and slowled the helicopter down as much as possible, the train would eventually stop if the locomotives were not powering the wheels (it would stop without the helicopter, too, and would be infinitely safer for the helicopter pilot). If the locomotive is powering the wheels, the helicopter's not going to do a whole lot.


What force causes a spinning top to stop spinning?

The force of friction between the spinning top and the surface it is on causes it to stop spinning. Over time, the energy of the spinning top is transferred to the surface as heat, resulting in a decrease in the top's spinning speed until it comes to a stop.


What would happen if the coils in a generator stopped spinning?

If the coils in a generator stop spinning, there would be no change in the magnetic flux passing through them, and thus no induced current would be generated. This means the generator would stop producing electrical energy.
