  • No. Think about it. The chopper is kept airborn by the rotating blades creating higher pressure below them than above them. Upside down, assuming you could get it to turn upside down, the chopper is being forced to rapidly accelerate towards the ground so you end up in a powered free-fall. Not pleasant.

  • The answer is yes and no. Many military helicopters can perform a vertical loop, where they are inverted momentarily. However, I do not believe there are any helicopters that can sustain inverted flight. The reason for this is not that the rotors would push air upward--the rotors can be rotated to direct air downward. The reason why it can not fly upside down is because the rotors are very flexible, and if the helicopter were upside down, the rotors would hit the tail of the helicopter, thus breaking apart the helicopter before it even reached the ground. I believe the military is working on helicopters with stiffer rotors that could fly upside down. However, this is still years away. Additionally, inverted flight does not benefit a helicopter nearly as much as it does an airplane. Whereas an airplane can increase maneuverability substantially by using inverted flight, helicopters do not need inverted flight to be maneuverable.

  • Yes it can.
  • yes all they need is enough altitude and speed
  • it could but not for an extended peirod of time nor with control of where it is going, but it could happen in a crash landing or a helicopter doing a flip not flying upside down, plus the engine won't work and the gas in the gas tank would go up and leave the intake valve dry

  • Well, a chopper can flip, but fly in that position? I don't think so.
  • There are very few helicopters that are able to barrel roll and loop the loop, they must be of a rigid rotor design though, examples include Westland Lynx, AH64 Apache, Bo 105.
  • Yes but they do have difficulty turning upside down or turning a somersault.
  • Yes all it needs is a set of harrier engines attached to the top so that when it gets upside down the harrier engines will keep it in the air another posibility is that you could add a hotair baloon to the bottom and inflate it mid flight so it is ready to keep you in the air when you turn upside down
  • About as easily as a plane could fly backwards. But the laws of physics allow for the possibility of loops---not sure about rolls though..
