can a helicopter go upside down without crashing?

Question

YOu tell me. I have seen it on some movies but you know

Answer 1

Very few helicopters can go upside down for long. Only one civilian helicopter is rated to do it. Military helicopters are different they are more suited for that kind of thing, good luck getting to the truth though. A helicopter can not stay and fly upside down but can flip upside down if the pilot can keep a positive load on the rotorblades the whole time. The rotor must stay loaded with some weight though on most helicopters or the blades will be alowed to deflect to far and will cut the main shaft of the helicopter and seperate the rotor blades from the helicopter. Not good. once helicopter, now lawn dart.

Answer 4

Sorry Zach. The Comanche got canceled. I felt I had to give you a thumb down for that bit of ignorance. I wasn't alone, either. Full-scale helicopters can fly inverted, but not for long. It's more of a trick to demonstrate agility, not a common maneuver. They limit the upside down time to loops and barrel rolls. Some R/C model helicopters are another story. They can sit there upside down for quite a while.

Answer 5

Not many can. Actually, if I am not mistaken the first helicopter that was capable of inverted flight was not until about 10 years ago. Before that movies used model helicopters to fly stunts that were immpossible. In fact, most helicopters rotor blades would break off in flight if they attempted this feat because they were never meant to fly upside down. But, yes, there are a couple of helicopters that can fly upside down now.

Answer 6

Only models can fly stable and inverted.

The problem is that when under negative g loads the rotors would flex into the tail boom, or the body in the case of the Chinook.

Lots of helicopters can loop and roll, especially the more modern ones like the Apache and Lynx which have stiff rotors compared to things like the UH1.

The CH53A and the Lynx are among those looping and rolling in the videos below.

Answer 7

the maneuver must maintain a positive g-load, then the helicopter can fly upwards down. I am not aware of any helicopter capable to fly in straight flight wheels /skids/ up. its because the helicopters don't have negative angle of attack of rotor blades. only RC models do have this feature.
so> eurocopter tiger performs a loop, apaches and those small like bo 105 can do a barrel roll.

Answer 8

Some have been known to loop or do a barell roll. Mostly military aircraft. They can't maintain inverted flight by design. The lift created by the main rotor is up in relation to the fuselage in normal flight. So, inverted, it would be pulled towards the ground. Maneuvers like these require a good amount of altitude. The blades are made to have a range of travel from about flat pitch and up. They don't do negative pitch, flip over, and the rotor does not spin backwards. But some people believe that they do that.

Answer 9

If you are an Helicopter pilot you can better understand the helicopter aerodynamics. You got to remain in translational lift to keep the rotor loaded.
There are few helicoptores like Links and Apache etc which can do looping manouvres but sustained inverted flying is not possible on this machine due to so many ingerent problems.

Answer 10

Many military rotary wing craft can roll, but they cannot fly upside down. It is done at airshows strictly as a trick, but these craft generally have modified blades and have sacrificed their speed, lift, and manuverability. People who make movies, of course, are like Superman: They can do anything.
