  • Awesome vid.

  • Sorry, my comment not clear: At 1:51 is an old HELICOPTER. Several reasons it falls over: 1) Narrator is correct (however equal pitch of blades there's always some static and dynamic error- as you suggest !) 2) Pendular stability: The craft 'rolls' off the compressed air cushion, which is less likely to happen with a tall rotor mast 3) slight breezes will affect hovering craft (flapping hinge would solve that). Rigid rotor models tip over but the new 'Hiller' hubbed R/C toys are perfect: Hinged

  • I don't understand the dysymmetry of lift at 1:51.

    The craft is stationary so they should have balanced it, no disymmetry of lift there if you ask me.

  • Poorly explained. As the rotor disc moves FOWARD into the on coming air, the 'advancing' blade is going faster into the wind (aircraft speed + blade rotation speed) and the other blade is slower (the 'retreating' blade). That causes more lift on one side of the rotor disc. Consequently the disc rolls over (like tilting a frisbee over). A flapping hinge reduces the lift on the advancing blade by lowering its angle of attack because the on coming air is now flowing slightly downward over the blade

  • "Poorly explained"?

    I'm glad you did the trouble of trying to understand what I'm telling/asking.

    ?

    Does the rotor disc move FORWARD (I don't think so, it even looks the craft isn't capable of rolling on the ground) at 1:51?

    Again, the craft is stationairy relative to the ground and judging by the trees there is no wind blowing, so it's also stationairy relative to the air, so how can there be dysymmetry of lift?

    Not balanced, that's what I think.

  • Check out CarterCopter and Groenbros on the web for modern gyros.

  • whats the differences beteewn a autogiro and a gyrocopter

    Asdre12344 4 years ago

  • Gyrocopter is a trade name Igor Bensen used for his gyros. Gyroplane is the official FAA designation for all of them. Regarless of what they are called they all use the same basic principals to fly. An engine either pulls or pushes the aircraft and the rotors spin freely.

  • If you are really interested in what Cierva thought process was and how he solved problems...try to htis book he wrote: Wings of Tomorrow The Story of The Autogiro Check your libray fo it. There no reprints and they are collectibles. I have two myself!!!

  • very interesting..

  • The helicopter replaced the autogyro,mostly due to its ability to hover. However autogyros are far less complex and more reliable. Currently I know of one company that tries to revive the autogyro, for people who want aircraft with STOL characteristics but at reduced price.

  • It's difficult to find infos and video on autogiro. It's very interesting and very nice, thanks!
