  2. What are the advantages and disadvantages of autogyro aircraft?

    aviation.stackexchange.com/questions/46103

    Nov 26, 2017 at 2:23. 1. Autogyros survive just as fun aircraft, capable of very slow but safe flight and very suitable for recreational flight. Bensen-type gyros, with fixed-pitch, seesaw rotors, are –with very few exceptions– the only extant type. Concerning speed, the autogyro is limited (as the helicopter) by retreating-blade stall, and ...

    aviation.stackexchange.com/questions/36965

    Look at rc twin rotor gyros. They perform quite well. Instead of having articulated blades they are fixed and counter rotating at the end of opposing booms .The rotors are shorter and spin much faster on ground roll for takeoff.

    Typically Autogyros experiencing "negative Gs" will crash. I wonder if an Autogyro with wings would work as a fail safe for this situation? Would it allow the pilot to recover assuming this

  5. What are the uses of gyroplanes? - Aviation Stack Exchange

    aviation.stackexchange.com/questions/25676

    18. From my understanding, a gyroplane (autogyro): Is a rotocraft. Uses an unpowered rotor for lift generation, instead of wings. Uses a propeller for horizontal translation like an airplane. Cannot take off vertically or hover contrary to an helicopter. Can land vertically like an helicopter using rotor inertia.

  6. How to convert a PPL (Gyrocopter) to a PPL (Helicopter)?

    aviation.stackexchange.com/questions/60037/how-to-convert-a-ppl-gyrocopter-to...

    The minimum hours will require a detailed reading of the specific FARs. You can use hours logged in a gyroplane to meet requirements for hours in "rotorcraft" or "any aircraft", leaving you with only the hours specifically required to be in "helicopter" as your minimum training. You will probably exceed the latter before a CFI is willing to ...

    aviation.stackexchange.com/questions/44104/how-to-calculate-the-amount-of...

    T = 2v2 ⋅ A ⋅ rho T = 2 v 2 · A · r h o. where T is the thrust of the rotor, v the sink speed in vertical auto-rotation, A the 'disk area' (that swept by the blades) and rho the air density. Thanks for you answer! I understand that the in steady horizontal flight the thrust is equal to the weight but how can it be calculated.

    aviation.stackexchange.com/questions/27927/how-much-could-human-power-add-to...

    One has to look at the total energy requirement of the gyrocopter. In this instance it is a 80 kW powerplant. A human power plant would be incapable of a sustained output of more than 1kW, therefore I would conclude that the impact of augmented human sourced power would be less than 1% and therefore insignificant.

  10. theory - Can a gyro-copter soar? - Aviation Stack Exchange

    aviation.stackexchange.com/questions/27291

    Well, provided that the air is not just raising, but raising faster than the aircraft needs to descend to maintain flight. I am not sure what kind of L/D gyrocopters have. you don't have to shut off or null the engine to glide. @rdp A 747 can soar; in theory. I'm thinking about 'for all practical purposes'.

  11. I believe what the comic is referencing is Mast Bumping.Rotor blades are very flexible, and for a bunch of reasons, are free to pivot around the mast.(The shaft the blades are spinning around) In normal flight, the blades are held taut by centrifugal forces and the weight of the rotor craft they are supporting.
