      Your explanation supports me in my thought, that helicopters feel like a videogame - becoming as good with the controls as you can, clunky at first, but improving by the hour. I would like to make the helicopter licence one day, I just need to make some very good money for that. =3

    • @disgruntledgrunt241

      Yes it is very expensive, especially compared to fixed wing (planes) which is still significantly higher than when I was flying in the late 80's through the 1990's.

    Finally a video that actually explains how it maneuvers. I was thinking, “there’s no way they rapidly change the pitch of the blades to lean a certain direction” but I stand corrected and in awe. Very cool.

  • @tsweens13
    @tsweens13 4 ปีที่แล้ว +1

    the other problem is that advancing in any direction via roll or pitch means the rotor lift isn’t facing perpendicular to gravity so more collective/lift is needed to counteract it. As well as that, when going down the rotor speed can increase to the point where the tips will break the sound barrier and slow down again roughly 50 times every second, resulting in a devastating loss of control and extreme noise. worst case scenario could involve the rotor blades snapping off or the control rods breaking because of the increased lift. Finally, those rotor blades have to be damn strong and slightly bendy due to the outside of the rotors going much faster than the inner side, meaning the outer edge creates more lift. Either a variably shaped aerofoil can be used with less lift ability on the inside or the rotors must be extremely flexible.

      Luis My last name is none of your business Actually its the same thing: W/S for thrust. Mouse for the ring (tilt forward/backward/sideways) and A/D for the Tailrotor. Only direct up and down is done with the mouse in the basic position and more/less thrust. So I think in general not as different ;)

    The direction the swashplate tilts relative to the cyclic is actually determined by how the pitch links are rigged. Most modern helicopters have the pitch links rigged in such a way that they automatically adjust for gyroscopic precession/phase lag so that the swash plate can just tilt intuitively relative to the cyclic controls.

      that's great. but the phenomena behind (gyroscopic precession) cannot be eliminated, responsible for all rigging or other approaches to make swash plate tilt intuitively relative to the cyclic controls. For beginners demonstration in this video will help them build solid understanding, isn't it?

    Another factor to be taken into consideration when moving from the hover
    and transitioning to forward flight is the relative speed of the blade
    moving forward (the advancing blade) in the same direction as the
    helicopter and the blade on the opposite side of the rotor disc that is
    moving backwards (the retreating blade). Lift is generated by the shape
    of the aerofoil, the area of the aerofoil surface, the angle of attack
    and the speed through the air. In forward flight the advancing blade has
    its speed added to the forward speed of the aircraft and the retreating
    blade has its speed subtracted. Unless corrected, this would cause the
    helicopter to roll over as far more lift would be produced on one side
    of the disc compared with the opposite side. This is controlled at the
    rotor mast head by allowing the advancing blade to move backwards
    slightly relative to the rotor disc spin and the retreating blade to
    move forwards. Thus less lift is produced on the advancing blade, more
    lift is produced on the retreating blade which evens out the lift on
    both sides. This adjustable movement is controlled at the blade root.

      that’s why the dual rotor design is more robust. With the chinook’s contra-rotating rotor sets, they both produce lift on opposite sides and it almost cancels itsself out. beautiful.

    Great video, but unfortunately horribly wrong on the physics behind how the swash and blades cause the heli to tilt. At 5:06 it says this is due to gyroscopic precession, which is a very common mistake people make. The actual reason is due to aerodynamic forces, and is much more complex than gyroscopic precession.
    One important difference is that gyroscopic precession *always* acts at 90°, whereas the effect on a helicopter depends on the rotor head design, and can vary significantly from this (such as a 72° lag on some models).
    Another mistake is that generally when the swash tilts forward, the heli will tilt forwards because the engineers designing the heli know about this effect and account for it mechanically in the linkage between the swash and the rotor head.

    • @MrT------5743
      @MrT------5743 7 ปีที่แล้ว +1

      He didn't explain that the torque produced at 4:25 was the result of aerodynamic forces, but did correctly show that the torque at 5:06 when applied to a rotating rotor then gyroscopic precession is 90 degrees or sideways to that torque.

    • @og_myxiplx
      @og_myxiplx 7 ปีที่แล้ว +4

      That's my whole point, the way a helicopter rotor blade reacts has very little to do with gyroscopic precession, the point he makes at 5:06 is fundamentally flawed. Go read any text on rotary aerodynamics, this is not how it works.
      There's a simple way to explain why it's wrong: Gyroscopic precession always acts at 90 degrees to the force applied, but a helicopter rotor often does not react at 90 degrees to the input. In fact, the rotor lag will vary depending on the head design and can be between 72 degrees and 90 degrees.
      The effects appear similar on the surface, but the underlying physics and reasons why this happens are totally different. This is a very common mistake, but unfortunately utterly incorrect if you're trying to explain how a helicopter rotor actually works.

    The first video on how airplanes fly rein enforced my knowledge. It made me remember how important the shape of the wings are to the flight of an aircraft. The angle of attack is important too because it indicates whether or not the aircraft will be lifted or will be descended. In addition I remembered how slats and flaps work and the rudders and it’s important to the YAW of an aircraft.
    The helicopter video reinforced a little bit of knowledge that I already had.
