    Helicopters are the true flying machines. They can take off and land without the need for a runway. They can hover in the air. They can maneuver in any direction in a 360 degree space. This video will unveil the complexity and science behind flying a helicopter. After going through the physics behind the helicopter flying, you will also understand why helicopter pilots are doing an incredibly complex job.

    While going through US Army rotary wing flight school in the early 90's my instructor pilot said helicopter pilots fly by constantly correcting for mistakes they just made.

    • @marcfuchs6938

    • @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.

  • @tsweens13
    @tsweens13 3 роки тому +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.

  • @schnitzel8070
    @schnitzel8070 3 роки тому +7

    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.

    • @leathelhit

      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?

    @oc2phish07 4 роки тому +4

    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.

    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.

      It reminds me of a common problem with Porsche's 911 models, 996 & 997, that had RMS failures - the Rear Main Seal, which was a ball bearing system part similar to what we're talking about here. They would 'run dry', explode & cause catastrophic engine damage. I ain't no genius but in a car that's bad. In a helicopter it's gonna be shit ya pants time!
