      I had theories on how it yaws and he confirmed it as well as my concern that if you put more torque on one rotor than the other its going to roll as the rotor your putting more torque on moves to the vertical.

The little "tail strike gauge" under the rudder I reckon should be called a "tell-tail"! - As it will soon tell the "tales of woe" that the rear end endured if you were ham-fisted with the cyclic during landing! What an amazing and very clever lifting machine, that can lift more than it own weight, - WOW!

  • @paullangford8179
    @paullangford8179 Год назад +1

    Tail rotor only takes about 10 %, NOT 30 %. but even that is a significant improvement of efficiency. The swept area of the blades is a lot more than usual for a helicopter of this power class (1350 HP), so the downdraft is lower intensity spread over a larger area. The characteristic of the Flettner intermeshing rotor system is that it tends to a stable hover, and requires pilot input to move, unlike most other helicopters.

  • @atomicskull6405
    @atomicskull6405 Год назад +1

    In case anyone is interested on the CH-47 Chinook yaw is by opposing left and right cyclic at the front and back rotor and fore/aft movement is by increasing collective on one rotor and decreasing it on the other. There is also a "longitudinal trim actuator" that applies fore/aft cyclic to both rotors but this is only used to pull the nose up in forward flight and push it down in hover (the CH-47 wants to hover nose high) and it's controlled by the electronics not the pilot.

      That’s correct. After World War II, the US conducted “operation paper clip” which involved bringing the brightest minds from Europe over to the United States to aid in our lead of the arms race as we moved into the Cold War. One of these minds was Flettner. He was a key person in helping Charlie Kaman build and develop the H-125, H225, The Husky, and finally the Kmax.

    Question for someone. I gather the blade is solid wood (laminated) aside from an internal channel for the control rod. Where is the centre of gravity chord wise? On a single blade machine operated with a swashplate the CG is about 25% back from the leading edge. Excellent video thank you.

    Excellent 'walkaround' Gents, thank you. Although trying to imagine the actual physics of this machine in flight, does leave me wanting a larger colouring book& more crayons. - eg. Is ground resonance 'a thing' with this rotor system, or at a million bucks per blade, does that kind of madness only affect your bank manager's desk legs?
    Fabulous machine, a working madness to the benefit of all - in skilled hands, a marvel - but in mine, shameful wreckage : )

    • @Maverickib
      @Maverickib 2 года назад +2

      Ground resonance is usually a byproduct of lead/lag hinges falling out of sync. So I don't believe this rotor system is susceptible to that, at least in the traditional sense. Though it might still be possible since the wheels have oleo struts, usually not something you see unless impact dampening is required (the source of ground resonance).

  • @rwlewko
    @rwlewko 2 года назад +1

    Mark: one question I have that I wish you would ask your guest is, since the aircraft creates yaw by increasing the angle of attack on the rotors on one side, thus creating more lift on that side and the pilot has to use the cyclic to counteract that lift I surmise that the action of the cyclic doesn't create as much yaw as the increased angle of attack. Is this correct?
    An addendum to this question is: is there a difference between how this helicopter's cyclic acts compared to a normal helicopter? Same for the collective?
    Please would you have the pilot expand on this topic?

    • @kbrashar
      @kbrashar 2 года назад

      Hello Robert. Good question. In regards to the flight controls, they all work similar to other helicopters. Pedals create a yaw movement , cyclic is directional control, and collective is mainly your up and down. Of the three inputs, pedals and yaw are by far the least effective in the Kmax. This is impart due to large surface area that is being moved and the although the “torque effect” works to cause the helicopter to yaw in the opposite direction , it is not nearly as effective as a standard tail rotor.
      Their are benefits to having no tail rotor, but it comes with a cost :)
      I hope this answers your question.

  • @1stMunga
    @1stMunga 2 года назад +1

    Kevin; I am at a "Loss" as to why the In-Flight Tracking Actuators are no longer used. Their NOT being utilized constituted a Red "X" or Grounding Condition, in the past. Now, a go-pro, in flight shows the Rotor Blades out of track and causing the thing to appear to beat the crap out of itself. Are there simply no parts to keep it up to date? I could track this thing, with the help of the Friction Dampers, to smooth as a Baby's Butt. Not only a smoother Coning Angle but.....the Fuel parameters were greatly improved. Just wondering.

    • @kbrashar
      @kbrashar 2 года назад +1

      Hello Zobee. We absolutely still use the in-flight tracking system. We just didn’t get into the details of that component in this video. There are two tracking motors mounted to each rotor head just below the blades which allow the pilot to visually track the blades in flight. A must in a Kmax :)
      Hope that answers your question.

      Rotary version of the Transavia PL-12 Airtruk.... all the way down to lifting loads more than its own weight, and comparable top speed.

    Please help me out understanding that those blades don't hit the other engine.

      They are angled away from each other. When it's flying you can see it, each blade passes over the other hub and the blades interlock between each other. .

    Imo this is counter-rotating with style.

    How can the rotor be 90 degrees from each other and counter rotate?

      If they went in the same direction they would hit each other in 45 degrees. When one set is east west, the other set is north south and they are angled outwards so that they can inter-mesh.

    The only thing left out (that i wanted to know anyway) was lifetime hours on the blades. At $2m you would hope for many!

      I'd expect at least 10 years or several thousand hours.

      @@skywagonuniversity5023 thanks. I've been searching but no luck yet. If it was the 3000 tbo that would be $660 an hour, so suspect they last 6000 to 7000 hours. Wood hey! Would love to see a video on their construction!
