Americans "teach" their helicopters to land on the relief surface

50
The US Department of Defense's promising project agency (DARPA) presented a system that allows the helicopter to land on almost any hard surface without danger of damaging the rotor, reports Rossiyskaya Gazeta.




“Instead of a standard wheeled chassis or metal skis, engineers suggested an adaptive“ four-legged ”device, each bearing of which is equipped with power sensitive sensors. When landing, they determine the angle of deployment so that the helicopter body remains in a horizontal position, ”the newspaper writes.

If necessary, the robotic system can tilt the board in different planes, while minimizing the risk of the ground touching the blades.

During takeoff, the supports are pulled up to the “belly” of the car, minimizing the effect on the aerodynamic parameters.

“Our equipment, mounted on an unmanned helicopter, has successfully demonstrated the ability to land and take off from sites with difficult terrain. With traditional chassis it would be impossible. ”- said the project manager Ashish Bagay.

According to him, “an innovative chassis reduces the risk of damage to the aircraft during hard landings at least five times as compared with the usual one, ensures a stable landing and take-off on slopes up to 20 degrees, and also simplifies the pilot’s task during a deck landing.

He also noted that this "landing gear can be installed on helicopters of almost any type and size."

    On slopes up to 20 degrees? Better carry a relief platform with you! laughing
    A bullet hit, or, moreover, a projectile, will render all this "brilliant" invention unusable.

      Not a bad idea, but it will make the aircraft heavier, making it impossible to take off on an airplane. Although in Amer, the army apparently does not practice the latter.
      In those photos that are presented, the design takes about 1/4 of the weight.

        Well, if skis are instead of wheels, anyway, takeoff "by plane" is not used.

        And from my point of view, a rather interesting design. Technology does not stand still: the wheeled chassis has supplanted the ski, and now many-legged will displace the wheeled.

        Not only this. The ability to roll back or deploy the car even with idle engines must be left.

        More than just not bad.
        - Great idea! good
        Especially if it is implemented for any small helicopter-type UAVs (which we see in the video), for which the choice of landing sites will be much easier.

        Well, this is far from a fact, if the wheels are fastened to the ends of these steered racks, instead of plugs it will fly like a pretty one.

        Well, even if at least 3/4, this is a technology demonstrator. In general, it is surprising that on top of this design there is a helicopter, not a cable bay, but a transparent box with sensors.

      After hitting "Pines", "Shell" or "Attack-O", even the Apache "sits" on the rocks and on the forest. Sometimes "Needles" are enough for "landing on difficult terrain", however, often in fragments.

        Jokingly, but in mountainous areas such equipment can give a good advantage ...

        Although - it will complicate the equipment, design and their maintenance ...

        Just lower the cable from the winch.


        The cable does not always help, agree.
        There has always been a need to land on a not entirely ideal site. Usually made freezes. The cargo was dropped, BP, people were landing.

      Yes there is of course. And they did not immediately come to the retractable landing gear and to the free-carrying wing without struts and braces. And stomp, as I understand it in this direction ... By the way, spiders do not have muscles in their paws - chitin tubes straighten with fluid pressure. With a decrease in pressure, they bend themselves. Designs do not have to be metal. Maybe we'll see a chassis made of oblong balloons smile

            Do not like, it will be right. This is the first.
            And the second - why write nonsense? It is a complex technology that allows MEASURING the angle of heel of the helicopter and ADJUST it, i.e. about feedback system. All newness lies precisely in this, and not in jacks and telescopic legs.
            This is a dual-use technology that will certainly find application in civilian life. To help the same spinal cord is a huge plus. Have you seen the eyes of 20 year olds who know they will no longer be able to walk? Now imagine that they will have "mechanical legs" that independently support the vertical position of a person? What is not a reason to rejoice?

              -------------------------
              What is so difficult you saw in the photo of the "dumb drone" (this is how I translated the name on board)? What complex system is there? Feedbacks in mechanics have been used for a long time, just before they were mechanical or electromechanical, now they were helped by sensors and a computer, this principle has long been used in TEBS, a vehicle stabilization system. We just decided to help not quite qualified pilots and expand the capabilities of the turntables ... As for the lever air suspension, they are also a very modern design, they allow the Korean super-duper tank to walk on the slope ... Telescopic legs why confuse you? Place the same sensors on your heels and when you touch, they send the same feedback signals to the control unit, and from there to the compressor and air distributor, which will supply the right amount of air ... Anything else to chew? Or will you guess further?

          But do not "catch" people like a butterfly net, because it is not so easy to hover, the weather is not always ideal, but to work in calm conditions when loading. This is a big difference.

    Not bad "invented", although G. Wells was closer to the topic, since a combat tripod can be lighter (three not four) and besides, the tripod adapts better and easier to the surrounding landscape. At the same time, it is possible to use only the movable attachment point, which changes the angle of inclination of the entire flying vehicle, instead of controlling each leg-paw separately. )))

    It was more expedient to make a tricycle scheme. With it, the emphasis on all "legs" is always guaranteed, and the automatic load distribution is simpler. Each leg can have its own T-shaped legs, which together will give the support additional stability.
