    How cool! I hope it becomes a reality.

    I personally do not. The design/configuration of the concept (the one closest to the camera) is not very efficient in terms of volume and would be difficult to fold for adapting into a naval variant.

    I expect AVIC to develop a new generation helicopter eventually whether it's a coaxial+pusher propeller or some kind of tilt rotor or they may develop both, but a combined pusher propeller+non tilting rotor is not a very efficient use of aircraft weight and volume in my opinion

    It's called a Transverse rotor configuration although this one has been modified with the addition of pushers.
    We also see the older propeller nosed chopper model on display.

    Edit: There is also a discussion about it in the X-plane thread. Maybe it can be merged ?
    Also, does anybody have a source for the image ?


    While the transverse rotor configuration does have disadvantages (higher weight, higher volume), it also has a few advantages that make it usefull.

    Compared to traditional helicopters:

    1. It has no tailrotor, which usually needs up to 10% of your engine power

    2. It has smaller rotors, a push prop and wings. This means that it has a higher maximum speed and is more efficent when flying. (as opposed to hovering.)

    These are exactly the same advantages the US also looks for in the FVL/JMR/JVX programs. These are absolute gamechangers.

    Compared to an S-97/SB>1 concept, which would be much more compact and lighter, it has the following advantages:

    1. Its massively simpler. This means its achievable and in a shorter timeframe and also cheaper, at least initially.

    2. Just like a tiltrotor, it has wings and this an even lower diskload for higher efficency in flight.


    Long term, a coaxial rotor or tiltrotor is probably the better way. But in the meantime a transverse rotor can bring benefits of traditional helicopters and build knowledge for your industry and military.

    US chose tilt rotor because of a requirement to fold the aircraft for use on aircraft carriers. When such a requirement doesn't exists the transverse rotor configuration might be acceptable. It hasn't yet been successfull, think V-12 and Ka-22 ( https://en.wikipedia.org/wiki/Kamov_Ka-22 ), but better analysis methods might well solve the problems.
