Characteristics of rolling-wing helicopter

The airfoil rolling machine uses the principle of cycloidal wheel, which is to adjust the airfoil angle during the airfoil turning process. That is to say, when the wing rolls, the angle between the wing surface angle and the connecting rod is constantly changing, and when it turns to different angles, the leaf surface angle also changes. By changing the direction of the airfoil, the thrust in the corresponding direction is generated, which means that the thrust can rotate 360 degrees. The rolling wing machine is rolling and rotating, so it can release the thrust in 360 degrees, but the propeller is much smaller and can only be in one plane (of course, there are helicopters that demonstrate inverted flight, but only provide thrust in two directions). Therefore, the slope of the helicopter take-off field should not be too large, otherwise the thrust direction will be difficult to adjust, and the helicopter cannot take off vertically if the slope is too large. Rotorcraft, like propeller (which can be understood as transverse propeller), has obvious advantages in low altitude and low speed, although it is not as good as jet at high speed. But, one thing. When the rolling wing of the rolling wing machine rotates at high speed, it will produce gyro effect and reduce the flexibility of operation. I don't know how to deal with this, because so far, there are few cases of wing rolling machine in the public research materials, and I hope there are experts to answer them.
