I spent some time indoor of the air show. I discovered this interesting item. This model is displayed by Aviation Industry Corporation of China. It looks like a sci-fi flight vehicle appeared in films like Avatar. But the concept is quite old, which could dates back to 1940s. It was quite popular then. Focke-Wulf VTOL Project is one of them. Whether this project could be carried out depends on if China can properly handle the control part. Hopefully, this helicopter could fly some day near future.
