The architecture and key technologies of the digital twin system of helicopter based on cloud-edge-end integration

As a typical complex equipment system, helicopter is designed and optimized for its physical entity, and condition monitoring and predictive maintenance is a challenging task. As the link between the physical world and the virtual world, the digital twin technology can express the helicopter with high precision, high real-time and high integration in the virtual space, so as to promote the further study of the helicopter. In this paper, the architecture and key technology of the digital twin system of the helicopter equipment with cloud edge integration are described, and the real-time simulation of the helicopter equipment is realized by making full use of the edge computing power, reducing the cloud computing demand, improving the whole system's computing power, reducing the time and economic consumption in the process of data transmission.
