This invention discloses an aerial traction propulsion
system with
beacon guidance function and its control method. The
system includes a
guidance control end carried by the towed object and a guided propulsion end serving as the aerial flight power source. The two ends are physically connected by a traction
rope and transmit data through a
communication link. The
guidance control end generates guidance information and sends it to the guided propulsion end, which adjusts its flight state accordingly to maintain the traction configuration. The
system has a manual mode and an automatic mode. In the automatic mode, the guided propulsion end performs a two-layer control of speed feedforward following and
lateral deviation correction. The automatic mode includes two stages: heading hold and heading follow-up. Once heading follow-up is entered, it is irreversible. The system achieves safety protection through distance
anomaly detection of the dual-end position data and communication disconnection
timeout. This invention does not require complex sensors or dedicated thrust devices on the propulsion end and can be implemented using a general-purpose flight platform, making it suitable for various scenarios such as hang gliding, surfing, and skiing.
