AI Technical Summary
⚠Technical Problem
Existing underwater navigation equipment has problems such as the inability of AUVs to achieve long-endurance and long-range operation and poor maneuverability. In addition, traditional gliders have easily damaged wings and low transport space utilization.
⚗Method used
The traditional fixed flat wing is replaced by a foldable grid wing. The grid wing is controlled by a drive motor to unfold in taxiing mode to provide lift, and folds against the surface of the fuselage in propulsion mode to reduce drag.
🎯Benefits of technology
It enables flexible maneuverability and long-term operation in complex environments, reduces the space occupied during transportation, improves the robustness and safety of the wings, and reduces the space requirements for transportation and storage.

Abstract
The application discloses a grid wing-based integrated gliding and propelling AUV and belongs to the technical field of unmanned underwater vehicles, which comprises an AUV main body, grid wings and mounting assemblies. The AUV main body is an integrated gliding and propelling AUV, and two grid wings are symmetrically mounted on the two sides of the AUV main body by a set of mounting assemblies. The mounting assembly comprises a base, a main shaft, a wing folding shaft, a first driving motor and a second driving motor. The base is fixed in the inner cavity of the AUV main body, and the main shaft is rotatably arranged in the base. The main shaft is driven to rotate by the first driving motor to adjust the attack angle of the grid wing. The wing folding shaft is arranged at the outer end of the main shaft and is fixedly connected with the grid wing. The second driving motor is used for driving the wing folding shaft to rotate to realize the folding or unfolding of the grid wing. The two driving motors are controlled by a posture adjusting system in the AUV main body. The grid wings are foldably mounted on the integrated gliding and propelling AUV, the lifting force requirement in the gliding mode is met, and the influence of the resistance on the propelling mode caused by the fixed flat wings is solved.
