AI Technical Summary

Technical Problem

When high-speed aircraft are launched underwater, the porous exhaust technology has difficulty in quickly building and maintaining a stable air film in extreme environments, resulting in attitude instability and affecting the aircraft's load reduction and stabilization effect.

Method used

The structure employs a ventilation-based load reduction and stabilization system, which includes an exhaust compartment and a sliding microstructure group. Gas is discharged through exhaust vents to form bubbles, which expand and merge in the grid gaps to form an air film. The superhydrophobic coating and sliding microstructure are used to control the bubble migration path, thereby achieving rapid construction and stability of the air film.

Benefits of technology

It improves the attitude stability of the aircraft, reduces the peak hydrodynamic load, and enhances the motion stability of the aircraft during underwater launch.
