AI Technical Summary

Technical Problem

Existing drones suffer from insufficient lift, short endurance, and poor adaptability in thin atmospheres, problems that cannot be effectively solved by current technologies.

Method used

By installing jet devices in key areas of the UAV wing, high-pressure airflow is injected into the airflow boundary layer, delaying airflow separation, increasing the lift coefficient, and using jet momentum to compensate for the density defects of the thin atmosphere, combined with a real-time closed-loop control system to achieve lift enhancement.

Benefits of technology

It significantly enhances lift in thin atmospheric environments, exhibits strong adaptability, reduces energy consumption, and simplifies engineering implementation difficulties and costs.
