Drone with ring assembly

This invention describes a drone with its propellers fully contained within a protective ring structure. The drone's body is formed by multiple stacked rings, and it's designed to carry and deploy items from internal storage. The patent claims specifically detail this unique ring-enclosed propeller configuration.

Why it matters: Since 2017, increased focus on drone safety and indoor/delivery operations makes enclosed rotor designs more appealing, as they reduce prop strike risk.
