Overview

The fully autonomous UAV is in progress. The CAD is complete in Onshape, and the current work is simulation testing so the design can be durable, reliable, and fit for real-world use. It has not flown. More simulation results are on the way.

Validation

The checks underway are computational fluid dynamics in SimScale, stability and performance analysis in AVL and XFOIL, and structural checks.
