The Aero-Geometric Trap: Why Potential Flow Solvers Get Exploited in UAV Optimization

When global optimizers are coupled with low-order vortex lattice methods (VLM) without geometric regularization, 35.5% of evaluations waste compute exploring chord-inverted topologies with a 29% penalty in max L/D (12.89 vs 18.15) without solver divergence. How I formulated C1-continuous Hermite manifolds to enforce geometric invariants across 10,087 evaluations, and what post-submission 3D RANS CFD revealed about a 124% parasite drag rise at winglet junctions.

Programmatic 3D CAD: Interfacing LLMs with Parametric B-Rep Kernels

Generative 3D polygon meshes cannot be manufactured on physical CNC mills or lathe tooling; real engineering requires Boundary Representation (B-Rep) solids with exact datum planes, mate constraints, and editable parametric feature trees. Architecture of onshape-mcp: a Model Context Protocol server connecting LLMs to the Onshape cloud REST API for bidirectional feature-tree tracking and topological constraint enforcement.

Despinning a 155mm Artillery Shell in 1.2 Seconds: 7-DOF Dynamics and Terminal Guidance

At 300 rps (18,000 RPM) muzzle rifling spin, canards cannot execute coherent trajectory corrections without actuator saturation. I decoupled the forward steering head from the projectile body using a 1-DOF roll-isolated collar on dual angular contact bearings. Supported by passive permanent magnet eddy-current damping, the collar attenuates roll from 300 rps to below 5 rps in 1.2 seconds, enabling terminal Augmented Proportional Navigation (APN) and 16-state EKF estimation through 25-second GNSS denial windows.
