Pseudo-Satellites at 20 km: The Physics, Programs, and Promise of Solar HAPS
High-Altitude Platform Stations operate in the stratosphere at 20 km — above weather, below orbital mechanics — using solar power and ultra-dense batteries to loiter for months. Here's how they work, which programs are viable, and why the sector is drawing serious capital.

Tilt-Rotor, Tailsitter, and Ducted-Fan Drones: The VTOL Hover-Cruise Trade-Off
Every VTOL aircraft must reconcile two contradictory physics demands: hover requires high blade area and tip speed, while forward flight requires the opposite. Tilt-rotor, tailsitter, and ducted-fan architectures each place their bets differently — with lasting consequences for military range and noise compliance.

UAS Traffic Management: The Decentralized Architecture Replacing ATC Below 400 Feet
The FAA provides no air traffic services below 400 feet, where drone density is set to explode. UAS Traffic Management replaces centralized control with a federated network of software intermediaries — and a decade of NASA research shows why that architecture is the only one that can scale.
