Each year, the ADL Design Challenge takes on a different fixed-wing UAV design problem. Here’s what previous cohorts have worked on.

2025

High-Endurance Mapping UAV

24 participants · 4 teams

Teams designed a fixed-wing UAV optimized for maximum endurance over a defined survey area. The winning design achieved 47 minutes of flight time on a single battery with full sensor payload. Key innovations included a neural-network-optimized wing planform and a novel propulsion-airframe integration.

2024

Urban Delivery Platform

18 participants · 3 teams

The challenge focused on designing a compact fixed-wing UAV capable of operating in constrained urban environments. Teams explored hybrid configurations, VTOL-to-fixed-wing transitions, and automated landing approaches. Two teams successfully demonstrated autonomous flight in the Stanford test area.

2023

Inaugural Edition - Reconnaissance UAV

12 participants · 2 teams

The first ADL Design Challenge brought together a small cohort to design a surveillance-class UAV with extended range and low acoustic signature. This edition established the program's core methodology: parametric design, AI-driven optimization, and rapid physical validation.
