Event Horizon-3

Event Horizon-3 (EH-3) is the third aircraft in a generation of large, endurance-based, autonomous quadcopter developed by the SUAS@STEM team. It features a 2-meter, tri-foldable airframe. When paired with a propulsion system designed for high efficiency, EH-3 can achieve impressive flight times while maintaining a compact form factor that fits snugly in a single backpack.

As the latest iteration in the Event Horizon series, EH-3 incorporates lessons learned from the previous aircrafts, representing a significant step towards efficiency and mission capability.

Key Design Principles

Efficiency: Large-diameter propellers and a lightweight, custom carbon fiber airframe allow for a high specific thrust efficiency and long-endurance flights.

Deployability: Extremely foldable arms allows the aircraft to collapse for transport while deploying quickly and tool-lessly into its flight configuration, despite of its large size.

Modularity: The base platform supports additional sensors and different payload configurations as the aircraft evolves through many generations of students.
