Weasel is our first high speed project in our path towards making a fully-reusable, student-built supersonic UAV.
Record-Breaker
The current record holder for the fastest aircraft in the RC category is Niels Herbrich, who set the record with a jet-powered model aircraft that reached a speed of 749 km/h (465 mph). This achievement, was recorded on August 23, 2017, in Rothenburg, Germany.
Design
Weasel’s design was developed using CADO, our in-house conceptual aircraft design software, allowing us to optimize aerodynamics, stability, and structural efficiency. Through collaboration with professors and consultation with industry professionals, we refined the aircraft to achieve high-speed performance while maintaining reusability.
Carbon Composite
Weasel’s airframe is constructed primarily from carbon composites, providing an optimal balance of strength, stiffness, and lightweight. This material choice minimizes structural weight while maintaining the durability needed for high-speed flight and aerodynamic loads. Additionally, its high strength-to-weight ratio contributes to improved performance, ensuring Weasel remains both fast and structurally resilient.
Software
Weasel’s software is designed to enhance flight stability, control, and data acquisition through machine learning-augmented systems. It processes real-time sensor data to optimize aerodynamic performance and ensure precise maneuvering at high speeds. Integrated with the DroneCore 1 flight computer, the software enables robust flight control, redundancy, and adaptability in varying flight conditions. Additionally, it facilitates telemetry logging and post-flight analysis, ensuring continuous performance improvements and safe, repeatable operations.
Vortex Lift
Weasel’s delta-wing design leverages vortex lift to enhance performance at low speeds, particularly during landing. As air flows over the sharp leading edges, it generates stable vortices that increase lift, allowing the aircraft to achieve it’s target landing speed. By utilizing vortex lift, Weasel balances high speed efficiency with improved low speed handling, ensuring stable and controlled touchdowns.
Take off / Recovery
Weasel uses a rail-guided launch system for stable, high-acceleration takeoff. It recovers via belly landing, eliminating the need for heavy landing gear, ensuring efficiency and reusability.
