Objective: Design a next-generation speed drone built to challenge the Guinness World Record for the fastest drone.
Client: Drone Racing League (DRL)
Role: Senior Mechanical Engineer / Hardware Lead
Scope: Aerodynamic design, CFD, structural design, FEA, prototyping, and production planning
Tools: SolidWorks, SimScale CFD, FEA, Bambu Lab X1 Carbon (PA-CF, ASA)
Overview: DRL needed a drone platform fast enough to attempt a world speed record. Mechanical design and hardware development were led end to end, with the focus on the two parts that matter most at extreme speed: the canopy and the chassis.
Together they set the drone's aerodynamic drag, keep the electronics cool, and hold the structure rigid under full thrust, so each was designed, optimized, and validated as a system.
Aerodynamic Design & CFD
The canopy and arm junctions were refined through a series of CFD simulations in SimScale. The goal was to cut pressure drag while still pushing enough cooling air through the internal electronics bay, which houses the power distribution board, ESCs, and a high-density 5S LiPo battery pack.
Multiple canopy profiles and arm fairings were compared, and the best configurations reduced drag and improved stability at extreme speed. Every iteration was driven by a parametric SolidWorks model linked to the flow results, keeping the design process fully data-driven.
Structure & Materials
The modular chassis and canopy were designed in SolidWorks to balance strength, weight, and manufacturability. Prototypes were 3D printed on a Bambu Lab X1 Carbon in PA-CF (carbon-fiber-reinforced nylon) and ASA, chosen for heat resistance, impact strength, and stiffness-to-weight ratio, so the frame could handle both aerodynamic loads and heat from the motors and electronics.
FEA verified arm stiffness and canopy mount strength under aerodynamic and inertial loads. The final prototype was stiffer without adding mass, which is critical for thrust-to-weight ratio and high-speed stability.
Prototyping & Integration
The complete prototype cycle was managed in-house, from 3D printing and assembly to bench validation. Thermal and vibration isolation around the flight controller and PCBs kept signals stable at high motor speeds, and the internal layout was arranged for center-of-gravity balance, cooling airflow, and easy servicing.
Path to Production
The production plan moves the canopy to a thermoformed or injection-molded thermoplastic and the chassis to CNC-machined carbon fiber. These upgrades provide the repeatability, strength, and aerodynamic consistency needed across production units for official record attempts and standardized performance testing.
Results
Lower drag and better stability at top speed, validated in CFD
Stiffer chassis with no added mass, validated with FEA
A clear path to production in molded thermoplastic and CNC carbon fiber
