I’m developing a hydrogen fuel-cell drone dedicated to long-range surveillance across mixed terrain, and I need an expert who can take the concept from rough outline to flight-ready platform. The aircraft must stay aloft far longer than standard Li-ion multirotors, carry an optical payload suited to detailed observation at distance, and handle transitions between open rural zones and cluttered urban fringes without losing signal or stability. I already know the broad performance targets— extended endurance, silent operation, and a minimum control radius matching typical BVLOS requirements— but I’m looking for someone who can translate those targets into concrete engineering decisions. You will be responsible for: • Selecting and sizing the hydrogen fuel cell, storage tanks, and balance-of-plant components, showing how they meet the energy and weight budget. • Designing or adapting an airframe that maximises lift-to-drag while housing the powertrain safely. • Integrating a gimbal-stabilised camera system that supports crisp long-range observation, with provisions for future thermal or multi-spectral sensors. • Detailing avionics, flight controller (Pixhawk/Ardupilot or comparable), telemetry links, and ground-station workflow that remain stable over mixed terrain. • Providing CAD files, wiring diagrams, and a verified bill of materials along with performance simulations (SolidWorks Flow/CFD, MATLAB, or similar) that demonstrate flight time and range. • Recommending a test plan; remote witnessing of first flights is fine if you have a proven setup. Acceptance criteria 1. Simulated endurance under specified payload matches or exceeds the benchmark we set at project start. 2. Structural analysis confirms safety factors for composite arms, fuselage, and tank mounting. 3. All documentation is complete and reproducible by a third-party builder. If you’ve already worked on hydrogen UAVs, fuel-cell integration, or BVLOS surveillance platforms, please mention specific examples and any flight hours achieved. I’m happy to iterate quickly, provide feedback on sketches, and schedule video calls to keep momentum high.

Hi there, The key challenge here is achieving the required endurance while keeping the hydrogen system, payload, airframe and structural margins within a realistic weight budget. I can support the engineering side with airframe/CAD development, structural FEA of composite arms, fuselage and tank mounts, CFD/flow analysis, load-case definition, and performance/weight-budget evaluation. I can also prepare detailed engineering documentation, BOM and simulation results suitable for third-party build and verification. My background includes FEA, CFD, mechanical design, engineering calculations and 3D CAD, with experience taking engineering problems from concept through analysis and documentation. Could you share the target take-off mass, payload mass, required endurance and hydrogen storage capacity so I can assess the feasibility and propose the initial configuration? Timeline and budget can be finalized after discussing the complete scope. Best Regards, Arati

Ethan here, from South Africa. Your project immediately caught my eye. I'm really excited to partner with you. I understand you're developing a hydrogen fuel-cell drone for long-range surveillance across varied terrains, focusing on extended endurance and maintaining signal stability. My approach would involve selecting the appropriate hydrogen fuel cell and tanks while ensuring they fit within your energy and weight budget. I would then design an airframe that maximizes lift-to-drag, accommodating safe housing for the powertrain. To ensure a high standard, I will provide detailed CAD files, wiring diagrams, and performance simulations to validate flight time and range. I believe it’s crucial to not only complete the tasks listed but also deliver a reliable platform that meets your overall performance targets. Please feel free to reach out so we can connect and further explore how I can contribute to your project's success. Kind regards, Ethan

Hi, Your project is interesting because the real challenge here is not simply designing a drone—it is balancing endurance, payload, hydrogen energy storage, aerodynamics, structural safety, and reliable avionics. into one practical aircraft. I can help develop the platform from the initial requirements through the engineering design and documentation. I would begin by converting your endurance, payload, range, and operating requirements into an overall weight and energy budget. From there, the fuel-cell system, hydrogen storage, propulsion, airframe, camera payload, avionics, and communications can be sized around the same set of constraints. For the airframe, I would focus on achieving efficient lift-to-drag performance while providing safe and practical mounting for the hydrogen system and electronics. I would also account for structural loads and verify critical components through appropriate analysis. For the power and avionics side, I can work through the fuel-cell/battery/supercapacitor architecture, flight controller integration, telemetry, sensors, power distribution, and payload interfaces. The gimbal camera can also be incorporated with provisions for future thermal or multispectral payloads. I can provide the supporting CAD, wiring documentation, BOM, and simulation results needed to make the design reproducible and easier to prototype. Best regards, Oluwasogo
