Breaking Through Thrust and Hydrodynamic Barriers
Overcoming the immense resistance of water, which is nearly 800 times denser than air, is one of the most significant challenges in underwater propulsion. Achieving the necessary thrust of 100 kg required innovative solutions and precise engineering. The team employed advanced hydrodynamic designs and custom-built components to address these obstacles. Key strategies included:
- Using 3D-printed materials to create propellers and housings with optimized shapes, making sure smoother water flow and reduced drag.
- Incorporating a triathlon wetsuit into the design to streamline the user’s profile, minimizing resistance and enhancing overall efficiency.
Despite these advancements, the dense aquatic environment continued to test the limits of the design, highlighting the need for further refinement in thrust generation and hydrodynamic performance.
Prioritizing Safety in Underwater Propulsion
Safety remains a cornerstone of high-performance underwater device design. The team implemented a range of critical safety features to protect users during operation, making sure reliability even in demanding conditions. Key safety measures included:
- A dead man’s switch and kill cord to instantly deactivate the device in emergencies, preventing accidents.
- Motor guards to shield users from potential injuries caused by rotating components.
- Thermal sensors to monitor propulsion system temperatures and prevent overheating.
However, safety challenges extended beyond mechanical safeguards. During testing, power surges in high-speed modes caused failures in custom PCBs, electronic speed controllers (ESCs), and battery management systems (BMS). These incidents underscored the importance of robust electronic designs and effective thermal management to ensure consistent performance and user safety in extreme underwater environments.

Balancing Power, Speed, and Efficiency
Power efficiency is a critical factor for underwater propulsion systems, where battery capacity is inherently limited. To address this, the team developed a custom throttle mechanism, allowing users to precisely control speed and power output based on their specific needs and environmental conditions. This innovation aimed to strike a balance between performance and energy conservation.
Despite these efforts, the jetpack’s top speed reached only 10.8 km/h in its highest mode, falling short of the shark-speed target. Interestingly, the scooter configuration demonstrated superior speed and stability compared to the jetpack mode. This finding suggests that while dual-mode designs offer versatility, further refinement is needed to optimize performance across both configurations. The insights gained from these tests will guide future iterations, focusing on enhancing speed and efficiency without compromising safety.
Testing, Iteration, and Lessons Learned
Extensive testing and iterative development were integral to evaluating the jetpack’s performance, safety, and reliability. Each phase of testing revealed critical areas for improvement, shaping the direction of future designs. Key takeaways from testing included:
- The need for more durable electronic components capable of withstanding high-speed and high-stress conditions.
- Enhanced cooling systems to effectively manage the heat generated by the propulsion system during prolonged use.
- Optimized designs for the scooter configuration, which consistently outperformed the jetpack mode in terms of speed and stability.
