| It's interesting how simple this looks, off the shelf parts, and 3D printed components. I'm almost surprised this doesn't already exist after looking at it. |

| ▲ | engineer_22 5 hours ago | parent [-] | | If your mothership is low-observable/submersible you could park it in a harbor and when time is right unleash a swarm of hybrid aerial underwater drones with mission payload. This design uses 1 swashplate server plus 1 brushless drive motor for each prop for a total of 8 motors. Designs in Ukraine are now using 1 brushless drive motor to synchronously drive all 4 props and 1 swashplate servo each prop, reducing total number of motors to 5, which might be a natural path of optimization for this type of hybrid aerial underwater? | | |

| I feel like I've seen some of these before without the variable pitch part ex. https://www.youtube.com/watch?v=jlMDabBfJp0 |

| If this what can be done with off the shelf parts and 3D printing, imagine what DARPA and the like have been doing for the past 20 years. Makes the UFO/UAP stories about "it transitioned from the water to the air and back to the water!!" seem way more plausible. |

People always say this, but anyone I know who's ever worked in one of these companies that contracts for the DoD or DARPA always complains about how behind the market government tech is. Obviously private industry isn't producing competitors to the F35, but for less complicated kit the government doesn't seem to be doing anything super sophisticated. In fact a bunch of people I knew who went to Iraq bought supplemental gear on the private market. | | |
