Silly Invention: Useful or Not? Idea, "Heli-Submarine" Flying Submersible

[Tesla_WTC_Solution]

I don't know at all if this concept has been developed outside of the silly vertical takeoff and landing, and jet engine based craft... BUT... doesn't it seem like a Pontooned helicopter or something like that could be waterproofed, pressure-proofed inside and outside, and fitted with equipment that might allow it to submerge?

Or would it be too light to submerge? I don't understand those things too well and don't know if there is a propulsion system light enough to store aboard a helicopter.

I guess it could be very large to carry the extra weight.

Any thoughts on this poorly developed concept? LMAO!



Ideally this aircraft would first land on the surface of the water, fold in the airfoil/blades, then fill up the ballast and submerge.

Could it happen? Yes/No/Maybe/Why Not?


What inspired this? partially this pic (shown before but it's relevant to my dumb idea)

Sounds like an interesting engineering challenge. I see no fundamental reason why it would not be possible - that said I would not like to get into such a machine... A gyro-copter version may be fractionally more simple to design as the thrust engine for the gyro could also propel the sub, and the unpowered lift rotor may be a little easier to engineer to be submersion capable.

nature has them already, to a large degree.

No fair, yours can dive.
But in DUNE the birdlike craft were called Ornithopters.

Awesome! I'm still waiting for my flying car
(They did have a cool flying sub in Voyage to the Bottom of the Sea )
