Submersible aircraft

[Jemiba]

"The Commander looks kinda like this guy:"

.. and this is probably exactly the kind of aircraft, Reid has demanded a
licence fee for !

Thanks Jemiba, you made my day! I had only one low-quality photo of RFS posted in reply no.2 so now I can see the shape of the rear fuselage.

I've scanned in and made availabe “Proposed Study of a Flying Submersible ASW Vehicle,” General Dynamics/Convair report HP-62-016, from 1962. This is, so far as I am aware, the only real documentation out there (not counting a few articles and a couple drawings) about Convairs flying submarine. Or submersible airplane. Whichever it is...

And what about a submersible  Polaris-launcher seaplane with four  Phoenixes and two Subrocs for self defense? In a word, the Petrel. The two Polaris are in the two large tubes amidship. They can be launched via extraction by a parachute, both submerged and flying. The Phoenixes are in flush compartments two per side, the Subrocs are in tubes under the nose. The concept was presented by two Virginia Tech guys at the 12th AIAA Annual Meeting and Technical Display in 1976.

Interesting concept, looks like a scaled down P6M Seamaster. How serious was
it ? Launching the Polaris may have been ok, just launching the Phoenix and Subroc, too,
but squeezing the avionics especially for the last two weapons systems into this aircraft,
may have been a very hard task, I think. And the whole thing submersible !

Not at all, actually. it was a project by a few college students. Got them their grade and presumably their degrees, but it was not a serious industry effort.

Scott has it right, naturally...

I've seen a concept of this in the movie "Sky Captain and the World of Tomorrow". Pretty cool!

Me and my friend are comming up with our own designs for submersible helicopters. has anyone else come up with designs like these?

[Michel Van]

So far i know no

if was Project like this only with Retractable propellers.

Helicopter propellers dont work in underwater
water is 800 x dencer as Air ...

He he....that´s why I like "The Thunderbirds"...

I found the Dassault Trifibium (that's my drawing from the artwork)

Hi All, my first post here 

This scan is from April 1992 issue of an now defunct Yugoslav Science magazine, Galaksija.

According to article, top speed was 600 km/h.

The plane lands like normal hydroplane. After that, four hatches are closed to protect the two turboreactors. The wings are contracted like scissors and two hydrojets take the control, powering the plane up to 20km/h.

The plane has a 8*2 watertight compartment for 12 passengers. In case of engine failure, the craft ejects the water from the tanks and surfaces.

This was the project of an student of industrial design (the name is not mentioned) with assistance of CNRS engineers. Dassault Aviation sponsored the project.

Thank you very much !!!!!! and welcome here

I've looking for that info for years

[hole in the ground]

lol, i have always loved the idea of sumbmersible aircraft... but never understood the reasoning for why
But the sticking point in my mind has always been that aircraft are designed to keep pressure in, submarines pressure out. Aircraft are designed to be lightwieght and subs heavily constructed to take the pressures of being submerged.
Seems like the compromises would be crippling to any design...

Why do I seem to fixate on the word april?
