Design Off?

[kitflubber]

Oh, and it's called the U.S.S. Tom Cruise because most of it is hidden from the public (cymbal crash) Thanks you, thank you, I'll be here all week.

Well that makes my first design look somewhat conventional! How on earth can a carrier sub look conventional???

I've kept the outer dimensions of the Typhoon SSBN.


The cylindrical hanger is 10m in diameter and can stow 6 Yak-141 Freestyle fighters nose to tail.

The missiles under the ski-jump are 8 x SS-N-22 Sunburn ("Moskit") anti-ship missiles fired whilst surfaced.

The lift is outside of the pressure vessel at the rear. The door opens to one side and the aircraft lift comes up to hanger-floor level to receive the aircraft.

Not drawn are the two crew/engine hulls, the stores hull (smaller diameter below hanger hull) and the various CIWS and crew escape podes etc.

I've thought about Submerged/Surface warships for a while, I like Kitflubber's sketch of the semi-submarine...it would have a stealth sail, able to vent out, and have flash message capapbility easily.

 Can you imagine a fleet of these?  Battleships? Yikes.

  Love the Typhoon concept too...it seems to be built to be a carrier initially, with that wide profile. Genious.

WONDERFUL

Hey Kitflubber, that's pretty sweet!  What software did you use to render those drawings?  I'm sure a whole lot of us would love to know.

[kitflubber]

YSI_ Maniac, thanks!

SuperTom, it's Adobe Illustrator CS2 on Mac. I will do 3D when I can.

I have not done any of the needed work of scaling things properly (as Planeman obviously did) -- if we use VSTOL aircraft, ship may be smaller.

[Planeman]

Just a thought, but the Yak-141 is about 6m wide with wings folded. My hanger 'tube' is 10m in diameter, so in order to fit two Yak's side by side it'd have to be an unfeasible 14m wide.

but if I could design an equivilent fighter just 4m wide (or less) with wings folded I could fit two side by side in the Hanger tube, doubling my airwing.

So, mission ... to design a VTOL fighter that is just 4m wide when stowed.

Air wing would then be 8 fighters (4 rows of 2), about 6 helicopters including AEW and multi-role (ASW, ASuW,SAR).  

[Hobbes]

No need. Don't forget that the Yak is only 6m wide in the location of the wing, the remainder of the fuselage is narrower. You could probably park them in two staggered rows.

I sent Cthulhu77 a sketch for a carrier plane with lift fans (to be powered by bleed air) like the experimental 60's aircraft.

The I started thinking about a lift device that would not require extra engines, but be powered by bleed air, and not compromise the wing with a giant circular fan. So I devised this, a Squirrel Cage Lift Fan. Dont chuckle -- I am no aerodynamicist, but it seems like it could work:



The Squirrel Cage turbine runs a good portion of the wing root's length.

Kitflubber,

I don't believe your "Squirrel Cage turbine" would do much in that arrangement (nice pic though) - if anything, you would loose power/thrust with the turbine(not to mention the added weight).  Better to remove it altogether and simply go for an ejector thrust concept in that format (not that they've ever really been that effective in real life).

If you wanted a turbine using bleed air, you would be better of with an arrangement like that proposed with McDonnell Douglas's original JAST (fore-runner of JSF) contender which used a version of the F120-GE modified to allow high-pressure bleed air to be bled to the compressor and ducted forward to a turbine in the lift fan.

I love the Squirrel cage turbine but I fear that GTX's points are too close to the truth.

Re the Yak's width, I think the tailplanes would limit the practicality of staggering them. Here it is to scale compared to other carrier fighters with their wings folded:

[cthulhu77]

actually, with a little bit of manipulation, the exhaust thrust would work quite well out of KF's design...energy has to be relocated.  There is a a bias in some people's thinking about turboprop vs jets...Harriers are a prime example...horrible waste of fuel and energy.

  Fine tuning will result in something cool...I am sure.

  Re: the Sukhoi...they are really placing a lot of faith on those joints, folding that close to the chine edge.

...energy has to be relocated.

Usually into excess heat.

Re: the Sukhoi...they are really placing a lot of faith on those joints, folding that close to the chine edge.

But it seems to work:

[cthulhu77]

Yeah, but I kind of wonder how much they value the pilots? A fold at that much of a wing load joint seems rather "Petrov, Ve need ze space" rather than "Hey, let's make it safe".

  And yes, excess heat can easily be converted into lift.
