This sounds like a perfect example of a Big Hairy Audacious Goal (BHAG), or what I've been calling a Big Heroic Audacious Project (BHAP) because I like the acrynonym better. "Don't Worry, BHAPpy"
The pirate community could choose this, or a similar audacious project, to try to win our grand prize at BillionHeroCampaign.com.
Even if you don't win the funding to Build the Ship, you would certainly raise awareness of it and all that it means.
I wrote about this here: https://steemit.com/bitshares/@stan/big-heroic-audacious-goals-bhags and plan to speak about it on Ernie's Phonix Rising radio show Wednesday, Aug 30, 2017 at 10pm EDT
Build the Ship!
-
Have been working on this since Ernie asked Larken to build a 3D model in Blender. I've finally gotten it to a point where it looks like something. Haven't done much of the detailing. The guns are pretty basic and I couldn't figure out how to integrate the windows into the 3D mesh. Detailing can go on forever, so I figure I'd better get some feedback on what I did right or wrong before trying to do more.
It's huge! I tried modeling to scale based on the drawing and its 1033' long, 1093' wide, and 386' high (231' to top of the deck). I think I remember hearing "100 feet tall". It this a cargo ship, or a starship?
I haven't applied any materials to the surfaces (other than to show glass vs. metal). What style should the ship follow?
1. Enterprise D - A clean, shiny, pride of the federation (state) with no defects (pretty much what it looks like now).
2. Nebuchannezzar / Millenium Falcon - A (dirty) rebel ship. Held together by it's "loving crew".
3. Serenity - Ridden hard, put away wet. Minimal maintenance. Nearly falling apart.
4. Reaver Ship - Falling apart. Held together with human entrails & items of conquest.
Of course the more detail, the longer it will take to finish.
I'm not sure what to do with the tail (it needs a lot of work). Can someone sketch up a detail of the stern? Is it a wall of thrusters like a Star Destroyer? Or a giant door like a C-130? Or bunch of docking bays for shuttles to land?
Also not sure how the sail works. Made it a grid of solar panels that collapse into the proper shape. Included a pic of them expanded, but I don't think it's practical to capture sunlight on a curved surface. Was thinking something that opened like a Chinese fan could pivot toward the sun (in any direction). Maybe origami solar panels?
Please give some feedback. I mostly used the detail sketch to build from (thanks for making it). But once it was taking shape it looked a little different than Scott's final rendering. The wings look a little "fat", but could be useful if the ship is mainly for transporting cargo.

Wow!
These are great. I've been hoping to have a 3d model to print.
Nice work!

Thanks. I'm sure there will be a 3D printable version in the future. I'll need help figuring out how to prep it for a specific printer/technology, and if it should be all one piece, or something you put together (separate engine pieces, solar panels, etc.).
Made a rendering of the wings collapsed for "hypersonic mode" (and fixed an issue with the solar panels).

Wow! Cameron,
We've been very busy and are only checking in more (after the publishing of the 3rd Letter of Captain Marque we'll be spending more time on the Forum).
Lots of back end stuff being done and the art you've created is very very cool and just what we were hoping for. Thank you very much.
I have a request. We need to know the air displacement of the shell. This volume will determine how much it will lift. We'll need to measure the helium/hydrogen air bag volume needed to lift the craft without thrust if possible. The airfoil still needs to be maintained so that capacity is increased with forward thrust/lift.
Big step forward.
I hope you'll come on the radio show to talk about the work you've done.
Peace,
Ernie

It'll probably have to be multiple pieces, since there's no real flat surface.
I don't think that it should necessarily be a design consideration in blender that it will be 3D printed, we can break up the model afterwards.
There are 3D printer types that would be able to print it with less regard to the shape too, such as "powder bed" ( https://en.wikipedia.org/wiki/Powder_bed_and_inkjet_head_3D_printing )

Hi Ernie. I'm still listening to yesterday's archive. I'm glad you like it.
For cubic volume, I used the main "body" (without the movable wings, engines, "skull", or the tail).
[attachment=0]p13.jpg[/attachment]
At its current size, it calculates to 39,309,656 cu.ft. If you chop off the wings (fuselage only), it drops to 23,256,222 cu.ft.
Do airfoil's work at that scale? The wings are over 600' long. I'm not an engineer, but imagine you'd need extreme air flow to get lift from something that large.
I'm sure I'll be too nervous to be useful on the show. I'm very quiet (100% introvert). I'm the complete opposite of you on your show. But if you like, we can try an aftershow, or something where I don't have to worry about sounding horrible.
Thanks.

Question
What is the weight of 1 cubic foot of air?
Asked by: Jonathan
Answer
FINAL ANSWER: 1 cubic foot of air at standard temperature and pressure assuming average composition weighs approximately 0.0807 lbs.
-
Helium is less dense than air. Helium has 0.0114 pounds per cubic foot
Hydrogen lifts 68 lbs per 1,000 cubic feet [1], thus ~14.71 cu. ft. per lb
The weight of standard air is 1.2256 Kg/ Cubic Meter.
The weight of hydrogen is 0.0857 Kg/ Cubic Meter. = https://www.unitjuggler.com/convert-volume-from-cuft-to-m3.html =
Conversion base : 1 ft3 = 0.028316846592 m3 Conversion base : 1 m3 = 35.314666721489 ft3
.0857x.028316846592=0.002426754
Sooo I guess
Hydrogen is 0.002426754 per cubic foot (I'd check this. that's a lot lighter than Helium.
Hydrogen would be an interesting choice since the solar panels can crack water into Hydrogen that can be stored for rocket fuel, along with the Oxygen, and for the bags.
Maybe not "with" the oxygen :)
If you do some of this calculations with as much space as you can use for bags then we'll know what thrust/lift we need and how much weight in material we will get to use
Such as:
23,256,222 cu.ft of the trimmed down ship may need 2/3rds of the space for cargo and people space etc.
So say 8,000,000 Cu.ft. that's
645600 lbs. of air that will be replaced with
19414 lbs of Hydrogen or
91200 lbs of Helium
So that means that we get to use 626186 lbs of structure to make the craft float without any lift or thrust..... interesting.
This is "Napkin Math" and I'd check it. But it gives you an idea. It also explains why you need to have as much air displacement as possible and still keep a lifting shape. But coolness is a factor as well. I like your work.
When you get further along and are able to place where the bags will go then we can start working on the gas vs. open spaces and what thrust we need for Vertical takeoff. Then the aerodynamics of the wing for its lift at what seeds... blah blah blah.
Your work on the displacement just got us a lot further along. Thank you!
After you have time to play with this then we can do some math.
If you ever check these numbers and are comfortable putting together some illustrations with these facts, let me know and we'll put something together for the forum OR you can just start posting these calcs up now and get more people helping with such stuff.
Peace,
Ernie

This suggests that the calcs I did comparing Helium to Hydrogen were wrong, I hope you get the idea.
The Relative Lifting Ability of Hydrogen and Helium
Although helium weighs twice as much hydrogen, because each gas is so much lighter than air helium provides about 93% of hydrogen’s lift at full purity. In practical operation it is impossible to achieve or maintain 100% purity of either gas, reducing helium’s lifting ability to about 88% of the lift of hydrogen.
The actual lifting ability of each gas varies with temperature, pressure, and humidity, and to take account of varying atmospheric conditions and gas impurities airship designers often conservatively estimated helium’s lift at 60 lbs per 1,000 cubic feet and hydrogen’s lift at 68 lbs per 1,000 cubic feet.
Relative lifting ability of 100% Hydrogen vs. Helium
60° F, Barometric Pressure 29.92″ Hg
Weight of Lifting Gas
(per 1,000 cu. ft.) Weight of Air
(per 1,000 cu. ft.) Net Lift
(per 1,000 cu. ft.)
Hydrogen 5.31 lbs 76.36 lbs 71.05 lbs
Helium 10.54 lbs 76.36 lbs 65.82 lbs
The Effect of Helium on Airship Range and Payload
In actual use, because of physical realities and operational considerations, the use of helium can reduce an airship’s payload lift by almost half.

I was reading the same page a few days ago!
Found the same 68lbs/1000cu.ft. That means 1300 tons for the 39 million cu.ft. volume. Did you read the comments about recompressing helium instead of venting it? http://www.airships.net/helium-hydrogen-airships/#comment-589500
I will email Donna today.

I'll include some private posts data we have been discussing while checking our math etc since there is some useful links, measurement and concepts.
The 'Social Subsystems' are of little interest to me right now. The Precariat will be the private property of Captain Marque and he can do, whatever he wants with it. Build it and they will come applies to additional ALT-Ships with their own 'Pirate Code'.
It's the tech that allows for the ship that is disruptive. What someone does with their Liberty and Property is of little interest to me as long as they leave me, my friends, family and customers alone.
So, I wish to focus on the tech.
Subsystems to me are systems that influence things like, Buoyancy, thrust, communications, navigation, power, life support, security & defense, entertainment, food, water, maintenance etc.
Other systems like Gravity, tractor beams, Warp/Quantum drives (CrossBoneDrive - we already have a back story and graphic ideas :) can be incorporated in the design, but not at the risk of usable tech being detailed. Anyone of you that have spent some time on the net looking for advances in these areas and Airships in general see that we are farther than I think most of us realize.
Scan the Tech listed on the "BuildTheShip" category and you'll see what I mean http://pirateswithoutborders.com/buildtheship.
The other categories are just as full of ideas to place in the ship for most if not all of the other systems.

But you have the blender pieces to start something ... Now all the new intel and AMD chips are posting Blender specs... Now it sounds to me like your thinking this is a Cody 3d software thing.. Much more powerful than that.. What you have is Pixar in a box.... Big ideas.... need to story board. 20,000 leagues under the sea thought as opposed to an applied math problem...
There is some interesting youtube classes on blender and you might think about a github to share off pieces......... Tarantino stole reservoir dogs and my thought on Blender was Doctor Seuss Butter battle book ... or sure you know the some books that could be extended to this .. Not the software for 3d printing.... my youngest is Making and characterizing PC-board based microwave circuits for picking up photons on Quantum computer... temperature constraints and squirrely stuff... so blender visualizations.. Yup gave him same lecture you gave your kids about airplanes fighter jets or jest and whole deal.... Get in touch with me and can yack it up... It is the message I think...

Created the pink 1,000 cu.ft. "balloons" and changed the body to a carbon fiber mesh. Maintained metal for the leading edge of the wing, the (future) flaps, and the enclosed living space.

Still working on the detachable cargo module, merlin engines, flaps, ion drive, hover craft, & flat solar panels before making the website graphics. I also have ideas to redesign the archway/lift platform to make space more usable without impacting the lift envelope.
-
Nice adaptation of the Mesh to contain an "envelope" for the Lifting Gas.
This is just an option and there are many ways we may contain the Lifting Gas (Sealed Shell, Envelopes inside Shell, variations on the theme you've detailed etc)
This is a nice way to greatly reduce weight though.
Great work
-
Rotation of the outside Ducted Fans has too much drag with the remnant of the wigs attached to the Fan Housing.
Making them more Ball shaped will allow them to rotate inside the wing tips more with a mount much like the ones you've used on the head area. This is something to worry about later as you continue to develop.
I saw the floor plans on the Subsystems page. NICE!
Soon I'll spend some time on the engineering of the infrastructure and try to get some material weights etc.
Thanks
-
Will work on removing the drag causing surfaces. Had difficulty originally figuring out how the engines attach. The wing can tilt 18 degrees. So the engine has to counter tilt the same angle to maintain level. Figured an X-axis "hinge" (front to back) would cover this.
[attachment=1]p21.jpg[/attachment]
Then the whole thing can rotate up to 360 degrees on the Y axis (left to right).
[attachment=0]p22.gif[/attachment]
Having a hard time imagining how this connection would mechanically work and if the torque generated by the engine would damage this connection. Some kind of universal joint?
Will take another stab at it, but it will likely change if/when someone can come up with the best mechanical & structural joint.
-
Much work is being done with developing a 'solar paint' that I believe will eliminate the need for 'panels'. The entire surface of the ship can be coated so that any area facing light will collect/convert it to energy.
There is also being developed lightweight cells embedded into thin plastic that can be unrolled like sheets of streamers below the ship to recharge batteries much quicker when necessary, then retracted back up into the ship.
One more mention.
When a Space Shuttle was working with a 'tethered object' that it was lowering into the atmosphere they found out that somehow electricity was being harnessed in the process and it fried out a bunch of stuff. Is it possible that this phenomena can be used...?

Thanks again EB! I had forgotten about the tether experiment (https://www-istp.gsfc.nasa.gov/Education/wtether.html). It sounds like it could also raise the orbit of the ship. Definitely something to research more.
I'm also interested in a "solar fabric" that could be lighter than standard solar panels. The ship is currently so huge, the solar array (as drawn) covers 20 acres!
-
Finally completed the next changes for the ship. I'm calling this "version 3" of the Precariat.
- Made the cargo hold detachable.
- Added flaps, elevators, & rudders.
- Added ion-drives to the wing & tail edges.
- Added 27 merlin engines to the stern (equivalent to a falcon heavy).
- Removed the drag surfaces from the main fans.
- Re-shaped the hull where the front fans used to be.
- Re-shaped the "chin" to give more interior space & access to the cargo hold.
- Re-shaped the stern (the original mesh was a mess)
- Added a freight elevator & turbo lift that spans the 15 floors of living space.
- All this affected the lift envelope, windows, & mesh containment (had to re-work those too).
Here are a bunch of new pictures.
Also posted transparent png images of the ship at http://precariat.us.to/graphics You can also donate crypto on that site to support my work.

To lift a craft this size and magnitude without thrust would require not only enough lift from the gasbags but the other component that, after a quick search of this Forum, only I, Eduardo Blomar, has mentioned;
Water is eight pounds per gallon and requires 231 cubic inches of space to contain (as with most liquids).
Additional inquiries include:
What powers the turbines? If electricity, is the energy storage battery? What type? Where is the Battery Deck located?
Much work has been done in the field of rotating heavy cylinders (counterweights?) at high RPM's and leaching off the energy (turbines?).
Why are the wings not covered in solar cells?
Will there be any inclusion of space for a
I have many more, but for now, that will suffice.

Hi EB,
I've thought about stability (i.e. the ship becoming top heavy and flipping over). The cargo is more than enough to lower the center of gravity so it will always be right side up (as long as you have cargo). I also thought about adding water tanks just above the cargo, or near the tail (in engineering) to balance out the weight distribution. The belly of the ship (just above the cargo hold) is 45K+ sq.ft. a 1 ft. deep tank would hold 342K gallons (or 1300+ tons) of water (more than the ship can lift). There is plenty of space to pump water around if necessary.
I still have concerns that the ship is just too big,
As far as ballast for jettisoning. There was a hint of that topic discussing
I believe the idea is that the ship will be electric. The turbines are huge (I think 80'-100' diameter). Not sure if those will work, or will be replaced with many smaller versions to add redundancy (and not have a 90' fan blade : )
Energy storage could be achieved by batteries, splitting H2O (then recombining when needed), or your spinning flywheel idea (thanks). Though flywheels and batteries are very heavy, so I don't know if they would be preferred (it's not up to me).
Collecting water from the air and splitting into hydrogen & oxygen seems like pretty cool way to store energy (even if it's not efficient). If the ship really gets 20 acres of solar panels, you would have more energy than you'd need (and not worry about efficiency).
I'm not sure how the Merlin engines would work. I suppose you can generate your own liquid oxygen, but would still need to carry & store kerosene/rocket fuel. Maybe they can be upgraded to hydrogen engines like
Still trying to think about the solar panels. The existing setup isn't very flexible (no pun intended). They can only be deployed in space and don't move to track the sun. Someone would have to study the feasibility of covering the entire ship in solar panels (including the wings). Currently the most efficiency comes from pointing directly at the sun. Orienting the ship to always be perpendicular to the sun would be much less practical than unfolding a "sail" that can pivot in any direction.
A "flight deck" could be on top of the ship. Possibly at the front where the big gun is located (currently just for looks). That turret is almost 60' diameter. The upper deck is over 65K sq.ft.

Have been working on an animation of the Precariat. Added a level 5 window, and a rear window to engineering (which may become something else). Here's the clip of a "quick assembly", virtual tour, and flight put to obscure but inspiring 70's music.
You can view the animation here... http://precariat.us.to/animation
As always...

hello ernest i was woondering if youd like to do a virtual interview i run a liberty group on my college campus and just watched your interview with the guy from the understanding our slavery book. its what brought me to these forums!!

After two years, I realized the ship has sea-level bell nozzles and not the vacuum optimized ones (9-10x larger). Changed the Merlin engines to have the larger nozzles.
27 total. 17 on the rear + 10 on the ducted fans.
