Ok let's do some math: . Going off the forging marks, the proportions, and the black oxide coating, we can reasonably assume that the lifting eyes are McMaster PN 2994T42. Based on this we'll establish a scaling factor of 1.85/1.5=1.23

I don't think this setup actually achieved fusion and here's why:. Starting with the vacuum pump It seems to be this model from Amazon which claims to be capable of reaching an ultimate pressure of 2E-3 Torr. I think this is an extremely optimistic rating.
over a 36-hour livestream, I built a neutron-producing nuclear fusor in my kitchen using Claude. successfully achieving nuclear fusion, entirely assisted by AI. this was my first hardware project!—full story below

Yes, I'm sure V3 throttles down to 40% (assuming same range as V2) using no valves or electronics.
This engine is the greatest rocket engine ever built, BECAUSE they got rid of all the electronics and software. Fluid management system? Nope. The shape of the pipes is the fluid management. All of Mech Eng is full of similar opportunities.

- I cofounded the original Aphelion.- I designed our suborbital rocket but did some on orbital development too.- Did all the solid motor and structures development.- Our COO was embezzling money and eventually stole all our IP, logo, CAD, renders, etc and started another company.
A hypergolic commercial rocket?!?!? With an aerospike?!?!?!?!? (company is aphelion orbitals)

I love when I need to make small changes, but I don't have a constrained model so instead I get to argue with fucking cleverbot to make the smallest changes until eventually the model is hallucinating so hard that you ask it for a raspberry pi case and it gives you a glock frame.

I feel like if you have to take an ethics course to know not to do this kinda shit you maybe should just not be an engineer in the first place.
Location of a debris field by USCG is the latest grim development in this Oceangate story that is sure to be a cautionary tale in engineering classrooms for decades. Engineering ethics is the most important component of any engineering curriculum

Let's take a moment to appreciate that two absolute madmen in 1958 and 59 managed to keep a Cessna 172 in the air for 64 straight days. They took shifts sleeping and flying, and refueled by flying low and dragging a fuel line up from a truck as well as food and supplies.

maybe because software engineers (an extremely liberal use of the word engineer) take every opportunity to tell us how to do our jobs and constantly act like we're too retarded to actually know what we want or need so we must rely on their god-like intellect as a guiding light.
@robirwinengr Yes ofcourse - but maybe the hardware folks are way too jaded? There’s a YC company making text to cad and all the old timers are hating on it like it’s a scam.

No, the dozens of lawyers that SpaceX pays thousands of dollars an hour failed to realize that a large contingent of government officials including the president elect of the United States were coming to visit until an hour before and then were just like "eh it's probably fine".

So, given:.- Ae/At=110.- De = 36" .- Pamb = 0 psi (vacuum engine).- O/F = 3.6 (fairly standard for methalox).- %CL = 88 (as measured in CAD).- T = 15,000 lbf (official spec). We arrive at a chamber pressure of 810 psi, 18.4 kg/s total mass flow rate, and 369s of ISP in a vacuum.

Given this scaling factor, we can assume an exit outer diameter of 20.42*1.23=25.11". However, given the large exit wall angle and the finish machining, as well as current renders, a nozzle extension is likely yet to be fitted.

Based on these criteria we arrive at these numbers:.- Ox preburner O/F = 42.- Ox preburner fuel mdot = 0.35 kg/s.- Turbine pressure ratio = 1.09.- Turbine temperature drop = 19 K.- Turbine pressure drop = 87 PSI.- Ox preburner mdot = 14.75 kg/s.

223
Now let's establish some pressure drops from the chamber backwards:.- Main injector = 20%.- Ox preburner/turbine = 25%.- Line losses = 5% . Given the 810 psi chamber pressure, that gives us a pump discharge pressure of 1421 psi

Think about it this way: every computer or engine is filled with "impressive" and "complex" arrangements of material, most of them far more elaborate than any marble statue. This is impressive, and even aesthetically pleasing, but it does not make them works of art.

Given the measurements at the throat and the exit, as well as current renders on their website, we can assume the total expansion ratio to be about 110, and exit diameter of about 36"

While this appears to be within the desirable range for a neutron-producing fusor, you actually want to shoot for a vacuum in the range of 10E-4 to 10E-5 Torr and then backfill the chamber with Deuterium to the 10E-2 to 10E-3 Torr.

While this is a very cool project, based on the points I outlined above, I do not believe fusion was achieved and neutrons produced.
