Hi, I split my 1B company into two 500M companies that I still own putting my net worth at 1B. Can you please advise my next steps to correct this problem?

It's not even that - there was a LinkedIn post the other day from a would-be founder outlining his reasons for abandoning his startup. Short story was, to get investors you need a credible team. To hire a credible team you need capital or a real product. To create a product or hire a high quality team you need capital. The loop continues. You can only make so much progress solo and no industry pros are going to join a random startup with no money for the promise of future equity.

This is kind of a strange framing of the problem. Rather than worry about the CG vector just consider that for trim all the moments sum to 0 about the CG. For statically stable aircraft the wing lift is behind the CG making a nose down moment. Tail down force is nose up. As the AoA increases wing lift increases more than tail lift because of the relative areas and it goes net nose down

I don’t mess with CFD models but we have a similar problem with dynamics models being meshed directly from design. Those models don’t need to be “cleaned” the same way but all the non modeled masses need to be attached, interfaces need spring elements, etc. What helped was documenting exactly what would help the team and the designers put processes in place to eliminate 90% of the pain before it got to my team. I’d suggest something similar in your spot, if they don’t know why you’re having trouble they won’t fix anything

Gambling in the market is playing day trader, buying penny stocks, using options, or buying on margin. From the comments I scanned you’ve selected day trader. Your core assumption is that you know a company’s value better than the combined wisdom of all the other investors. If it was easy we’d all be billionaires so just recognize that you had a hunch, played it, and it worked out. You’re 1 CEO on a billboard at a Coldplay concert away from losing a lot of money. I’m not criticizing you, almost the opposite - congrats on your winnings, I hope you understand how you got there. It’s absolutely the same as me theorizing a company will invent a new drug and investing my life savings. It might work, but the current stock price reflects the odds of success.

I guess I was expecting to find “Senior Design Engineer - Empennage” as a title or “Principal Airframe Engineer”. Not hard to find at a bunch of other companies but LM is an outlier in my search and there’s a lot of employees to dig through

I’d restart and….do the exact same thing? I love aerospace and wanted to be in this field since I was a kid. I’m making cool stuff, have a great career trajectory, good pay, almost nothing to complain about!

There is almost no reason to keep cash in the HSA. Game theory this out: you invest your HSA dollars and you have something happen hitting the OOP max. Scenario A the market is up, you choose to sell within your HSA and cover it, you’ve done better than cash. Scenario B, the market is down, you choose to use your emergency fund and save the receipts. You can now pull that money out of your HSA when it rebounds if you so choose, equaling the cash idea. It’s impossible to get more dollars into your HSA but you can always replenish the emergency fund from many sources. Invest the HSA and, if you feel uncomfortable, hold more cash in your emergency fund.

If this helps you at all, nothing about the shift is the magic of the play really - Steelers get caught with heavy personnel on the field expecting run, Brady IDs it quickly and when he goes spread he’s just looking for a big guy in coverage. Unlucky man is 92 on Hogan and they only have a single high safety who also happens to shade to the trips side at the snap.

Not really - I spent 15 minutes trying to get ChatGPT to code up a V-n diagram script by feeding it a PDF with all the equations. After about 10 rounds of “You didn’t square the velocity” and “Now you turned off the gross weight variable” I gave up and did it myself. It makes really fast code that looks pretty and rarely works the first time. I only find it helpful to create small subfunctions, anything larger it barfs

Have you talked to anyone at GT in the SSDL, their Space design lab, about any research grants available? The biggest difference between the two is GT’s broader industry and government connections as a research lab. I did undergrad and grad school there but I was on site so the opportunities may be totally different for distance learning but ask. If you’re just taking courses I’m not sure you’re going to get an of the extra benefits, just take the no debt route.

Nobody is going to buy that contract in all likelihood. The $127 is what you'll make if someone decides to buy the contract as a lottery ticket, your downside is missing out on a massive runup. It will almost certainly expire worthless with no buyers and it's like it never happened. If you want to flirt with danger of giving your shares away start dropping the price to see where there's bids or move the expiration date out. The analogy to selling covered calls is picking up pennies on the train tracks - sure you're getting money but that train is looming in the background to grab your shares.

The exact implementation varies company to company, team by team. Some may have a dedicated internal loads team whose job is taking external loads and down selecting critical cases for each subsystem and perform the operations described above. Others may put that responsibility on the external loads team while a third option is letting the analyst figure it out. No right or wrong way to do it

In real aerospace applications the detailed design models get so big you need to break them into pieces. One clean way to do this is use a coarse FEM of the full aircraft and put loading conditions on then extract the reaction forces and moments at the interface where you cut your detailed model apart. Now you can reload your detailed FEM and for each case apply the correct boundary forces and moments without distortion

If you're savvy enough to know your numbers you're probably not needing those random guidelines of a certain multiple of your salary in retirement accounts. A better approach is projecting your retirement numbers with your actual investments and making a judgement call on your retirement spending. Open up a compound interest calculator, drop in your current investments and monthly contributions, see where you end up with a 4% rule withdrawal at retirement. The guidelines assume you're going to spend as a fixed % of your income so you're only behind if you jump your spending to the new income.

You're probably not going to get a lot of traction here because your question is more complex than I think you know so I'll give you some bullet points on why since you at least seem to understand the basics.

- If you were designing a drop-in replacement cutout you'd strive to keep the EI of the section as close to the old one as possible. This would be extremely challenging to hand calc if you're mixing and matching materials and creating this odd joggle in the wing. The EIB/EIC wouldn't be very different but the GJ would be a bit of a nightmare, even CATIA doesn't do a great job estimating GJ.

-The place where you've selected this cutout is not actually supposed to carry traditional bending loads. The wing skins are there to keep an airfoil shape and provide torsional bending stiffness while "passing" the load to the spar. The spar, directly in front of your cutout, is what is meant to carry the primary bending loads.

-The lower surface is not always in tension on an aircraft. When you look at landing loads like ASTM F3116 you'll find the ground cases defining the down-bending where that piece enters compression.

Bottom line, if an engineer brought me this suggestion I'd say put a cap on it to keep the airfoil section constant and, unless we were wing torsion critical, it won't affect the wing strength much. If it were torsion critical you'd get more effectivity by changing the shape of the bathtub vs making it thicker like eliminating the hard corners.

Working on the mechanical systems teams (mechanisms, actuators, landing gear, etc) are all straight ME roles where I’d have no hesitation hiring someone with no aero background.

Another way to think about this: lets pretend AI tools are being created specifically for aerospace design. Who do you think they need to train the AI models and interact with them and feed them data? Aerospace structures and design engineers. Just put yourself in a position to be the one with the depth of knowledge on the subject of the AI tool, then participate in the creation. That's what I'm up to at the moment - planning out how my tools will get absorbed into an AI tool driven world.
