<b>Community Starship Loads Model: Chapter 3 - LD0.1 Release!</b>
Hello again! I know I said last time I would wait until after Elon's next update, but I've been hard at work and I think we've got enough to cover for a major update. First of all, if you're behind and want a full re-cap, you can see my previous posts linked below. In short: I'm interested in studying Starship from a structural perspective. The first major project I'm doing in this realm is called a "Loads Model" which is basically a coarse Finite Element Model (FEM) with simplifications and optimizations made to the vehicle in an effort to balance complexity (bad) and accuracy (good). I'm doing this because I'm interested in it and I want to master the skill-set.Previous Posts: <a href="https://www.reddit.com/r/SpaceXLounge/comments/awy9t1/cslm_an_introduction_to_my_latest_project/">Chapter 1</a>, <a href="https://www.reddit.com/r/spacex/comments/cgmvxi/community_starship_loads_model_chapter_2/?utm_source=share&utm_medium=web2x">Chapter 2</a>.1 Modeling and Geometry1.1 GeometryI previously showed the OML. Since then I've created some basic internal structure. There are currently 3 basic types of parts included:Skins - Fuselage, Canards, Fins, and Tail. Each one has at least 1 property to change thickness as desired.Bulkhead - Personally, I make a minor distinction between bulkheads and domes. Both are oriented normal to the fuselage longitudinal direction (X-axis). Bulkheads serve the primary purpose of providing transverse support (fuselage bending).Domes - Domes serve the primary purpose of capping a pressure vessel, and have significant out-of-plane load.All of these objects can be seen in Fig 1 below.&#8203;<a href="https://i.redd.it/jl89cl92j9l31.png">Fig 1. Model Geometry Definition</a>I'll give each part a brief description here.Starting at the back, we have what I'm calling the Thrust Plate bulkhead or the thrust structure. As we've seen on the <a href="https://forum.nasaspaceflight.com/index.php?topic=47730.msg1979285#msg1979285">orbital prototypes</a>, this area is actually much more complex than a simple plate. So it will most likely need to be expanded in the near future. The base Thrust Plate is located at approximately X 48.28.Next up we have the Methane Dome or Lower Dome (I'm assuming Methane will be in the lower tank and LOX in the upper). The dome isn't perfectly spherical, and has an X radius of 3m, instead of 4.5m. The dome base (the largest section) is located at approximately X 44.45.Forward of the Lower dome we have the Common Dome. Same story here. Base is located at approximately X 35.50.Forward again, we have the LOX dome, or the Upper Dome. This dome is flipped from the previous two, but is otherwise the same. Base is located at approximately X 28.Next, is what I'm referring to as the Cargo Bulkhead. This represents the cutoff for "usable" space forward, and "working stuff" aft. X 24.14.Finally, we have the "Crane Bulkhead." This is located approximately where the crane and cargo doors will be (judging from the renders). X 13.21.Sidenote: In reality there will likely be additional rings periodically along the fuselage. This is especially the case at the leading and trailing edges of the canards/fins. I may try and add this in the future, after some more important updates. As we've seen in some of the prototype pictures, there are also a significant amount of stringers running axially along the fuselage to provide the appropriate stability and bending stiffness with thinner skins (read weight reduction). All in all, I expect the inside of most of the fuselage to look something <a href="https://cnet2.cbsistatic.com/img/mlBF8Lxs-Yw194YiovOvqM6aNeI=/936x527/2014/07/24/918d51c1-cb85-4974-8a43-6743189c2b81/fuselage-interior.jpg">like this</a>, but metallic.&#8203;1.2 MeshingNow that we've defined the geometry, I exported all of it, and "properly" meshed it for structural simulation. Overall, I'm pretty pleased with the model. Approximately…

Introduction to the r/SpaceX Community Awards
Introduction to the r/SpaceX Community AwardsThis is just a small meta post to let you know that we have recently added some new Awards as part of Reddit's Community Awards. These are supplementary to the awards we are all used to (Gold, Silver and Platinum) and you might have already seen them in other subreddits. Individual subreddits can have a number of unique custom awards, each with their own icon, specific to the subreddit topic.We introduced the following awards:Award nameCost to the userCoins to the communityFantastic Fly Back500100Informative Grid Fins500100Interesting Approach1000200Norminal Legs1000200Perfect Touchdown!2000400We also have a mod only award, called "Mission Success", that costs 1800 coins and is basically equivalent to the standard Platinum. We plan to use this award to give back to the the community the coins that the subreddit earns via community awards.Last but not least, big thanks to u/zlsa for providing the awards icons, really appreciated!

SpaceX FCC Filing - Starship Comms Supporting suborbital test out of Boca Chica
Quote from FCC filing: "This STA is necessary to authorize Starship suborbital test vehicle communications for SpaceX Mission 1569 from the Boca Chica launch pad, and the experimental recovery following the suborbital launch. Recovery is limited to 2 functions: (1) prelaunch checkout test of the TC uplink from the ground station at Boca Chica (less than five minutes in duration) and (2) experimental uplink testing from the ground station at Boca Chica during descent. Trajectory data will be provided directly to NTIA, USAF, and NASA. All downrange Earth stations are receive-only. Launch licensing authority is FAA Office of Commercial Space Transportation."Link: https://fcc.report/ELS/Space-Exploration-Technologies-Corp-SpaceX/1631-EX-ST-2019
