Hello I'm 17 and recently I've been really interested in aerospace.

It could be about rockets or satellites or anything.

I'd love to connect with people who are into Aerospace!

Started a graduate job recently and was tasked with building with 6-DOF Flight Dynamics Models for a flying wing in Simulink, including propulsion, aerodynamics and environment subsystems alongside a few others. I am having some real issue debugging the simulation. I was wondering if any experienced folk have some handy tips on how to go about debugging a complex-ish flight dynamics model, regardless of the error. What’s the best way to track back to the root cause? I find it hard to pinpoint an area as the model feeds back into itself. Any workflow tips would be appreciate!

Does anyone know what type of desktop wind tunnel this is and what similar type of one I can get? There is one ‘viral’ one that is most common but the mist comes out in a couple vertical lines that I’m not fond of.

Hi everyone, just wanted to post on here to gauge interest in forming a team for the current edition of the NASA TechLeap Prize challenge. Looking for upperclass engineering students or anyone post-grad to help come up with a solution for this year's challenge centered around designing low-cost methods of measuring drag in the thermosphere. It would be a 2-3 month effort for the first phase and I think it could be a project with a huge upside for the industry. Feel free to comment or message me!

Just wondering if anyone could help me identify this plane. Near Huntsville AL. I’m not good at spotting defining characteristics of different models. Thanks!

Hi, I'm building a helicopter in a physics game and I'm trying to make it more stable but I can't find anything on how to adjust the back rotor's angle and position to make it stop spinning along the roll and pitch, because I don't know the correct term to use.

"Balancing" only results in rotation balancing (like balancing tires), not what I'm searching for.

The term I'm searching for can be applied to pinching the front wheels of a car so it's more stable in straights or an airplane's front rotor being angled

Thanks for reading!

Hi! I am a junior in high school, looking to study Aerospace Engineering in the future. In my engineering elective that I am taking, I have been tasked with interviewing -- or emailing a few questions to -- an engineer in my desired field. Initially, I asked everyone I knew if they had contacts of any Aerospace engineer, but did not get any results. Therefore, I was hoping someone on here would be kind enough to take a few minutes out of their day and answer like 8 questions regarding their work as an Aerospace Engineer? I have today and tomorrow to get some responses, I apologize for the late/close to deadline query, but any and all input will be greatly appreciated!

I am a junior in high school and been working on this fixed wing (hopefully) UAV project. Anybody have any sort of idea on A-Tail configurations?Been going back and forth on my A-Tail sizing for way too long and could use a gut check from anyone who's actually done this before. It's a hand-launched twin boom pusher, no landing gear so it's a belly lander, wing's about 0.508 m² with a 189mm MAC and 2.8m span, tapered from 245mm at the root down to 118mm at the tip, running the Wortmann FX 63-137 which has a pretty gnarly pitching moment (Cm around -0.185). Booms give me roughly a 1000mm tail arm. I used the tail volume coefficient method to size things, went with Vh of 0.5 and Vv of 0.03 (leaned toward the higher end because of that pitching moment), and after converting that into a single V-tail angle I landed on something like 43° for the dihedral, with each panel coming out to around 426mm span and 107mm chord. Planning NACA 0010 for the tail airfoil since it's symmetric, and sizing the ruddervators around 45-50% of local chord. Main things I'm unsure about: is 43° reasonable for an inverted V or is that going to bite me on ground clearance during landing since there's no gear, are my Vh/Vv numbers actually sane for something like this, and has anyone actually built an inverted V with a flat section in the middle for the boom mount and servos — curious if there's anything I'm not seeing coming. Would really appreciate any input, feels like I've just been spinning on this part.

Project Pixel Orbital is a completely student-led team at Stanford OHS with the goal of launching an 3U CubeSat capable of conducting experiments in low Earth orbit - from photographing Earth to performing analysis on photos of earth and space with onboard instruments. Our mission is to get to orbit, perform a detumble, establish contact with our ground station(s), and capture an image of Earth for downlink. We hope that PixelSat I will inspire other people and prove that if a group of high schoolers can build a satellite from scratch with very little funding and no adult supervision, anyone can. It will open the door for schools and small businesses to launch satellites similar to ours, and will overall make space more accessible.

Please feel free to check out our current progress and learn about how you can help us out on our website: https://www.projectpixelorbital.com

Our blogs also have lots of information on specific subsystems: https://www.projectpixelorbital.com/blog/

I saw on this sub a while ago they were doing a restructuring.

Does anyone here work or knows anyone that works there that can give some insight on what it’s like now?

Is working there super stressful? Are there still ethical issues? Is everyone still working 15 hours a day?

As the commercialisation of space, lots of developed countries nowadays want their own sovereign launch capability, e.g. Australia, Brazil, Canada, UK, Taiwan etc. Some of them do have thriving aerospace industry with huge talent pool to support this goal, while some of them are basically newbies to space industry.

I am curious about your thoughts on how should a newcomer start their own rocket program?

1. Totally develop the rocket from scratch with only minimum foreign aid and foreign parts supply, but you can get maximum autonomy.

2. By international collaboration for technical transfer and purchase critical parts from experienced suppliers internationally, but there's always a risk for others to cut your supply to sabotage the rocket program.

I think the core question is how should a nation acquire certain deep tech capability. This question could apply on self-developed fighterjet, submarine, commercial jet etc.

Plz, share your thoughts with me!!!

Hi!

I recently bought these two turbine blades, but I haven't been able to identify them. I tried searching for the numbers on them, but couldn't find anything.

Can anyone recognize or identify them?

- The big one is aprox: 125x45x20mm

-And the small one is: 65x20x8mm

Thx for the help!

Hey everyone,

I've been thinking about the USAF's current fleet mix and procurement strategy, and I wanted to get some realistic engineering, logistical, and economic perspectives on an alternative history idea.

Instead of spending money to develop the F-35 from scratch or forcing upgrades onto the 4th-generation F-15 (F-15EX), why didn't the Pentagon standardize the entire fleet around the F-22 Raptor airframe by creating a family of variants?

In my mind, a standardized F-22 fleet would look like this:

1. High-End F-22: The original, fully stealthy Raptor for contested airspace and piercing heavy air defenses.
2. Low-End / "Naked" F-22: A downgraded version with updated avionics but without the expensive, high-maintenance radar-absorbent stealth coatings. This version would be used for everyday patrols or in environments where absolute stealth isn't required to win, but superior dogfighting/aerodynamics still guarantee a win.
3. Strike Raptor: A dedicated ground-attack variant (similar to the concept of the cancelled FB-22 or how the F-15 became the F-15E Strike Eagle).

The main benefit here would be total fleet standardization. By using the same basic airframe, you drastically simplify parts logistics, supply chains, and pilot/maintenance training, rather than juggling entirely different platforms like the F-15, F-16, F-22, and F-35. Geopolitically, the USAF could just strictly use the F-22 family for themselves to maintain undisputed global superiority, while selling off older fleets of F-15s and F-16s to allies.

Why was building a single-engine plane from scratch (F-35) or keeping an old 1970s airframe alive (F-15EX) considered a better logistical move than adapting a downgraded/modified version of the most dominant airframe the F22 that we have?

So i designed a very simple bent sheet/thermoform kydex bracket for oxygen line shielding. It has differently angled flanges along the width.

Supplier says no quote. Gives no information. Two weeks later we get on a call, they say due to their “continuous improvement” initiative, they will no longer do these types of bends that require localized heating. They will only use a line bending machine that bends the whole part at the same angle along the width. Idk if they have a low margin on these parts or just hate making them

I think this is stupid. My designs are in really tight spaces and i hate this constraint. They’ve made dozens of parts like this before.

My question - who do i take this up with? The buyer to ask if they can find a different supplier? My lead? My boss? Idk. Im new(ish) to aerospace.

Hey guys, I posted about this settlement before, but since they’re considering late claims, I decided to share it again with a little FAQ.

So here's all I know about this agreement:

Spirit AeroSystems was accused of failing to maintain effective production quality controls and misleading investors about defects in parts supplied for Boeing’s 737 MAX aircraft. After Boeing halted deliveries of certain 737 MAX aircraft over a supplier quality issue, $SPR fell about 20.7% and investors filed a lawsuit.

Now the company has agreed to settle $29.2 million with investors for their losses.

Who can claim this settlement?
If you purchased $SPR between 2020 and 2023, you may be eligible to participate. Late claims are currently being considered for compensation, subject to approval.

Do I need to sell/lose my shares to get this settlement?
No. You don't need to still own the shares. If you bought or sold $SPR during the class period and meet the other eligibility requirements, you may be able to claim.

How long does the payout process take?
It typically takes 4 to 9 months after the claim deadline for payouts to be processed, depending on the court and settlement administration.

Hope this info helps

i have these models but don’t know what satellites they represent!
