Hi this might be busy basic for you all but thought I might share an infographic my mate made

Cheers!

Hi guys, I think this might actually be my first post here. This summer I designed and built a wind tunnel for my kids and wanted to share it. It ended up being a much bigger project than I originally expected, be ware of time expectations if you try it, with quite a few very late nights over the summer, but it has been a really fun experience.

My kids are 8 and 10 and they can now test their toys, cars, airplanes, wing profiles (well wing profiles is for me 😊), or basically whatever they want to put in there. What is PRICESLESS is seeing them try to predict what will happen before turning it on for a given toy.

We have built quite a few experiments at home over the years, but I would say this is probably the best STEM "lab" we have made so far. The wind tunnel itself is fairly standard. One thing I added is a gear system controlled by a servo so they can change the angle of attack of a wing profile while the tunnel is running. The fan speed can also be controlled, all with an android app that an AI took less than 20 minutes to fully build, connected to a ESP32 (with Bluetooth) board.

I designed everything in Fusion and then built it with 3d printer at home. There are some good resources online about building wind tunnels, but to be honest I found that none of them were really "complete" once I started actually building one. There was a lot of trial and error and quite a few things that looked perfectly fine in CAD and then didn't work at all in real life, specially tolerances.

So if anybody is thinking about building one, I'm happy to answer your questions and share what worked for me, what didn't, and especially some of the painful mistakes that might save somebody else A LOT of time. I cannot emphasise enough the "A LOT" of time.

If there is interest I can also post the STEP files. Personally, I never really understood why people only share STL files for projects like this. The useful part is having the STEP files so you can actually modify things and adapt them to your own dimensions, needs, experiments, etc. UPDATE: STEP FILES: https://grabcad.com/library/working-wind-tunnel-1

BTW, I hereby confirm that NONE of the Paw Patrol vehicles are at all aerodynamic 😉

I made this water based wind tunnel for my room, lmk what you think. Think I could add to portfolio or something?

By far one of the most difficult processes I’ve ever had to go through. Learned so much about what worked and what didn’t work. Out of 399 applications, almost 70-80 of those were referrals and high up managers. One of those referrals was an astronaut ( didn’t result into a job ). Only about 5-10 referrals brought interviews.

I ended up getting my dream aerospace job after 444 days. And it was all worth it.

Final thoughts:

• I got my offer literally applying through the website. No referral

• Consistent is key

• Quality over quantity

• Learn from every single interview

• don’t settle for a job you don’t want to do

• if you’re still in college, get involved ASAP. Do clubs/research/start up/ code apps

• there is usually no “perfect” time to apply but based on my data, between July- September is the absolute best.

• Study first principles and general structural questions for entry level technical interviews. Use first principles engineering books to study

• voice your thoughts when doing technical interviews, took a lot of practice, but generally just try and figure out the answers with more questions and really try to think down to first principles ( Is it electrical? Heat transfer? Dynamics? Structural? )

• using chatgpt to create technical questions related to the role would sometimes give me questions that recruiters/ hiring managers would actually ask me (Usually kind of a gamble).

• Do mock interviews with your school or friends

• I went to a good school but career fairs were pretty worthless and never amounted to any true leads. May work for others but for my case was pretty un-helpful

If you have any questions, please feel free to reach out! I had a lot of friends of mine who were extremely gifted and skilled who weren’t able to find a job in aerospace at all. It really makes me sad to see and I’d like to help others in this process if I can.

Sorry if this post violates any rules. I just had a random thought, which is the least aerodynamic shape possible for a ship? Assuming you are forced to place thrusters at the most optimal place for minimizing air friction. Would it be a cube? A pyramid? A donut?

Title. Ive just finished designing this aircraft and was wondering if anyone could tell me if this will fly. Thanks!

Isn't it cool?

Eg

So that control surface is the aileron, right? I noticed that during turbulence it was moving in the opposite direction as the plane go up and down. I did a bit of Googling, but I wanted to understand it better.

Is this movement automatic? From the way it looks, is it adjusting the wing’s lift to smooth out the turbulence kind of like how a vehicle’s suspension works?

What does the career path look like for someone who does the modeling for aerospace, such as the F-35? How different is that surface modeling compared to automotive and industrial design? I would assume similar fundamentals but wonder where the skillsets or jobs depart. Would love to hear from people who have done the real thing.
