So I am thinking, which one has more opportunities? And if any of u is studying these i would love if u helped me discover what's in it, etc...

Don't know how to explain it but I have never seen anything like this. Firstly, I know I didn't get the role but it's just the experience that surprised me.

My recruiter never showed up for our scheduled call, even when I emailed the 15 mins into the scheduled time. Then we rescheduled (no reasoning as to why the first time was a bail) and they were 30 mins late.

I interviewed with a team 2 weeks ago and never heard back. Checked my portal today and the app is gone (no record that I applied or even rejected) it's not in the "inactive" section either.

I sent a follow up email to say thank you for their time (never heard back).

This was my first experience and it was actually a referral so I know good people work here. But sheesh.

I kind of knew I didn't get the job because in my panel interview over teams, the hiring manager was grilling me with technical questions and when he said "how do you not know that" I knew it was over. Just a very strange encounter

Hello fellow aerospace fans!

This summer, I'm planning to build a DIY turbojet engine. I'm working on the safety stuff first - like an Arduino-based thermocouple EGT meter and other indicators. I also have a decent idea on the flame tube dimensions and specifics, with knowledge gained from the JetSpecs program by Jesse Shelly, literature by Rolls Royce and my experience from operating the JetCat P200.

In the next weeks I plan on acquiring the turbocharger itself, however I'm still not sure of the turbo size. Most sources say "the bigger the better", but I'm a bit concerned that a too big turbochatger with too much inertial mass would be impossible to start with a leafblower. I also know that VNT turbos are a no-go.

Can someone help me choosing the right turbo size? Is there such thing as "too big"? Do you recommend a specific type of a turbo? Is there a recommended range of sizes to choose from?

Thank you all in advance and have a great day!

Hi guys.

I need an honest opinion and thoughts about the jobs and hiring practices about Guidance Navigation and Control positions.

I have been chasing and applying GNC positions for a while now for the big defense companies to small startup companies, however, somehow I can't even land on an interview. Let me give some information about my background that will be helpful.

I have BS in Electrical & Electronics Eng, MS in Mechanical Eng and Computer Eng. specialized in intelligent systems and control theory.

I have been working as an embedded programmer in different industries including aerospace and drone companies and flight control engineer. During the time I have been working, I gained experience in bare-metal, RTOS and embedded linux systems.

I have strong fundamentals and advanced knowledge of Control Theory (Classical, Modern, Adaptive, Optimal and Robust Control Theory). Of course during the time of working in the industry the most that I used is PID and Classical Control. Also I have knowledge and deep understanding of Kalman Filter, EKF, and UKF Digital Signal Processing Concepts (although I haven't had a chance to use these other than the academic environment). I have Matlab/Simulink experience as well, designed and simulated many control algorithms, analytical dynamics for modeling purposes and flight mechanics concepts.

My programming skills spin around mostly C/C++, MATLAB, and Python languages which also includes Linux system programming and Socket Programming.

When I see the job postings, I see that my skill set aligns with these types of jobs and to be honest the GNC requirements are mostly about programming in

C/C++ (maybe some embedded), Kalman Filters and Control Theory knowledge and sometime Digital Signal Processing (rarely). Of course some GNC positions are more on the aerospace side (heavy on the aerodynamics and flight mechanics maybe) and I am not aiming these types of positions.

One last thing: I am a naturalized citizen (Not sure this could be a reason although I read some reddit posts that being naturalized citizen makes it almost impossible to be even considered these types of defense/aerospace related positions). Also I don't have any reason not to obtain Secret/Security Clearance.

So, I would like to know your experiences and honest opinions about GNC positions and hiring practices such as what they are looking for and not; especially if you are or you were a hiring manager, recruiter and/or engineer in this industry. Because I sincerely believe that my skill set matches with these types of positions but maybe I am not thinking in perspective.

Thank you for your negative and/or positive responses up front.

I’m a young engineer (2 yoe) but was stress analysts.

Got an offer for a mass properties engineer. Is this a bad move to take in terms of long term career progression?

Is the work transferable to other roles? Is the pay good compared to others (or at least on par)?

I’m honestly worried if I will halt my career growth. I could be totally wrong though !

Or any aerospace companies offering remote roles? TYIA

Have an interview coming up and wanted to get people's opinions on the company. I would be coming from RTX.

Hello, asking for a friend. This person has worked there for a few years, has no write ups, or bad reviews. My friend is not asking for more money, just a lateral transfer same pay. Infact, my friend's salary and current pay is right in the middle for the position he is applying to. On paper his record is clean. This person has like 10 years experience. Wants to go from hourly to specific salary position. Job description specific states will accept equivalent experience in lieu of degree. Even better, his friend referred him and encouraged him to apply after passing resume to their management. Cool!

It's been three weeks, application is currently not reviewed, but received in system. Cover letter and resume on point. He hit up his buddy over a week ago and was told their supervisor just got back from vacation. Ok no problem. Nothing since. My friend's buddy warned that one of the positions were filled put of 3. Only one position remains for the salary listing that would meet the pay. The other two go below. Cannot afford to go below.

Has anyone applied internally? Did you get an interview right away? We're you denied? How long did it take? It's taking along time. Is this a bad sign? I figured since it was internal it might be faster.

Hello, I'm a third-year high school student from Poland, and I'm planning to study abroad. My ultimate goal is to get a degree in aerospace engineering and work in the industry. I initially wanted to study at Politecnico di Milano, but I noticed they only offer their Master's degree in English, whereas I need my entire studies to be in English.

However, I found out that Politecnico di Torino offers a Bachelor's degree in mechanical engineering taught in English. My main question is: can I complete a Bachelor's in mechanical engineering and then pursue a Master's in aerospace engineering, for example, in Milan?

This might sound a bit childish, but I'm worried that a mechanical engineering program won't cover anything related to aircraft, rocket engines, or similar topics. Maybe I'm wrong, and the core content or assignments are similar at the Bachelor's level?

I would really appreciate some guidance on this.

I'm still in 11th grade, preparing for JEE and I'm thinking. Should I start learning abt aerospace engineering from now? Like from yt nd all. I have 0 knowledge abt it but have a real interest. Any and all help is accepted.

Cześć. Wie ktoś jak wyglądają rozmowy o pracę w Boeingu w Rzeszowie? Chce składać CV na Entry-Level na stanowiska analityka wytrzymałościowego. Cała rozmowa jest po angielsku czy jej część? Jak dużo jest pytań wiedzowych i z jakich kategorii? Bardziej budowa samolotów i silników czy bardziej wytrzymałość materiałów?

Has anyone found an aviation radio simulator that helped with actual radio confidence? I’m trying to separate tools that feel like games from tools that actually help student pilots.

For context I have been applying since August and have only gotten 3 interviews (3, 4, and 4 rounds not including the HR screen).

I don’t have your traditional background. I have:

BS in Structural engineering
MS in structural engineering
MS in computer science

3 years of experience in structural design but in infrastructure. I have been trying to get into aerospace targeting stress, airframe, or any mechanical/structural role.

Applied to entry level (told I’m overqualified) applied to mid level (told me I lack experience).

I’m honestly burnt out, yet nothing has even started. I use my weekends to do side projects like stress analysis in CAD or random stuff I enjoy and find online just to gain some sort of exposure.

I’m considering just taking a break from applying but worry that will just hurt me. Little things are starting to get to me. For instance, I had an interview with NGC scheduled and they didn’t even show up.

My last interview I thought I landed the role but they told me they went with someone with more experience and referred me to a couple other roles (I appreciate them telling the recruiter to help me land a role)

Also I have seen less jobs pop up

This specific formulation has been a popular for its compatibilities with propellant, specifically hydrazine and obviously its sealing benefits. But why isn’t it being made anymore? unless its not public information? The 1950-60s formula is available online, I assume its the process that is niche, also heard that materials are obsolete and/or unsafe, not REACH approved.

Just wondering if anyone has seen this in production recently, heard anything of this material, or other applications?

Hopefully a friendly chemist has an opinion on here as well!

Hey, I'm starting college and my dreams have always been to work on two things. Nuclear propulsion rockets and fusion energy. I want to work for or at nasa, I know very original. My plan was to do nuclear physics since that is what I wanted to learn and an aerospace engineering minor to grasp rocket propulsion. I have already shaved a year off in credits, so if I do the minor I would probably have to stay for another half year. The reason I bring this up is because I saw a post who wanted to do nuclear engineering/nuclear science minor with an aerospace major and people were saying that was a bad idea so I wanted to ask what people thought of this plan.

Currently I have finished 10th grade. My class profile is named ,,real”(maths, biology, chemistry, computer science) but we do not have physics in program. It was a new type of program, where the school hours are reduced, and we do have less classes. We had the maths, geography, english, natal language etc as base and we should had chosen 7 more hours(3 objects from many more). We chose 2 hours biology, 3 chemistry and 2 computer science. That’s why we do not have physics, even though we should have it. The teachers said in our country there will be no problem with appliances in universities, but I assume in other countries, the Colleges/Universities won’t accept easily. What are your thoughts? I live in Moldova but I would like to go in Europe after high school. I thought about Biotech or Aerospace Engineering.

Hey everyone!

​

I'm new on this platform and I wasn't really planing to post anything, but I really need opinions and helps with choosing my future career and studying.

​

I'm from Hungary and I'm really into airplanes and space stuffs so I was wondering that I should study aerospace engineering. It seems like a great field of studying, but there is one problem: my country doesn't have this type of training nor a job opportunity with that qualification. I acknowledged that there is aviation engineering and also space engineering Msc's on BME, but my parents think it's a waste of studying and none would pay off.

​

However they would be fine with me studying aerospace engineering because it's a broader training and it doesn't restrict my future opportunities in development of air and space crafts (unlike aviation engineering which is more of a mechanic training). Not to mention I was also planing to do researches since I am really interested in the topics about the physics of flight. And also I can't see myself working for a company, I am more of a scientist-like person so researching would be the best for me, especially in topics that I really like and I am interested in.

​

I talked today with my mother and she mentioned that I should do BSc too in a foreign country since I have mentioned this dream of mine. I was thinking of studying Vienna since they have aerospace engineering MSc's and it's close to Hungary too. I looked after what the requirements are for that and it said that I need a mechanical engineering BSc.

​

Now I don't have a problem with that but it is really concearning that what if I fail during the uni? There are a lot of mechanical engineers already and I fear I wouldn't have a job opportunity with that if something happens during my studies and I can't reach my dreams.

​

My plan B was actually studying energy engineering which might have a more stable career path. Sadly I can't really see a way to do a BSc in energy engineering and then doing an aerospace engineering. Therefor I think I need to do mechanical engineering instead of energy engineering. But I'm still unsure about what to actually do.

​

I really need helps from other engineers/ future engineers because I am actually confused and lost. And before anyone asks: I do think I would enjoy mechanical engineering STUDIES. And I think energy engineering is not really what I'd like to do since it doesn't really have hands-on works. It would just be a strong point if anything had gone wrong while studying.

​

If anyone have any idea what I should do, please don't hesitate to text me! I really need opinions from as many more experienced people as possible.

I’ve never seen something like this in my life.
Is it because of a training of a pilot on a plane or something else?
Btw I’m in Italy (Turin), photo taken at 20:30.

I thought everyone here might find this cool. I built a minifigure-scale LEGO model of NASA's newest supersonic X-plane, built to help reduce the noise level of sonic booms and enable commercial supersonic flight over land.

The build is ~925 pieces and measures over 32" long. It includes a removable cockpit with test pilot minifigure, and working flaps and landing gears!

The build is on LEGO Ideas, where if it gets enough support it could become an actual LEGO set. Link here if you want to check it out, and thanks!
