So I'm going through an Xfoil tutorial and I tried to change the number of panels on the NACA0012. After changing the number of panels when I try to get the updated airfoil, it gives "Input not recognized". Why is this error coming and how to get rid of it and the updated Airfoil geometry ?

Does anyone know where one can get in contact with a recruiter for internship roles for SWE or tech adjacent roles in DoD? Even referrals as well, if someone wouldn't mind, please?
I haven't had any luck with mass applications(1000+) being sent to land an interview(Raytheon, BAE systems, Lockheed, GE Motors, L3Harris, etc).

I am also willing to post my resume if anyone wouldn't mind giving criticisms? I am a CS and Math student with a 3.1+ GPA from a T10.

Thanks!

Hi everyone!

I just accepted a early career software engineering position with Lockheed Martin MFC for their Dallas office. I just started process to get SSC.

I received an email asking me to provide a tentative start date. I graduate in May 2025 and have no idea what date is reasonable to give. I'd really prefer September 2025, but I have no one to ask whats typical. I'm the first in my family to go to college in US and am very confused.

Any advice would be appreciated!

I'm a final year mechanical engineering student working on a project related to jet propulsion and compressible flow for my fluids course. My uni recommended the Modern Compressible Flow: A historical perspective by J.D Anderson book for this course. I've found this book to be quite nice & interesting to read, but I felt it focuses more on the fundamentals of compressible flow and not so much on the practical application of jet engine design and analysis. I came across the NASA Technical Report Server and it seems to be a goldmine of information, but also slightly daunting in the sense that there is so much to go through. Anyone that's familiar with it that can give me some tips on how to navigate and use it in the best way?

I have an offer with LM and the PTO is lower comparing to other people who are in the industry. It says I will accure 6.67hrs monthly, but not able to use until after the 90day probation period. Along with that it also mentions 48hrs business time starting after Jan 1st thats prorated annually. Does anyone know if the time off is negotiable for an offer? Or changes when in the union?

Which place anywhere in the world wherein it gives the best opportunity for aerospace engineers.

I am mechanical engineering student and I'm interested in aerospace, it's just that I don't know where to start from. I'm confused whether I want to do rocketry or aircraft design. I know solidworks and fusion 360. I also want to build the skills required for this field. If anyone can help me out, I would deeply appreciate it

Hello I am a level 3 employee, and I am moving to level 4 in a position that I have more experience on. However, I accepted a low salary when I first started because I wanted to join Lockheed Martin. And currently I am in the low range of the new position. Is there any certain policy for salary increase?, as I am hoping to be at least in the mid salary range of the new position, which is around 20% increase from my current position, does anyone know if that is feasible? Or there is a policy restriction over here? Anyone had the same experience in the past? Thanks

I’m first year AE student and I’m really interested in programming and electronics. I know C/C++, python, basics of electronics and I’m starting with Arduino. Should I switch to EE/Embedded systems or maybe it’s good to stay and go on with AE. My course does not have specialisations related to avionics/GNC/UAV.

I would also like to ask you if you know some other aerospace jobs which are interesting and in demand. I heard about Fluid dynamics (I like maths and physics), but I don’t know if it’s in demand.

Location: Europe

As the title suggests, I am basically wondering if anyone knows what Lockheed tends to give for international relocation packages. I currently work at Lockheed under AERO, and the jobs are the same thing I'm doing now. I applied for 2 jobs in Japan (coming from the US), and haven't been able to get any Info on this.

Of course, I don't have the job yet, or even an interview, but I like to get ahead of stuff like this, especially since it would be a big move. Have not had a chance to talk to my manager about it either.

Any information would be appreciated, thanks!

Northern Lights are caused by bremsstrahlung. With electrons. Can you think of what might get extra electrons in it? Like if it were something you’d do to an aircraft...It’s something inside an aircraft that you do to parts of an aircraft. It’s something you do to a aircraft. Something with the bypass that would cause a lot of electrons that then turn green. No additives, but the Green happena after. What is it?

Hello Airbus Community,

I am an aerospace graduate with a specialization in systems and control, currently preparing for an interview for the Flight Control Law Designer position at Airbus Commercial Aircraft.

I would appreciate any insights you can provide about the typical challenges and projects an engineer in this role works on. Detailed examples would be especially helpful to help me understand what to expect and to prepare effectively for my interview.

P.S: Any advice or tips for the interview would be greatly appreciated.

Thank you very much!

Im in 11th grade and i live in eu. I would love to work in this field but i am an average student and dont have a lot of money for college. For more context im a student at a "prestigious" high school in my country taking classes in STEM mostly. I have good grades, I never had my annual grade lower that 9.50/10 but i dont have any extracurricular activities or partcipated in high school championships like the math olympiad. Could i get in a good university in eu or usa preferably and actually have a future in aerospace engineering? And also if extracurricular activities are a must what should i do? But more especially do i still have time? Im ok with taking a gap year if necessary to follow my dream of becoming an aerospace engineer

I graduated with a degree in Mechanical Engineering in 2023, specializing in aerospace and automotive engineering. During my senior year, I focused on applying to aerospace jobs. However, despite having some interviews, I struggled to land a position in the aerospace industry. This was partly due to the challenging job market and partly because I lacked internships in aerospace, which made it difficult to stand out.

After graduation, I spent 9 months searching for a job in aerospace but eventually found a position as a Mechanical Engineer in the manufacturing industry. I worked there for 6 months, but due to financial reasons, I decided to leave for a higher-paying opportunity. Currently, I am working as a Project Manager in the construction industry and I absolutely hate every second of it.

I am 23, about to turn 24, and it will soon be 2 years since I graduated. I am still passionate about transitioning back into the aerospace industry but would prefer to avoid pursuing a master’s degree. Instead, I’m looking for strategies or steps I can take to break into aerospace while applying for jobs on the side.

Hello. Within the past year, I have started collecting aerospace memorabilia (anything from engine parts to models that were given as gifts to the teams to material samples to photos you name it) and usually, I find my unique pieces either through my local stores or through connections but I was wondering if there are any credible websites or sellers online that sell such pieces. Earlier today I was searching on eBay and although there seem to be nice pieces for sale I am wary about buying such uncommon things on eBay since there is a high chance it could be a scam. Any links or suggestions would be appreciated. Thank you.

What is the ball of an FDAI (8-ball) made of?

Hi, I'm trying to learn some Areodynamics at present and want to model the thrust, power and efficiency for a coaxial rotor (ie. the Ingenuity Mars Helicopter, but on earth).

I'd like to work through a few different scenarios, all calculating the above three parameters:

• Hover
• Assent
• Horizontal Translation

I've found these sites that help me understand how to break down the problem for a single rotor, but adding a second rotor makes the math a lot more complicated for me to work out alone.
(I don't like the second site as it skips over alot of the explanation and introduces a random constant that isn't explained either)

• 1: Static Thrust and Power: https://uav.jreyn.net/quadcopter-design/step-3-static-thrust-and-power
• 2: How Much Power Required to Hover a Drone: https://justdrones.com.au/how-much-power-is-needed-to-hover-a-drone/

If you can point me towards some research on this problem or extrapolate on the math in the first link I'd be very grateful.

Thanks :)

So, my internships were research positions with my professors. They weren't prestigious/with private companies. I'm curious how I can leverage that experience to get into any defence contractor.

Hi. Currently in my final year as an undergraduate in Aerospace Engineering from India. Planning to fo masters, preferably in Europe. Any advice on applications, SOP or in general?

More inclined to universities in Germany/Netherlands such as TU. Any other ones to keep an eye on?

Wer sind wir und woran arbeiten wir?

Hallo zusammen! Mein Name ist Toni Langer.

Vor einiger Zeit habe ich hier auf Reddit zum ersten Mal öffentlich nach Mitstreitern für mein Projekt, dem Bau eines echten Jetpacks, gesucht und wurde fündig. Zusammen mit Dominik Flaßkamp habe ich daraufhin die Vereinigung MidAir-Inventions gegründet und mit der Arbeit begonnen.

Ich (Toni) persönlich habe einen Background in Elektrotechnik als gelernter Elektroniker für Geräte und Systeme und habe mich später auf additive Fertigung spezialisiert.

Toni LinkedIn: https://www.linkedin.com/in/toni-langer-111840245/

Dominik ist gelernter Schweißer und studiert Wirtschaftswissenschaften.

Dominik LinkedIn: https://www.linkedin.com/in/dominik-fla%C3%9Fkamp-87b4a21a3/

Was haben wir bisher erreicht und wo stehen wir?

Gemeinsam haben wir in wöchentlichen Online-Treffen ein Konzept für die Konstruktion des ersten Prototyps des Jetpacks erarbeitet und CAD-Modelle erstellt, mit welchen wir auf Hersteller und Dienstleister zugehen können. Wegen

Was ist das Problem?

Wir befinden uns nun in der Phase, in welcher wir die ersten Komponenten bestellen und anfangen, erste Aspekte der Konstruktion in physischer Form umzusetzen. Hierbei stoßen wir nun auch zum ersten Mal an die Grenzen unserer Kompetenz als Team: Software.

Wen suchen wir?

Wir suchen konkret nach einer Software entwickelnden Person, welche mit den meisten der folgenden Punkten Erfahrung hat:

- Mikrocontroller- und Einplatinencomputer-Programmierung

- Kommunikationsprotokolle und -schnittstellen: Erfahrung mit verschiedenen Kommunikationsprotokollen und -schnittstellen wie I2C, SPI, UART, CAN-Bus

- Objektorientierte Programmierung (OOP): Sollte über fundierte Kenntnisse in objektorientierten Programmiersprachen wie C++, Python oder Java verfügen, umstrukturierte und wartbare Software zu entwickeln.

- Datenanalyse und -verarbeitung: Erfahrung in der Erfassung und Verarbeitung von Sensordaten und Daten anderer interner Komponenten

- Kenntnisse in Hardware-Nähe: Grundlegendes Verständnis der Elektronik und möglicherweise der Fähigkeit, Schaltpläne zu lesen, wird von Vorteil sein, um besser mit der Hardware zu interagieren.

Wie sieht die Zukunft aus?

Wir sehen die Zusammenarbeit nicht nur als kurzfristiges Projekt zur Entwicklung eines ersten Prototyps, sondern wünschen uns eine langfristige Partnerschaft. Unser Ziel ist es, das Team kontinuierlich in Anzahl und Kompetenz zu erweitern, um zukünftige Innovationen voranzutreiben und eine Firma aufzubauen. Deshalb suchen wir nicht nur jemanden, der uns bei der aktuellen Herausforderung unterstützt, sondern auch eine Kollegin oder einen Kollegen, der mit uns die Reise in die Zukunft fortsetzt. Die Möglichkeiten sind vielfältig, und gemeinsam können wir Großes erreichen!

Wenn dieser Post dein Interesse geweckt hat, melde dich doch bei uns auf LinkedIn.

Hello,

I work at cloud software company, that provides a Quality Management solution for manufacturing companies around the world. The HQ for the company is based out of Mexico, and we have all the industry-standard information security practices, including ISO 27001 and TISAX certifications.

However, a customer of us is asking for ITAR compliance. I have spent some time reading about it, and I basically understand this:

• We required some technological controls: data encryption, information residing in US servers, and things like that. We comply with all that. Our cloud provider, Azure, is ITAR compliant, even in its non-gov version.
• We need traceability of information access by non US persons. I think we could do that (as we log all our team's access to production data when absolutely required), but I have not found a specific requirement.
• Registration with the US Goverment. Looking at the DDTC website, foreign companies may register and be ITAR compliant.
• We need to establish clear boundaries on where our responsability ends and our customer' starts. We must make sure the owner/administration of the account in our system is ITAR compliant. If our customer then gives access to unauthorized people, it's their problem, not ours. Of course we must put that in writing.

I have found a lot of information on ITAR compliance when it is your data, but none other than quick high-level discussions on ITAR compliance when you provide a service to ITAR compliant companies.

Does anybody here know more about this that might shed some light on what I am missing? If there's a specific, official document outlining the requirements, it would be great. I have only seen the official list but it's more aimed at manufacturers.

Thanks,

Luis

Hey guys,

I'm trying to design a CD nozzle with the exit to throat area ratio 4:1.

The throat radius (Rt) is 0.125 in and the exit radius (Re) is 0.25 in.

If I consider the half angle (θ) of divergent section to be 15 degrees, I get the length of the divergent section to be 0.466 in. Using this relation:
Lc = (Re-Rt)/tan(θ). I found this formula in the rocket propulsion elements book.

My question is: how do I calculate the length of the convergent section ("B" in the image below)? books say it doesn't matter what the length but then how would I ensure choked flow (Mach 1) at the throat? I need to have supersonic flow out of the nozzle.

Also, what would be a good estimate of the length of the chamber before the CD nozzle? ("A" in the image below).

Thanks a lot for the help!

Hi

I'm a European student currently completing my bachelor's degree in Aerospace Engineering. Due to limited investment in the industry in my home country, I am looking to pursue research opportunities in the US. I've spoken with some professors locally, and I'd love to hear from those who work in or recruit for the aerospace industry, particularly in companies like SpaceX, Aston Martin, NASA, etc. Here are the potential paths I'm considering:

1. Complete my bachelor's degree at home, then pursue a master's and PhD in the US. This would be the most costly option since studying in my home country is compensated, but it could open the most direct pathway to US research and employment.

2. Finish my master’s in my home country and spend one semester at a US university (e.g., University of Texas at Austin or Purdue). After that, I’d return to complete my degree at home and potentially leverage connections made during my stay to pursue a PhD in the US.

3. Get both my master's and PhD in my home country, then pursue a postdoc in the US. This would save me tuition fees and provide a significant stipend (equivalent to a six-figure salary in the US), while still opening doors for postdoc research in the US.

4. Complete a PhD in my home country and build my profile with publications. Afterward, I could potentially use collaborations to transition into the US research market.

I apologize for the lengthy post, but I’m hoping to get insight and advice on which path would be most strategic for entering the US aerospace field.

Thanks in advance for your thoughts and experiences!
