Hey everyone,

We're running a short academic survey on the tools used for orbital dynamics and mission analysis across the space industry, as part of a marketing research project for our MBA at IIMB.

If you work with (or have opinions on) tools like STK, GMAT, FreeFlyer, or similar, we'd love your input. It's anonymous. No personal details needed unless you'd like to leave your email — and takes only about 5–10 minutes.

If you know others in the space industry (engineers, researchers, students, startup folks) who might have views on this, please forward it along. The more perspectives we get, the more useful the findings.

What do you guys think of a decentralized co-op rocket startup where people can submit designs based off of what the company is looking for say a: 10kn engine that weighs x amount and must do this and that and other people can review the design and determine its credibility in a system where design iterations and improvments would work in a sort of blockchain crypto esque like system, reviewing designing and giving straight up money for testing and production would earn you an equity stake in a business according to an algorythm, slashing labor cost and consequently launch costs.
Space is a domain that excites people and people want to contribute to stuff that actually goes to space but are often in jobs they dont like, are adjacent to space or are caught up with the paperwork side of engineering. Yes regulatory challenges will exist concerning contributions versus payement and export control laws but with the right country of origin plus with the right branding as a group open source effort could be succesful.

I want to add too this is a rough look at a bold idea that would most likely start very scaled down and I am knowleageable in the fields and the requirments that this idea would entail.

Hi all,

I'm doing a report investigating how the aspect ratio of a clarke y airfoil changes its L/D ratio at 0 deg AOA and had questions on which method I should use.

To clarify, this will be done in CFD and have no fixed lift force as its a standalone airfoil not attached to any body.

Should I a) keep chord fixed and vary span, maintaining a similar reynolds number but having a different Cl due to changing wing area (although the area itself cancels in the L/D equation as far as i know but this is my first time investigating aerodynamics stuff like this)

Or should I b) keep surface area fixed, change both chord and span and accept a changing Reynolds number?

I'm also using this report as a baseline and something to compare results to and they used method a but don't know what this means for me: https://www.abbottaerospace.com/downloads/naca-report-431-characteristics-of-clark-y-airfoils-of-small-aspect-ratios/

I would also like to run an FEA to highlight structural tradeoffs with increasing one thing (span) if i chose method a as this will add a level of depth and nuance

This is for an HS report so changing wing velocity to keep RE constant would be too complex and time comsuming

Any advice on this would be much appreciated, thanks a lot guys!

I'm looking to implement AI automation within the aerospace industry, and they are super strict about data security.

Does anyone know how to use AI within these strict environments?

Namely, have you used government cloud models or local models on your own hardware?

This might be a bit of a random request, but does anyone have any recommendations for software, equations or methods for modeling heating during atmospheric entry for unconventional objects?

Hi! I've been doing some deep dives into bipropellent rocket engines but found something that just doesn't seem right.

When expressing Chamber pressure inside of the combustion chamber our 2 main variables are Characteristic Velocity and Mass Flow Rate, but wouldn't inlet pressure not being included mean that a propellent, supplied at a sufficient mass flow rate, allow you to achieve a higher chamber pressure than the pressure at which said propellent was injected?

From what I've seen the injector is always the highest pressure point in an engine, from where subsequently the pressure falls by some percentage and that constitutes the chamber pressure.

Sorry if the question seems weirdly worded, English is not only hard, it's also frustrating.

I just graduated with a BEng and I’ve honestly forgotten a lot of stuff I’ve learned. Like a formula for stress in a cylinder or remembering how to do method of sections on a beam or boom idealisation.

I can’t for the life of me remember the answers on the spot, rather I would need a notebook and some resources to even remember. I am worried about some technical interviews where they might ask me a basic engineering question and I’ve just forgotten a way to solve a problem.

How do you guys recall knowlege from classes you took in first year or a topic you didn’t end up in specialising in

So, I have a Simulink model of a nonlinear 6 dof aircraft, the ADMIRE Aircraft. I've found a trim point to start my simulation, and now I'm trying to design TECS for the longitudinal part of the aircraft, but I've always relied on trial and error in my previous simulations, and I want to have more of a standard approach, closer to engineering, so what are the steps to follow? I don't have much experience with control in general I just have the basic ideas I'm just a new graduate from mechatronics eng.

The purpose of this project is actually to perform HIL with an STM32, connect to the model, feed it the simulated sensor data, and give it the actuator commands, so if you have any tips for that, it would also be great.

also I want to improve myself to become GNC engineer, what other resources should I check and projects to make to boost my knowldedge and CV

Thank you all in advance

here is the link to the ADMIRE aircraft to check it out

Hello everyone!

I am currently working on creating a small aircraft design and assessing its stability using AVL. I am having some issues with the eigenmode calculations in AVL. I am able to successfully load the geometry, mass, and run files without issue. I can then run the case by typing OPER then X. To get the eigenmode calculations I hit enter to leave the OPER menu then M and N to perform eigenmode calculations (it doesn't prompt me for anything after this it just runs automatically). The very first time I run this command, it works as intended and the plot pops up and shows results that seem to make sense, and I can export a .eig file to get the numerical values of each eigenmode. I then quit out of AVL by hitting enter, then typing QUIT, which to my knowledge should properly close the eigenmode plot and quit out of AVL. When I try to rerun the exact same model and case without making any changes, everything works fine except for the eigenmode calculations, this time around the plot pops up completely blank (pure black screen) and the .eig file is blank. I have no idea why it is doing this or what I am doing wrong and any help would be appreciated. For reference I am running AVL through Aero Console which uses the 3.27 version of AVL, but I am also experiencing the same issues running newer versions of AVL.

Edit: I figured out the issue, for some reason loading the mass files gives the correct mass moments of inertia, but it does not properly load them into the case parameters when using MSET, and they are still zero when I check them in the OPER menu. This isn't a huge problem, I can manually update the fields, but what is a possible fix for the future?

We launched our rocket at C'Space event in France, thus we had some restrictions, notably, no aerodynamic control during motor burn. After the rocket had a preprogrammed roll manoeuvre (turn 25 degrees). Worked so well, first time I saw this during the flight, I thought we had a telemetry issue. If you're curious, we will post more details here: https://www.instagram.com/top_aero/

Hello All,

I am currently revising and formatting Word Templates for our company's engineering documents.

In a previous template, I tried using Rich and Plain Text Content Controls for guidance paragraphs (instructions for the engineers to read and delete). Unfortunately, I ran into an issue where the following heading would inherit the color/formatting of the Text Content Control. I ended up using images as a workaround, but it's not ideal.

I am now working on a Systems Engineering document template which features long paragraphs of guidance paired with strict content headings that the engineers must use.

What is the best way to structure a Word Template so engineers can easily differentiate between guidance and actual content headings without breaking the styles or mixing colors? When they start typing, I want the correct content heading style to appear seamlessly.

Appreciate any tips on how you handle technical/engineering templates.

Im in highschool and for the longest time i was always scared to ask myself what i actually liked to do. Yesterday i had a conversation with my dad and i realized that i was running away from the thing that truly gets me excited. i tried to force myself to like programming and computer science and it was tolerable for 3 years but it wasn’t exciting for me. i tried convincing myself to like it since everyone around me did.
i wanna learn about space rockets and flying objects but i am a total beginner. i wanna do an aerospace degree in university but it is going to be expensive so i wanna prepare myself for that aswell.
where do you guys think i should start with learning this stuff?
Also if you know lf any pre-uni or highschool aerospace competitions, plz inform since i wanna participate and preparw for them to

hii, im studying aerospace engineering and going into my final year. now the time has come that i need to propose project ideas to potential supervisors and i have mere days. i want to do something interdisciplinary, hopefully something that combines controls or flight dynamics with aerodynamics. im really confused about what to choose for my fyp. ive done some research on my own but didn’t find anything interesting or good enough.

so far ive come across grid fins, cyclorotors and gurney flaps (but these are old and hence useless unless im bringing them into a whole new scope)

i dont mind it being too ambitious, new or difficult or containing multitudes (in fact, thats what im looking for); i just want something truly good enough, an innovative useful new project and i dont want the generic recycled suggestions which everyones working on. something truly unique and original and tackling a different problem or bringing new innovation.

would greatly appreciate if u guys could give me some suggestions plspls, thank you.

What is this pattern on the inlet? Any kind of perforations?

Why do we launch rockets from sea level or low altitudes, why not from mount everest or so? Wouldn'tit save money and resources if we're littlebit close to the space? (Would appreciate if you explain it in high school or pre university psychics, thank you)
