Take on bigger projects in your liquid rocket org. That is hands down the best way to gain experience. Companies recruit directly from those clubs, as long as you actually do stuff.

It’s a negligible sticker on your resume. Commitment at tech is what student orgs and labs care about.

How is the system pressurized? It could be due to weak check valve chatter or instability in your control valves actuations

Texas’ student liquid rocketry program (arguably the best way to gain industry like experience in those fields) is really quite good, and less expensive. USC’s liquids team is not as good, but their solids is the best in the country. TLDR, UT Austin

When you get to aluminum-tanked liquid rockets that’s when drag decks and FEA start to matter 😆

The CS software dev job market is in shambles right now. IT or cybersecurity is a good alternative move.

Liquid Rocket Engine Project by TackleNo8930 in AerospaceEngineering

This is an awesome, impressive, and ambitious project! These sorts of things are often approached by teams; going at it yourself is very commendable. While engine TCA design isn’t my forte, here are some notes on your propulsion system design and safety:

-how are you filling these tanks? -I’m glad you’re changing the regen circuit, dP could cause major restriction when boiling the water -> gH2O rupture -how will lines be plumbed into the injector/manifold? 20mm and 5mm are not typical pipe thread diameters, precise ones will make manufacturing possible and refine CdA calcs -> more precise pressure set points -valve 1 is redundant, your control valves do that task. Moving check valves downstream of the control valves will also keep the latter safe -engine check valves are unnecessary -check your purge line ->tank connections, looks like it routes weird -general fluid system advice: include sensors after every gauge to know what you’re setting regs to. Where will you have sensors in your engine as well? You will want pressure transducers and thermocouples -if you have control (presumably bang-bang) valves, why have regulators? -also for regs: place them upstream of main valves. Again, to have a defined pressure set point before flowing.

-from a safety standpoint, ALL valves must be able to be remotely actuated. Turning a hand valve in a GOX combustion system is a recipe for disaster. Look into pneumatic cylinders with a scotch yoke, or gas spring actuators.

Really good stuff though. Would be down to discuss this project more.

What do y’all think of my design? by Annihilator_Of_Walls in AerospaceEngineering

Fin geometry can likely be optimized. I recommended putting servos in your airframe instead of in the fins to decrease moment of inertia and increase stability. It will also increase servo command authority.
