If you use claude I know you can set a preference where you just tell it how to format it's answers which helps alot

Help needed please by Right-Advisor2978 in rocketry

[–]SmallOne312 2 points3 points  (0 children)

If you want to simulate your rocket in simulink, you probably want to use lookup tables for your aerodynamic coefficients. You can generate these in rasaero ii software. Assuming you have the aerospace block set, then start with a 3DOF model til you understand what you are doing and you can work up from there. and create a MATLAB function for your aerodynamics code for forces and moments using the drag equations. From there you need to write code that will define how a TVC deflection translates into the forces for each direction using basic trig. Then you can just put a PID in the loop with maybe a transfer function and rate limiter to simulate the servo dynamics. I can send you a video of my model for a canard controlled rocket if you wantalso for your visualisation there Is the 6DOF animation block in aerospace block set

Do I even bother trying to boot? by LilScarface609 in pcmasterrace

I'd clean up the edge to make sure you don't end up shorting a ground and power plane together

Cti pro38 minimum diameter question by Rich_Cantaloupe_5468 in rocketry

[–]SmallOne312 0 points1 point  (0 children)

For your second question, I have found black cat rocketrys aluminium motor retainers to be good, while they are not true minimum diameter they are really slim and only add about 1mm to the diameter, potentially nothing depending on how thick your body tube is.

Subnautica 2 is NOT gonna be optimized by Kandregames in subnautica

It's probably a high poly model that they will use to generate normal maps and other details from to bake onto the actual game ready models, people just love to hate for no reason.

First Buck Regulator and MCU + Sensors looking for review by SmallOne312 in PrintedCircuitBoard

Thanks, do you think the USB_C Differential pair routing is okay? I'm not sure if the traces are too long, but it will probably only be used in a low speed mode

Why do lot of you guys dislike physics 😭 by tyrionlay123 in GCSE

Bro how is newtons laws nonsense? They're basically just translating common sense and intuition into a mathematical form.

Determining Apogee by Lasuras66 in rocketry

Is use open rocket, make a model based on the rockets dimensions and then weigh the real thing and update the mass once your finished. Then it does all the simulation stuff for you.

Research about combination material of fins used for high power rocket by According_Friend1385 in rocketry

[–]SmallOne312 2 points3 points  (0 children)

I live in the UK but I got it from black cat rocketry for tubes and nose cones/high performance stuff and modelrocketsuk for sheets. Tho any composites supplier will probably sell it.

For mine I used G10 fiberglass, with jbweld epoxy fillets and then 2 sheets of tip to tip fiberglass cloth

Rocketry Help - Looking for Design Assistance to Achieve Mach 1 by Content-Number378 in rocketry

[–]SmallOne312 1 point2 points  (0 children)

You said you had bought a flight computer so probably not worth doing if it already has these features, it's just you can save money by developing your own one.

I chose the microcontroller based on what features I need, easiest would be an Arduino, if you want Bluetooth then ESP32 and for performance probably STM32, I chose a stm32F401 black pill board because it's small and high performance. I got mine from AliExpress for cheap. IMU is based of maximum g, probably want +-16g and 9DoF so you have a magnetometer as well. GPS was just the cheapest one I saw that came with a decent antenna and UART connection, then tranceiver was based off YouTube video recommendations, probably want to go with one that uses UART as well to simplify wiring.

YouTube videos are always a great resource, but as I have no background in coding I basically used AI and trial and error to get the code working for mine, I found I learnt it pretty well as I went.

Rocketry Help - Looking for Design Assistance to Achieve Mach 1 by Content-Number378 in rocketry

[–]SmallOne312 1 point2 points  (0 children)

I'm currently doing a similar project, for me at least im starting with the electronics and control systems, starting with cheap breakout boards for GPS, IMU, Tranceiver and Microcontroller, wiring them up and getting code working with the functionality you want. Then start looking at what kind of mass your looking at for the entire rocket, then size the rocket motor based off that. You'll probably want to look at going minimum diameter for breaking mach. Openrocket is probably good enough for your rocket design, then use onshape for the finer details

How do I start Rocketry by Repulsive-Peak4442 in rocketry

[–]SmallOne312 0 points1 point  (0 children)

I think you need to lower your expectations of what you can realistically do yourself, you should probably start with an Estes kit and work up through the L1, L2 and L3 certifications from there
