Avionics Schematics and Layout

Moving from FAR to GAP, we’re building a whole (almost flight worthy) rocket. This includes the corresponding Avionics, which we will look at in more detail here. This first version of the avionics PCB should function as a trial and guide for subsequent flight-ready boards. Accordingly, it should have equivalent or at least similar components …

Machining fittings for Poseidon!

We machined the fittings for the poseidon water rocket in the student workshop of our university. After turning the two fittings in a lathe, boring the axial holes and cutting the axial theads, we milled the sides and drilled the radial holes. The left fitting connects the main valve (inner thread, G1/4) to the water …

FAR High Pressure Tests

Over the summer we tested the FAR prototype under higher pressure. For that purpose we bought a 300bar air cylinder and regulator.We conducted the high pressure tests to research thrust and burntime under flying pressures of about 30bar and to check the experimental data against our simulation. Hydrostatic tests At first, to verify that the …

Machining parts for test tanks

Before we build the flight-ready tanks for the Poseidon Rocket, we’re going to manufacture test tanks to see how they’re going to perform and hold up to the expected pressures.You can find the concept and design of these tanks in a previous article: Poseidon Tanks: Concept and Design. As discussed previously, the tanks must have …

Poseidon Tanks: Concept and Design

FAR so far The FAR test platform has tanks made out of PVC. We chose this material because it’s quick and easy to build a tank out of, and can sustain a pressure of about 8 bar. Additionally, it is relatively cheap and available. However, these PVC tanks are not flight ready. They weigh almost …

Thrust and Valve Fundamentals

Hey there! Right now, we are in the beginning of development and have to test the basic concepts first, so take this following stuff with a grain of salt. As for the mechanics, this means things like tank and valve fundamentals. Because we want to have the capability to control the thrust of the rocket, …
