Making Carbon Composite Tanks!
Both Tanks we build so far are made out of carbon and glass fibre composite with an epoxy matrix. The tanks consist of an inner composite liner, two composite bulkheads with a threaded aluminium adapter embedded, and a composite sleeve over the whole thing.We used a 6K 70mm carbon fibre sleeve and an 80g/m2 plain …
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, …
FAR Software: Telemetry, LoadCells and more
Hey everyone, it took us a long time to get started, but finally after Finn and I wrote our last exam for this semester, we finalized the partslist and got to work. As a short recap: The first step in Project Poseidon is FAR – the Fixed Airframe Rocket. Contrary to what the name suggests, …
FAR Block 1
Hey everyone, welcome to this small update regarding the FAR teststand. Our main objectives with FAR are the following: Verify with actual test data that the Poseidon Rocket is feasible. This boils down to that the thrust to weight ratio (TWR) of the rocket is greater than 1. Compare measured thrust, massflow and pressure in …
Water Rockets for beginners
Hey everyone, our goal with Project Poseidon is to develop an advanced waterrocket. Before we start with such an ambitious project, it is very important to actually understand the key physical principles behind waterrockets in general. We want to achieve that with the next three blog articles: This one will cover the basics. The second …
Start of the INS-Development
Hey everyone, currently the whole world is affected by SARS-CoV-2 and the resulting measures and so are we. We planned to shoot and edit our first video right around now, but these plans fell through as announced on the Studio blog. To make the most of it, we decided to start with the development of …
First video coming soon!
Introduction Video on our youtube channel. Starting in a few days, we are going to upload videos to our youtube channel in more or less regular intervalls.
