We passed the IPR! Yay!

Hej peeps!

Today, there is a different kind of blogpost - less text, more pictures. Last week was quite busy for the BESPIN team, that's also the reason for this belated post. The IPR was on Wednesday last week and also the university hosted a big even including company and institute presentations and a job fair. Additionally, Stefan Krämer visited us to check on how our project is looking and how far we got with ordering, assembling and testing of the different components and subsystems. We even could to show something to him! Well, at least the electrical and software division... Mechanical is still waiting for the ordered parts to arrive but some stuff already got shipped to us.
Okay, enough talking. Let's continue with some visual impressions from last week
 
 
 
Electrical division is super proud to present a working camera. Two of those cameras will be attached to the baseplate of the experiment to monitor the inflation and deployment of the parachute. Another one is pointed at the horizon to investigate the attitude.
 
 
Oskar is presenting the mechanical design during the IPR presentation. Stefan seems to be quite pleased...
 
 
...at least he seems to be more pleased than Anna. Her concerned face is just saying "please don't f*** it up".
 
 
 
But Oskar is doing a great job, so no worries.
 
 

The rainbow engineer in his element, presenting FEA slides to Stefan.

Even Diyar is interested in the IPR.
 
The job fair at our university. ESA, SSC, IRF and LKAB are represented. In the lower left, the SpaceBall can be seen, a contraption to simulate weightlessness-like feelings just like real astronauts experience. Or you simply get dizzy.
 
 
Presentation about the IRF in our Auditorium.
 
 
Stefan is judging our mechanical components while electrical is working feverishly to get circuits running (lower right). Even though nothing really works, Stefan will still give us a pass of the IPR. Yippie.
 
 
Oskar became father! Oh, it's a Teflon. 25kg of Teflon. It will be used to mill out three nosecones. One for the drop test and two for the actual experiment assembly.
 
 
The parachutes we will use for the experiment finally arrived - very exciting! This one is the main parachute which will be deployed by the drouge parachute at 3km altitude to break down the experiment to a temrinal velocity of 6m/s. It's diameter is about 1.5m.
 

Diyar explains to us how parachutes work and how they need to be packed. The packing is actually quite important. If the deployment goes wrong and e.g. all the forces act only on one of these tiny white nylon strings, the parachute will rip. Proper packing and the use of a slider ring can prevent that. We hope it works.



 
Actually, Diyar also doesn't have a clue about the packing.
 
 
The drogue parachute. No, not Anna... the thing on her head. It is quite small and doesn't produce any drag if you just hold it into the wind. But since it will be deployed at 105m/s (to break down to 40/ms), it will provide quite a lot of force (1000N) to deploy the main parachute.
 
 
At some point we needed a rest and fortunately Nik prepared a cake (not depicted in the picture). Thank you Nik! Helps the motivation of the group as you can see on Oskars finger.
 

Sometimes you deserve another break - I mean, look at John. Also, Oskar.exe has stopped working.



That was it so far, I hope you enjoyed the pictures. Stay tuned.
Fabs out. Zoop.
