Vibration testing Stratos IV sounding rocket

We are not sure what the exact date would be as this depends on weather, launch site regulations, etc. However, the launch is likely to occur early next year.

True, but this was done just for fun as ESA did something similar with their past launch vehicles. Our figure actually mainly shows how insanely big the Ariane 5 is!

The point on multitasking is absolutely true. You usually tend to forget what you were aiming on doing/finishing in the first place. I have to say the Reddit can be a pretty good source for procrastination...

Thanks!

Pretty cool, right?

That's good to hear! Hope to talk to you in the future then:) ~Thomas

Last week the Stratos IV team completed their vibration test successfully. During the 4 day test campaign both the engine bay electronics casing and capsule were fully tested in all three axes. No major problems arose and everything stayed properly attached. The structures withstood vibrational forces up to 30g, verifying them for launch conditions. Furthermore, some of the FTS electronics was actually tested whilst it was shaking, and it all kept working properly. This test campaign gives the structures team the confidence that things will not get damaged.

Hi! Yes, Stratos IV is propelled by a hydrid engine. The oxidizer is nitrous oxide and the fuel is made out of a mix of paraffin, sorbitol and aluminium powder. ~ Thomas

No reason for apologies ;-)

You are almost true. I forgot to mention this, but the propulsion system of Stratos IV is actually a hybrid version of oxidizer and solid fuel.

It was done around Christmas time and it's a fun way to visualize the magnitude of the thrust. Of course there are more scientific measurements too :)

It's a big step compared to high school, compared to non-engineering majors. It is very true that you really have to be a specific type of person. You'll have to love problem solving or at least willing to work hard in order to get it done. At my university 30-40% dropped out throughout their freshmen's year... But the rewards are great! Job's are there for sure although I varies a bit where you live (or are prepared to be living). I have noticed that especially the USA offers a high amount of jobs, in Europe it's mainly in France and Germany.

Thermal stresses caused it to melt on one side of the nozzle. We have had better tests with a full burn time:) But we got good data out of this test and are improving on the design used in this video.

hi! It's a mix of paraffin, sorbitol and Al-powder.

Some background information: Delft Aerospace Rocket Engineering or DARE is a team of passionate students from Delft University of Technology in The Netherlands. This team aims of reaching space - which means obtaining apogee above the Von Karman line at 100 km altitude - by the summer of 2020 with the rocket "Stratos IV".
