In the previous post you read on our website you will have been able to see that the last tests at the TNO laboratory a few weeks ago did not end so well for our hybrid rocket engine (article). Just like the last tests in May the combustion chamber failed a few seconds into the…

The decision has been made; Stratos II will fly on a hybrid rocket engine. A full scale one-stage hybrid engine using nitrous oxide as oxidizer and as a fuel sorbitol with a number of additives will be used to carry the payloads on board of the rocket to the 50km mark. The decision…

After the successful tests of 16th to 18th of August, it was decided to fire the PTDs (Pressure test devices) just once more, to gather more data points. This was done on Thursday, September 1st. We assembled two core-burning PTDs, with nozzles of 4.1 mm and 5 mm respectively, to obtain Klemmung values of 325…

In December 2010, it was announced by the Stratos II project team that the deadline for the proof-of-concept for the two competing propulsion teams (Solid and Hybrid) will be in June. By the June launch day, the teams should demonstrate their capability of producing a propulsion system that could take Stratos II to its goal…

Today the solid propulsion group performed a second successful pressurized propellant test. The aim of this test is to determine crucial performance parameters of the Alan-5 propellant in order to be able to design a motor around it and to get it UN-certified. After the propellant is certified, it will be possible to produce it…
