As mentioned in the last update of the Solid Six, we are confident that our new propellant, ALAN-7, is ready for use in a real rocket motor. And that is exactly what we are going to do in the coming weeks! During the last months, we have been working on the design and production of…

Even though the average temperature outside was far below the freezing point the Dawn team of DARE pushed on with the planned igniter test last Tuesday the 7th of February. This was needed as since the recent project, which was part of the Spacecraft Engineering Minor of the TU Delft, it was found that the…

In the past few months the hybrid propulsion group has been working along with other fellow students in a minor at the TU Delft. A minor is a semester during which students can choose to specialize in a field or discover new areas non-related to their field of study. The minor not only allowed more…

Today, the solid propulsion group performed their last tests using Pressure Test Devices (PTD). Although there were some problems with the data logger, we may call them a success (see DARE’s youtube channel: lrdare). The ignition was good, and the burns were very powerful. During the second test, we reached a chamber pressure of 75…

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…

Last Friday, the 20th of May, the hybrid propulsion group had three successful system tests of the hybrid propulsion system under development for Stratos II. The test engine had been redesigned to overcome leakage problems experienced with the previous generation of test motors. The first test using a conventional axial oxidizer injector system ignited successfully…

By Hein Olthof (only uploaded by Frank) On Friday, May 13th 2011, the solid propulsion group reached a great milestone at ASK ‘t Harde: the first rocket powered by an ammonium nitrate rocket propellant was successfully launched. After a year of thorough theoretical studies and testing, it is now proved that the newly designed ALAN-7…

We are tired, but satisfied enjoying our pizza and beer. We are processing the video footage and are almost ready to upload. At 22:30 we are going to watch “Hart van Nederland” which is a national television program. They joined us almost the whole day and made an item about the launch. So the story…

The end of Tuesday. There were two main themes today. Finalizing the concept launcher and the TU Delft press release. So first what did we do with the concept launcher? We put 6 kg of lead in the capsule, so instead of 9 kg it weighs 15 kg right now. Normally you take such drastic…

Traditionally every mission to space has a mission patch: a unique badge that is representative of the mission. Such a badge can function as a logo of the mission and is usually worn on team clothing. Stratos II can of course not stay behind in that respect. Therefore we designed a patch, which every team…
