For the latest updates on the propulsion test campaign at TNO, click here. Today the hybrid propulsion team “Dawn” was awarded the TU Delft Universiteitsfonds teamwork prize for their work and progress over the past three years. After three teams, including Dawn, gave a the presentation this afternoon to a jury and audience, they…

On Friday the 1st of March the Hybrid team performed a test of their recently produced tank at Advanced Lightweight Engineering in Delft. The aluminium tank was a shortened version of the one that will be produced for the eventual engine. However, although this test tank is only approximately 1.5m in length compared to the 4m…

During the long weekend over Ascension Day (17 – 20 may) the hybrid propulsion team (Project Dawn) successfully launched “Morning Star”, the first ever hybrid-propelled rocket within DARE at the Model Rocket Flight Days (RJD 2012) in Roitzschjora, Germany. This technology demonstration flight marks a milestone for project Dawn and was the final step in…

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…

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…
