Launch Campaign of the DECAN Lower Stage and Development Progress of a 3D-Printed Experimental Rocket at TU Berlin.

This paper describes the current development status of the DECAN rocket project at the Technische Universitat Berlin. The hot water powered first stage of the rocket, the solid propellant powered, and the 3D-printed upper stage are presented. The two-stage sounding rocket project offers the students involved the ability to work on a hands-on project in various engineering fields. In March 2017, the engineering qualification model of the DECAN lower-stage was launched as a single-stage rocket from a Bundeswehr test range, near Berlin, in Germany. The launch campaign will be described in this document. Moreover, the development of a 3D-printed experimental rocket structure, which is part of the DECAN rockets new features, will be presented. The design of the 3D-printed rocket structure is based on the flight proven DECAN-SHARK rocket.
