www.3dsystems.com A European Union (EU) Horizon 2020 project called “SMall Innovative Launcher for Europe” (also known as the SMILE Project) aims to design a small satellite launch vehicle to deliver small satellites (up to 150 kg) into a 500 km sun-synchronous orbit. The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt, or DLR) Institute of Structures and Design, based in Stuttgart, Germany, is one of fourteen participating organizations, and is responsible for developing a liquid/liquid rocket engine injector for the SMILE Project launcher. The Institute’s focus on a liquid propulsion system is due to the potential for system refurbishment and reuse, therefore offering a more cost-efficient solution for small satellite launchers. In light of the high complexi
