Microgravity eases several constraints limiting experiments with ultracold and condensed atoms on ground. It enables extended times of flight without suspension eliminates the gravitational sag for trapped atoms. These advantages motivated numerous initiatives to adapt operate experimental setups microgravity platforms. We describe design payload, motivations choices, capabilities Bose-Einstein Condensate Cold Atom Laboratory (BECCAL), a NASA-DLR collaboration. BECCAL builds heritage...

JAXA, CNES and DLR have decided to join their force develop fly a scaled reusable VTVL rocket stage called CALLISTO (Cooperative Action Leading Launcher Innovation in Stage Toss - back Operations). This vehicle will pave the way for future launch vehicles. One of its main goals is demonstrate mastering key techniques technologies that be needed later by operational Indeed frame numerous challenging are being matured specific case The challenges selection developed discussed solutions...
Carbon nanotubes (CNTs) are a promising material for novel sensor and interconnect applications. In both cases, the device performance depends strongly on electronic properties of tubes. Methods tuning structure especially band gap highly desirable. A computational study cobalt decorated CNTs, by means density functional theory, reveals that very few atoms can have significant impact structure, turning semiconducting CNTs into metallic state. This is further verified quantum transport...
Abstract The precise and realistic simulation of the vibration heating behaviour thermoplastics in ultrasonic welding process has so far been associated with great challenges. In particular, determination required frequency- temperature-dependent mechanical stiffness damping properties high-frequency range is only insufficiently possible according to current state art, which prevents an early valid numerical prediction weldability development new joining components. order provide more input...
This paper gives an overview of the proposed GNC architecture for DLR's Reusability Flight Experiment (ReFEx), which is split into two main subsystems: The Guidance and Control (G&C) subsystem, determines desired trajectory from current flight state to a designated target issues necessary commands actuators (canards rudder, as well reaction control system phases outside atmosphere) by calculating forces torques based on required changes velocity attitude following this trajectory; Hybrid...
This paper focuses on the preliminary design of Hybrid Navigation System (HNS) in development for CALLISTO vehicle. The requirements and boundary conditions derived from mission are briefly introduced their impact navigation is discussed. Subsequently, baseline architecture HNS including considerations its sensor suite will be presented. features an approach that overcomes limitations conventional based purely inertial solutions by fusion measurements different sensors. In order to satisfy...
