The possibility of replacing presently used highly toxic propellants by so-called Green Propellants has captured the attention of research groups as well as of the relevant industry worldwide. And indeed the potential of Green Propellants seems inspiring. The lower level of toxicity reduces the risk for personnel handling such propellants and therefore allows simplified and more cost efficient handling procedures. A variety of authors have outlined other areas of possible cost reduction when using propellants with a lower toxicity level. This includes a simplification of the propellant logistic and storage, fueling infrastructures at the launch pads, and propellant procurement to name only some. Most authors have focused on one particular Green Propellant in their experimental work and outlined the characteristics and benefits of it. Although very promising results have been reported, Green Propellants in general have up to now failed to generate a confidence level sufficient for the major industry to initiate first steps to implement them into a commercially available propulsion system. Contributing to this hesitation is the lack of a comprehensive effort to investigate Green Propellants and to provide industry with information they can use to re-evaluate their future strategy in respect to Green Propellants. For this reason a European consortium, financed by the European Commission in the 7th Framework Program (FP7) and consisting of 11 entities from 7 European countries, was established. The project, "Green Advanced Space Propulsion" (GRASP) aspires to provide such an information background. In the first phase of the project, GRASP has compiled a data base of more than 100 Green Propellant. This data base contains physical properties as well as information with regard to the individual toxicity levels and performance data. Based on this data base a preliminary selection was conducted to identify the most promising Green Propellant candidates. In the present phase of the project those candidate propellants are experimentally investigated to further down-select the candidates. The present paper provides an overview of the GRASP activities and discusses the selection process and the GRASP objectives in general and test goals obtained up to now in particular. © 2011 by Carsten Scharlemann.

Tuned liquid column gas damper (TLCGD) show excellent vibration absorbing capabilities appropriate for applications in wind- and earthquake engineering. However, in the early regime of strong motion seismic excitation or to counteract strong wind gusts the performance of the passive device can be increased substantially by active elements obtained from adding a pressurized gas supply with input-output valves to the sealed ends of the TLCGD. To prove the working principle of active TLCGD several small scale laboratory experiments have been performed with single and multiple degree of freedom host structures. To obtain a desired dynamic behavior, a conventional feedback control law is used to compute small active pressure inputs to the TLCGD. The experiments have proven that the active device is able to substantially reduce the dynamic system response in a broad frequency range. In fact, dangerous structural resonances of lightly damped structures can be avoided even if the passive absorber is not tuned perfectly. For multiple degree of freedom host structures a suitable control enables a single active TLCGD to counteract several modes of vibrations thereby avoiding the need to install numerous passive devices. © The Society for Experimental Mechanics, Inc. 2015.

In the proposed contribution the effect of the shear correction function is originally studied and evaluated in modal analysis of the functionally graded material (FGM) beams. Spatially continuous variations of the material properties are considered. The shear correction function is calculated from the shear strain energy equation including spatial Poisson′s ratio variations. The equations of the homogenized FGM beam free vibration and their solution is presented including the shear correction function. Four coupled differential equations are derived and used in the modal analysis of beams with polynomial continuous longitudinal and transversal variations of material properties. Further, 2nd order beam effects and longitudinal varying elastic beam foundations are considered. The influence of using an average shear correction factor is evaluated through numerical experiments. Additionally, the longitudinal eigenfrequencies are calculated. Continuum solutions using solid finite elements are taken as a reference for comparison purposes. © 2012 Elsevier Ltd.

In modern data acquisition a constantly growing number of applications using technically advanced image processing systems has been observed in recent years. The work presented proves, that it is possible to use standard webcams combined with an innovative lighting concept to precisely measure displacements of high frequency structural oscillations. By means of stroboscopic light, the actual frequency of a periodic high frequency oscillation is shifted to the low detection rate of the cameras applied. Object or surface deformations are measured and visualized by well-established 3D digital image correlation procedures. The excellent performance of the proposed system is confirmed by a wide range of experimental studies. All results indicate that this innovative system is a perfect supplement to traditional modal analysis measurement systems, particularly in the context of teaching vibrations. © The Society for Experimental Mechanics, Inc. 2016.

SEAL is a project for an integrated project consisting of 17 equipment assessment sub-projects in the area of semiconductor manufacturing equipment. The assessment themes are equally spread amongst processing and metrology equipment, heading beyond the current state-of-the-art both for More Moore and More than Moore applications. The strategic objective of SEAL is to effectively combine efforts, resources and expertise in the joint assessment of novel equipment supported by cross-cut R&D dedicated to the identified needs of the assessment sub-projects.For Lithography, the key areas of illumination systems for mask aligners, EUV mask manufacturing and intelligent overlay management are addressed as well as massively parallel e-beam lithography. In addition, three important processes are addressed: low temperature oxidation, cleaning of sensitive interconnect stacks/structures and ion implantation for ultra shallow junctions and defect engineering. For metrology and analysis, the main focus is on enabling innovative systems to efficiently contribute to at-line and in-line monitoring and control within semiconductor facilities. Without such equipment, it will not be possible to validate progressively advanced processes during development and manufacturing.Cross-cut R&D activities relating to all equipment assessment sub-projects are covered including APC, model based control, equipment simulation, enhanced wafer and equipment logistics, advanced communication and man machine-interfaces, and virtual equipment engineering. A common approach for the assessment activities will be utilised with specifications that will be refined for each equipment type for the progressively emerging technology nodes.Overall, SEAL will strengthen the European equipment manufacturing industry in an ideal and sustainable way by combining advanced R&D topics in equipment sub-projects involving a wide community of users, research institutes and equipment suppliers with many SMEs.
