The objective of the project COTECH is to investigate new approaches of -manufacturing based on advanced technology convergence processes and to propose hybrid solutions for high added value cost effective -manufacturing emerging applications. The main goals of COTECH are to develop: (1) -replication technologies underpinned by emerging tool-making technologies for processing multi-material components and creating: a) 3D -components using high throughput multi-material -injection moulding with sub-m resolution; b) 2D -components using direct multi-material hot or UV embossing with a sub-200nm resolution. (2) Radically new replication convergent technologies combining the capabilities of -injection or embossing to a complementary activation step to create intelligent devices in a single process step: a) Hybrid processes based on -injection moulding using modules of e.g coating and compression injection moulding, to provide functionality to -devices, such as active coatings and combination of micro and nano features in a single step; b) Ultimately the hybrid processes based on -injection with embossing will be validated. This will offer a very high throughput multimaterial -injection that will enable the fabrication of 3D high aspect ratio -parts, complemented by an embossing step to allow ultra precise 2D features. (3) Global process chains with increased MTBF (50%) and fabrication of high quality products. This requires innovative non-destructive inspection solutions and simulation models. (4) High added value -devices with advanced functionalities. COTECH proposes to validate industrially the new technology convergence processes with 8 demonstrators representing the most emergent industrial sectors (transport, biomedical, energy). The expected market for the industry exceeds 1 Billion . COTECH will also address the problem of knowledge fragmentation by activating a polymer -manufacturing sub-platform as support to MINAM.

The land surface is a decisive factor regarding the state of the environment and human well-being. To manage it well, regularly obtained up do date information on land use and land cover is needed. Land monitoring provides this information through thematic maps based on the interpretation of areal photography, satellite imagery and further sources. These maps aid spatial planning, nature protection, agricultural policy, forestry, water catchment area management, etc. In spite of its importance, land monitoring in Europe is quite inefficient owing to lacking coordination between the national, sub-national, and European levels. Efforts are duplicated and given opportunities for mutual support are not utilised which means a substantial waste of resources. HELM is a network of authorities concerned with land monitoring across Europe. It will initiate a move to increase the maturity of European land monitoring along five sequential steps: (1) mutual interest in achieving reciprocal knowledge, (2) shared visions and planning for the future, (3) joint activities by taking on tasks collectively, (4) alignment of national systems involving the mutual adaptation of data interpretation methods and of the timing of data gathering, (5) lasting integration and combining data across all administrative levels. HELM envisions a coherent European land monitoring system characterised by high quality data and efficient productivity. This system will combine the broad range of specific expertise and resources of relevant authorities in the member states. Their work will be supported through targeted centrally supplied measures fulfilling common requirements for raw data and data processing. Through a continuous flow of knowledge from the local to the European scale and the other way round, future information needs regarding land use and land cover will be met as an essential basis for managing the land surface in the framework of European sustainable development.

The overall objective of the REProMag project is to develop and validate an innovative, resource-efficient manufacturing route (SDS process) for Rare Earth magnets that allows for the economically efficient production of net-shape magnetic parts with complex structures and geometries, while being 100% waste-free along the whole manufacturing chain. The new Shaping, Debinding and Sintering (SDS) process for Rare Earth magnets is an innovative automated manufacturing route to realise complex 3D- and multilayered parts; resulting in a significant increase in the material efficiency of at least 30% during manufacturing; while at the same time allowing additional geometrical features such as threads, cooling channels, small laminations/segments (e.g. to increase the efficiency of electrical motors) and structural optimisations such as lightweight-structures or the joint-free realisation. As part of the project, the possibility to produce hybrid parts such as an improved moving-coil transducer for headphones, loudspeakers and microphones will be evaluated. The SDS process allows a new level of sustainability in production, as the energy efficiency along the whole manufacturing chain can be increased by more than 30% when compared to conventional production routes. Moreover, the used raw material is 100% recycled and can be again recycled in the same way at the end of the lifetime of the products. In short, the innovative REProMag SDS process has the potential to manufacture complex structures of high quality and productivity with minimum use of material and energy, resulting in significant economic advantages compared to conventional manufacturing. The REProMag project is a highly innovative combination of applied research, technology development and integration, resulting in small-scale prototypes and a closely connected demonstration activity clearly showing the technical feasibility of the REProMag SDS processing route in a near to operational environment.

Hydrogen peroxide is under investigation with regard to its potential to replace the presently used highly toxic rocket propellants NTO and MON-3. Catalytically decomposed hydrogen peroxide results in a steam-oxygen mixture at elevated temperature and can be used either as a monopropellant or as an oxidizer in a bipropellant system. To guide the monolith catalyst design, a lumped parameter model of the decomposition implemented into a numerical thermal model has been developed. The one dimensional flow model includes decomposition and is coupled to a finite element structural domain of the decomposition chamber and catalyst to investigate the impact of the catalyst and the chamber structure on the decomposition behavior. Special focus is laid on the transitional behavior of hydrogen peroxide conversion to facilitate immediate start-up of the thruster system after valve opening command. The numerical results have been validated with experimental data. Major findings of the model such as the existence of a radial temperature gradient across the catalyst have been experimentally validated. The presented theoretical method predicted a strong impact of structural mass capacities of catalyst and decomposition chamber on the transient decomposition performance. This prediction has shown to be in good correlation with the experimental results. © 2012 The Institution of Chemical Engineers.

Transient mass fluctuations are predicted by Woodward in accelerated bodies which are subjected to a change of their internal energy. This sort of effects goes under the name of Mach effects. Proving their existence would lead to a relatively fast development of rapid space transportation systems. Several tests have been pursued by Woodward himself and others, the results being sometimes elusive and contrasting. The potential of this research field, however, justifies further investigation. Until now, the tests have been conducted using exclusively capacitors as means of energy storage, and the acceleration has been supplied by the Lorentz force or by a piezoelectric actuator. The present work explores the possibility to search for Mach effects in bodies subjected to impulsive forces caused by a nonuniform magnetic field. Such magnetic field would provide both the acceleration and the change in the internal energy of the body, required for the expression of Mach effects. It will be shown that an impulsive (bell shaped) force applied to a special sort of test body should produce an anomalous final speed of the body itself. A qualitative analysis is presented and a possible experimental setup is outlined. ©2011 Published by Elsevier B.V.

The mission complexity of Nanosatellites has increased tremendously in recent years, but their mission range is limited due to the lack of an active orbit control or δv capability. Pulsed Plasma Thrusters (PPT), featuring structural simplicity and very low power consumption are a prime candidate for such applications. However, the required miniaturization of standard PPTs and the adaption to the low power consumption is not straightforward. Most investigated systems have failed to show the required lifetime. The present coaxial design has shown a lifetime of up to 1 million discharges at discharge energies of 1.8 J in previous studies. The present paper focuses on performance characterizations of this design. For this purpose direct thrust measurements with a μN thrust balance were conducted. Thrust measurements in conjunction with mass bit determination allowed a comprehensive assessment. Based on those measurements the present μPPT has a total impulses capability of approximately I≈1.7 Ns, an average mass bit of 0.37 μg s-1 and an average specific impulse of Isp≈904 s. All tests have shown very good EM compatibility of the PPT with the electronics of the flight-like printed circuit board. Consequently, a complete μPPT unit can provide a δv change of 5.1 m/s or 2.6 m/s to a standard 1-unit or 2-unit CubeSat respectively. © 2013 IAA.

A study was conducted, which focused on the investigation of a bipropellant thruster system suitable for the increasing market of small satellites with a nominal thrust of 1 N. The nominal thrust corresponded to mass flow rates of ̃0.32 and ̃0.043 g/s for hydrogen peroxide and kerosene mass flow rates. The thruster setup used for this activity was an actively cooled thruster module incorporating a combustion chamber and a decomposition chamber. The cooling of the combustion chamber was achieved by a gaseous N2 flow guided along the external walls of the combustion chamber. The oxidizer and fuel feed systems were equipped with pressure gauges recording tank and feedline pressures. Oxidizer mass flowrate was determined using a mass flow meter, employing a measurement principle based on Coriolis force independent from fluid density and hydrogen peroxide concentration.

Space activities and applications play an important role in strengthening the competitiveness of Europe by scientific progress in the knowledge-based society, and by providing strategic influence and security. Major successful space missions under European leadership have placed ESA and its Member States, the European science community at the forefront. To continue this path Europe must have independent and competitive access to space. With the ITAR (International Traffic in Arms Regulations) continuing to impede the acquisition of US components, Europe thus needs to develop an assured independent source of propulsion components. Today space craft propulsion relies heavily on toxic and carcinogenic hydrazines as propellants. Hydrazine itself is widely used as monopropellant and MMH and UDMH is used as bipropellant fuel. These propellants are a threat to people and the environment, and handling these toxic propellants impedes costly safety measurers. As new ideas and new technologies emerged in the last years, and as the concerns about both the environment and the handling of carcinogenic propellants significantly increase, the so-called Green Propellants show potential improvements with respect to performance and cost. The goal of this project is thus to select the most promising green liquid propellant candidate/s and to push the propulsion technology to the level needed to prove that Green Propellant technology is feasible and competitive. Research and development on Green Propellants and adjacent propulsion technology in Europe is geographically fragmented and insufficiently funded. With the present consortium, some of the key-players in Europe will harmonize their capabilities to meet this demanding goal.

The project deals with the replacement of hydrazine within space propulsion systems. It improves significantly the ADN-based propellants currently existing and enables the replacement of hydrazine within the whole operational area of currently used hydrazine propulsion systems. The objectives of the project are: 1.) Replacing hydrazine by adapting the propellant to currently existing materials available in Europe 2.) Development of a cold-start capable ignition system to replace hydrazine in the whole operational area 3.) Verification of the technology within battleship unit(s) to reach a Technology Readiness Level of 5 4.) Adapted numerical models to describe the processes within such propulsion systems. To reach these objectives, the following development will be done within the project A) Propellant development in order to obtain maximal temperatures within the combustion chamber that can be withstand with currently available materials in Europe. Additionally, the propellant will have increased specific impulses in relation to hydrazine. B) Development of catalytic ignition systems to withstand the thermal and mechanical shocks while having cold-start capability C) Design and testing of the corresponding battleship units within the project to verify the achievement of the project experimentally (reach TRL of 5) D) Generating validation results for future purposes to adapt the technology to future purposes. Therefore, the relation to the work programme Alternative to hydrazine in Europe is achieved by a replacement of the currently hydrazine based propulsion system with a green propellant system with higher specific impulse.
