The project HERCULES-2 is targeting at a fuel-flexible large marine engine, optimally adaptive to its operating environment. The objectives of the HERCULES-2 project are associated to 4 areas of engine integrated R&D: Improving fuel flexibility for seamless switching between different fuel types, including non-conventional fuels. Formulating new materials to support high temperature component applications. Developing adaptive control methodologies to retain performance over the powerplant lifetime. Achieving near-zero emissions, via combined integrated aftertreatment of exhaust gases. The HERCULES-2 is the next phase of the R&D programme HERCULES on large engine technologies, which was initiated in 2004 as a joint vision by the two major European engine manufacturer groups MAN and WARTSILA. Three consecutive projects namely HERCULES - A, -B, -C spanned the years 2004-2014. These three projects produced exceptional results and received worldwide acclaim. The targets of HERCULES-2 build upon and surpass the targets of the previous HERCULES projects, going beyond the limits set by the regulatory authorities. By combining cutting-edge technologies, the Project overall aims at significant fuel consumption and emission reduction targets using integrated solutions, which can quickly mature into commercially available products. Focusing on the applications, the project includes several full-scale prototypes and shipboard demonstrators. The project HERCULES-2 comprises 4 R&D Work Package Groups (WPG): - WPG I: Fuel flexible engine - WPG II: New Materials (Applications in engines) - WPG III: Adaptive Powerplant for Lifetime Performance - WPG IV: Near-Zero Emissions Engine The consortium comprises 32 partners of which 30% are Industrial and 70% are Universities / Research Institutes. The Budget share is 63% Industry and 37% Universities. The HERCULES-2 proposal covers with authority and in full the Work Programme scope B1 of MG.4.1-2014.

The world around us is full of modern technology designed to make our lives safer, more comfortable and more efficient. Such technology is made possible by materials and devices that are able to interact with their surrounding environment either by sensing or acting upon it. Examples of such devices include motion detectors, fuel injectors, engine sensors and medical diagnostic tools. These interactive devices contain functional materials that can pose health hazards, are obtained from parts of the world where supply cannot be guaranteed or are relatively scarce. If access to these functional materials is restricted, many of these advances will no longer be available resulting in a reduction in living standards and decreased UK economic growth. There already exist a number of replacement materials that can provide the same functions without the same levels of concerns around safety, security of supply and sustainability. However, these replacement materials need to be manufactured using different processes compared to existing materials. This project explores new manufacturing technologies that could be used to create interactive devices that contains less harmful and sustainable materials with a secure supply. This project will focus on two types of material - thermoelectric and piezoelectric - where the replacement materials share a set of common challenges: they need to be processed at elevated temperatures; they contain elements that evaporate at high temperatures (making high temperature processing and processing of small elements difficult); they are mechanically fragile making it difficult to shape the materials by cutting, grinding or polishing; they are chemically stable making it difficult to shape them by etching; and many are air and moisture sensitive. The proposed research will address these challenges through three parallel research streams that proactively engage with industry. The first stream is composed of six manufacturing capability projects designed to develop the core manufacturing capabilities and know-how to support the programme. The second is a series of short term feasibility studies, conducted in collaboration with industry, to explore novel manufacturing concepts and evaluate their potential opportunities. Finally, the third stream will deliver focussed industrially orientated projects designed to develop specific manufacturing techniques for in an industrial manufacturing environment. The six manufacturing capability projects will address: 1) The production of functional material powders, using wet and dry controlled atmosphere techniques, needed as feedstock in the manufacture of bulk and printed functional materials. 2) How to produce functional materials while maintaining the required chemistry and microstructure to ensure high performance. Spark Plasma Sintering will be used to directly heat the materials and accelerate fusion of the individual powder particles using an electric current. 3) Printing of functional material inks to build up active devices without the need to assemble individual components. Combing industrially relevant printing processes, such as screen printing, with controlled rapid temperature treatments will create novel print manufacturing techniques capable of handling the substitute materials. 4) How to join and coat these new functional materials so that they can be assembled into a device or protected from harsh environments when in use. 5) The fitness of substituted material to be compatible with existing shaping and treatment stages found later in the manufacturing chain. 6) The need to ensure that the substitute materials do not pose an equal or greater risk within the manufacturing and product life cycle environment. Here lessons learned from comparable material systems will be used to help predict potential risks and exposures.


A cutting tool includes a generally cylindrical tool body disposed about a central longitudinal axis, the tool body having first and second extending sides with respective first and second bores that pass therethrough, wherein a first longitudinal axis of the first bore and a second longitudinal axis of the second bore are configured to be non-parallel to a horizontal axis of the tool body that is perpendicular to the central longitudinal axis of the tool body. The cutting tool also includes a replaceable cutting insert configured to be removably attached to the tool body and first and second attachment elements configured for receipt in the first and second bores, respectively, and adapted to engage the cutting insert and secure the cutting insert to the tool body.

The invention relates to a tool head for a rotary tool. The tool head extends along, and rotates about, a rotational axis in a rotational direction during operation. The tool head is designed for replaceable fastening on a carrier shank of the rotary tool and comprises on the back thereof a coupling surface comprising a first serration having a plurality of ribs running parallel to one another and grooves running parallel to one another. The first serration comprises at least two part-serrations oriented toward one another in the rotational direction at an angle. Each part-serration having a plurality of ribs and grooves running parallel, for centering the tool head relative to the carrier shank. The invention furthermore relates to a rotary tool having such a tool head.
