Rolls-Royce obtains final approval for acquisition of ITP


Thursday, 7 December 2017

Rolls-Royce has obtained the approval of all the relevant authorities for the acquisition of the outstanding 53.1% shareholding in Industria de Turbo Propulsores SA ("ITP") owned by SENER Grupo de Ingeniería SA ("SENER"). Approval from the authorities in Spain paves the way for Rolls-Royce to conclude the acquisition, which was originally announced on 11 July 2016.

On 28 November 2016, Rolls-Royce confirmed the valuation of EUR 720m for the 53.1% shareholding, following due diligence. Consideration will be settled over a two-year period following completion in eight evenly spaced instalments of equal value. The agreement with SENER allows flexibility to settle each tranche of the consideration either in cash or in the form of Rolls-Royce shares as preferred by Rolls-Royce.

Completion is expected before the end of 2017. The first payment will be made 16 business days post-closing in early 2018 and the consideration will be in the form of shares. The decision on the form of subsequent payments will be determined as each individual payment falls due.

SMILE project: First hot firing tests of LOX/kerosene rocket engine with 3D-printed injector

DLR press release


Within the SMILE project, first hot firing tests were successfully conducted in early November 2017. The measured data shows very good mixing and combustion efficiencies of the printed injector in combination with a water-cooled, metallic combustion chamber. The SMILE project aims to design a cost-effective launch vehicle for the delivery of small satellites into sun-synchronous orbits (SSO). In order to fulfil commercial, operational and technical requirements, multi-disciplinary design optimisation processes are applied.

DLR’s Institute of Structures and Design is responsible for developing a reusable liquid rocket engine. The design is thereby based on ceramic engine components which are specifically qualified due to their high thermal shock resistance and high-temperature applicability. Thus, innovative design methods become possible allowing such systems to be reused. Furthermore, advanced manufacturing technologies are used for the highly complex injector head component designed by DLR. Partner 3D Systems printed the prototype injector for LOX/kerosene operation via additive layer manufacturing on a ‘ProX DMP 320 metal printer’ at its manufacturing site in Belgium.

For experimental testing, DLR provided an integrated setup. Partner PLD Space set up and operated a high-pressure rocket engine test bench in Teruel, Spain.



Next steps within the SMILE liquid rocket engine development focus to replace metallic wall structures of the combustion chamber by fibre-reinforced, ceramic materials as intended. Further goals are to optimise both the injection and ignition system as well as to improve the overall engine design.

This work is performed within the ‘SMall Innovative Launcher for Europe’ project. SMILE, coordinated by NLR, has received funding from the European Union’s ‘Horizon 2020 research and innovation program’ under grant agreement No 687242. Further info on SMILE can be found on www.small-launcher.eu.

Research Article:
Abstract Two limitations of additive manufacturing methods that arise from layer-based fabrication are slow speed and geometric constraints (which include poor surface quality). Both limitations are overcome in the work reported here, introducing a new volumetric additive fabrication paradigm that produces photopolymer structures with complex nonperiodic three-dimensional geometries on a time scale of seconds. We implement this approach using holographic patterning of light fields, demonstrate the fabrication of a variety of structures, and study the properties of the light patterns and photosensitive resins required for this fabrication approach. The results indicate that low-absorbing resins containing ~0.1% photoinitiator, illuminated at modest powers (~10 to 100 mW), may be successfully used to build full structures in ~1 to 10 s.

Lawrence Livermore Laboratory press release
https://www.llnl.gov/news/volumetric-3d-printing-builds-need-speed 
By using laser-generated, hologram-like 3D images flashed into photosensitive resin, researchers at Lawrence Livermore National Laboratory, along with academic collaborators, have discovered they can build complex 3D parts in a fraction of the time of traditional layer-by-layer printing. With this process, researchers have printed beams, planes, struts at arbitrary angles, lattices and complex and uniquely curved objects in a matter of seconds

While additive manufacturing (AM), commonly known as 3D printing, is enabling engineers and scientists to build parts in configurations and designs never before possible, the impact of the technology has been limited by layer-based printing methods, which can take up to hours or days to build three-dimensional parts, depending on their complexity.

However, by using laser-generated, hologram-like 3D images flashed into photosensitive resin, researchers at Lawrence Livermore National Laboratory (LLNL), along with collaborators at UC Berkeley (link is external), the University of Rochester (link is external) and the Massachusetts Institute of Technology (link is external) (MIT), have discovered they can build complex 3D parts in a fraction of the time of traditional layer-by-layer printing. The novel approach is called “volumetric” 3D printing, and is described in the journal Science Advances (link is external), published online Dec. 8.

“The fact that you can do fully 3D parts all in one step really does overcome an important problem in additive manufacturing,” said LLNL researcher Maxim Shusteff, the paper’s lead author. “We’re trying to print a 3D shape all at the same time. The real aim of this paper was to ask, 'Can we make arbitrary 3D shapes all at once, instead of putting the parts together gradually layer by layer?' It turns out we can.”

The way it works, Shusteff explained, is by overlapping three laser beams that define an object’s geometry from three different directions, creating a 3D image suspended in the vat of resin. The laser light, which is at a higher intensity where the beams intersect, is kept on for about 10 seconds, enough time to cure the part. The excess resin is drained out of the vat, and, seemingly like magic, researchers are left with a fully formed 3D part.
The approach, the scientists concluded, results in parts built many times faster than other polymer-based methods, and most, if not all, commercial AM methods used today. Due to its low cost, flexibility, speed and geometric versatility, the researchers expect the framework to open a major new direction of research in rapid 3D printing.

Volumetric 3D printing creates parts by overlapping three laser beams that define an object’s geometry from three different directions, creating a hologram-like 3D image suspended in the vat of resin. The laser light, which is at a higher intensity where the beams intersect, is kept on for about 10 seconds, enough time to cure the object.
“It’s a demonstration of what the next generation of additive manufacturing may be,” said LLNL engineer Chris Spadaccini, who heads Livermore Lab’s 3D printing effort. “Most 3D printing and additive manufacturing technologies consist of either a one-dimensional or two-dimensional unit operation. This moves fabrication to a fully 3D operation, which has not been done before. The potential impact on throughput could be enormous and if you can do it well, you can still have a lot of complexity.”

With this process, Shusteff and his team printed beams, planes, struts at arbitrary angles, lattices and complex and uniquely curved objects. While conventional 3D printing has difficulty with spanning structures that might sag without support, Shusteff said, volumetric printing has no such constraints; many curved surfaces can be produced without layering artifacts.

“This might be the only way to do AM that doesn’t require layering,” Shusteff said. “If you can get away from layering, you have a chance to get rid of ridges and directional properties. Because all features within the parts are formed at the same time, they don’t have surface issues.
“I’m hoping what this will do is inspire other researchers to find other ways to do this with other materials,” he added. “It would be a paradigm shift.”

Shusteff believes volumetric printing could be made even faster with a higher power light source. Extra-soft materials such as hydrogels could be wholly fabricated, he said, which would otherwise be damaged or destroyed by fluid motion. Volumetric 3D printing also is the only additive manufacturing technique that works better in zero gravity, he said, expanding the possibility of space-based production.

The technique does have limitations, researchers said. Because each beam propagates through space without changing, there are restrictions on part resolution and on the kinds of geometries that can be formed. Extremely complex structures would require lots of intersecting laser beams and would limit the process, they explained.

Spadaccini added that additional polymer chemistry and engineering also would be needed to improve the resin properties and fine tune them to make better structures.

“If you leave the light on too long it will start to cure everywhere, so there’s a timing game,” Spadaccini said. “A lot of the science and engineering is figuring out how long you can keep it on and at what intensity, and how that couples with the chemistry.”

The work received Laboratory Directed Research and Development (LDRD) program funding. Additional LLNL researchers who contributed to the project were Todd Weisgraber and Robert Panas, Lawrence Graduate Scholar and University of Rochester Ph.D. student Allison Browar, UC Berkeley graduate students Brett Kelly and Johannes Henriksson, along with Nicholas Fang at MIT.
