Flash memory drives for aerospace, defence and industrial applications

New T5EN PCIe flash-based memory solution meets growing demand for NVMe flash-based solutions


MART Modular Technologies, a SMART Global Holdings, Inc. company announced the new T5EN PCIe/NVMe M.2 2280 and U.2 flash drives for aerospace, defence and industrial applications that require durable, rugged, and secure memory storage. Extending SMART Modular’s T5E family of SSDs, the T5EN offers capacities up to 8TB (M.2 up to 4TB) Gen3x4 performance using 3D TLC flash with pSLC support.

“With the growing trend toward NVMe in embedded systems, developing the T5EN was a natural progression and complement

to our existing product line,” explains Mike Guzzo, senior director of SMART Modular’s RUGGED line of Flash products. Guzzo adds, “Fundamentally, the T5EN includes all of the existing advantages of the T5E, such as very high capacity, superior reliability for harsh environmental extremes, military erase algorithm support, as well as 256 bit encryption. These advantages equate to a higher level of protection for mission- critical data and instill confidence in the overall reliability of the data storage devices that support high-performing NVMe architectures.” The M.2 module and U.2 drive both come in 3D triple-level cell (TLC) NAND and pseudo single-level cell (pSLC). Both versions feature AES-XTS 256-bit encryption, automatically protecting data written to the drive. Both

versions are also OPAL 2.0 compliant, which is yet another level of self-encryption that ensures the data on the SSDs is not capable of being accessed by unauthorised personnel. Manufacturing a durable and rugged SSD starts with the design. SMART Modular selectively sources all of its components and tests

them throughout the engineering development phase to ensure high reliability and performance. The design process also incorporates higher margins for routing of signals, thicker PCBs, and more durable enclosures. Adopting aerospace and wind energy technology S

ustainable Marine is adopting cutting-edge aerospace and wind energy technology in a new project to drive the evolution of tidal turbine foils (blades). The marine renewables specialist is leading the EvoFoil project in partnership with German organisations M&D Composites Technology and Leibniz Universität Hannover Institute of Production Engineering and Machine Tools. The EvoFoil project aims to deliver a series of design innovations to optimise the performance of tidal turbine foils while driving down production and operation costs. Sustainable Marine is receiving advisory services and up to $578,244 in research and development funding from the National Research Council of Canada Industrial Research Assistance Program (NRC IRAP) for the two-year project. Additionally, the German partners on this project are receiving funding support from the German Federal Ministry for Economic Affairs and Energy (BMWi) through the Central Innovation Programme for SMEs (ZIM). “The project will address key areas of the foil design including the tip geometry and the overall composition involving a new ‘multi-material’ concept. It will enable us to deliver an extensive field and lab testing campaign combining decades of knowledge and experience from across sectors to take our tidal foil technology to the next level,” says Ralf Starzmann, head of Power Systems at Sustainable Marine. “Our German partners bring strong expertise in their respective fields including world- class knowledge from the aerospace and wind energy sectors. We believe there are several key interventions which can be made to further optimise our foil performance and help drive evolution in the tidal energy market more broadly. These design factors will play an important role addressing areas such as

tidal turbine foils including thermal changes, corrosion and abrasion, adding to hydrodynamic loads during operation,” says M&D Composites Technology Managing Director Tim Markwald. “Our mission with the EvoFoil project is to drive innovation to work in harmony with these immense natural forces. This will involve the use of innovative manufacturing methodologies in order to reduce manufacturing costs. In addition, we are exploring different surface treatments to protect against erosion given the harsh environment of the Bay of Fundy.”

energy extraction, power curve deterioration and operating and maintenance costs. EvoFoil represents another important step to reduce Levelized Cost of Energy while reinforcing the stature of tidal power as a competitive future energy source.” Earlier in 2021, Sustainable Marine launched its new 420kW PLAT-I 6.40 floating tidal energy platform in the Bay of Fundy, Nova Scotia, Canada which will form part of the world’s first floating tidal energy array. The device is currently undergoing commissioning and testing in Grand Passage before its deployed to Fundy Ocean Research Centre for Energy (FORCE). The site experiences some of the most extreme tidal ranges in the world - with 115 billion tonnes of water surging in and an out, twice a day - creating a resource from which circa 7GW of power could be extracted.

“While offering tremendous natural power the Bay of Fundy also places a range of environmental conditions on the

“We are currently researching a new material concept to improve the mechanical behaviour of the foil and help counteract the various loads,” says Carsten Schmidt Leibniz Universität Hannover Head of Research Group High Performance Production of CFRP-Structures. “This ‘multi- layer’ concept is being influenced by studies on the current foil structure made of carbon fibre reinforced plastic and the scientific findings of the German Research Foundation “Multilayer-Insert” project. The innovation will enable the load carrying areas of the foil to be partially reinforced with thin metallic sheets, improving adaption to the turbine drive shaft boosting durability and strength. More intense work is now required to manage the increase in scale and geometrical complexity of the metallic inserts to accomplish a proper load transfer from the foils root to the turbine hub.” The news comes as German and Canadian Governments recently stepped-up efforts to explore the joint development of green hydrogen from Canadian renewables for export to Germany.
