Universidad de Alcalá-OTRI posted this:Portable device to measure the displacement maps on surfaces in the three spatial directionsA Spanish research group from the Department of Signal Theory and Communications of the University of Alcalá along with a Spanish research group from the Department of Mechanical and Mining Engineering of the University of Jaén has developed a portable optoelectronic device to measure the displacement of each surface element in an object when is subjected to deformation. In particular, the device allows obtaining maps of long range displacement (greater than mm) in dynamic regime (in real time). Thus this system is very useful in the experimental study of the materials’ mechanical properties, especially if they suffer large deformations at high speed. It is a computationally simpler alternative and more inexpensive than the digital mapping technique for 3D images which is currently the only one allowing such measures. The group seeks licensing agreements, collaborative and commercial agreements with technical assistance.

Furthermore, the sintered ceramic substrate guarantees superior adhesion and resistance to fracture under high mechanical loads. The fabricated temperature sensitive diamond surface comprises well adhered ohmic contacts deposited on the backside of the dielectric ceramic substrate. This configuration prevents interaction between the temperature sensitive surface and the surrounding environment which is essential for biochemical devices applications. Furthermore, the planar geometry of the disclosed thermistor maximizes the contact region between the temperature sensitive surface and any solid flat surface on which it is placed. In this way, improved response times are obtained comparing to traditional round shaped thermistors.

Universitat de València posted this:Method for producing nanocorundumResearchers from Geology Department of University of Valencia have developed a novel method for producing corundum of low crystallinity (nanocorundum) using natural or synthetic commodities in solid state, without pre-treatment. The process of the invention makes it possible to obtain a product with a nanocrystalline nature, composed of tabular- or plate-shaped primary nanoparticles in porous microcrystalline aggregates, which facilitates the subsequent disaggregation process thereof into powders that have an immediate application as ultra-fine abrasives and as loads (or fillers) in plastics or other types of materials. This characteristic represents a significant advantage of the product of the invention, since compact corundum is a hard, difficult-to-grind material.

Universidad de Alcalá-OTRI posted this:New technology for applying attitude optimal control to aircrafts and satellitesThe developed technology for being applied to aircrafts and satellites in order to perform attitude optimal control is cost-effective and robust against changes in the environment or in physic structure of the platform. One of the pillars of the new technology is the lack of mathematical models for the performance of control and, instead, it uses the experience gained through interaction with the environment and the platform. As a consequence of the internal behaviour of the technology, the new system is not sensitive to sampling period used.

They can be attached to existing blades so are particularly suitable for retrofitting to larger blades, such as wind turbines. They are however applicable to a wide range of blades moving in air and water, for example turbines, fans, rotary wings and fixed wings. The scale of application ranges from small drones (small blades operating at high speeds) to large wind turbines (large blades operating at slower speeds).
Brunel University London posted this:Magnesium Alloys with Improved CastabilityMagnesium alloys are lightweight and so provide the best solution for reducing weight in the transport sector. However increasing the use of these alloys to replace steel has been hampered by their lack of ductility and low yield strength. This is due to the large grain structure, defects and inter‑metallic particles formed during casting. New magnesium alloys produced using a novel Magnesium Boride grain refiner have a much finer structure with fewer defects, resulting in improved ductility and strength in addition to reduced defects during casting and ease of casting complex shapes.
Brunel University London posted this:Actively-Controlled Morphing Wing Adaptive Skin for Enhanced Aircraft Control and PerformanceTo meet the ever increasing demand for more efficient, robust, and cost effective aircraft wing designs, conventional control surface methodologies need to be replaced by “morphing” technologies. Brunel University has developed a viable and realistic active wing/blade twist technology with an adaptive skin for seamless and adjustable changes in wing/blade twist angle. The technology is the ability to maintain a rigid skin with a low drag (smooth surface finish) despite high twist deformation during operation. Moreover, the structure is lightweight, and strong enough to carry aerodynamic loads.

Brunel University London posted this:Zagblade: Reduction of aero acoustic pollution by introducing novel serrated trailing edgesAn aerofoil blade design that reduces trailing edge noise by means of a saw-tooth serration filled with a porous material. The serration and porous material work constructively with each other to significantly improve the aero-acoustic performance. An optimal choice of the porous materials has been identified, where it can achieve broadband noise reduction whilst completely suppressing the vortex shedding tone. This new device is more industrially-ready than the conventional “add-on” type serration due to its superior structural integrity. In addition it produces an aerodynamic performance similar to that of the baseline aerofoil. Applicable to a wide range from applications from drones, UAVs, aircraft engines, wind turbines and fan blades.
