When the air display starts each afternoon at the Farnborough International Air Show, business transactions pause and eyes roll heavenward, surrendering to the raucous power play. A major part of the attraction is the evident – if calculated – risk the aviators take.  The organisers of this sky-borne shop window for aviation hardware may appear to have little more to do than arrange the order in which the players make their entrances and their exits. That was indeed true a long time ago. Now, however, both the air display and static park at the show are painstakingly choreographed. The aviators are definitely not given carte blanche. There is plenty of activity in prospect. The star debutante this year will be a Lockheed Martin F-35B Lightning II, the first jet with vertical landing capability since the British Aerospace Harrier started wowing the crowds in the mid-1960s, flown by the UK Royal Air Force’s Sqn Ldr Hugh Nichols. On the civil side, Airbus’s still-under-test A350 will take its first Farnborough bow. And the organisers have to be prepared for a full aerobatic display team because the Royal Air Force’s Red Arrows will perform on the last three days. When the Farnborough air show began back in 1948, accidents at air shows, often fatal to pilots and sometimes to onlookers, were not rare. Some of the crashes were the result of test pilots pushing their luck with experimental aircraft in an era of less sophisticated engineering; others were victims of the risk-taking culture left over from the Second World War. Aviators were expected to be dare-devils, and some of them embraced that image with enthusiasm. Picture: Pilots putting types like the Saab Gripen through their paces must adhere to strict guidelines.     Aviation professionalism has evolved as the laws defining corporate responsibility […]

When it comes to 3D scanning, more and more solutions are becoming available as the months go by. 3D scanning is allowing us to take photographs of people and things, in ways that we could never imagine before.  Instead of only being able to look at a flat, 2-dimensional photo, we can now interact with 3D photographs via our computers, and create 3D replicas with the use of 3D printers.  A company called itSeez3D has come up with a new iOS application, that when paired with the Structure Sensor allows people to take full 3-dimensional photographs of people and objects. It has an incredible ability to capture color and structural information of a subject, and then process it into a realistic looking 3D model. The app has the capability of capturing high resolution data, and features a unique augmented reality feedback system which enhances the scanning process (see video below). Once a scan has been captured, users have the ability to email the 3D representation to their friends, in .ply or .obj file formats, or simply upload it to sketchfab.com. Users can also 3D print it at home on their own 3D printers. If it is printed on an at-home FDM or SLA 3D printer, however, the colors will not print because of the current technology available. On the other hand, if a high quality 3D printer is used, the colors will be able to be preserved. For example, users could send their 3D scan to Shapeways or another service, to have it printed in full-color sandstone. itSeez3D has already uploaded 18 different models that they have created using the app, to their sketchfab profile, and I must admit, the quality appears to be excellent. Uploaded models include several people as well as a stuffed animal, a sneaker, a mug, […]

Aluminium foam is used for applications that requires high level of energy and sound absorption characteristics. Researchers have developed an innovative process to make high strength cellular aluminium foam with help from some salt. Aluminium foam exhibits unique properties when compared to its dense form, particularly its lightweight characteristics. Generally, the foam can be divided into two categories; closed cell and open cell, both have different characteristics and applications. The features of the closed cell are, the pores structure is isolated and they are not connected to each other. This type of aluminium foam is suitable for application that requires high level of energy and sound absorption characteristics. It has been used widely in many structural parts, particularly in areas exposed to high damping capacity, for example in the automotive front bumper component. Meanwhile, the open cell, owing to greater level of connectivity of the pores, the structure has been accepted and used in thermal management applications. One such promising application is as a heat exchanger, particularly as a cooling medium to transfer heat, due to the development of its porous structure, which provides greater surface area, thus, enabling improved heat transfer efficiency. Producing a combined structure of open and closed cell in one volume component appears to be a difficult process due to the different processing techniques involved and their individual limitations. Therefore, in this study, an innovative processing route for high strength cellular aluminium foam (CAF) by integrating porous and dense structures is presented. The CAF is well known as a light-weight product exhibiting high level of inter-connected porosity which is very useful as a thermal management application, particularly as a heat transfer or cooling medium. However, the level of strength for the CAF is not really promising when it is subjected to high impact; thus, limit its […]

The Network Time Machine LTE/VoLTE, is a portable LTE troubleshooting appliance that helps wireless carriers resolve network performance issues quickly and cost effectively. This ability is crucial to reducing customer churn, as subscribers who switch wireless carriers increasingly point to poor customer care and inadequate network performance as their reason for leaving. The Network Time Machine provides extensive network and application visibility, as well as the forensic details necessary to solve signalling or data performance problems in 20 Gbps carrier environments. Using Network Time Machine, carriers can measure and prove network performance, resolve subscriber issues and deliver the best possible consumer experience to meet growing voice, video, and data demands. “The proliferation of affordable smartphones, tablets, and other devices has sparked an ever-increasing popularity of mobile videos, games, and data applications,” said Amit Rao, general manager of the Carrier Wireless Core product line. “While networks have evolved from 3G to 4G/LTE to meet performance demands, network monitoring technologies have not kept pace. Network Time Machine LTE/VoLTE is the first troubleshooting appliance that can deliver the 20Gbps performance required for high-performance wireless networks and—even more important—for creating loyalty among today’s fickle wireless subscribers.” According to a recent Ovum survey*, 27 per cent of wireless subscribers who had changed carriers in the previous month cited “low network quality/speed of the services” as their reason for switching. More than 30 per cent said poor customer care was a key reason. While today’s wireless carriers need better and faster ways to resolve the network issues that drive customer complaints, most of their network engineers rely on solutions that lack capture performance or fragile appliances that must be shipped to unmonitored high-traffic LTE port locations. These tools often break and require complex configurations to make them operational. Network Time Machine is a rugged appliance that […]
