66 Protech, a supplier of additive manufacturing systems in Nordic counties, attended the show to display some of the additive printers it can provide to parts manufacturers, UAV technicians and others. “When it comes to high-end printing, Stratasys’ FDM [fused depositing modelling] printers are very reliable and able to print some of the very best materials suited to aerospace applications,” Thomas Tønnesen at Protech Denmark said. Key examples of such materials are Nylon 12CF, which combines a Nylon with 35% carbon fibre content, enabling high strength-to-weight for UAV hull parts, and some Ultem systems, a high-temperature and chemicalresistant resin approved for use in commercial aeroplanes. “Additionally, the Stratasys SAF is a powder bed laser sintering printer, and that technology enables end-users to print in higher volumes, for instance in serial production situations. Although it prints smaller parts than the FDM technology, it does so at higher speeds,” Tønnesen added. ODU showcased its AMC-HD connector series. AMC-HD stands for ‘Advanced Military Connector, High Density’, which refers to the product family’s adherence to military standards, as well as combining power and data pins within the connector housing. “The AMC-HD hybrid connectors supply up to 10 A of current per power pin and 10.2 GB/s of data throughput per data pin – equivalent to HMDI 1.4, USB 3.2 and Ethernet 10 Gbit/s,” said Thomas Ullner at ODU Denmark. “The housings are dustproof and waterproof according to IP6K9K, and they’re made from lightweight materials including brass with Ruthenium plating. We do the surface treatments, CNC turning, stamping of contacts and plastic moulding in-house. That means we can make customised versions inhouse for customers who are seeking sufficient numbers.” The AMC-HD connectors feature 3 to 27 contacts when configured for breakaway locking. The connectors are also available with a screw-lock function. ODU offers three standard sizes of AMC-HD connectors, with diameters from 7 to 15 mm, and the expected lifespan of the connectors is a minimum of 5000 mating/unmating cycles. R2 Wireless exhibited an eponymously named, passive RF sensing platform for remotely detecting UAVs, GCSs and other wireless devices – such as mobile phones and tactical radios – that could potentially jeopardise uncrewed operations, critical infrastructure and sensitive sites. “It detects all incoming RF signals, classifies them, geolocates them with high precision and tracks them in real time using proprietary signal processing and edge AI algorithms,” Daniel Shizaf of R2 Wireless told us. “The platform detects any type of RF device, irrespective of communication protocol, frequency or modulation, encrypted or non-encrypted signals. The sensors we’ve demonstrated here in Odense can detect and find the location of wireless signals from 8 km away.” Each unit of the R2 Wireless detection solution consumes less than 10 W in normal operations, typically running on a small 12 V battery, and is IP67-rated for safe operations in outdoor environments and various weather conditions. Setting up the system takes around five minutes per unit and the system is ideal for remote sites, fully off grid, given that its battery enables it to work as an energyindependent unit.
