Xponential 2024 | Show report Also its A Series of motors which are optimised for fixed wing UAVs, and its HK5 motors which are for helicopter or high speed UAVs, and have recently been optimised with a new internal structure for improved cooling. “As well as having all these systems ranging from 500 W to 10,000 W, COTS and in-stock, we can customise for different performance requirements, Kv ratings, connectors, engravings, and more,” Dahl added. Hitec has customised some new servos with improved, applicationspecific functions, based on actuator designs from its MDB961 series. “Like the 961 servos, these are engineered with high torque, waterproof and hardened cases, and hardened steel gears, but one of the new units has a robotic servo-type bracket - an axial bracket, for applications where the servo needs to take higher axial loads,” said Shawn Spiker. “A lot of requests for that come from tiltrotor engineers, who are mounting the motor-propeller drive straight onto the servo. The axial bracket supports the servo arm on both sides, takes a lot of pressure off of it, and handles gyroscopic forces well. It’s also in-demand from animatronics engineers for use in arms, knees and other robotic limb joints that need to handle higher loads.” Another of the new servos comes with a US-made circular MA connector, per request from several US-based companies eyeing Blue- and Green-UAS ratings. Such servos are designed with 32 V architectures to enable handling of the bigger, shielded cabling of such connectors. Gladiator Technologies was walking the aisles to discuss its GA50, a new chip-based accelerometer introduced in early 2024. “It’s an open-loop accelerometer, and comes in multiple g-range variants, from 5 g all the way up to 70 g,” said Eric Yates. “We’re looking for opportunities to integrate it with other inertial products, particularly groups looking to build new tactical systems.” At 70 g, the GA50 has a bandwidth of 300 Hz, a one year bias repeatability of 7 mg, and a bias stability of 180 µg. At 5 g, its bandwidth is 250 Hz, its bias repeatability is 0.8 mg, and its bias stability is 60 µg. Across all g-ranges, it weighs just under 0.7 g, measures 8.9 X 8.9 x 3.2 mm, consumes just under 13 mA (on a 3.3 V DC power supply) and can function in temperatures from -50˚C to +85˚C. Aircraft Electronic Engineering GmbH (AEE – a subsidiary of Volz Servos) presented its Next-generation Flight Control Computer (NFCC), which it has co-developed with the Technical University of Munich. “AEE is an EASAcertified production, maintenance, and alternative design organisation, focused especially on commercial avionics,” Nils Schlautmann told us. “To that end we’ve created the NFCC using similar approaches and technologies to some of our other products, which have been flown on vehicles of 700 kg+ MTOW already,” “We’ve designed it to be extremely flexible in terms of interfaces – both the types and total number available – for customers that want to get started using it, but maybe don’t yet know 100% what kinds of protocols or channels they want.” The NFCC hence can come with either two D38999 or EN4165 connectors, providing up to eight CAN interfaces, up to 16 ARINC 429 Rx ports, up to 8 ARINC 429 Tx ports, 8 serial ports (including RS-232, -422 and -485), and up to 32 discrete inputs as well as 16 discrete outputs – per lane, depending on the chosen configuration. “It’s available with COM-MON [Command and Monitor] or Dual Lane architectures; though you can also configure it to only monitor,” Schlautmann added. “It has twin T1024 or optionally T1042 CPU modules , with direct Ethernet for connecting with them.” UXV Technologies has developed a soldier-borne compute module (SBCM) designed for both dismounted soldier applications and vehicle mounting. “The SBCM is built around an Nvidia Jetson Xavier NX computer to process raw data being downlinked, such as data from a gimbal or other mission payload. This allows soldiers to utilize the information as quickly as possible mid-mission,” explained Frederik Bergenfelt Friis of UXV Technologies. “Combined with the Soldier Robotics Controller [SRoC], the SBCM can connect multiple radios to control several vehicles simultaneously. It can also switch between different sensors to process and display intelligence data from various locations as needed.” He added that the module is also a Nett Warrior hub compatible system thanks to UXV Technologies’ Swappable Radio 107 Uncrewed Systems Technology | June/July 2024 Hitec’s custom servos feature improved, application-specific functions, and are based on actuator designs from its MDB961 series
