68 Report | AUSVI Xponential 2022 “The focus of the update is the surveying package,” said Laurent Zimmerli. “We extended the software platform, so that platforms like the Astro – the multi-rotor from Freefly, who we’ve partnered with for a long time – can engage in high-precision surveying. “We’d already integrated the Sony Alpha 7R IV camera for high-resolution pictures, but we’re also starting to integrate a Phase One camera, and we can now do onboard geo-tagging through our Skynode, as well as PPK processing to increase the precision of the geo-tags to that of professional-grade survey results.” The updates will also include integrations of compatible parachute systems, with the company’s stand featuring a Watts Innovation Prism Sky integrating a parachute pod. Volz Servos was on hand to discuss its DA 30 HT MCCS actuator, which has recently been updated with the company’s unique magnetic coaxial clutch sensor technology. “This electromagnetic clutch was developed for optionally piloted vehicles so that the pilot can decouple the output shaft from the servo to take direct control,” explained Phillipp Volz. “The coaxial shaft features an internal shaft with the position sensor that runs through the output shaft into the servo, so that whether the clutch is powered or not, the servo always knows the position of the output shaft. “That helps a lot in making the servo more compact, and we’ve also been able to seal it to IP 67 standards. And with customers installing capstans into aircraft, they can integrate this servo without needing to worry about where to mount the external position sensor, or about spending long, painstaking hours to replace it if needed. “If the clutch is powered, it electromagnetically closes, and it’s spring-loaded so if it’s unpowered, it just opens back up,” Volz added. “And since it’s a toothless clutch, it can’t have a hard failure. “Also, owing to the way we perform position sensing of the output shaft there’s no position error when connecting. The servo always knows the position of the external output shaft, regardless of whether the clutch is engaged or disengaged.” This latter innovation also enables the flight control computer to digitally track the position of the servo’s output. The new design eliminates the need for additional external cabling, and reduces the amount of electronics, decreasing the overall MTBF. The magnetic coaxial clutch system is now available on Volz’s complete range of actuators. We also caught up with Physical- Logic to learn about some of its latest r&d and hence its plans for its next generations of MEMS accelerometers. Aviram Feingold told us, “At the moment, many functions of our closed- loop accelerometer products are still embedded on the PCB, and we work with our customers to design the PCB for their systems’ interfaces. But we are developing a new range of products in which effectively all the electronics are imported from the PCB into the accelerometers’ ceramic chip packages. “Some functions will be defined in the ASIC itself, with some on the surface mount devices that we’re moving inside the chip form factor.” The new products include the MAXL- CL-3030, which has a ±30 g sensing range, and the MAXL-CL-3015 with a ±15 g range. Both accelerometers provide a year of bias repeatability performance within 250 µ g , and a year of scale factor repeatability within 250 ppm. The series will also include the MAXL- CL-3050 with a ±50 g sensing range and the MAXL-CL-3070 with a ±70 g range. Their one-year bias repeatabilities will be accurate to 500 µ g , while their one- June/July 2022 | Uncrewed Systems Technology Volz’s DA 30 HT MCCS actuator Physical-Logic’s new accelerometer
