  Danish radars on French aircraft carrier

  Aarhus, March 25, 2020 - The French aircraft carrier Charles de Gaulle, which visits Danish waters this week, is equipped with two radar systems provided by Terma. The SCANTER 6000 radar systems are used for surveillance, search and navigation at sea - and in the air to guide helicopters on landing. In recent years, Terma has provided radar systems to a number of vessels in the French Navy through a collaboration with the French defense company Naval Group, which among others has built Charles de Gaulle. The French carrier has a fixed crew of about 2,000 men and weighs about 40,500 tonnes. It is accompanied by several escort ships and will be accompanied by the Danish frigate Niels Juel of the Iver Huitfeldt class during its visit. Through its long-standing partnership with the Danish Navy, Terma has provided radar systems, self-defense systems and command-control systems to all of the Navy's large naval vessels, including the three frigates, which also make use of the same radar type SCANTER 6000 as Charles de Gaulle. Terma's radar systems are used by many countries around the world on many different types of navy and coastguard vessels due to their ability to see small targets such as fast crafts and jet skis at long range and in all kinds of weather. Terma's radars are therefore also used for coastal and traffic surveillance e.g. at VTS Storebælt. About us The Denmark based high-tech Terma Group develops products and systems for defense and non-defense security applications; including command and control systems, radar systems, self-protection systems for aircraft, space technology, and aerostructures for the aircraft industry.

  These super-small drones no longer need a battery

  By: Kelsey D. Atherton To be a fly on the wall, an observer must be ubiquitous, unobtrusive and quiet. What if, instead, the observer was just a tiny fly-sized robot, independently powered, able to travel like its insect inspiration? That's one possibility from the long line of work on the RoboBee series of miniature flying machines, the latest of which recently flew independently under its own photovoltaic power. RoboBee is a long-running project of the Harvard Microrobotics Lab and the Wyss Institute for Biologically Inspired Engineering. The end goal is ultimately controlled swarms of insect-sized flying machines, with visions of these swarms performing everything from plant pollination to surveillance. These are ambitious aims, and all have been hindered to this point by a fundamental constraint on the form: the robots are too small to carry batteries. Much of the flight design uses a tethered power supply, allowing the designers to craft Piezoelectric motors that expand and contract as electrical current passes through the muscle-like membranes. This created wings that could flap and propel the robot upward, but it wasn't until recently that the robot could do it on its own power supply. RoboBees are smaller than any drone currently employed by the U.S. military, minute enough to make the palm-sized Black Hornet feel gargantuan. Without a sensor payload, it'd be a novelty, but the military has already invested in cheap, expendable sensor-carrying drone gliders for tasks such as meteorological data collection. Should this power supply enable RoboBees to support a meaningful sensor package, they could be used in a similar fashion, scattered as sensors that can flap their way into a new position. Holding six solar power cells on a stick, and with a second set of wings, the vehicle successfully flew under its own power, even if only for the briefest of moments. The researchers' documentation of their project was published in scientific journal Nature June 26, appearing under the title “Untethered flight of an insect-sized flapping-wing microscale aerial vehicle.” The whole RoboBee weights 259 milligrams, or less than a paperclip, and under special lights was able to generate enough lift to support an additional payload of 70 mg, which could be used for lightweight sensors, control electronics, or larger power supply in the future. Fitting sensors to a craft the small is likely a challenge, but also essential for the promise of the device. There is also the small matter that, even using photovoltaic cells, the robot needs an alien sun to fly. “The Robobee X-Wing needs the power of about three Earth suns to fly, making outdoor flight out of reach for now,” stated the summary from Harvard's School of Engineering and Applied Sciences. “Instead, the researchers simulate that level of sunlight in the lab with halogen lights.” Should the sensors exist, and the device become capable of outdoor flight, microrobotics could become a ubiquitous part of modern life, performing functions alongside insects and relaying sensor information back as an unseen intelligence platform. https://www.c4isrnet.com/unmanned/robotics/2019/07/08/these-super-small-drones-no-longer-need-a-battery/

  Air Force defers NGAD decision to Trump administration

  The Air Force will keep maturing the technology for a potential sixth-generation NGAD fighter, but will let the Trump administration decide how to proceed.
