UAVs con electrónica embebida

¿Es posible fabricar un UAV mediante Impresión 3D... y que lleve embebida la electrónica? La respuesta es SÍ, SIN DUDA.

El reto lo ha protagonizado Phillip Keane, estudiante de la Universidad Tecnológica de Nanyang (Singapur), quien ha diseñado y fabricado un UAV con material Ultem 9085, utilizando para ello un sistema de producción 3D Fortus 450mcAunque se trataba sólo de un prototipo, el reto demostró la posibilidad de llevar a cabo una fabricación automatizada de UAVs complejos y funcionales mediante impresión 3D.

US Air Force to Phase Out MQ-1 Predator

The US Air Force said that it is retiring the 21-year-old MQ-1 Predator UAV and is transitioning to the MQ-9 Reaper: "We are going to stop flying the MQ-1 completely by July 1, 2017," 20th Attack Squadron commander Lt. Col. James said in the release. "We're converting an MQ-1 squadron… to an MQ-9 squadron in combat operations without taking a single day out of combat."

The Air Force explained the MQ-9 Reaper will be used for close air support for US troops along human piloted aircraft, and also for intelligence gathering and real-time reconnaissance: "The MQ-9 is better equipped than the MQ-1 due to its high definition sensors and increased speed," the release stated. "The fresh MQ-9 design picked up where the MQ-1 left off, boasting a nearly 4,000-pound payload and the ability to carry missiles and bombs."

Russian military will receive Svarog's VR helmet to control UAVs

Despite its cumbersome appearance, the device weighs 400 g, which is a standard weight of the current VR helmets.

"Now the Svarog is under trial and will be delivered to the Ministry of Defense as soon as possible during this year," Alexei Pechkin, a researcher at Mari State University, told the Izvestia newspaper. "We continue to improve the helmet and experiment with the characteristics of its lenses, but even now the resolution of the screen is twice that of its foreign rivals, while the angle of vision of Svarog is limited by the user's natural field of vision ".

The device has a set of sensors to measure the position of the eyes and the inclination of the head: The operator can vary the altitude of the UAV by raising or lowering his head as well as change the direction of the flight by moving only his eyes to a point of interest.

"Using a VR device to control an unmanned reconnaissance aircraft has many advantages over the traditional display and the joystick," says Maxim Chizhov, a VR expert. "An updated VR helmet gives the UAV operator a more realistic picture of the battlefield, allowing for faster decision making and more effective drone control at high speed."

IDF intercepts Hamas UAV

An Israel Air Force F-16 downed an unmanned aerial vehicle belonging to Hamas on Thursday 23th afternoon, intercepting it after it left the Gaza Strip and bringing it down into the sea before it managed to enter Israeli airspace.

Weaponized drones is something “that Israel must prepare for,” Yoram Schweitzer, senior research fellow and head of the Program on Terrorism and Low Intensity Conflict at the Institute for National Security Studies in Tel Aviv, told in a recent interview.

Hamas and Islamic State have used weaponized drones to carry out attacks: Regarding Hamas, during Operation Pillar of Defense in 2012, the IDF struck facilities that were being used to develop drones capable of carrying explosives, with the OC Southern Command at the time, Maj.-Gen. Tal Russo, saying that the military destroyed “advanced weaponry like the development of a UAV that isn’t used for photography but for attacks deep inside Israel.”

And regarding Islamic State, recently posted several photos online with instructions on how to weaponize a small quadcopter with an RKG-3 anti-tank stick grenade, RPG-22 one-shot disposable anti-tank rocket launcher, and RPO anti-tank rocket. It has also made dozens of claims of having used drones to drop explosive devices onto Iraqi troops in the ongoing battle for Mosul.

UAV Swarms

The military thinks differently about UAVs, but they still want to make the most of their capabilities.

However, since not many armed forces can afford to buy a large UAV that can carry payloads of multiple sensors to simultaneously meet the needs of different ground and air forces, the armed forces are beginning to demand UAVs capable of operating in groups or rather in swarms.

The UAV industry has seen a gold reef in that demand, and wants to make the most of it. ¿What will the future be? ¿Who knows? But as UAV swarms are here, I think the future is there: Two eyes can see more than just one, and four bombers can reach more targets than just two.

Indonesia receives Skeldar V-200

Indonesia has become the first customer of UMS Skeldar to receive and complete acceptance tests of the company's Skeldar V-200 rotary-wing Unmanned Aerial Vehicle (UAV), the Switzerland-based developer of unmanned aircraft systems said in a 16 February press release.

The Ministry of Defence (MoD) in Indonesia deployed the Skeldar V-200 as part of performance and acceptance tests during the fourth quarter of 2016, paving the way for the procurement and pilot training in the country, the company stated. The move, which was the first delivery of the only heavy fuel UAV platform in its class, also marked the beginning of a training programme contract with the Indonesian MoD.

It is unclear, however, how many of the rotary-wing UAVs have been delivered to Indonesia as part of the deal. "With the world's second-longest coastlines, the tests and patrol evaluations [in Indonesia] confirmed the multi-payload and low footprint of the Skeldar V-200 across land and navy applications," said UMS Skeldar, which is a joint venture between UMS AERO Group and SaabThe contract in Indonesia confirms not only the importance of Intelligence, Surveillance, and Reconnaissance (ISR) and Search And Rescue (SAR) strategies within complex territories, but also "how UAVs can be used as a stand-alone or integrated platform deployed from land bases or seaborne", said UMS Skeldar training director Ewen Stockbridge-Sime.

According to the company, the V-200 is a multirole helicopter UAV suited for a wide range of applications, such as reconnaissance, identification, target acquisition, and electronic warfare. UMS Skeldar says on its website that the 1.3 m-high Skeldar V-200 has a maximum airspeed of 140 km/h (75 kt), a service ceiling of 3,000 m (9,842 ft), a maximum take-off weight of 235 kg (518 lb), and an endurance of more than five hours depending on the size of the fuel tank module and the payload configuration.
