Raytheon Intelligence & Space and Kord team-up to defeat multiple mortars and large drones with Stryker-mounted high-energy laser

Posted by in categories: business, drones, energy, military, space

LAS CRUCES, N.M., May 16, 2022 /PRNewswire/ — In four weeks of continuous live-fire exercises, an industry team led by Raytheon Intelligence & Space, a Raytheon Technologies (NYSE: RTX) business, and Kord, a wholly owned subsidiary of KBR, defeated multiple 60mm mortar rounds with a 50kW-class high energy laser integrated on a Stryker combat vehicle.

The directed energy weapon system — part of the U.S. Army’s Directed Energy Maneuver-Short Range Air Defense, or DE M-SHORAD — acquired, tracked, targeted and defeated multiple mortars and successfully accomplished multiple tests simulating real-world scenarios.

Continuing to put the DE M-SHORAD system to the test, the recent operational assessment at White Sands Missile Range also included defeating several small, medium and large drones.

Blainjett’s hemi-rotor concept promises faster, more efficient VTOL performance

Posted by in categories: drones, military, robotics/AI

Blainjett Aviation announced that initial testing of its hemi-rotor aerodynamic concept has confirmed its potential to deliver faster, more efficient performance in VTOL aircraft. Subscale tests demonstrated the novel configuration’s net positive lift and low drag through the ascent/hover, cruise, and descent/hover phases of flight.

The startup is applying the hemi-rotor concept to a subscale drone as part of a path to demonstrating that the configuration can scale to larger unmanned or manned aircraft in eVTOL applications from package delivery and cargo to transport and tactical military roles. Blainjett’s hemi-rotor design situates familiar vertical lift rotors partially inside opposite sides of an enclosed fuselage. The airfoil-shaped fuselage also houses a pair of electric motors to drive the lift-rotors. Situated in the empennage above an inverted V-tail, the third motor powers a pusher prop.

Scientists send robot into furious hurricane and capture wild footage

Posted by in categories: climatology, drones, robotics/AI

Hurricane researchers sent a marine drone into Hurricane Fiona, where it captured intense footage of the tropical storm. The research drone will help scientists better understand how tropical storms rapidly intensify.

Recently, the collaboration between the U.S. National Oceanic and Atmospheric Administration (NOAA) and Saildrone, a company that develops sailing drones, did exactly that. They sent a robot into Hurricane Fiona, the tropical storm that has deluged Puerto Rico and is now headed towards Canada’s east coast, Mashable reported.

How drones, crypto, and satellites are changing the face of war / Thomas Frey & Trent Fowler

Posted by in categories: cryptocurrencies, drones, satellites

Russia’s war on Ukraine has turned a lot of assumptions about the fundamental nature and trajectory of how wars are fought, on its head.

For one thing, Ukraine’s strong defense has upended conventional wisdom about big powers being able to violate at will the sovereignty of little powers.

3D-printed drones work like bees to build and repair structures while flying

Posted by in categories: 3D printing, drones, robotics/AI

The technology, which has been tested in the lab, could ultimately be used for manufacturing and building in difficult-to-access or dangerous locations such as tall buildings or help with post-disaster relief construction, say the researchers.

3D printing is gaining momentum in the . Both on-site and in the factory, static and print materials for use in , such as steel and .

Undefined claims 4.5-min flight for its “silent” ion-propulsion drone

Posted by in categories: drones, space travel

Florida’s “silent” flying dish-rack, powered by ionic propulsion, is on track for commercial rollout in 2024, according to Undefined Technologies, which has released new outdoor flight test video. We remain curious, but unconvinced it’ll be viable.

The “Silent Ventus” drone doesn’t use propellers to fly. Instead, its entire broad structure creates two stacked grids of electrodes, designed to create high-voltage electric fields that can ionize the oxygen and nitrogen molecules in the air, freeing electrons to give them a positive charge, and then propelling these downward to create an “ionic wind” that can produce thrust.

Animal-inspired flying robots are going to 3D build mid-flight

Posted by in categories: 3D printing, drones, robotics/AI

The drones will help the construction industry in hard-to-reach and dangerous places.

Consider the drone bees. These bees, which probably gave their name to today’s drones, are also may have inspired by their physical features. Let’s learn how.

Matternet’s delivery drone design has been approved by the FAA

Posted by in categories: biotech/medical, drones, robotics/AI

The California-based Matternet has been testing its Model M2 drone over the past four years in the US as part of the FAA’s Unmanned Aircraft System (UAS) program. Matternet says getting the green light from the FAA could help streamline the process of “implementing new networks and getting approvals.”

Matternet partnered with UPS in 2019 to deliver medical supplies in North Carolina, and later started delivering prescriptions in Florida. Matternet also expanded its footprint to Switzerland, where it teamed up with the Swiss Post to deliver lab samples and blood tests. The program was briefly suspended in 2019 after its drones suffered two crashes in the country, but Matternet has since announced that it’s taking over the Swiss Post’s drone delivery program starting in 2023.

In a statement, the FAA says Matternet’s Model M2 drone “meets all federal regulations for safe, reliable and controllable operations and provides a level of safety equivalent to existing airworthiness standards applicable to other categories of aircraft.” The four-rotor drone’s been approved to carry four-pound payloads and fly at an altitude of 400 feet or lower with a maximum speed of 45mph.
