Turkey banks on military drones to extend power, regional clout

The “dronization” of Turkey’s power projection abroad continues with a new unmanned aerial vehicle that Ankara plans to use against PKK militants in Iraq and Syria as well as in brewing regional conflicts.

"Turkey is gearing up to start production of a new high-altitude, long-endurance drone, hoping to extend its military reach in the region..."
"Ankara plans to have six Akincis operational by early 2021, with Azerbaijan, Malaysia, Qatar and Ukraine said to be interested in purchasing the drone."

After meeting several primary objectives during risk reduction flights at the U.S. Army's Dugway Proving Ground in Utah in late July, DARPA's Gremlins program now is targeting additional tests of its X-61A vehicle later this year. The program seeks to develop and demonstrate air launch and air recovery of up to four unmanned aerial systems (UASs), known as Gremlins Air Vehicles (or just Gremlins), within 30 minutes.

Over several days in July, the technology development team completed multiple flight tests of the Gremlins air-vehicle ground and recovery systems, including demonstration of a recovery system safely retrieving and stowing the air vehicles.

The team also conducted a controlled launch of a Gremlin flying for more than two hours and performed rendezvous and autonomous formation station-keeping between the air vehicle and a C-130 at a separation of 125 feet.

The July flights follow the program's first flight test in November 2019, during which the program completed one captive-carry mission, and an airborne launch and free flight lasting more than 90 minutes.

"The air vehicle performed beautifully from launch through mission modes, and the consistency between the flight tests in November and July increases confidence in the X-61A," said Scott Wierzbanowski, the Gremlins program manager in DARPA's Tactical Technology Office.

"However, we made a decision to delay the first air recovery attempt and instead focus on key risk reduction activities to better ensure a smooth air recovery test later this year."

The program now calls for flight tests to resume in October with the key objective to recover first one, and then two, air vehicles in the same flight. By the end of the year, the program aims to complete the test series, culminating with airborne recovery of four Gremlins within 30 minutes.

This final demonstration will showcase the capability of safe, effective, and efficient air recoveries, opening the way to dramatically expand the application and utility of attritable UASs.

Mission flexibility and affordability are the key attributes of the Gremlins system, which would launch groups of UASs from multiple types of military aircraft while the latter remain beyond the range of adversary defenses.

The Gremlins program is using a C-130 as the demonstration platform, but the recovery system is designed to be easily modified and compatible with a wide array of transport aircraft and weapons systems. Once Gremlins complete their missions, the transport aircraft would retrieve them in the air and carry them home, where ground crews could prepare them for their next use within 24 hours.

Gremlins can incorporate several types of sensors weighing up to 150 pounds, and integrate technologies to accommodate different stakeholders and missions.

DARPA's Gremlins Program completes second flight test in demonstration series

At IROS last year, Caltech and JPL presented a prototype for a ballistically launched quadrotor—once folded up into a sort of football shape with fins, the drone is stuffed into a tube and then fired straight up with a blast of compressed CO2, at which point it unfolds itself, stabilizes, and then flies off. It’s been about half a year, and the prototype has been scaled up in both size and capability, now with a half-dozen rotors and full onboard autonomy that can (barely) squeeze into a 6-inch tube.

Just tämän tyyppisestä dronesta olen unelmoinut kauan aikaa. Tankkiin tämä menisi hieman modaamalla, mutta uskon että on useita kulkuneuvoja mihin tämä myös kävisi.
 

Last year, Spectrum reported on Japan’s public-private initiative to create a new industry around electric vertical takeoff and landing vehicles (eVTOLs) and flying cars. Last Friday, start-up company SkyDrive Inc. demonstrated the progress made since then when it held a press conference to spotlight its prototype vehicle and show reporters a video taken three days earlier of the craft undergoing a piloted test flight in front of staff and investors.

The sleek, single-seat eVTOL, dubbed SD-03 (SkyDrive third generation), resembles a hydroplane on skis and weighs in at 400 kilograms. The body is made of carbon fiber, aluminum, and other materials that have been chosen for their weight, balance, and durability. The craft measures 4 meters in length and width, and is about 2 meters tall. During operation, the nose of the craft is lit with white LED lights; red lights run around the bottom to enable the vehicle to be seen in the sky and to distinguish the direction the craft is flying.

The SD-03 uses four pairs of electrically driven coaxial rotors, with one pair mounted at each quadrant. These enable a flight time of 5 to 10 minutes at speeds up to 50 kilometers per hour. “The propellers on each pair counter-rotate,” explains Nobuo Kishi, Sky Drive’s chief technology officer. “This cancels out propeller torque.” It also makes for a compact design, “so all the craft needs to land is the space of two parked cars,” he adds.

But when it came to providing more details of the drive system, Kishi declined, saying it’s a trade secret that’s a source of competitive advantage. The same goes for the craft’s energy storage system: Other than disclosing the fact that the flying taxi currently uses a lithium polymer battery, he’s also keeping details about the powertrain confidential.

Underlying this need for secrecy is the technology’s restricted capabilities. “Total energy that can be stored in a battery is a major limiting factor here,” says Steve Wright, Senior Research Fellow in Avionics and Aircraft Systems at the University of West England. “Which is why virtually every one of these projects is aiming at the air-taxi market within megacities.”

31. Insurgent Airforce: Weaponising Commercial Drones

Eli 100-200$ dronen kyytiin jokin räjähde, se lennätetään yöllä suurinpiirein USA:n tukikohdan päälle ja sammutetaan ilmassa moottori.

Osumatarkkuus tietenkin mitä sattuu, kelpaa tuollaisenaan lähinnä häiriköintiin. Mutta yksittäistä pientä dronea on yllättävän vaikea torjua.
