China's new drone company is building a UAV with a 20-ton payload

The TB-001 Scorpion, Tengoen's flagship vehicle, is a twin-engine, double-tail drone. It has a maximum takeoff weight of 2.8 tons, a range of more than 3,700 miles, and provisions to carry two 220-pound bombs or missiles. Tengoen has also partnered with Chinese delivery company SF Express to build a souped-up TB-001 for cargo delivery, increasing the drone's size to 3.3 tons, with a 1.2-ton payload. In December 2017, the modified TB-011 showed off its capability by para-dropping supplies to a Huawei repair crew fixing a cell tower in the mountainous Yunnan Province.

DARPA has successfully completed its Anti-Submarine Warfare (ASW) Continuous Trail Unmanned Vessel (ACTUV) program and has officially transferred the technology demonstration vessel, christened Sea Hunter, to the Office of Naval Research (ONR).

ONR will continue developing the revolutionary prototype vehicle—the first of what could ultimately become an entirely new class of ocean-going vessel able to traverse thousands of kilometers over the open seas for month at a time, without a single crew member aboard—as the Medium Displacement Unmanned Surface Vehicle (MDUSV).

In an effort to make robotics a reality inside its combat formations, the U.S. Army is planning on testing the first prototypes of the Robotic Combat Vehicle by 2021.

"The Army has realized that robotics is going to be critical for our success in the future," Col. William T. Nuckols, director of the newly formed Training and Doctrine Command Project Office for Maneuver Robotics and Autonomous Systems, told Military.com recently.

"We are going to build some tech demonstrators of the Robotic Combat Vehicle and actually get it into the hands of soldiers, ideally between 2020 and 2021," Nuckols said.

These early prototypes will be built from the Army's legacy vehicle platforms, but they "will likely not look like the legacy vehicle," he said.

The new robotic prototypes will have all the equipment necessary to make them semi-autonomous, so they can maneuver for short distances and engage targets, Nuckols said.

The effort will be no doubt be challenging, he said, pointing to the recent advances in self-driving cars.

"That is not easy, and that is in a fairly pristine environment with well-defined roads," Nuckols said. "When you take it to that step of combat, which is probably that most chaotic thing that mankind does, that is a whole new ballgame ... especially when you are talking about blowing things up and killing people. You have to be very careful."

The tech demonstrators of the first Robotic Combat Vehicles will be the first step in a long learning process, he said.

"It will be a chance to both test our ability to build a Robotic Combat Vehicle in terms of technology, and it's also going to be an opportunity to assess how the soldiers would use that capability," Nuckols said. "So it will be an operational test as well as a technical test."

If all goes well, "we are looking at potentially building a number of purpose-built Robotic Combat Vehicles sometime immediately following that 2021 experiment," he said.

Tämä tulee olemaan mielenkiintoinen. Toivottavasti meiltäkin lähtee vehje jos ulkomaiden ehdokkaita tarkastellaan. Norjalalla voisi riittää mielenkiintoa lähteä mukaan tähän projektiin, jos Saab väsää oman ehdokkaan.

Periaatteessa meillä tämä voisi olla projektina mikä antaa esim mustille liikkumiskyvin jaloin, pyörin taikka telaketjujen avulla. Semi autonominen navikointi toimijoiden perässä tai vastaava.

If you remember the Ehang 184 autonomous passenger drone from CES a couple of years ago, you would be forgiven for thinking that this was yet another tech company wheeling out a headline-grabbing product that would never be seen in the real world, let alone flying across fields or over lakes.

Well, Ehang is attempting to confound the naysayers by releasing the first ever footage showing the 184 whisking actual human beings into the great blue yonder. Some 40 "passengers" were filmed enjoying their aerial excursions, including the deputy mayor of Guangzhou as well as (putting his courage where his money is) Ehang founder and CEO Huazhi Hu.

Though the footage shows the drone coping with clear and foggy conditions during flight, according to the manufacturer the 184 series is "capable of carrying a single person at up to 130km/h and in force 7 typhoon conditions".

In 2016 in Las Vegas, Ehang – a company best known for its Ghost Drone quadcopter – stated its self-navigating craft will cost between $200,000 and $300,000 (£143,000 to £241,000) and be capable of carrying single passengers of up to about 118kg for 23 minutes on a single charge. The drone itself comes in at around 200kg.

Is it a bird? Is it a plane? The prevalence of multi-rotor drones has increased dramatically in recent years, but in headwinds they pitch upwards unpredictably. Engineers from Tohoku University, Japan, have shown that angling the rotor blades of a quad-rotor unmanned aerial vehicles by just 20 degrees can reduce pitching by a quarter. Their work is published in the International Journal of Micro Air Vehicles.

Multi-rotors have gotten much smaller since the turn of the century, and they have many uses, including for inspection, surveillance and transportation. A multi-rotor setup allows for both vertical takeoff and hover in calm conditions, but they are unstable in wind. Their rotors flap and the vehicle pitches upwards in a headwind. In this experiment, Hikaru Otsuka and colleagues set out to evaluate whether angling the rotor blades differently would improve control of quad-rotor vehicles in winds.

Pitching can occur because of three factors: the drag of the body, the asymmetry induced flow distribution on the rotor with the wind, and rotor thrust difference between the front and rear rotors. The team first estimated the effects of the wake of the front rotors on the rear, then isolated the rotors from the vehicle and measured the effect of different angles in a low-speed wind tunnel.

They show that angling the rotors to the outer side by 75 degrees kept the airflow passing each rotor blade isolated, but increasing the angle to 90 or above meant the wake of the front rotors affected the rear.

Then they analyzed how this translated to a complete quad-rotor with all four rotors working together. In the wind tunnel, the team tested various angles of rotor attachment to the quadrotor and the effect on pitching moment generation. They measured the effects of outward and inward tilting of the rotor blades for five different angles. They found that rotor tilting by 20 to the outer side degrades the pitch of the vehicle by 26%.

The authors conclude that tilting of the rotors to the outer side reduces pitching moment of quad-rotor vehicles in winds. The work could have implications for both hobbyists and for professionals who want to use multi-rotor unmanned vehicles outdoor, as for inspections of wind turbines, disaster sites, or for safety of rescue activities.

Irakilainen reportaasi CH-4 droneista.

Mitäs vehjettä porukka odottaa Rangereiden tilalle? Ensi vuosikymmenellä se(kin) on edessä meinaan. Uudempaa Israelilaista? Jenkkiä?

Sveitsiläiset osti omien 15x Rangerin tilalle 6x Elbit Hermes 900. Joka on melkoisesti isompi ja kalliimpi kuin mitä Rangerit oli.

Kuuteen tärväytyi kokonaista 200 miljoonaa. Joten voipi olla aika hiljaista meidän osalta tämän valinta. Kilpaili IAI Super Heronia vastaan.

https://www.flightglobal.com/news/a...ects-hermes-900-as-ranger-replacement-400129/

Rangerihan on IAI:n ja RUAG Aviationin yhteistekoa. Eli lisenssit on Israelista, mikä tekee hankinnan suuntautumisen siihen suuntaan melko todennäköiseksi.

Veikkaan joku tuoreutettu Elbit Hermes 450:n versio.

Mikään MALE-lennokki ei sovi #metoo-Suomeen seksististen konnotaatioiden vuoksi!

No, vakavammin, Venäjää vastaan toimittaessa lennokin pitää olla joko a) selviytymiskykyinen b) halpa. Nykyiset MALE-lennokit eivät oikein täytä määritteitä. Ehkä 2020-luvulla asia on toisin. Pienet ja halvat lennokit ovat ok. Ellei sitten ole tarkoitus hankkia lennokkeja selustan valvontaan.

Jos taas puhutaan kymmenistä tai sadoista miljoonista kannattaa ennemmin hankkia satelliitteja jotka ovat vähemmän haavoittuvia ja joilla voi kerätä tiedustelutietoa myös rauhan aikana. Ihannetapauksessa vaikkapa Ruotsin kanssa yhteistyössä kustannusten säästämiseksi, mutta tarvittaessa vaikka yksin.

Satelliitit mainittu

Kannattaa lähteä miettimään mitä niillä Rangereilla on nyt tehty ja miten niistä vaateista selviydytään tulevaisuudessa. Toki tehtäväkenttä voi korvaavalla kalustolla laajentuakin.

Tekniikka on kehittynyt ja lento-ominaisuudet ovat sen myötä nykyisillä välineillä jotain aivan muuta kuin mihin Ranger pystyy. Toki sitten taas pienemmillä hyötykuormilla ei päästä ihan samalle tasolle sensorien osalta eli kauhean paljon kevyempää lavettia ei voi hankkia jos halutaan parempaa tiedustelu/maalinosoituskykyä.

Rangerin julkisin tehtävä taitaa olla Herlinin sieppaajan jahtaaminen....

Haavoittuvuus ei ole oikein vähentynyt. Rangerin tahi Hermeksen selviytyvyys on aika heikkoa ilmatorjunta- ja ilmataistelukykyistä vastustajaa kohtaan. Ei ole nopeutta, ei ole suurta korkeutta, ei ole häiveominaisuuksia. Lukumäärä on kuitenkin niin pieni, että alas ampuminen kannattaa. Tiedustelu- ja maalinosoitus ei näin ollen oikein onnistu - toki voidaan saada tieto siitä että vihollinen on ampunut lennokin alas. Tämähän tuli esille jo Georgian sodassa 2008.

Defense Secretary Jim Mattis can get ticked off at times over stilted military terminology and its blizzard of unfathomable acronyms. Last week, he let loose at one of his pet peeves.

In this case, it was "Unmanned Aerial Vehicles," or UAVs, which is what the Defense Department calls drones.

Mattis didn't propose an alternative, or say he was going to order a name change. He just wanted it known that he doesn't like the term.

"One of the most misnamed weapons in our system is the unmanned aerial vehicle. It may not have a person in the cockpit, but there's someone flying it," Mattis told reporters traveling with him on the trip back from a series of security conferences in Europe.

In addition to the person on the joystick flying the thing, "there's someone over their shoulder. There's actually more people probably flying it than a manned airplane," he said.

Then "there's all these people taking the downloads from it. There's people deciding to load bombs on it or not, or ISR cameras, surveillance cameras, on it," Mattis said.

Bottom line: "It's not unmanned," he said.

On Feb. 12th, 2018, the Iraqi ministry of defense released a video depicting its Chinese-made CH-4B armed unmanned aerial vehicles. The brief report underscores the type’s success in Iraqi service.

The video claims that the CH-4B drones have executed most of their attack and reconnaissance missions in northwest Iraq. Since their entry into operational service, they have performed no fewer than 260 air strikes against Islamic State targets, with a success rate close to 100 percent.
