L'argomento sembra interessante, aprirei una discussione ad hoc per questo giocattolino http://www.naval-technology.com/projects/x-47b-unmanned-combat-air-system-carrier-ucas/ X-47B Unmanned Combat Air System Carrier (UCAS) The X-47B is an unmanned combat air system carrier (UCAS) being developed by Northrop Grumman for the US Navy (USN). The strike fighter size unmanned aircraft is currently in its demonstration phase. The unmanned aircraft was first developed as part of the X-47 programme. Air worthiness of the X-47B unmanned combat air system demonstrator was developed at an estimated cost of $813m. The aircraft performed a successful initial test flight at Patuxent River, Maryland, in July 2012. The X-47B is expected to enter active naval service by 2019. Development history of the UCAS-D "The X-47B UCAS was developed by the US Navy as part of the unmanned combat air system carrier demonstration (UCAS-D) programme." The X-47B UCAS was developed by the US Navy as part of the unmanned combat air system carrier demonstration (UCAS-D) programme. The programme aims to develop and demonstrate which fighter sized tailless unmanned aircraft can be deployed from US Navy aircraft carriers. The X-47B is a variant of Pegasus X-47A which was developed as a joint USAF and USN programme, called J-UCAS, in 2001. The programme was funded by the DARPA with Northrop Grumman as the main contractor. In February 2006, however, the Joint-UCAS development programme was cancelled for separate UAV development programmes by both the defence forces. Development of the X-47B, which had started in June 2005, was temporarily halted following the cancellation. The US Naval Air Systems Command (NAVAIR) contracted Northrop Grumman for the construction and demonstration of two X-47B aircraft under the unmanned combat air system demonstrator (UCAS-D) programme, in August 2007. The UCAS-D programme also aims to pave the way for developing potential future carrier-compatible, unmanned systems with little risk. Companies collaborating on the UCAS-D programme include Rockwell Collins, Goodrich, Lockheed Martin, Parker Aerospace, Honeywell, GKN Aerospace, General Electric (GE), Wind River, Dell, Hamilton Sundstrand, Pratt & Whitney, Eaton and Moog. Design and features of the X-47B The tailless unmanned aircraft is 38.2ft long and has a wingspan of 62.1ft. The shape of the aircraft is designed for stealth or low observable relevant requirements. The weapons bay can carry 4,500lb of weapons. Operations of the computer-controlled X-47B UCAS are smart and its flight control system is autonomous. The navigation of the UCAS is controlled by hybrid global positioning system (GPS) vision-based system. The flight path is preprogrammed and its operations are monitored by a mission operator. The UCAS is equipped with electro optics (EO), infrared (IR), synthetic aperture radar (SAR), inverse SAR, ground moving target indicator (GMTI), electronic support measures (ESM) and maritime moving target indicator (MMTI) sensors. The UCAS-D will feature both probe-and-drogue of the US Navy and boom-receptacle mechanisms of the USAF for autonomous air refuelling. X-47B engine and performance details The X-47B is powered by a Pratt & Whitney F100-PW-220U engine and exhaust system. The aircraft has a high subsonic speed of about 0.45M and range of about 2,100nm. The UCAS can fly to a maximum altitude of 40,000ft. Testing of the X-47B demonstration aircraft "The X-47B is powered by a Pratt & Whitney F100-PW-220U engine and exhaust system." Two autonomous jet-powered X-47B aircraft were built under the UCAS-D programme. The two demonstration vehicles have similar design and hardware features, however, only one is equipped to test aerial refuelling tasks. They can accommodate various kinds of sensors for reconnaissance, intelligence and surveillance and have space for weapon systems. Payload is not installed on the demonstration units. The first X-47B, including structural proof testing, was completed by October 2009. Named air vehicle 1 (AV-1), the aircraft was transferred to Edwards Air Force Base (AFB) for flight testing in July 2010. The second aircraft, named AV-2, arrived at the base for testing in March 2011. The first flight test of the UCAS-D was conducted in February 2011. The first catapult launch of X-47B was conducted at an onshore catapult facility at Naval Air Station Patuxent River in November 2012. The first at-sea test phase involving a series of deck handling trials aboard the USS Harry S. Truman (CVN 75) was completed in December 2012. The aircraft will also be tested for launching, operating and recovering capabilities in a navy carrier operable area of 50nm. The carrier launch, recovery, and deck handling tests are scheduled for 2013. The aerial refuelling demonstrations will be carried out in 2014. 1.8 miliardi di dollari e soli 8 anni di sviluppo... io non credo che sostituiranno mai completamente i caccia, però come piattaforme d'attacco imho sono il futuro. questo UCAV può portare due bombe a guida satellitare da 900Kg a 1280 Km di distanza... non ha pilota, costa molto meno di un F-35 ed è stealth.... ripeto, in soli 8 anni di sviluppo http://en.wikipedia.org/wiki/Northrop_Grumman_X-47B
Direttamente dalla pagine Instragram di Renault e di TheArsenale, alcune immagini ed un video teaser per quella che sarà la Renault R4 Concept che verrà presentata il 26 Novembre. Il nome ufficiale non si sa ancora quindi ho messo R4 Concept nel titoto. 255639641_418389286508865_5570548520493234848_n.mp4 ---- Renault and TheArsenale unveil AIR4: where we are going, we don’t need roads AIR4, A FLYING SHOWCAR INSPIRED BY THE ICONIC RENAULT 4 FOR ITS 60TH ANNIVERSARY To conclude the celebrations for the 60th anniversary of Renault 4, the car maker has decided to team up with motion design hub TheArsenale to create a futuristic showcar, reinterpretation of this iconic model. 2021 marks the 60th anniversary of Renault 4L, a car that has sold more than 8 million units in over 100 countries over a period of more than 30 years. Much more than a car, 4L is a true icon. To celebrate its 60th anniversary, Renault has been holding a year of celebrations consisting of a number of initiatives. To wrap it up, the brand decided to join forces with the ground-defying design hub TheArsenale to create a showcar that gives a futuristic and offbeat reinterpretation of 4L. The original Renault 4 was a simple, efficient and versatile vehicle built between 1961 and 1992. A “blue jeans” car, as the former head of Renault Group, Pierre Dreyfus, used to describe it. A true icon conveying families, businesses and the likes of the gendarmerie and La Poste, as well as helping several generations of young motorists get behind the wheel. Its values and qualities convinced TheArsenale to collaborate with Renault to reimagine a 4L designed to drive along the unmarked highways above our heads. AIR4, THE RENAULT 4 “VOLANTE” Renault has partnered with TheArsenale on this truly unique project, and the result is unprecedented. AIR4 is a symbol of independence and freedom, born out of the realisation that traffic is compounding, lives are grinding to a halt, and the world above us is unhampered. Thus, AIR4 claims the air as the new road of the future. Design wise, AIR4 has resulted in a reinterpretation of the retro icon by TheArsenale, far from the modern car design language. The vehicle, entirely made of carbon-fiber, maintains the same lines and contained mass of the original 4L, yet presenting new dynamic capabilities. The rigidity has been completely revised to include new concepts such as thrust or lift, which required hours of calculations and tests. Drawing on generative design techniques using artificial intelligence, TheArsenale’s engineers were able to test terabytes of data to improve and fine-tune the designers' ideas, even before starting the first real-world trials. After a year-long of celebration we wanted to create something unconventional to close up the 60th anniversary of 4L. highlights Arnaud Belloni, Renault Brand Global Marketing Director. This collaboration with TheArsenale was a natural fit. The flying showcar AIR4 is something unseen yet and a wink to how this icon could look like in another 60 years. To drive around, AIR4 has no wheels. Instead, it features four two-blade propellers, one at each corner of the vehicle. The chassis sits in the middle of the rota frame, and the driver can access and take a seat in the utilitarian cabin of the vehicle by lifting the reimagined Renault 4 shell, which is hinged at the front. From a technical standpoint, AIR4 is powered by 22,000 mAh lithium polymère batteries that generate a total power of 90,000mAh. The vehicle counts on an orizontal top speed of 26m/s, with a 45° inclination during flights, and up to a maximum inclination of 70°. It can fly as high as 700m with a take off speed of 14m/s, restained at 4 m/s for safety reasons, and landing velocity of 3 m/s. Last but not least, AIR4 offers a maximum vectorial thrust of 380 kilograms, that is to say 95kg per propeller. AIR4 has been imagined, designed, engineered and assembled entirely in France, in the heart of Europe’s first technology park in Sophia Antipolis, on the Côte d’Azur. THEARSENALE “ROAD TO AIR” TheArsenale stands by the assumption that the icons of car culture are eternal. This vehicle is the first product from TheArsenale’s ROAD TO AIR division, which envisions the future transport network to be in the sky. AIR4 is the brainchild of Patrice Meignan, CEO and Founder of TheArsenale, who sought to create a new kind of vehicle that provokes emotion, establishes brand identity and offers pleasure. I have dedicated my life to the passion for mobility and I continually explore all aspects of the moving world. says Patrice Meignan. After 25 years of forward-looking research, we believe that the icons of car culture are eternal, whether on earth or in the air. For 60 years, Renault 4 has been driven by ordinary people who make it extraordinary. It is a car that symbolises adventure: simple, practical, useful and as modern as it is retro. Most drivers will tell you, it allows you to travel differently and to live an adventure. This ‘traveling different’ has inspired my team and I. With AIR4 by TheArsenale, the Renault 4 is ready for one of its greatest adventure yet. WORLD PREMIERE After its digital presentation today, 26th of November, AIR4 will go on public display from next Monday until the end of the year in the vibrant center of Paris at the Atelier Renault on the Champs Elysées, alongside other historic versions of the Renault 4. Beginning 2022, AIR4 will hit the American ground in Miami and then New York, before a pit stop in Macau.
Soluzione semplice... li segui fino al primo semaforo rosso con uno di questi. Versione con camera integrata e trasmissione video su smartphone via Wi-Fi - scatta a 14MP in RAW, c'è il profilo lente per togliere la distorsione del grandangolo, e si possono utilizzare i filtri da 46mm. La camera non è il massimo della vita ma probabilmente puoi fartela bastare... O ancora meglio (ma c'è da spendere di più) Versione con gimbal brushless per la GoPro 3/3+, a cui si può aggiungere il sistema di trasmissione video e telemetria a terra, su display da agganciare al telecomando.
Visto che spesso al posto di "contar le pecorelle" uso morbosamente Flightradar24 per addormentarmi Una sera ho beccato un drone in volo... Secondo me però qualcosa non quadrava: distanza percorsa e tempo di volo, anzitutto. Un DJI MAVIC PRO ha un'autonomia inferiore ai 30 min ed un raggio d'azione di qualche km... Di che diavolo si trattava allora? Errore di codifica di qualche tipo?
