JET PILOTATI A DISTANZA...NUOVA FRONTIERA DEI DRONI


di: Dott. Giuseppe Cotellessa (ENEA)

Il procedimento del brevetto può risultare molto utile in quest’applicazione

F-16 senza pilota, test della Boeing negli USA

L’obiettivo del test è verificare se il jet possa essere essere pilotato a distanza

Un F-16 andato in “pensione” 15 anni fa dall’Air Force è tornato a volare, ma stavolta senza pilota, grazie alla Boeing. In una base militare della Florida sono stati effettuati alcuni test per verificare se il velivolo possa essere usato come drone. In realtà il primo volo di un caccia Lockheed Martin è stato effettuato la scorsa settimana anche se solo oggi è stata data la notizia dal colosso americano. Due piloti dell’aeronautica militare americana hanno pilotato l’aereo in remoto, da terra, ed il jet ha volato nel Golfo del Messico.


                         Il volo dell’F-16 senza pilota

Dopo i tanti anni passati a prendere la polvere in Arizona, il vecchio F-16 ha volato fino a toccare i 12.000 metri di quota a circa 1.800 Km/h (Mach 1,47) effettuando numerose evoluzioni ed acrobazie, un avvitamento, una “split S” (il volo capovolto a testa ingiù) prima di tornare verso la base militare di partenza. Boeing ha fatto sapere che l’F-16 senza equipaggio è stato scortato da altri due velivoli per questioni di sicurezza. Il jet era inoltre dotato della strumentazione per l’autodistruzione, in caso di necessità. Il costruttore ha inoltre comunicato di avere a disposizione sei velivoli F-16 ormai fuori servizio, modificati e rinominati QF-16, che la Difesa Usa è pronta a utilizzare per nuovi test.

Flying Drone Captures Underwater Images of 300-Year-Old Coral

coral mapping

A tiny flying drone has captured gorgeous images of 300-year-old coral off the coastline of Ofu Island.


A flying drone the size of a shoebox has captured astonishingly detailed images of 300-year-old coral living beneath the waters off American Samoa in the South Pacific.

The new technology could allow scientists to map the world's coral reefs, enabling scientists to predict their health and the health of the ecosystems that the reefs anchor.

"These corals are time machines that were living before European culture discovered the Samoan Islands," Stephen Palumbi, a researcher at the Stanford Woods Institute, who helped conduct the drone study said in a statement. "What do they have to tell us about that long-ago time? What do they tell us about the likely future?"

Coral reefs sustain about a quarter of all marine life and are shelter for more than 4,000 species. The fish that live within coral reefs are an important food staple for about 500 million people around the world.

Yet despite their crucial role in the marine ecosystem, coral reefs are mostly unmapped. Hand-mapping or photographing reefs is incredibly tedious, time-consuming and potentially inaccurate, while satellite imagery gets muddled by waves. Radar can't penetrate the water's surface and sonar fails in shallow areas.

To get around these limitations, Palumbi and Stanford aeronautics graduate student Ved Chirayath developed a tiny, remote-controlled drone that can film coral reefs from up to 200 feet (61 meters) above the ocean.

But ripples on the water create distortion and blur that make the drone images difficult to interpret. So after the images were gathered, Chirayath used a technique called fluid lensing to digitally remove those distortions and sharpen the images.

"The lensing takes a huge problem in looking through the surface of the water and turns it into an advantage," Palumbi said. "It not only removes the ripples, but uses their magnification to enhance the image," he added, referring to the fact that objects underwater tend to appear closer than they are because of how light bends when it moves from air to water.

The researchers then used a 360-degree camera to photograph the reefs from underwater.

Combining the images from both the drone and the underwater camera, the team produced gorgeous panoramic images of the reefs surrounding a marine protected area in American Samoa around Ofu Island.

The corals, some of which are 15 to 20 feet (4.5 to 6 m) wide, live in a reef called the "Village of Elders" that seems perfectly suited to these ancient corals.

As a follow-up, the team plans to combine data on water temperature and water flow with the images to see how climate change alters the reef ecosystem.

THE FIRST FLYING CAR IS FINALLY HERE, GOES ON SALE 2015- IT CAN TAKE OFF VERTICALLY IN TRAFFIC JAM!



The first flying cars are set to go on sale to the public as early as 2015.

Terrafugia has announced its Transition design, which is part sedan, part private jet with two seats, four wheels and wings that fold up so it can be driven like a car, will be on sale in less than two years. The Massachusetts-based firm has also unveiled plans for a TF-X model that will be small enough to fit in a garage, and won’t need a runway to take off. Would you buy one?
