The Navy’s X-47B Unmanned Combat Air System (UCAS) demonstrator completed its first-ever arrested landing here May 4, another key step to mature the system for its historic carrier-based tests later this month.
“Landing an unmanned aircraft on an aircraft carrier will be the greatest singular accomplishment for the UCAS demonstration and will serve as the culmination of over a decade of Navy unmanned carrier integration work”, said Capt. Jaime Engdahl, Navy UCAS program manager. “Shore based arrested landing testing here at NAS Patuxent River is our final check that the X-47B can meet that objective.”
During Saturday’s test, the X-47B used a tailhook on the aircraft to catch a carrier representative cable, known as the MK-7 arresting gear, to quickly stop the aircraft. This is known as an arrested landing, the type of recovery required aboard aircraft carriers. The MK-7 arresting gear is an underground installation of actual carrier equipment that accommodates structural tests and aircraft/arresting gear compatibility studies with all models of U.S. Navy carrier aircraft.
“Shore-based testing allows our combined Navy/Northrop Grumman team to control test conditions before taking the aircraft to the ship,” said Matt Funk, Navy UCAS test team lead. “We are gradually building up to the maximum load conditions we expect to see during an arrested landing aboard an aircraft carrier.”
This month the aircraft will undergo sea-based carrier testing, catapulting from the carrier deck and potentially completing landings aboard USS George H.W. Bush (CVN 77).
“The entire system has performed very well across a large set of shore-based testing events including aircraft performance, flying qualities, navigation performance, catapult launches, and precision landings designed to stress system operation,” Engdahl said. “Our final carrier-landing software simulation shows excellent performance, flight test results are very good, and we are confident the X-47B will perform well on the ship.”
The X-47B is a tailless, autonomous aircraft designed with unique features for an unmanned aircraft, such as carrier suitable landing gear and structure. While the X-47B itself will not be used for operational use, the UCAS-D program is developing a concept of operations and demonstrating technologies for use in follow-on unmanned carrier based aircraft programs.
“This actual demonstration of the X-47B unmanned carrier operations is a first, essential step toward developing a carrier-based unmanned system for the U.S. Navy,” said Rear Adm. Mat Winter, who leads the Program Executive Office for Unmanned Aviation and Strike Weapons. “A carrier-based unmanned aircraft will increase carrier strike group relevance, provide opportunities for training and readiness cost avoidance and enable our future forward deployed carrier air wings to provide continuous intelligence, surveillance and reconnaissance capability.”

Drone is catapulted off aircraft carrier in milestone flight test


By W.J. Hennigan, Los Angeles Times
May 15, 2013

In a historic feat for the U.S. Navy, a stealthy bat-winged drone was catapulted off an aircraft carrier's flight deck before it soared above the Atlantic and into the blue sky.

On Tuesday morning, the X-47B experimental drone was launched from the nuclear-powered aircraft carrier George H.W. Bush as it floated off the Virginia coast.

The test flight was seen as a milestone in drone technology and the program, which has been eight years in the making.

"Today we saw a small but significant pixel in the future picture of our Navy as we begin integration of unmanned systems into arguably the most complex war-fighting environment that exists today: the flight deck of a nuclear-powered aircraft carrier," Vice Adm. David Buss, commander of naval air forces and known as the Navy's "air boss," said in a statement.

The radar-evading drone was launched from the deck at 11:18 a.m. Eastern time. It executed several maneuvers designed to simulate tasks that the aircraft would have to perform when it lands on a ship. Then, after about 65 minutes of flight, the Navy said the drone safely flew across Chesapeake Bay to land at Naval Air Station Patuxent River in Maryland.

The X-47B, built by Northrop Grumman Corp., is designed to land on the deck of an aircraft carrier — one of aviation's most difficult maneuvers — but that was not part of Tuesday's test.

Carl Johnson, Northrop's X-47B program manager, compared Tuesday's launch with "the Navy's first catapult of a manned aircraft, which occurred in Nov. 1915 from the armored cruiser USS North Carolina. We are delighted to help launch this new era of naval capability."

The Navy has said it expects the X-47B to land on a carrier this year, relying on pinpoint GPS coordinates and advanced avionics. The carrier's computers digitally transmit the carrier's speed, crosswinds and other data to the drone as it approaches from miles away.

The X-47B's technology could mark a paradigm shift in warfare because the drone is capable of autonomous flight.

Currently, combat drones are controlled remotely by a human pilot. But the X-47B is designed to carry out a combat mission controlled entirely by a computer. A human pilot would design its flight path and send it on its way; a computer program would guide it from a ship to the target and back.


What also sets this drone apart from most of today's combat drones is that it is stealthy and jet-powered.

The X-47B, which resembles a miniature B-2 stealth bomber, has a 62-foot wingspan and can fly higher than 40,000 feet. It has a range of more than 2,400 miles and can reach high subsonic speeds.

The drone is designed to fly farther and stay in the air longer than existing aircraft because it does not depend on a human pilot's endurance. Navy fighter pilots may fly missions that last as long as 10 hours. Current drones can fly for three times that long.

The X-47B is an experimental jet — that's what the X stands for — and is designed to demonstrate new technology, such as automated takeoffs, landings and refueling. The drone also has a weapons bay with a payload capacity of 4,500 pounds, but the Navy said it has no plans to arm the aircraft.

The first X-47B had its maiden flight from Edwards Air Force Base in 2011, where it continued testing until last year when it was trucked from the Mojave Desert to Naval Air Station Patuxent River. The drone's design was so startling that motorists passing it by on the highway thought it was a UFO.

Over the last year, the Navy conducted shore-based catapults at Patuxent River, Md. It also conducted deck-handling and ship-integration testing to demonstrate the capability to safely operate the X-47B on an aircraft carrier flight deck.

There were two X-47Bs developed and built under a contract that has escalated to $1.4 billion. They were constructed behind barbed-wire fences and double security doors at Northrop's expansive facility in Palmdale.

The Navy currently flies MQ-8B Fire Scout helicopter drones, also built by Northrop, but their range is more limited and the aircraft are far slower. The Navy wants to buy a fleet of fixed-wing drones within the next seven years.

Pretty impressive stuff the drone era has taken another leap.

Much less time than it will take for you to make your failed Kaveri engines and LCA. Kid, go make your own weapons before coming here and trash talking us. India is in the lowest rung of military developments. Everything in your military is imported due to your incompetence at making your own weapons. Without imports, you won't have a military. Yes, its that bad :lol:

you get burned easily.... lol we don't need much ground work for it... unlike India, chyna keep it's failed projects secretly ... so you are safe...

You have no capability to make your own weapons. That's the real reason. Too dumb :lol:

Put a man into space kid, then come talk to us.

I don't need to build weapons... i am not interested in smuggling ....

You need Intelligence to make your own weapons.

i am afraid to say... am an electrical engineer and doing part time research on maglev, right now studying about Ybacu super conductor... i can only make an bow and arrow...

don't reply to those trolls. They only knows how to reverse engineer and hacking others data
