Edwards AFB CA (SPX) Nov 29, 2011
Northrop Grumman and the U.S. Navy will be able to increase the pace and productivity of the X-47B flight test program following the successful first flight Nov. 22 of the second air vehicle developed for the Navy's Unmanned Combat Air System Carrier Demonstration (UCAS-D) program.
The tailless, autonomous aircraft known as Air Vehicle 2 (AV-2) took off under hazy skies from Edwards Air Force Base at 12:43 p.m. PST, climbed rapidly to an altitude of 5,000 feet, flew several racetrack patterns over Rogers Dry Lake, then landed safely at 1:12 p.m.
"The successful addition of AV-2 to the fleet of X-47B test aircraft provides a critical inflection point for the UCAS-D program," said Carl Johnson, vice president and UCAS-D program manager for Northrop Grumman's Aerospace Systems sector.
"With two aircraft now available, we can increase the amount of aircraft performance data we gather, which will allow us to meet our required aircraft capability demonstration goals in a timely manner."
The availability of two test aircraft is particularly important, added Johnson, for helping the program maintain a satisfactory flight test rhythm as it begins transitioning X-47B aircraft to Naval Air Station Patuxent River, Md., (Pax River) for shore-based carrier suitability testing.
While one aircraft is being moved to Pax River - expected to occur by the end of 2011 - the other one will continue envelope expansion flight testing at Edwards.
The testing at Pax River is scheduled to begin in early 2012. It will include testing the X-47B's ability to conduct precision approaches to the carrier, and to perform arrested landings and "roll-out" catapult launches at land-based test facilities.
The testing will also include flight testing precision navigation computers and new guidance, navigation and control software recently installed on both aircraft. The new suite of hardware and software will enable the X-47B to make precision landings on a moving carrier deck.
The X-47B is a computer-controlled unmanned aircraft system that takes off, flies a preprogrammed mission, and then returns to base - all in response to mouse clicks from a mission operator.
The operator actively monitors the X-47B air vehicle's operation using simple situational awareness displays, but does not fly it via remote control, as some unmanned systems are operated.
The Navy awarded the UCAS-D prime contract to Northrop Grumman in August 2007. The contract calls for the development and flight testing of two strike-fighter-sized X-47B unmanned aircraft.
In 2013, the program is scheduled to demonstrate the first carrier launches and recoveries by a tailless, unmanned, low-observable-relevant aircraft. Autonomous aerial refueling demonstrations are planned for 2014.
Northrop Grumman's UCAS-D joint industry team includes GKN Aerospace, Lockheed Martin, Pratt and Whitney, Eaton, General Electric, Hamilton Sundstrand, Dell, Honeywell, Goodrich, Moog, Wind River, Parker Aerospace and Rockwell Collins.

Come Home X-37B
Sydney, Australia (SPX) Nov 26, 2011
At the end of November, the mysterious X-37B robot spaceplane will reach a critical point in its mission. This time will mark the end of the official 270-day endurance limit of the semi-secret military shuttle. The X-37B could be getting ready to come home. But will it? Let's rewind and review what this is all about. The X-37B is a small, experimental winged spacecraft operated by the US A ... read more
