X-47B Demonstrator Flies in Cruise Mode for First Time
The U.S. Navy/Northrop Grumman X-47B Unmanned Combat Air System Demonstration aircraft reached a major milestone Sept. 30 when it retracted its landing gear and flew in its cruise configuration for the first time.
The flight, conducted at Edwards Air Force Base, also helped validate precision navigation hardware and software that will allow the X-47B to land with precision on the moving deck of an aircraft carrier.
"Last week's flight gave us our first clean look at the aerodynamic cruise performance of the X-47B air system...and it is proving out all of our predictions," said Janis Pamiljans, vice president and Navy UCAS program manager for Northrop Grumman's Aerospace Systems sector.
"Reaching this critical test point demonstrates the growing maturity of the air system, and its readiness to move to the next phase of flight testing."
The recent flight was part of an on-going "envelope expansion" program for the first of two X-47B aircraft produced by Northrop Grumman for the Navy's Unmanned Combat Air System Carrier Demonstration (UCAS-D) program.
Envelope expansion flights are used to demonstrate aircraft performance under a variety of altitude, speed and fuel load conditions.
The UCAS-D program plans to begin transitioning aircraft to Naval Air Station, Patuxent River, Md. in late 2011 to begin shore-based carrier suitability testing in 2012.
The focal point of the program is to demonstrate in 2013 the first aircraft carrier launches and recoveries by a tailless, low-observable-relevant unmanned system.

不爽
.......咱沈飞是不是有个类似的东西
.......咱沈飞是不是有个类似的东西真漂亮 是个好飞机 Northrop Grumman出品必是精品
沈飞三只小鸟等到花都卸了木都枯了石都烂了
这东西不错
看得眼馋!!!
口水。。。。。。
这玩意儿不错
后面几张是模型 就一个外壳
这飞机还没服役，就展示了。开放。
空战能不能达到中等飞行员的水平
有空战能力么？
……这么多钓鱼的呢
谁能翻译一下？？
羡慕嫉妒恨
最后一图是模型吧。
大号的遥控飞机？
这东西不错，以后美国大兵再被包围了，可以用这个来空投补给
不知道其他国家啥时候能搞出来
彻底崩溃了，差得太远了
翼展比F117大不少
是个好飞机
沈飞，不要让我们失望啊
我们的鸡鸡呢？？？！！！
土鳖自己的全球定位系统还没组件完呢！这个还早呢！
能让人围观 美国军迷幸福
真是不喜欢这个外形……
成飞加油能做成，可惜现在没精力。
TG马上就有了，莫急
