    洛克希德·马丁公司开发的联合战斗机 X-35B 在美国加州爱德华空军基地展示了同次飞行中向STOVL 模式的转变且保持超音速飞行。
    该机爬升到9000英尺时,推进系统成功地达到了180节,然后加速至1.08马赫,这是JSF飞机首次在同次飞行中实现了向STOVL模式的转变且保持超音速度。
    此飞机在2500英尺高空,94华氏度下完成了垂直起飞,盘旋和降落的任务。
    洛克希德·马丁公司正在和波音公司竞争为美国和英国制造JSF机型,美国政府将在今年秋天决定采用哪家公司的产品
    洛克希德·马丁公司的联合攻击战斗机X-35短程起飞和垂直降落验证机7月16日以成功地在爱德华空军基地垂直降落而完成了它的政府要求的试验。
    试飞员Simon Hargreaves说,X-35B验证机在性能上没有任何瑕疵,它进行了短程起飞,由悬停(wingborne)至水平飞行(airborne)的过渡和垂直降落。垂直降落极平稳,它是周末飞行试验的最后一项,飞机以其短程起飞和垂直降落系统连续地取得比较低的飞行速度。
    洛克希德·马丁公司计划继续进行X-35B验证机的试验。来自美海军陆战队和英国空军的飞行员将最早在本周在此飞机上作某些其它试验。
    X-35B验证机使用了一种非常有特色的推进系统。此系统的发动机为普拉特·惠特尼公司的JSF119-611。发动机的传动轴驱动罗尔斯·罗伊斯公司的对转起升风扇,在短程起飞和垂直降落操作期间产生冷空气升力。
    洛克希德·马丁公司已与诺思罗普·格鲁曼公司和BAE系统公司结伙来与波音公司竞争联合攻击战斗机的合同。此合同预计在今年10月签署。联合攻击战斗机预计用于美海军陆战队、英国空军和海军。
    仅美国五角大楼就想在以后的几十年中采购此机多达3000架,总合同额达5000亿美元。
      
      
    X-35B Vertical Landing from Wingborne Flight
    The supersonic Lockheed Martin Joint Strike Fighter X-35B made a successful short takeoff, transitioned back from wingborne to jetborne flight and made a picture-perfect vertical landing at Edwards Air Force Base on July 16, 2001.
    The soft touchdown followed a series of weekend flights in which the X-35B achieved successively slower speeds with its short takeoff/vertical landing (STOVL) system activated. The aircraft also executed several successful short takeoffs and slow landings.
    Again, the X-35B performed flawlessly, and the vertical landing was extraordinarily smooth and easy, said Simon Hargreaves of BAE SYSTEMS, chief test pilot for the X-35B. We were in familiar territory, since we had already demonstrated the airplane s solid and stable hovering ability numerous times last month. The aircraft s shaft-driven lift fan propulsion system produces enormous amounts of power, even in the California desert with its high elevation and hot temperatures.
    We also found that our vertical propulsion system provides a tenfold decrease in the hot exhaust that an aircraft reingests, as compared to other vertical propulsion systems. All this gives you a real safety margin during vertical operations.
    Late last month, the aircraft completed 17 vertical takeoffs, hovers and vertical landings at the Lockheed Martin plant in Palmdale, Calif. On July 9, it performed a STOVL conversion, a mid-air refueling and supersonic dash in the same flight.
