STAR 48GXV Motor Will Give Boost Needed to Send Spacecraft on Path to the Sun.
为了发送航天器踏上去太阳的路途,STAR 48GXV马达将提供所需求的推动。
              
ARLINGTON, Va. — ATK (NYSE: ATK) and NASA successfully tested a proof-of-concept STARTM 48GXV motor for the Solar Probe Plus mission, which will enter the sun’s atmosphere to study the streams of charged particles the sun hurls into space. The STAR 48GXV solid-fuel third stage will provide the boost needed to assist the Solar Probe Plus spacecraft in escaping Earth’s orbit to begin its approach of the sun.
阿灵顿,弗吉尼亚州 -  ATK(纽约证券交易所代码:ATK)和 NASA成功测试了太阳探测器加任务(所用的)STARTM 48GXV马达,校验了其设想,该任务将进入太阳的大气层,来研究 太阳投掷进入空间的带电粒子流。STAR 48GXV固体燃料第三级将提供必要的协助,以辅助太阳探测器plus航天器逃离地球轨道,(然后)开始接近太阳。
                  
Solar Probe Plus is scheduled to launch in 2018 on an Atlas V rocket. ATK’s STAR 48GXV motor is based on the venerable STAR 48BV rocket, with roots dating back to the late 1970s and hundreds of successful Delta II-class missions. The new STAR 48GXV motor incorporates many new technologies, including lightweight composite case and exit cone materials, and advanced thrust vector controls.

“This test highlights ATK’s ability to design, develop and manufacture highly engineered products to support a wide range of customer needs,” said Cary Ralston, vice president and general manager, Missile Products division. “The STAR 48GXV ushers in a new performance standard for solid-propellant upper stage motors.”

With its high-strength graphite composite case, the STAR 48GXV motor can operate at approximately three times the chamber pressure of its predecessor. The filament-wound case significantly reduces the cost and lead time associated with thin-walled titanium cases. The ignition train incorporates a consumable Vespel® igniter initiated by a high voltage initiator. The exit cone, manufactured at ATK’s facility in Promontory, Utah, is a lightweight carbon-carbon structure that eliminates the need for support structures. ATK’s thrust vector electronic control system (TVECSTM), which includes electro mechanical actuators and a digital controller, is used to command the vectorable nozzle to achieve the desired thrust vector.

Solar Probe Plus Moves into Advanced Development

March 18, 2014

140318_1_sm.jpg
Technicians at the Johns Hopkins University Applied Physics Laboratory in Laurel, Md., prepare an engineering model of the Solar Probe Plus Thermal Protection System, or TPS, for vibration tests in October 2013. The main feature of the TPS is an 8-foot-diameter, 4.5-inch-thick, carbon-carbon, carbon foam shield that will sit atop the Solar Probe Plus spacecraft body. The system will protect Solar Probe Plus fr om temperatures exceeding 2,500 degrees Fahrenheit and impacts from hypervelocity dust particles as it flies through the sun’s outer atmosphere. The vibration tests simulate the shaking the spacecraft will undergo during launch; Solar Probe Plus is scheduled to launch in 2018.

Solar Probe Plus — NASA’s ambitious mission to fly through and examine the sun’s atmosphere — has reached a key stage of development.

Solar Probe Plus will begin advanced design, development and testing — a step NASA designates as Phase C — following a successful design review in which an independent assessment board deemed that the mission team, led by the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., was ready to move ahead with full-scale spacecraft fabrication, assembly, integration and testing.

“Solar Probe Plus will fly closer to the sun than any spacecraft before it — almost 10 times closer to the sun than the planet Mercury — and this presents unprecedented technical challenges,” says Andrew Driesman, Solar Probe Plus project manager at APL. “Whether it was devising ways for a spacecraft to survive so close to the sun, or to collect data in such an extreme environment, the concept of an operational solar probe had challenged engineers and scientists for decades, and now we’re another step closer to making it happen.”

Set to launch in 2018, Solar Probe Plus will orbit the sun 24 times, closing in with the help of seven Venus flybys. At its closest passes the probe will speed 118 miles per second through the sun’s outer atmosphere, or corona, coming about 3.8 million miles (about 6.2 million kilometers) from the surface to explore a region — and face hazards — no other spacecraft has encountered. Solar Probe Plus will carry 10 science instruments specifically designed to help solve two key puzzles of solar physics: why the sun’s outer atmosphere is so much hotter than the sun’s visible surface, and what accelerates the solar wind that affects Earth and our solar system.

“The answers to these questions can be obtained only through in-situ measurements of the solar wind down in the corona,” says APL’s Nicky Fox, Solar Probe Plus project scientist. “Solar Probe Plus gets close enough to provide the missing links, with the right complement of instruments to make the measurements. For the first time, we will be able to go up and touch our star.”

APL, which manages the mission and leads the spacecraft fabrication and integration effort, has made significant progress on several enabling technologies, such as the carbon-carbon composite heat shield that will protect Solar Probe Plus from temperatures exceeding 2,500 degrees Fahrenheit and impacts from hypervelocity dust particles. Engineers have also built and tested a liquid-cooling system to keep the spacecraft’s solar arrays at safe operating temperature throughout the voyage, and spacecraft parts are undergoing high-velocity dust tests that simulate flights through swarms of high-energy particles near the sun.

“Solar Probe Plus is a pathfinder for voyages to other stars and will explore one of the last unexplored regions of the solar system, the solar corona, wh ere space weather is born,” says Lika Guhathakurta, Solar Probe Plus program scientist at NASA Headquarters in Washington.

The Solar Probe Plus team includes engineers, scientists, technicians and other experts from government, academia and industry. The mission is part of NASA’s Living With a Star program, designed to learn more about the sun and its effects on planetary systems and human activities. NASA’s Goddard Space Flight Center in Greenbelt, Md., manages the program for the Science Mission Directorate at NASA Headquarters.

题外话,应用物理实验室(APL)正在进行的几个探测项目都很有特点,目的地不是离太阳很近(Messenger和Solar probe plus),就是离太阳很远(New Horizons)

Solar probe plus的发射载具已从Atlas V 551换成了Delta IV-H,以便留出足够的重量余量
The launch energy is much higher than most interplanetary missions and requires a powerful three-stage launch system. The maximum launch C3 over the 20-day launch period is 154 km2/s2. The baseline launch system is an EELV (Evolved Expendable Launch Vehicle) Delta IV Heavy class launch vehicle with a standard Star 48 BV upper stage. During the Phase B development, an EELV Atlas V 551 launch vehicle was assumed. The recent switch to the more powerful Delta IV Heavy  class launch vehicle will allow for more launch mass and increase spacecraft mass margin for the Phase C development.

真够贵的了,这样看来以后深空探测器用SLS发射也不奢侈,用D4H发射能比551快吗?

执行NASA太阳探测附加任务(Solar Probe Plus,SPP)的新航天器将在防护罩的保护下,以前所未有的近距离接近太阳,进入太阳大气层收集数据,预计不迟于2018年发射。

新航天器像一辆轿车般大小。接近太阳时,它的碳复合热防护罩必须能经受得住超过2550华氏度(约1399摄氏度)的高温和剧烈的辐射爆炸。航天器将到达距太阳表面约400万英里(约644万公里)处,穿越其大气层。其他航天器从未到达过距离太阳如此近的距离,可帮助在未来的太空探索中更好地理解、描绘并预测辐射环境。

多了一个三级,另外Delta IV-H还需要通过NASA的评审。

也是7次金星引力弹弓,不会比 Atlas V-551快,AV发射的重量余量不够,所以才换DIVH

美宇航局拟首次派遣飞船进入太阳上层大气层
  
  2015年04月10日   新浪科技
     
      美国宇航局决定实施一项雄心勃勃的任务,发射“太阳探测器PLUS”进入太阳上层大气层,与太阳上演从未有过的亲密接触。太阳探测器PLUS携带4个实验装置,将进入日冕研究太阳风和高能粒子。在与太阳之间的距离达到最近时,太阳探测器PLUS外部的温度将接近2500华氏度。

     美国宇航局决定实施一项雄心勃勃的任务,发射“太阳探测器PLUS”进入太阳上层大气层,与太阳上演从未有过的亲密接触。太阳探测器PLUS携带4个实验装置,将进入日冕研究太阳风和高能粒子。在与太阳之间的距离达到最近时,太阳探测器PLUS外部的温度将接近2500华氏度。
   
     太阳探测器PLUS将搭乘“联合发射联盟”公司的德尔塔4型重型火箭从佛罗里达州的卡纳维拉尔角空军基地发射升空。发射窗口为20天,从2018年7月31日开始。太阳探测器PLUS将环绕太阳24周。前往太阳过程中,这颗探测器将7次飞越金星,缩短与太阳之间的距离。最近时,太阳探测器PLUS与太阳表面的距离只有380万英里(约合610万公里)。

    太阳探测器PLUS将搭乘“联合发射联盟”公司的德尔塔4型重型火箭从佛罗里达州的卡纳维拉尔角空军基地发射升空。发射窗口为20天,从2018年7月31日开始。太阳探测器PLUS将环绕太阳24周。前往太阳过程中,这颗探测器将7次飞越金星,缩短与太阳之间的距离。最近时,太阳探测器PLUS与太阳表面的距离只有380万英里(约合610万公里)。

  长久以来,科学家便希望派遣一颗探测器穿过太阳的外层大气层,也就是日冕,进一步了解太阳风以及被太阳风带入太阳系的物质。太阳探测器PLUS的首要目标是追踪能量流和研究日冕的加热机制,同时研究加速太阳风和高能粒子的物理机制。为了完成这些目标,太阳探测器PLUS将携带4个实验装置进入日冕,对日表喷射的太阳风和高能粒子进行研究。这些装置将研究磁场、等离子体和高能粒子,同时对太阳风进行成像。

  太阳探测器PLUS以及所搭载的仪器受到4.5英寸(约合11厘米)厚的防护罩的保护。防护罩采用碳纤维复合材料制造,保护探测器免遭太阳散发的热量侵袭。在与太阳之间的距离达到最近时,太阳探测器PLUS外部的温度将接近2500华氏度。这颗探测器的体积与一辆小汽车相当,将直接钻入太阳大气层,与日表之间的距离只有400万英里(约合645万公里)左右,探索其他任何探测器从未进入的区域。

  太阳探测器PLUS将和太阳进行前所未有的亲密接触,超过以往的其他任何探测器。3月,这项任务成功完成关键设计评估,实现一个重要的里程碑。3月16日至20日,美国宇航局的一个独立评估委员会在约翰斯-霍普金斯大学的应用物理学实验室会面,对太阳探测器PLUS任务的各个方面进行评估。应用物理学实验室负责为宇航局设计制造和操作太阳探测器PLUS。关键设计评估结果显示太阳探测器PLUS的设计已达到非常先进的程度,探测器的制造和组装工作以及系统集成和任务各方面的测试工作可能在不久后展开。(孝文)
