NASA寻求“猎户座”试飞计划的载人上面级备选方案

新闻发布时间:2012-01-19

  [据美国航天新闻网2012年1月13日报道] 美国国家航空航天局(NASA)公开征询“猎户座”(Orion)深空太空舱试验飞行所需的火箭上面级,以将“猎户座”太空舱推到低地轨道以外。这为发展备选的载人航天发射能力敞开了大门,将促进尚缺乏经验的新兴研发机构研制商业乘员太空飞船。
  
  1月9日,NASA为过渡型低温推进级(ICPS)公开寻求供应商。ICPS将用于“猎户座”多用途乘员飞行器的两次演示验证飞行,计划飞到国际太空站所在轨道以外的目的地。定于2017年12月的首次发射将是无人的,但2021年的第二次发射将搭载宇航员。两次都很可能进行绕月试飞。有意参与此项计划的供应商需在2月7日前做出回应NASA计划在9月30日前发布方案征询书。
  
  ICPS寻求供应商征询书(Sources Sought Solicitation)显示:NASA希望第一个上面级在2016年交付至肯尼迪航天中心,而第二个上面级必须满足载人级要求并于2020年交付。
  
  ICPS将用在NASA计划中的航天飞机衍生重型运载火箭——“太空发射系统”(SLS)的早期型号上。ICPS通过商业方式进行采购,也存在潜在的可能性用于其他项目的载人系统,如NASA的商业乘员项目(CCP),该项目重点是研制低地轨道飞行系统。
  
  NASA的SLS总工程师莱尔斯(Lyles)表示,NASA仍计划研制J-2X发动机,作为任务型SLS火箭的第二级发动机。“我们在寻找一个相对小的上面级。我们初始的运载火箭低地轨道额定能力为70吨。这使我们可以再用一个相对小的上面级将‘猎户座’乘员飞行器推到低地轨道以外,并验证‘猎户座’的在轨太空能力。”莱尔斯说,“我们认为外部存在潜在可用的上面级,先不必自行研制大型级段,我们最终将改进在轨太空能力,完成全部探索任务。”一种可用的商业载人上面级有可能为深空探测提供备选的运输系统方案。(中国航天工程咨询中心 王宜晓 陈杰)

Aerojet 的构想: 依托 ISS 建造太空探索的前哨站,由 Node 4/DHS (Docking Hub System), 一个 external airlock, 一个 MPLM (Multi-Purpose Logistics Module) 居住舱, 以及一个国际舱构成,用 SEP 送到 EML, 支援 Orion 的载人任务

“For example, a 25-40 kW SEP vehicle using current technology can pre-position a human-tended habitat at L-2 to support initial Orion missions. This approach would provide an immediate deep space destination for astronauts, and L-2 is an excellent way-station to the rest of the solar system.”

猎户座PTV准备周三做跌落试验 – EFT-1猎户座进展

Orion PTV preparing for drop test on Wednesday – EFT-1 Orion progress
February 26th, 2012 by Chris Bergin  


The Orion Parachute Test Vehicle (PTV) is on track for its drop test on February 29 at the US Proving Grounds in Yuma, Arizona. The vehicle has completed processing prior to boarding the C-17 aircraft for the test of the parachute system. Elsewhere, the Exploration Flight Test (EFT-1) Orion is continuing construction in New Orleans, while the Ground Test Article (GTA) is undergoing vibration testing in Denver.
    在亚利桑那州尤马,“猎户飞船”的降落伞试验体(PTV)正在准备2月29日跌落测试。PTV在登上C-17飞机之前,已经为这次降落伞系统试验完成处理。其他方面,探索飞行试验体(EFT-1)猎户飞船将继续在新奥尔良的建设,而地面测试体(GTA)正在丹佛进行振动测试。


With the Orion Program in full swing, several Orions are enjoying their own place in the spot light – a happier situation for the vehicle that was cancelled as part of the Constellation Program cull in the FY2011 budget proposal, only to be later reinstated by President Obama for a role as a lifeboat on the International Space Station (ISS).
    作为如火如荼的猎户座计划,几个猎户座正享受着他们自己被放置在聚光灯的地方 此飞船的happier状态作为星座计划精选的一部分在2011财年预算提案被取消只在后来由奥巴马总统恢复作为国际空间站(ISS)上的救生艇的作用。


Via the approval of the 2010 Authorization Act, Orion returned to its primary role as an exploration spaceship, with a role focused on Beyond Earth Orbit (BEO) missions as far away as Mars.
      通过2010年授权法案的批准,猎户座重新担当起它作为探索飞船的主要职责,是一个以地球轨道以远(BEO)一直到火星为重点任务的职责。


   This role for Orion was always in the planning, even during the Constellation Program. The spacecraft was initially set to fly to the ISS on the Ares I launch vehicle, prior to evolving into a Block II vehicle for long duration flights into deep space.
     这个角色对于猎户座来说一直是这样,即使在“星座”计划期间。最初的计划是飞船由战深-1发射到国际空间站,早于演变成第二版本为到深空的长期持续的飞行。


December 17, 2017 is the current date for Orion’s maiden flight into deep space, launching atop of the Space Launch System (SLS) for an uncrewed mission to the Moon. An article this coming week will overview the mission, which is being called EM-1 (Exploration Mission -1).
     2017年12月17日,是目前计划的猎户座首次进入深空的日期,它被放在航天发射系统(SLS)火箭的顶端,是一个不载人到月球的任务。接下来的这一周文章将概述该任务,这(任务)被称为EM-1(探索任务-1)。




However, Orion will taste the coldness of space in early 2014, on a multi-hour mission that will see the spacecraft - known as EFT-1 – carry out a major milestone for NASA’s exploration aspirations.
   然而,猎户座将在2014年初就开始品尝太空的寒冷,在几个小时的任务中,- 已知的EFT-1 -会看到飞船开展了美国宇航局的探索愿望的重要里程碑。

Launched atop of a Delta IV-H launch vehicle, Orion will be boosted by the United Launch Alliance’s Delta Upper Stage into two orbits at a high-apogee, prior to separating and re-entering at over 20,000mph – mirroring the high energy entry profile of an Orion returning from deep space.
上盖1三角洲四​​Ĥ发射车的推出,猎户座将推动的联合发射联盟的德尔塔上阶段分为两个轨道1高的远地点,分离和超过20,000英里重新进入前 - 镜像的高能量进入个人资料猎户座深空返回。


This mission will mark the first time in decades that a NASA spacecraft – designed for human crews – will have been sent to such a distance away from the planet.
这一使命将迎来几十年来,美国航空航天局航天器 - 为人类船员设计 - 将已发送到这样的距离远离地球的第一次。


The “highest” the space shuttle orbiters ever ventured away from Earth in their 30 year career was during the Hubble Space Telescope (HST) servicing missions – usually around 350 nms in altitude – the last of which was conducted by Atlantis and her crew during STS-125. The shuttle record was held by Discovery, when she flew to 378 nms during STS-103s HST servicing mission.
“最高”的航天飞机远离地球在其30年的职业生涯中曾经大胆人造卫星是在哈勃太空望远镜(HST)服务的任务 - 通常大约在海拔350海里 - 其中最后由亚特兰蒂斯和她的船员进行过程中的STS -125。举行了由航天飞机记录发现,当她在STS-103的哈勃空间望远镜的维修任务飞行378海里。

With the mission involving numerous test milestones, the key data will come from how the heatshield/Thermal Protection System (TPS) will behave – data which will then be fed into Orion’s Critical Design Review (CDR), scheduled for around one year after EFT-1.
随着指涉及众多的测试里程碑的使馆,关键的数据将来到怎样的挡热板/热防护系统(TPS)的将行为 - 这将然后将到猎户座的关键设计审查(CDR),约一年的计划后,送入数据的EFT- 1



The Orion tasked with the EFT-1 mission is already deep into its construction milestones, with work progressing on the timeline at the Michoud Assembly Facility (MAF).

Most of the work taking place this month relates to the “barrel” – or base – of the EFT-1 Orion, as the vehicle’s construction in New Orleans presses towards the 85 percent mark.

The Michoud Assembly Facility (MAF) team completed the Gore Assembly to the Barrel pathfinder weld and the Center Panel to the Aft Structural Assembly Pathfinder Welds. The closeout weld will be the next pathfinder weld in preparation for final closeout weld operations on the EFT-1 flight unit,” noted the latest Orion status presentation (L2 – Link to Presentation).

The Launch Abort System (LAS) Adapter Cone Mandrel has been completed and delivered to MAF. LAS Mid Ring Deck is being fabricated in the Fiber Placement Machine at MAF.”

Once the construction work has been completed, the “bare” Orion will be sent to the Kennedy Space Center (KSC) for outfitting work.

Over in Denver, Lockheed Martin – the prime contractor for Orion - have their teams completing test evaluations on the Ground Test Article (GTA) Orion, following on from a long list of specialist testing on the spacecraft’s ability to cope with the pressures of launch and on-orbit operations.
---------------------
EFT-1的使命与任务的猎户座已经深入到其建设的里程碑,与工作的的Michoud大会基金(MAF)在时间轴上前进。

大部分发生这一个月的工作涉及到的“桶” - 或基地 - EFT-1的猎户座,车辆的在新奥尔良印刷机建设,向85%大关。

Michoud大会基金(MAF)团队完成的桶探路焊接和中心小组的尾部结构大会探路焊缝戈尔大会。收尾焊接将成为未来的探路者在编制EFT-1飞行部队的最后收尾的焊接操作焊接,指出:“最新的猎户座状态简报(L2 - 链接到演示文稿)。

“发射中止系统(LAS)适配器锥芯棒已经完成,并交付给农林部。阿盟中环甲板正在制作农林部。在纤维铺放机“

一旦建设工作已经完成,“裸”猎户座将被送往肯尼迪航天中心(KSC)舾装工作。

以上在丹佛,洛克希德 - 马丁 - 的猎户座的主要承包商 - 有自己的团队完成的地面测试条(GTA)的猎户座的测试评估,后,从一长串专家测试上,以配合推出的压力飞船的能力和在轨运行。

这些发育测试自去年以来已采取的地方,不仅与猎户座,但也“猎户座”堆栈元素 - 如发射中止系统及配套硬件。

----------------------
These developmental tests have been taking place since last year, not only with Orion, but also elements of the Orion stack – such as the Launch Abort System and supporting hardware.

The tests have included evaluations via what is known as the “shake and bake” test – which took place at Lockheed Martin’s Waterton facility in Denver – exposing the GTA Orion through a series of procedures which simulated the sound pressure levels that the vehicle is expected to encounter during launch, levels which can exceed 160 decibels.

This month Lockheed Martin began “multipoint random vibration” testing on the GTA Orion, again working to ensure the components of the vehicle will not come across any hidden surprises in the many environments it will be expected to survive in.

The Multipoint Random Vibration testing has begun on the Orion Crew Module Ground Test Article at the Lockheed Martin vertical test facility in Denver,” noted the Orion status update (L2). “The testing started with a low frequency (<20 Hz) and low force runs to obtain the rigid body modes.

Following the initial test, the team continued testing low force runs ranging from 70 to 100 Hz to find the isolation plate modes. The testing is planned to take 17 days but could be extended.”
测试包括通过所谓的“摇动和烘烤”测试评估 - 其中发生在洛克希德·马丁公司的沃特顿设施在丹佛的地方 - 揭露通过一系列的程序,多伦多猎户座,其中模拟的声音压力,车辆被预期到的水平期间遇到推出,可以超过160分贝的水平。

洛克希德·马丁公司本月初开始在大多伦多地区的猎户座“多点随机振动测试,再工作,以确保车辆的组件将不能在任何隐藏的惊喜,它在许多环境中来,将有望生存英寸

“多点随机振动测试已开始在”猎户座“乘员舱的地面试验条在丹佛的洛克希德·马丁公司的垂直试验设施上指出,”猎户座状态更新(L2)。 “测试开始与低频率(<20 Hz)的力低,运行获得刚体模式。

“最初的测试之后,球队继续测试低力从70到100赫兹到隔离板模式运行。测试计划需要17天,但可以延长。“


-----------------------------

However, all eyes will be on the sky over Arizona on Wednesday, as engineers prepare to conduct the latest PTV drop test for Orion’s parachute system.
然而,现在所有的目光都注视着周三亚利桑那州的天空,作为准备工程,为PTV猎户座最新型的降落伞系统实施一项跌落试验。


This Capsule Parachute Assembly System (CPAS) test on the second generation PTV will be hoping for a better outcome than the PTV (first generation) test back in 2008, which suffered a major failure, resulting in the vehicle crashing to the ground.
这个降落伞包组装系统(CPAS)测试第二代PTV将希望一个更好的结果比PTV(第一代),PTV1早在2008年遭受了重大的失败测试,(当时)导致飞船模型在地面解体。

The Capsule Parachute Assembly System (CPAS) team continued preparation activities for the first Generation II Parachute Test Vehicle (PTV) air drop, scheduled for Feb. 29,” noted the latest Orion status update (L2).

“第一代第二降落伞测试车(PTV)空投胶囊降落伞装配系统(注册会计师)团队继续为筹备活动,定于229日,”猎户指出,最新的更新状态(二级)。

Accomplishments included rigging of the CPAS Parachute Separate System (CPSS) Mid-Air Release Mechanism and recovery system; final PTV avionics tray, backshell panel and ballast installations; and completion of PTV and CPSS electromagnetic interface testing.”
“成就包括操纵降落伞的注册会计师独立的系统(CPSS)半空中的发行机制和回收系统;最后PTV的航空电子托盘,后壳面板和镇流器安装; PTV和支付及电磁接口测试完成”


The boilerplate Orion mock up vehicle and PTV system consists of eight parachutes, with another 10 parachutes required to drag the test vehicle out of the C-17 aircraft via a sledge or pallet system – which it has already been mated with during preparations - at 25,000 feet, providing the correct orientation, altitude and speed, whilst also allowing for the pallet to land safely on the ground under its own dedicated parachutes.
嘲笑猎户座的样板车和公视系统八降落伞组成,与其他10个爬犁或托盘系统通过拖动的C-17飞机的测试车辆所需的降落伞 - 它已经被交配期间的筹备工作 - 25,000脚,提供正确的方向,高度和速度,同时也允许安全降落在地面根据其自己的专用降落伞的托盘。


However, some changes – which are yet to be made public – have been made to the set-up of the system since the 2008 failure, hopefully mitigating the potential for problems during deployment.
然而,一些变化 - 这是尚未予以公开 - 已作出了系统的设置,自2008年的失败,希望减轻在部署过程中潜在的问题。

补充些细节:
1.    一艘飞船需要1300块瓦,... 这需要11个月之多才能完成...,...
   ... ...
2.  In an advancement from the shuttle days, each tile’s dimensions are sent over digitally from Orion builder Lockheed Martin and the final tile is photographed with a 3-D camera so computers can fit the pieces together virtually before they are placed together physically, Huff said. The details are far more exact than in the past.
  每块瓦要用3-D相机拍摄,然后输入计算机,... ...

  ... ...
3.  However, Orion’s tiles will be used only once because the spacecraft will splashdown in the ocean, drenching the absorbent tiles. That means that technicians will make and install all 1,300 tiles between Orion missions. Shuttles required 100 to 150 new tiles between flights, Cox said.
   虽然航天飞机的防热瓦有2万多块之多,但猎户座的防热瓦只能使用一次,因为海中溅落,防热瓦吸湿。而航天飞机每次飞行只需要150块新瓦。

The tiles are made of the same material and coating as those used on the space shuttle's belly. On Orion, however, the tiles will be placed along the sides and top of the conical spacecraft.

在轨热防护和微陨石撞击防护是在 backshell 上铺瓦片的理由。

Orion 的底部 heat shield 和 Apollo 的 材料和工艺基本相同,(把类似树脂的材料逐个注入许多蜂窝状的窟窿里)区别是更大,需要分许多片制造。

MPCV是要深空走的,很多微小流星体未必能预报得那么准确,还是加防护比较稳妥。神舟目前是近地轨道运行,危险物体&空间“天气”预报很成熟,没有必要加防热瓦死重。  发表于 2012-5-16 19:35

原计划有气囊在路上降落,后来因为要减重去掉了这个功能,任务要求海上回收。陆上降落是紧急情况下的备份。

因为返回舱的尺寸和重量,不可能空中回收。(那些能在空中回收的胶片舱其实很小,一个人就能搬动。和载人返回舱的尺寸不在一个数量级上。)
