SpaceX载人龙(飞船):把优势坚持到底
SpaceX Crewed Dragon: Pressing home theadvantage
January 10, 2013 by Chris Bergin
http://www.nasaspaceflight.com/2013/01/spacex-crewed-dragon-the-advantage/



With all three Commercial Crew partnersproviding a status update at the Kennedy Space Center (KSC) this week, SpaceXhave outlined their path towards launching a crew on their Dragon spacecraft in2015. With the advantage of already flying cargo missions on a near-human ratedDragon, SpaceX are leading the drive to return domestic crew launch capabilityto the United States.

本周,与所有三个商业载人合作伙伴一起,在KSCKSC)提供了一个状态更新,SpaceX描述了他们的龙航天器于2015年发射一个乘员组的路径。凭借已经飞行了货物任务的近似载人级别的龙飞船 的 优势, SpaceX是领先的驱动器返回国内乘员美国发射能力。

                 

SpaceXCrewed Path:
SpaceX载人路径:

… … 回顾CRS-1的故障 … …


According to SpaceX’s Commercial Crewproject manager, Garrett Reisman, some details into the root cause of thefailure will be revealed to the public in the coming weeks. However, due to theproprietary nature of SpaceX’s hardware, only SpaceX – and their customer, NASA– will ever get to see the full overview from the joint CRS-1 Post-FlightInvestigation Board report.

根据SpaceX的 商业载人项目经理,加勒特赖斯曼,将在未来几周向公众透露了(CRS-1)部分失败的根本原因细节。但是,由于专有性 SpaceX的硬件,仅SpaceX -和他们的客户,NASA - 永远不会得到联合CRS-1飞行后调查委员会报告中看到完整的概述。

     


…  …  
… … …

However, as reported byNASASpaceflight.com’s Pete Harding, it is unlikely that any NASA astronautswill get to ride on a commercial vehicle until late 2016 – as shown in ISSFlight Planning Integration Panel (FPIP) charts (available on L2) on thecurrent plan for ISS crew rotations using what are tagged as USCVs (USCommercial Vehicles).

但是,就象NASASpaceflight.com的皮特·哈丁所报告的,直到2016年底前,任何 NASA宇航员乘坐在一个商业运载器上是不可能的- 如所示的ISS飞行计划整合小组(FPIP)的图表(L2)目前的计划ISS 乘员轮换使用的标签USCVs(美国 商业运载器)。

                  

According to the FPIP chart, the first USCVwill launch in December 2016, for a docking to the Node 2 Forward port – viathe use of an ISS Docking Adapter (IDA) attached to PMA-2. A Soyuz spacecraftis also pencilled in for the same date as a back-up (all USCVs on the charthave Soyuz back-ups assigned, should the USCV not be available).
根据到FPIP图表,第一次USCV会在201612月发射,与节点2前面端口对接 -通过使用一个 ISS端口适配器(IDA)连接到PMA-2。一个联盟航天器也铅笔在相同的日期作为一个备份(所有USCVs在图表上有联盟的备份被分配,在USCV有可能无效时)。


The USCV will carry four crewmembers,meaning that once it docks to the ISS, the crew of the station will be boostedto seven – allowing significant extra research activities to be performed.However, one of the crewmembers on theUSCV will be Russian – just as one American crewmember will continue to berotated on the Soyuz.
USCV将搭载4名机组人员,这意味着一旦它停靠在ISS,该站的乘员组将提高到7个人 - 允许进行显著的额外的研究活动 但是,USCV的乘员之一将是俄罗斯人 - 正如一个美国乘员将继续轮流(乘坐)联盟。
                 
This is done in order to ensure that a UScrewmember is always present on the ISS, even when no USCV is docked to thestation. It is not known at this point whether the seat on the USCV will beprovided to Russia inexchange for a USseat on the Soyuz.
这样做是为了确保一个美国组员始终出现在ISS上,即使没有USCV停靠到该站。在这一点上不知道USCV的座位是否会被提供给俄罗斯,以作为一个美国座位换取一个联盟上的座位。
              


Per the commercial crew update briefing,only SpaceX have said they will be able to conduct crew launches as early as2015 – meaning the crew will be selected in-house, as opposed to being assignedby NASA.

按照 商业载人更新简报,仅SpaceX表示,他们将可以在2015年早期进行乘员发射意味着乘组将在内部选择,而相对的被指派的NASA

                    

…  … …


“We laid out aplan that gets us to flying the first test flight in the middle of 2015,followed by flying a crew to the ISS by the end of 2015,” noted Mr Reisman.“That would be done with a test pilot crew.
我们制定了一个计划,可以让我们在2015年中飞行第一次测试跟着的是在 2015年底飞行机组人员到ISS赖斯曼先生指出:。这将是一名试飞员的乘员
                             

Click here for recent Dragon Articles:http://www.nasaspaceflight.com/tag/dragon/

“(However,)because this would be done prior to final (NASA) certification, we are notlegally allowed to use NASA astronauts to be part of that test pilot crew – soit will be SpaceX test pilots for that crew. We’re not selling tickets, sodon’t call our toll-free number.”
(无论如何),因为这将 最后(NASA)认证前进行,我们不能合法使用NASA宇航员,成为试飞员乘员的一部分, - 所以这将是SpaceX的测试飞行员作为乘员。我们不是卖门票,所以不要拨打我们的免费电话号码。


Mr Reisman, a two-time Shuttle astronaut,intimated he is not interested in becoming one of the test crew.
赖斯曼先生是两次航天飞机的宇航员,暗示他没有兴趣成为一个测试人员。
                             

…  … …


Dragon sports a series of eight liquidSuperDraco engines, built into the side walls of the Dragon spacecraft, capableof producing up to 120,000 pounds of axial thrust to drive the Dragon away fromits failing launch vehicle.
龙(排列了)一系列8 SuperDraco的液体引擎,建在龙航天器的侧壁内,能够产生高达12万英镑的轴向推力,推动‘龙’远离其失败的运载火箭。


Advantages of the SuperDraco liquidthruster – when compared to the traditional use of solid propellent – includeshow the engine can be put through a series of throttling ranges, in turnallowing for redundancy,
withSpaceX claiming they could lose one of the eight abort engines and stillrecover the vehicle and crew successfully. The engines can also be restartedmultiple times.
SuperDraco液体推进器的优点 - 相比使用传统的固体推进剂, - 包括发动机如何可以通过一系列的节流范围,从而允许冗余,SpaceX声称他们在可能会失去8个中断发动机之一(的情况下)同时成功地回收运载器和乘员。该发动机还可以多次重启。
                  
Anotheradvantage is the fact it’s not a tower system, which normally requires jettisonshortly after first stage flight. Any failure of this key sequence of ascentwould end the mission, given the flight profile wouldn’t be designed forcarrying the LAS along for the ride.
另一个优点是它其实不是一个塔(型)系统,那通常在第一级飞行后不久需要抛弃。这个键序列上升的任何故障都将结束任务,的飞行剖面被设计为携带LAS凑凑热闹。
                        

Because the system is integrated into theDragon itself – as opposed to departing the spacecraft during jettison – thespacecraft can technically abort within much longer periods than the towerversion. With Dragon returning with the engines on board, they can also bereused on future launches.

由于该系统被集成到龙本身 - 而相对的背离的航天器在抛弃 -  该航天器比塔型版本在技术上可以在更长的时间段(执行)中止。该引擎随着龙在船上(一起)返回,未来发射的,他们也可以重复使用。

                                    

There is also a large amount of commonalitybetween the 18 maneuvering engines built into Dragon and the SuperDraco LASengines – bar the fact the SuperDraco engines would burn through propellant 200times faster.

建造在龙内部的18个机动发动机  和 SuperDraco LAS引擎之间, 还有大量的通用性(空间?)  - 阻止事实的SuperDraco引擎通过推进剂燃烧速度快200倍。

                        
                            
The additional applications of thesethrusters, when unused during a nominal mission – is the ability for them toenable a return to a landing strip on land. This is a key goal as part of thefully reusable launch system SpaceX are working on, along with the potentialuse for landing on exploration missions, such as the surface of Mars.
这些推进器的附加应用, 在一个正常任务期间不使用 - 是他们的能力给力回归到着陆地带的土地。这是一个完全可重复使用的部分主要目标发射系统SpaceX工作,随着登陆探索任务小号的潜在用途,如在火星表面。


…   … …
During the year, reviews will take placeinto the second abort test, which will result in a Falcon 9 with Dragonlaunching as per usual, prior to aborting at the “worst possible time” duringascent. That “In Flight Abort Test” is expected in April of 2014.

年内,评论会发生的第二中止测试,这将导致按通常的猎鹰9号和龙推出,在中止之前  “最坏的时刻在上升过程中。飞行中止测试”  预计在20144月。

SpaceX Commercial Crew project managerGarrett Reisman says his company's plan to conduct a pad abort test in Decemberremains on track, paving the way for a test flight to the space station with anon-NASA crew in a version of the Dragon spacecraft in 2015. “What we think weneed to complete launch assurance is just over two years, so we could do a testwith people on board around mid-2015. That is what we proposed under CCiCAP andit is the trajectory we are on today but,” depending on funding, that may nothold,” he warns.
SpaceX 商业载人项目经理加勒特赖斯曼说,他的公司计划在12月进行的发射台中止测试仍在计划进度之内,为在2015年一个非NASA的版本龙乘员 航天器 到空间站的测试飞行铺平道路。“我们认为的是,我们需要完成的发射担保仅仅超过两年,所以我们可以在2015年中期左右做一个载人飞船测试。这就是我们在CCiCAP下的打算,并且这(也)是我们今天所处的(轨迹位置),但“根据投资,这有可能控制不住“他警告说。

The company delivered a detailed pad aborttest plan to NASA in March, and in May completed its human certification planreview with delivery of overall certification and master verification plans.The preliminary design of the automatic-approach-and-docking system as well asthe entry, descent and landing system is subject to an on-orbit and entrypreliminary design review in July. Following a Dragon parachute test in August,the detailed inflight abort test review is slated for September, with theover-arching safety review covering hazard analysis, safety assessment andfailure modes, due in October.

Following a flight review of the upgradedFalcon 9 standard for human missions in mid-November, SpaceX plans to conduct apad abort test a month later. “The primary structure for the pad abort isalready fabricated and almost complete. This the next really exciting milestoneand the first abort test as part of commercial crew program. We are going tostick Dragon on top of a Falcon 9 and take it to the transonic regime. We willlight up the launch abort system and fly away safely from the Falcon 9. Thiswill demonstrate total thrust (as opposed to total impulse),” adds Reisman.“Then we move on to the human certification review.” The qualification effortof the Dragon primary structure is due to be completed in mid-January, with theintegrated CDR for the entire vehicle now set for March 2014 and an inflightabort test the following month.

SpaceX正式 完成第五个和第六个CciCap评审里程碑:
5 (原计划2013-03 Test Reviews For Pad Abort(发射台中止测试评审)
6 (原计划 2013-05 Human Certification Plan Review(载人认证计划评审)
                 
These were the fifth and sixth milestones for SpaceX, a partner in NASA’s Commercial Crew Program (CCP). The company is on track to complete all 14 of its CCiCap milestones by mid-2014.
In a human certification plan review May 7, SpaceX outlined all the steps the company plans to take to certify its system for crewed missions, including testing, demonstrations, analyses, inspections, verifications and training events. This was a key milestone to ensure SpaceX’s integrated Falcon 9 rocket and Dragon capsule will be safe to carry humans to and from low-Earth orbit beginning in the middle of this decade.
At its pad abort test review, SpaceX presented plans for a pad abort test, currently targeted for later this year or early next year from Cape Canaveral Air Force Station’s Space Launch Complex 40 in Florida. The review successfully demonstrated the adequacy of the test plan objectives and the pad abort scenario.

NASA商业载人合作伙伴SpaceX完成轨道(维持)和进入评审
NASA Commercial Crew Partner SpaceXCompletes Orbit and Entry Review
Aug. 15, 2013   RELEASE 13-255
            
NASA Commercial Crew Program (CCP) partnerSpace Exploration Technologies (SpaceX) recently reviewed the systems criticalto sustaining crews in orbit and returning them safely to Earth aboard thecompany's Dragon spacecraft.
NASA商业载人计划(CCP)的合作伙伴太空探索技术公司( SpaceX)最近审查了该系统,以关键地维持乘员的长时间在轨,并且使他们乘坐该公司的龙飞船安全地返回地球。
                              
SpaceX is one of three commercial spacecompanies working under NASA's Commercial Crew Integrated Capability (CCiCap)initiative to develop spaceflight capabilities that eventually could providelaunch services to transport NASA astronauts to the International Space Stationfrom U.S. soil.
SpaceX是三个商业太空公司之一,(他们)工作在NASA商业载人的集成能力(CCiCap)倡议发展的航天能力,最终能够提供发射服务, 从美国本土运输NASA宇航员到ISS。
               
During the preliminary design review atSpaceX headquarters in Hawthorne, Calif., company engineerspresented NASA representatives and aerospace industry experts detailed analysesof Dragon systems critical to keeping crews safe in orbit and during re-entryoperations. From basic life support functions, including pressurizing Dragonwith breathable air, to stocking the capsule with enough food and water for asmany as seven crew members, the spacecraft must be designed to protect humansin the harsh conditions of space. Company designers and NASA engineersdissected the plans carefully to make sure no details were overlooked.
在 加州霍桑的SpaceX总部的初步设计评审期间,公司的工程师们向NASA的代表和航空航天业专家做了介绍,(这些介绍)对龙系统乘员的关键在轨安全维持以及再入操作做了详细分析。从基本的生命支持功能(包括用可呼吸的空气加压龙飞船),到 维持(放养)太空舱 多达七名机组人员 所需的足够的食物和水 ,该航天器必须设计为太空苛刻的条件下去保护人员。公司的设计师和NASA工程师仔细解剖了该计划,以确保没有忽视任何细节。
                                
"NASA has learned a lot about keepingour astronaut crews safe throughout a mission, and we don't want those lessonsto be forgotten," said Ed Mango, NASA's CCP manager. "So, we're sharinga lot of what we already know, and the company is adding its own innovations tosuit its needs and meet its challenges."
“NASA已经学到了很多东西,在整个任务中保持我们的宇航员乘员的安全,我们不希望这些经验教训被遗忘,”ED Mango说,他是NASA的CCP经理。“所以,我们分享了很多我们已经知道(的东西),并且该公司也加入了自己的创新,以满足其需求,并应对其挑战。“
                       
The review detailed equipment and softwareaboard Dragon that would help guide crews to the International Space Stationfor rendezvous and docking operations. This included discussion on SpaceX’splanning for software code which, in this modern era of spaceship design, justas critical as the hardware design. The company also described how thespacecraft will be operated both by its onboard crew and by ground controllers.
该评审详述了龙飞船上的设备和软件,这将有助于引导乘员 交会对接到ISS的操作。这包括讨论 SpaceX规划的软件代码,在这个飞船设计现代化的时代,其和硬件设计是一样重要的。该公司还介绍了 其飞船上的乘员和地面控制人员 如何操作该航天器
                     
While SpaceX works to further develop itscrewed Dragon spacecraft, it also is preparing for the upcoming launch of thethird of at least 12 cargo missions to the space station with a remotelycontrolled Dragon under NASA's Commercial Resupply Services contract.
当SpaceX努力以进一步发展其载人龙航天器时,它也正准备为即将到来的发射至少12个货物任务的第三 空间站远程控制下龙 NASA的商业补给服务合同。
     
"SpaceX’s Dragon spacecraft was designedfrom the outset to accommodate the upgrades necessary to safely carry people,so we’re excited to have reached the halfway point in our agreement with NASAto design those features,” said Gwynne Shotwell, SpaceX president and chiefoperating officer. “As we leverage our experience successfully delivering cargoboth to the International Space Station and back to Earth, SpaceX remainscommitted to providing the safest manned flights ever conducted."
“ SpaceX龙航天器的设计从一开始就适应(容纳了)必要的安全地进行载人的升级,所以我们很高兴在我们的协议中NASA一起设计这些功能,(并且)已经达到了中间点,” 奎恩肖特韦尔说,他是 SpaceX总裁兼首席营运官。“当我们成功地利用我们的经验,同时向运送货物 和背面ISS地球, SpaceX仍然致力于为客户提供最安全的载人飞行进行过。“
              
In December, the company completedpreliminary design reviews covering the ground systems and ascent, which arethe first two phases of flight. Completion of the orbit and entry review clearsthe way for SpaceX to proceed with detailed designs for its integrated spacetransportation system, comprised of its Dragon spacecraft, Falcon 9 rocket andsupporting ground systems.

完成飞行中中止测试评审里程碑(8/15),原定于今年第的发射台中止测试已经推迟到明年春天。
   

WASHINGTON (NASA PR) – In preparation for a summer 2014 test, NASA partner Space Exploration Technologies (SpaceX) recently laid out its plan to demonstrate the Dragon spacecraft’s ability to carry astronauts to safety in the event of an in-flight emergency.

This review of the in-flight abort test plan provided an assessment of the Dragon’s SuperDraco engines, the software that would issue the abort command, and the interface between the Dragon spacecraft and the Falcon 9 rocket on which the spacecraft will be launched.

“It’s critical to have a launch abort system in which NASA and SpaceX can have confidence,” said Phil McAlister, director of Commercial Spaceflight Development at NASA Headquarters in Washington. “When you put humans aboard, safety and reliability are paramount and this review and the upcoming tests will help prove their space transportation system is on the right track.”

Experts from NASA and the Federal Aviation Administration attended the review of the in-flight abort test plan Sept. 17 at SpaceX headquarters in Hawthorne, Calif. Attendees also had the opportunity to view the Dragon test spacecraft, which is being manufactured for an upcoming pad abort test and, potentially, the in-flight abort test.

“With NASA’s support, SpaceX continues to implement the necessary modifications to equip Dragon to fly crew,” said Garrett Reisman, commercial crew project manager at SpaceX. “SpaceX and NASA believe in rigorous flight testing and we are looking forward to putting our SuperDraco launch abort system through these critical tests, starting with the pad abort test in the spring and followed by the in-flight abort test in the summer.”

The in-flight abort test will take place along Florida’s space coast. During the test, a Dragon spacecraft will launch on a standard Falcon 9 rocket and an abort command will be issued approximately 73 seconds into the flight. At that point, the spacecraft will be flying through the area of maximum dynamic pressure, or Max Q, where the combination of air pressure and speed will cause maximal strain on the spacecraft.

Dragon will be outfitted with about 270 special sensors to measure a wide variety of stresses and acceleration effects on the spacecraft. An instrumented mannequin, similar to a crash test dummy, also will be inside. The spacecraft’s parachutes will deploy for a splashdown in the Atlantic, where a ship will be pre-positioned for simulated rescue operations. The test spacecraft will be returned to Port Canaveral by barge so data can be retrieved and incorporated into the system’s design.

SpaceX建造用于发射中止测试的龙飞船
SpaceX Builds Dragon for Launch Abort Test

SpaceX is deep into the production of the Dragon spacecraft that will be used to demonstrate the craft’s launch abort abilities during a test launch next year. The ability of a spacecraft to escape from an emergency situation at the launch pad or during ascent into space is a major priority for the next generation of American spacecraft now under development in partnership with NASA’s Commercial Crew Program. The Dragon spacecraft will use powerful, side-mounted Draco thrusters to lift the spacecraft away from its booster soon after liftoff during the test. No one will be inside the spacecraft for the launch, but the mission parameters will be set up as though there were, with extensive instrumentation and parachutes aboard to safely recover the Dragon.
SpaceX已经深入到龙航天器的生产,(该龙飞船)明年测试期间,将用于演示航天器发射中止的能力,在 与NASA 为下一代美国航天器开发 的 商业载人计划合作 下,一个航天器在紧急情况下逃离发射工位或在上升过程中进入空间的能力 是重点优先(考虑)的。在测试过程中,该龙航天器将使用强大的、侧装的Draco推进器,在升空后不久,使该航天器解除并远离其助推器。这次发射没有人在航天器的里面,但任务参数将被设置,就像仿佛有人一样,其上广泛的仪器仪表和降落伞用于安全地回收该龙飞船。

完成安全评审里程碑
1. 这不是安全讨论的结束,而是开始。
  2. Pad 逃逸测试在2014年第二季度,飞行中测试在第三季度。
  3.用于逃逸测试的飞船已经在制造中,火箭的制造预期马上开始。
  4.这是CciCap中15个里程碑的第9个。
         
   
NASA Commercial Crew Partner SpaceX Achieves Milestone in Safety Review
Nov. 15, 2013   RELEASE 13-337
http://www.nasa.gov/press/2013/november/nasa-commercial-crew-partner-spacex-achieves-milestone-in-safety-review/#.UobODrKcEns

            
Engineers and safety specialists from NASA and Space Exploration Technologies (SpaceX) met in late October to review the safety of the Dragon spacecraft and Falcon 9 rocket being developed to launch humans into low-Earth orbit later this decade.
The detailed overview of safety practices the company is implementing was a major milestone for SpaceX under a funded Space Act Agreement with NASA's Commercial Crew Program (CCP).
………..
A team of NASA engineers went to SpaceX headquarters for two days of detailed presentations and question-and-answer sessions that reviewed the company's safety practices.
"The milestone is not the end of the safety discussion, it's really the beginning," said Jon Cowart, deputy manager of the NASA Partnership Integration Team for CCP. "Because we've been doing this for so long, we all have a pretty good idea of what works and what doesn't and how safety processes can be strengthened to increase our confidence in the system."
………..
…….
………..
…………..
The first test will simulate an abort from the pad prior to launch in the second quarter of 2014. The second test, targeted for the third quarter of 2014, calls for the spacecraft to separate from a Falcon 9 booster in flight and parachute safely into the Atlantic Ocean. The company is building the spacecraft for the flight tests and manufacturing of the rocket is expected to begin shortly.
This safety review was the ninth milestone for SpaceX under CCiCap. The company is on track to complete all 15 of its CCiCap milestones by the third quarter of 2014. All of NASA's industry partners, including SpaceX, continue to meet their established milestones in developing commercial crew transportation capabilities.

     NASA从2017年开始可能逐渐弃用俄联邦航天局“联盟号”飞船为其宇航员提供搭载服务。据NASA主任查尔斯•博尔登介绍,NASA打算与私人公司签订合同,建造可以提供宇航员到国际空间站的新一代火箭和飞船。据推测, 两家公司SpaceX公司和轨道科学公司将与NASA合作的原则,就是公共和私营部门的伙伴关系。
      SpaceX公司总裁格温•肖特韦尔建议,这样的伙伴关系将不仅使美国返回到空间运输系统业务,而且安全和符合成本效益,也给美国人新的就业机会。她还呼吁美国政府从预算中拨出更多的资金来资助NASA的计划。肖特韦尔说,这项 “非常重要的工作” 一年仅仅为$ 17亿美元,相比之下,美国人每年花在啤酒上的消费至少100亿美元。
      据专家介绍,近年来,美国向俄罗斯支付一次“联盟号”的搭载费用为6500万美元。

    不是完全弃用联盟,根据现在打算,2017年后,一少部分宇航员要互相搭乘对方的飞船。这样做的目的,可能是为了保持某种稳妥性吧。

那些应该是绳索的挂点,这是降落伞测试用test artical,没有推进器  发表于 2013-12-20 11:02
从图上看,侧面靠上部分有几处对称的突起,喷口向下。或许就是所谓的Push LAS了,可这尺寸比想象的来得小不少,原以为会鼓起一大块的。。。  发表于 2013-12-20 10:28
