The historical development of space shuttle, was it can be said that long-standing.
航天飞机的发展历史,可以说是由来已久了。Completes the Apollo programafterthe 60'sUS, will then research and develop the strength the focusto place„may the multilaunchingandmaintenancebe simple”on the space shuttle. Butinthisaerospacecompetition, Soviet Unionnaturally was also follows, causedBlizzard, the birdnumberand other space shuttles, andyieldedcertainresult.
从六十年代美国完成阿波罗计划之后,便将研发力量的重心放在了“可多次发射、维护简单”的航天飞机上。而这场航天竞赛中,苏联自然也是紧随其后,先后弄出了暴风雪号、小鸟号等三架航天飞机,并且取得了一定成果。Undersuchbackground, Chinais naturally unwilling to fall behind, the correspondingplanis also following close onappearing.
在这样的背景下,华国自然不甘落后,相应的计划也紧跟着出台。For exampleinitialcode name863-204projects, isso-called„earth orbit transportation system”, in the initial period of project bidding, domesticspace expertfor„space shuttle” the mattereruptsoneto waste timefor a long timeargument. Evensupported the sound of space shuttleonceto get the winning side.
比如当初的代号863-204的项目,也就是所谓的“天地往返运输系统”,在项目招标的初期,国内的航天专家就为“航天飞机”的事情爆发过一场旷日许久的争论。甚至于支持航天飞机的声音曾经一度占据了上风。Howeverwhenallseeminglysettle down, thisreported that was delivered toat that timealreadyVenerablemoney who steps down to the second linethere.
然而就在一切看似尘埃落定的时候,这份报告被送到了当时已经退居二线的钱老先生那里。
After Venerablemoneyhas read the report, only above postilninecharacters, butalsothisshortninecharacters, completelychangedalmostalready the space shuttletechnological line that is settled, changed the futurelook of Chinaspace undertaking.
钱老先生看过了报告之后,只在上面批注了九个字,而也正是这短短的九个字,彻底改变了几乎已经板上钉钉的航天飞机技术路线,也改变了华国航天事业的未来面貌。„Shouldalsoreport the center the spaceshipcase.”
“应将飞船案也报中央。”Nowlooks back, was makingsuchchoicesat that time, without doubtis correct.
现在回过头去看,在当时做出这样的取舍,无疑是正确的。
The space shuttledoes not look likelike thatattractively, the super power that even iftwo that in the surfaceseems like„the strength of whole nation”competes, is still hardto supporthumanto the freeround-tripaerospacedream.
航天飞机并非像表面上看起来的那般光鲜,就算是两个“举国之力”较劲的超级大国,也难以支撑人类对自由往返空天的梦想。Take US for instance, design service life20years of Columbia/100launches, butUScomplete5were operationalspace shuttleto addto surpassreluctantly100times, andeach time the cost of launchandmaintenance was also far higher thanat the beginning of the designestimate.
以美国为例,哥伦比亚号的设计寿命20年/100次发射,但美国全部五架投入使用的航天飞机发射次数加起来才勉强超过了一百次,并且每次发射与维护的成本也远高于设计之初的预估值。ButSoviet Unionwas more miserable, threespace shuttleshave launchedrespectivelyonetime, in the 90's, isto fly unable to fly, a testerwas also boughtto place the museumbyGermany.
而苏联就更惨了,三架航天飞机分别发射过一次,九十年代之后更是飞都飞不起来,其中一台测试机还被德国买去放在了博物馆。Tosses aboutwithit, might as welluses the rocketsimply, howstudiesto receivewell the bumper missile, costnot necessarilycompared withmaturespace shuttletechnologyexpensivemany.
与其这么折腾,还不如干脆用火箭,好好研究研究怎么把二级火箭收回来,成本未必就比成熟的航天飞机技术昂贵多少。However, timealwaysinchange.
然而,时代总是在变化的。Ifviews the issuewith the vision of development, anyissuecanfindto solve the problem the mentality.
如果用发展的眼光来看待问题,任何问题都是可以找到解决问题的思路的。Space shuttleassemblycenter.
航天飞机装配中心。Standsinside of industry robot, bringingLu Zhou of glovechild to pick up a metalcylinder of mineral springthermosizefrom the plasticbasket, withthought overin the hand, thenapproached the port of thatmetalcylinder, looked at carefullyalongthatbright and cleanmetal surfacecarefully.
站在工业机器人的旁边,带着手套的陆舟从塑胶筐子里捡起了一只矿泉水瓶大小的金属圆筒,拿在手中掂量了下,然后凑近了那金属圆筒的端口,沿着那光洁的金属表面仔细地端详了起来。„Howto feelin a big wayentiretwo?”
“怎么感觉大了整整两圈?”OnnearbyNC machineterminalscreen, shootsonestring of air bubbles.
旁边数控机床终端屏幕上,弹出来一串气泡。Xiao Ai: 【Is unfair to the master! Thisis the minimumsize that Xiao Aicanachieve...... qaq】小艾:【对不起主人!这已经是小艾能做到的最小尺寸了……qaq】Lu Zhou: „This, Ihave not blamedyou...... youto dowas very good.”陆舟:“别这样,我又没有怪你……你已经做的很不错了。”Xiao Ai: 【Real? 0.0】小艾:【真的吗?0.0】„......”
“……嗯”Xiao Ai: 【Happy! Phi( ≧ ≦ *)?】小艾:【开心!φ(≧≦*)?】Lu Zhou: „......”陆舟:“……”At this momentgraspsinhishand, is inwreckage 3rd the enlargementversion of Hall thruster, is the limit that thisNC machinecanprocess.
此刻握在他手上的,便是残骸三号上霍尔推进器的放大版,也是这台数控机床所能加工到的极限。Lu Zhouhasto tryto letXiao Ai, indid not sacrifice the performanceunder the condition, is smaller, howeverstartsfrom the presentvolume that thisgadgetdoes, the section largest diameterreduces1 mmevery time, not only the overallprocessingdifficultywill show the growth of Geometrytype, the stability of advancementadvancementunitseriouslywill also be affected.陆舟不是没有试着让小艾在不牺牲性能的条件下,将这玩意儿做的更小一些,然而从现在的体积开始,截面最大直径每缩小1mm,不但整体加工难度都会呈几何式的增长,推进推进单元的稳定性也会受到严重影响。However, even if hardto return to original statecompletelyin the wreckage 3rd technology, thisreplica is still quiteoxBai.
不过,即便难以将残骸三号上的技术完全还原出来,这个仿制品也是相当牛掰的。1.32 meters in diameterenginemouthcanintegrate200Hallto advance the unitprobably, through conducts the turbo-chargedrectificationto the ionizationindoorplasma statexenon, cansprayto accelerate to1/1000speed of lightbackward the plasma plume, thushas the maximum200 knthrust force.
直径1.32米的引擎口大概能集成200支霍尔推进单元,通过对电离室内的等离子态氙气进行增压整流,能够向后喷射出加速到千分之一光速的等离子体羽流,从而产生最大200kn的推力。
The thrust force200 kn , 5stageengine of singlestageengineaddsis1000 kn.
单台引擎的推力200kn,5台引擎加起来就是1000kn。Even if conducts to calculateby50tonsfullload, can still obtainabout the 1 gaccelerationunder the gravity ringboundary. Althoughinaccelerationrapidinchemical rocket, but the advantageinspecific impulseactuallymakesitnot needto carry very heavyworking substance, thencansend to the low earth orbit.
即便是以50吨满荷载进行来算,在重力环境之下也能够获得将近1g的加速度。虽然在加速度上迅速于化学火箭,但在比冲上的优势却使得它无需携带很重的工质,便可以将自己送上近地轨道。Now the onlytroubleis, a 100 mwfusionbattery is only probably satisfiedenough the demand of 1xHall thruster.
现在唯一的麻烦就是,一台100mw的聚变电池大概只够满足一台x型霍尔推进器的需求。Ifwantsto satisfy the energy consumption of thistype of Hall thruster, hemustgo a step further power of promotionfusionbatteryto be good.
如果想要满足这种霍尔推进器的能耗,他必须进一步升级聚变电池的功率才行。„It seems likemustresult in the powerline of improvement of fusionbatteryto500 mwabove...... bestis1000 mw,”stares atHall in handto advance the unit, Lu Zhouwas pondering overis saying, „alsohad the PMSalso the improvement...... saying that had the meansto be able the ionization chambers of fiveenginesto integratetogether? Makes a large sizeandintegrationto advance the unit the Hall thrusterto come outsimply.”
“看来必须得将聚变电池的功率提升到500mw以上才行……最好是1000mw,”凝视着手中的霍尔推进单元,陆舟思忖着说着,“还有电源管理系统也得改进……说起来有没有办法能将五台引擎的电离室集成在一起?或者干脆弄个更大号、集成更多推进单元的霍尔推进器出来。”Advanced the unitto returnin the plastic containerto fixHall, Lu Zhouturned aroundto leave the assemblycenterworkshop, came to the office in nearbymain building, found the Starry Sky Technologyspace shuttleassemblycenterCTOto await the honor of your presence.
将霍尔推进单元放回到了塑胶容器内固定好,陆舟转身离开了装配中心的厂房,来到了旁边主楼的一间办公室里,找到了星空科技航天飞机装配中心的技术总监候光。Speaking ofthisawaiting the honor of your presence, is an expert.
说到这位候光,也是一位牛人。Ashad participated in the seniorprofessors of 863-204projects, althoughhefollowed the teacherto be engaged in the design of space shuttleasinternat that time, butgained inquiterichresearchexperienceinthis/shoulddomainas before. Afterwardheld the post ofprofessorinCapitalNavigationUniversity, was engaged in the research of space industry.
作为曾经参与过863-204项目的老教授,虽然他当时是以实习生的身份跟随导师从事航天飞机的设计,但依旧在该领域积累了相当丰富的研究经验。后来在京航大学担任教授一职,从事航天领域的研究。Properly speaking, suchexpert is very difficultto dig, howeverinknowing the manager in enterpriseisLu Zhou, after Lu Zhouplansto produce the space shuttle, hehas not even spoken in detail the treatment, thenreceivedStarry Sky Technologyofferwithout delay, next daythenrushed toJinlingfar away.
按理来说,这样的牛人是很难挖到的,然而在得知企业的老总是陆舟,陆舟打算造航天飞机之后,他甚至连待遇都没详谈,便二话不说地接下了星空科技的offer,次日便大老远地赶到了金陵。SincehebecameCTOthat day, by the presentalreadyover the past month.
从他就任技术总监一职的那天算起,到现在已经过去一个多月的时间了。Regardinghiswork, Lu Zhou has been very satisfied.
对于他的工作,陆舟一直都很满意。Howto designthisspace shuttlespecifically, after all is nothisspecialty, thisspecializedmatter, gives the specializedhuman affairsto processis quite good.
具体如何设计这个航天飞机,毕竟不是他的专长,这种专业的事情,还是交给专业人事去处理比较好。„...... The blueprint of space shuttleIhave carefully studied, considering that the energizingpartalsohas the size of electric propulsion system, over 40%placesmustredesign.”
“……航天飞机的设计图我已经仔细研究过了,考虑到供能部件还有电推进系统的尺寸,40%以上的地方都得重新设计。”Lu Zhou: „Over 40%arewhatconcepts.”陆舟:“40%以上是个什么概念。”Awaited the honor of your presenceto thinka while, gave a more explicitview.
候光想了一会儿,给出了个更明确的说法。„From the wingpositionbackward, mustredesignprobablycompletely.”
“大概从机翼位置向后,全部得重新设计。”Lu Zhounods.陆舟点了点头。„Space shuttle you are an expert, according tocomeson the line that yousaid. Moreover, according toyourexperience, Ihopes that youandIappraisesimply, how muchmoney does the entireprojectneedprobably?”
“航天飞机这块你是行家,按照你说的来就行了。另外,根据你的经验,我希望你和我简单的评估一下,整个项目大概需要多少钱?”Awaited the honor of your presenceto hesitatea while, said.
候光沉吟了一会儿,开口说道。„Conservative estimate1 billionUS dollars...... naturally, before the newdesign proposalcomes out, no onecan reach an agreementcanspendmanyspecifically.”
“保守估计得10亿美元……当然,在新的设计方案出来之前,谁也说不好具体会花多少。”1 billionUS dollars......
10亿美元……At the cost of space shuttle, thispriceis not expensive, after allColumbiaaltogetherspent the Americanfrom the research and developmentto the construction2.5 billion, moreoverisdozensyears ago 2.5 billion. Canmakewith1 billionUS dollars, to a great extentalsooccupiedmostdesignsalreadyinthe 90'sbefore the small advantage that the millenniumcompletes, as well asthisassemblycentercanprocessmostcomponents, onlyneedsto supply the basicraw materialthen.
以航天飞机的成本来讲,这个价格不算贵,毕竟哥伦比亚号从研发到建造总共花了美国人25亿,而且还是几十年前的25亿。能用10亿美元就造出来,很大程度上也是占了大部分的设计已经在九十年代至千禧年之前完成的便宜,以及这座装配中心能够加工绝大多数的零件,只需要供应基本的原材料即可。However, althoughtoburnmoneywas ready......
然而,虽说是已经为烧钱做好了准备……These1 billionUS dollarscosts, a littleexcessedhisbudget.
这10亿美元的成本,着实有点超出了他的预算。Thinks ofhere, suddenlyLu Zhoualsoworriesfor the matter of money.
想到这里,一时间陆舟也不禁为钱的事情犯了愁。Cansell an East Asianelectric power the stock?
要卖一点东亚电力的股票吗?Althoughhas not gone on the market, the words that butsellsdefinitelydo not worryto sell, after allwill beindividual can seethisfusionindustry magnatein the futurepotential. HowevernowFu Xidui of Daya Baybegins construction, the Southeast Asiaelectrical networkprojectjustwalkedoneissue, at this timewas eliminatedreallyowes.
虽然没有上市,但卖的话肯定还是不愁卖的,毕竟是个人都能看得见这家聚变行业巨头在未来的潜力。然而现在大亚湾的伏羲堆才开始动工,东南亚电网项目才刚刚走完一期,这时候出局实在是太亏了。Orlends moneyto the bank?
要不向银行借钱?Howeverthisdoes the aerospace, thisinvestment cycleis long, cannot see the obviousprofitexpectedproject, wherehas that easyloan.
不过这可是搞航天啊,这种投资周期长,看不到明显盈利预期的项目,哪有那么容易贷款。WhenLu Zhouis hesitating, the entrancebroadcast the sound of knocking on a doorsuddenly.
就在陆舟犹豫着的时候,门口突然传来了敲门的声音。Took back the train of thought of radiation, Lu Zhoulookedto the entrance, opened the mouthto say.
收回了发散的思绪,陆舟看向了门口,开口道。„Come.”
“请进。”
The gateshoves open, sees only the assemblycenterplant managerofficesecretary, appearedin the entrance.
门推开,只见装配中心厂长办公室秘书,出现在了门口。
It seems likehas not thought ofLu Zhouhere, thatsecretarysaw after Lu Zhou, gawkedslightly, butwas quickonherfacethento reappear the pleasantly surprisedexpression.
似乎是没想到陆舟在这里,那位秘书看到陆舟之后微微愣了下,不过很快她的脸上便浮现了惊喜的表情。„Professorland!”
“陆教授!”Lu Zhou: „Whatmatter?”陆舟:“什么事?”With the excitingtone, shecontinuesto say.
用激动的语气,她继续说道。„A while agowetofunds of space agencythat sideapplication, alreadybatch!”
“前段时间我们向航天局那边申请的经费,已经批下来了!”
