hey everyone in this video I'm going to be talking about the sound suppression water system used at the mobile launcher platform for the space shuttles for their launches.
嘿，在这个视频中的每个人我将谈论移动发射器平台上用 于发射的航天飞机的声音抑制水系统。

so the basic overall point of having the sampler suppression system is to alleviate the stresses on the space shuttle when,
因此，采样器抑制系统的基本要点是减轻航天飞机上的压 力，
when it's rockets,
当它是火箭时，
when the solid rocket boosters firing and when the spatial main engines are firing,
当固体火箭助推器射击和空间主发动机射击时，
the acoustical energy can reflect off of the bottom of the launcher and then and excite some of the the resonant frequencies in the space shuttle which could shake it pretty much apart.
声能可以从发射器的底部反射，然后激发航天飞机中的一 些共振频率，这可能使它相隔很远。
so this assistance actually there's actually a lot more going on,
所以这个援助实际上还有很多事情要发生，
and I had initially thought when I started looking at it,
当我开始看它的时候，我最初想过，
but pretty much.
但差不多。
I had these four sections here and I'll go through each one of them,
我在这里有这四个部分，我将通过它们中的每一个，
so the first one I look at is this one here,
所以我看到的第一个就是这个，
which is the side view,
这是侧视图，
so you can see here this piece right here is the mobile launcher platform up here you have the solid rocket booster and you have the space shuttle here with it's.
所以你可以看到这里的这一块是移动发射器平台，你有固 体火箭助推器，你有这里的航天飞机。
there should be three,
应该有三个，
but this is just a side view.
但这只是一个侧面观点。
so there's a spatial domain engines for the ssmes and then the solid rocket booster with the SRBs.
因此，ssmes有一个空间域引擎，然后是SRB的固 体火箭助推器。
again,
再次，
it's a side view so,
这是一个侧视图，所以，
and then this here down here is below the actual platform,
然后这里这里是在实际平台下面，
and this is called a flame deflector,
这被称为火焰偏转器，
and so everything in green in this entire thing should the should be where the water is actually coming out of water is blue.
所以在整个事情中绿色的一切应该是水实际上从水中出来 的地方应该是蓝色的。
I thought that makes sense and then kind of the flames or exhaust is color coded red.
我认为这是有道理的，然后火焰或排气的颜色编码为红色 。
okay,
好的，
so there's a couple things happening here and I'll try to go through it as best I can in the most logical way,
所以这里发生了一些事情，我将尝试以最合理的方式尽可 能地完成它，
but pretty much one.
但差不多一个。
so the first thing that starts up I think it's six to seven seconds before actual liftoff is that the Space Shuttle main engines ignite,
所以启动的第一件事我认为实际升空之前的六到七秒是航 天飞机主发动机点燃，
and you can see that when the when the hydrogen burn off sparks,
而你可以看到，当氢燃烧时，火花，
which is another one of my videos when those are kind of when those have been going for a couple seconds,
这是另一个我的视频，当那些已经持续了几秒钟，
then the the SS enemies like night and then so.
那么SS的敌人就像夜晚一样。
what you have going on down here is there are these 16 nozzles which spray out water and kind of coats and coats down the on the flame deflector to absorb any of that energy from one the actual ssme start firing?
你在这里发生的事情是，这16个喷嘴喷出的水和大衣和 涂层沿着火焰偏转器向下吸收任何能量来自实际的ssm e开始射击？
I believe and I'm not sure because I couldn't find enough information on this,
我相信，我不确定，因为我找不到足够的信息，
but I believe there's something there's like 22 water nozzles inside this exhaust hole.
但我相信这个排气孔里面有22个水喷嘴。
so these two plate,
所以这两块板，
these two things are called exhaust,
这两件事叫做排气，
oles their holes going down through the actual mobile launcher platform,
oles他们的洞穿过实际的移动发射器平台，
and I think there's 22 nozzles in there.
我认为那里有22个喷嘴。
but I don't know exactly where so I didn't draw them,
但我不确切知道在哪里，所以我没画画，
but those also spray water when the SS enemies are start enough.
但是当SS敌人开始时，那些也会喷水。
so this so these um,
所以这些嗯，
since this is a side view these 16 miles,
因为这是这16英里的侧视图，
which is this kind of a blown-up view,
这是一种夸张的观点，
they're lining going across 16 of them across the flame deflector,
它们穿过火焰偏转器穿过其中的16个，
and then the water sprays out and down the flame deflector on both sides.
然后水从两侧的火焰偏转器上下喷射。
as you can kind of see here,
你可以在这里看到，
these are the openings and the nozzles and then the water flows down on the ssme side and the SRB side.
这些是开口和喷嘴，然后水在ssme侧和SRB侧向下 流动。
so so there's the 22 nozzles up here then there's its these 16 nozzles here for the Space Shuttle main engines,
所以这里有22个喷嘴，那么这里有16个喷嘴用于航天 飞机主发动机，
then for the solid rocket,
那么对于固体火箭，
boosters or SRBs,
助推器或SRB，
it's a little bit more complicated on this side.
这方面有点复杂。
so a simplified version is that so that you have the right exhaust going down through the exhaust hole and actually in the in the SRB exhaust.
所以简化版本就是让你有正确的排气通过排气孔，实际上 是在SRB排气管中。
so there's actually two holes,
所以实际上有两个洞，
there's the there's the primary flame hole and then the secondary flame hole which I'll talk about down here,
那里有主火焰洞，然后是次火焰洞，我将在这里讨论，
but pretty much there.
但几乎就在那里。
it looks like from dividuals that i've been able to look at it looks like there are two nozzles in each hole,
它看起来像个人，我已经能够看到它看起来每个洞里有两 个喷嘴，
so there's two solid rocket boosters,
所以有两个坚固的火箭助推器，
so it's kind of a top view here.
所以这里有一个顶视图。
there's two solid rocket boosters.
有两个坚固的火箭助推器。
let me back up for one second,
让我回来一秒钟，
this hole right here.
这个洞就在这里。
this is just the top view of this,
这只是顶视图，
so I'm going to just turn this on its side like that,
所以我要把它转过来这样，
so this is the Space Shuttle main engine hole.
所以这是航天飞机主发动机孔。
so this is just one big opening for all three of the of the main engines and then again,
所以这只是所有三个主发动机的一个大开口，然后再次，
there's probably 22 nozzles in here somewhere,
在这里某处可能有22个喷嘴，
but I'm not exactly sure where this dotted line.
但我不确定这条虚线在哪里。
these two data lines are just the top of the flame deflector,
这两条数据线只是火焰偏转器的顶部，
and then these there's not sixteen here but there's actually 16 nozzles lining the top of this spanning the width of the flame deflector cavity.
然后这里不是十六个，但实际上有16个喷嘴位于横跨火 焰偏转器腔宽度的顶部。
okay.
好的。
so since there's two solid rocket boosters on the stage leverage,
因为舞台上有两个坚固的火箭助推器，
two separate holes or two separate exhaust holes and in each one there's you can kinda see here I might be a little small in the video,
两个独立的孔或两个独立的排气孔，每一个都有你可以看 到这里我可能在视频中有点小，
but you can kind of see,
但你可以看到，
there's two different sections of it there's the primary flame holder,
它的两个不同部分是主火焰支架，
and this is where the space show,
这是太空表演的地方，
where the srvs are located.
srv所在的位置。
so in my notes getting around a little bit,
所以在我的笔记中走了一会儿，
but here this is the primary flame hole.
但这里是主要的火焰洞。
this is the secondary,
这是次要的，
plane,
平面，
flame hole and what's happening.
火焰洞和正在发生的事情。
is there are these two nozzles in each of the in each of the exhaust holes and those have water being fed into the exhaust hole,
在每个排气孔的每个中都有这两个喷嘴，那些喷嘴是否有 水进入排气孔，
okay and then,
好的，然后，
and then again,
再一次，
when these so the solid rocket booster lights at T,
当这些固体火箭助推器点亮T时，
equals 0 or t minus zero?
等于0或t减零？
so right at right,
就在右边，
when the time has counted down all the way to zero.
当时间一直倒数到零。
so so this this water glow,
所以这个水发光，
reforming the water from the 20 miles is already flowing and then on the SRB lights.
改造20英里的水已经流动，然后在SRB灯上。
what they found was that um,
他们发现的是那个，
the the system in here with these with these nozzles and I'll talk about these water bags,
这里的系统配有这些喷嘴，我会谈谈这些水袋，
is used to alleviate the stresses on the wings and the ailerons from when the actual SRB is ignite initially,
用于减轻实际SRB最初点燃时机翼和副翼上的应力，
because when they had their first mission so on sts-1 they found that they were getting overpressure overpressure indications on the space shuttle and they need to alleviate that alleviate those stresses somehow.
因为当他们第一次执行任务时，他们发现他们在航天飞机 上得到过压超压指示，他们需要减轻这种压力，以某种方 式减轻这些压力。
so they have this thing called the over pressure over pressure or over pressure,
所以他们有这个叫压力超压或超压的东西，
suppression or protection,
抑制或保护，
and that's where these these two nozzles in each of the SRB,
这就是每个SRB中这两个喷嘴的位置，
my exhaust holes come from and the waterbag.
我的排气孔来自和水袋。
so so I know I skip around a little bit,
所以我知道我跳了一下，
but it's but we're going to go down to here then,
但是，但是我们要去那里，
and so there's the two exhaust,
所以有两个排气管，
those there's a primary flying hole and this is the bottom view now,
那些有一个主要的飞洞，这是现在的底视图，
so we so we're like standing down here.
所以我们就像站在这里一样。
looking up into the hole and so this is for one of the solid rocket boosters,
抬头看着洞，所以这是一个坚固的火箭助推器，
so you can see the nozzle is regular nozzle for the solid rocket booster and this is the primary flame hole.
所以你可以看到喷嘴是固体火箭助推器的常规喷嘴，这是 主要的火焰孔。
so this is where the actual you know when it lights.
所以这就是你知道它实际亮起的地方。
it'll come right out of this hole and this is the secondary flame hole so in the primary flame hole.
它会从这个洞出来，这是二级火焰洞，所以在主火焰洞中 。
this is again also just looking at video picture,
这也只是看视频图片，
but it looks to me like there are these water bags lined around the actual rocket booster in the primary flame hole and from the video it looked like.
但在我看来，这些水袋在主火焰洞和视频中看起来像是在 实际的火箭助推器周围。
these were yellow,
这些是黄色的，
like yellow water bags,
像黄色的水袋，
and then these over here are lining the secondary flame on these look like they were red water bags and again these two things here are these two nozzles that are just flowing water,
然后这些在这里的二次火焰衬里就像它们是红色水袋一样 ，这里的这两个东西再次是这两个只是流水的喷嘴，
and so these water bags are just holding water they're not they're,
所以这些水袋只是拿着水，他们不是，
not injecting water out into the into the actual flame holes,
不将水注入实际的火焰孔，
so what they would do is they would dampen the blowback pressure from when the SRBs were initially ignited kind of.
所以他们会做的是它们会抑制SRB最初被点燃时的反吹 压力。
similarly,
同样，
to how like a water balloon,
如何像水气球，
if you drop it on,
如果你放下它，
you know the pavement sometimes it doesn't break,
你知道路面有时它不会断裂，
it will just absorb the energy.
它只会吸收能量。
so that's what these would be doing with the acoustical sound waves.
所以这就是声学声波所做的事情。
okay,
好的，
so then that's all well and good.
那么这一切都很好。
so when the so before going back again a little bit before the actual launch,
所以在实际发布之前再次返回之前，
the SS enemies are lit the water's flown here.
SS的敌人点燃了这里的水。
so the water forum here the front flowing from the 22 nozzles in here and then when the SRBs are ignited.
所以这里的水论坛前面有22个喷嘴从这里流出，然后当 SRB被点燃时。
you may have the overpressure suppression system attract these two nozzles and then the water bags in the exhaust hole and then,
您可能有超压抑制系统吸引这两个喷嘴，然后吸入排气孔 中的水袋然后，
when the shuttle lifts off once,
当班车升空时，
I think it's a it says in some of these documents that when it's about 300 feet off of when it's risen 300 feet above a platform.
我认为这是在一些文件中说，当它比平台上升300英尺 时大约300英尺。
you start getting the acoustical energy reflected off of the metal plates on the mobile launcher platform of the MLP seen here and to dampen this out.
你开始从这里看到的MLP移动发射器平台上的金属板上 反射出声学能量并将其抑制掉。
they have the six huge nozzles called rain birds which flow about 300 thousand gallons of water over the actual platform.
他们有六个巨大的喷嘴，叫做雨鸟，在实际平台上流过大 约30万加仑的水。
the pipes so there's a water tower located a little farther away from the platform and it's it's.
管道，所以有一个水塔位于离平台稍远的地方，就是这样 。
the height is about 290 feet off of the ground,
高度离地面约290英尺，
and these pipes feed each of the six there's only two shown here but feeds each of the six rain birds and the pipe that leads from the water tower to these rain.
这些管道中的每一个都只供给六个，这里只展示了两个， 但是给六只雨鸟以及从水塔通向这些雨水的管道中的每一 只喂食。
birds is seven feet in diameter,
鸟的直径是7英尺，
which is extremely large,
非常大，
and then they fly these nozzles,
然后他们飞起这些喷嘴，
which are there less than seven feet.
哪有不到七英尺。
I think a couple of them are maybe like 40 inches or I guess it'll be about 4 feet and then like two and a half feet diameter nozzles and those just flood the the mobile launcher platform with water to absorb the energy after the space shuttle is lifted off higher than 300 feet and I guess that's kind of an overview of the sound suppression water system I used.
我想其中有几个可能是40英寸或者我猜它大概是4英尺 然后就像直径2.5英尺的喷嘴那些只是在移动发射器平 台上淹没水以吸收航天飞机后的能量升高超过300英尺 ，我想这是我使用的声音抑制水系统的概述。
if you have any questions,
如果你有任何问题，
let me know or if I didn't explain something well enough,
让我知道，或者如果我没有解释得足够好，
let me know and I'll try to fix it or if I'm wrong on any of this stuff,
让我知道，我会尝试解决它，或者如果我错了任何这些东 西，
because this is all it's not it's not just speculation,
因为这不仅仅是猜测，
but I this is from visual clues,
但我这是来自视觉线索，
where I think that these are the water bags,
我认为这些是水袋，
but I'm not a hundred percent sure.
但我不是百分百肯定的。
so if you have any information,
所以，如果你有任何信息，
please let me know.
请告诉我。
thank you.
谢谢。
