I Really Like The Video LE-5B-2 Liquid Rocket Engine Firing Test From Your

[bundawartini]

Your Video LE-5B-2 Liquid Rocket Engine Firing Test Is Very Useful Sharing

[unkeihokusai]

This is LE-7A of H-IIB

[bai0089]

Is this LE-5B-2 ?

[BlackForgeSteel]

Liquid fuel?

.....

Kinda volatile for rockets.

[ti994apc]

@BlackForgeSteel Liquid fuel is much better than solid rocket fuel. Solid rocket fuel was one of the reasons Challenger exploded. Also one of the reasons Wehner Von Braun left NASA. Also, there was the last 2 India launch failures, the Taurus rocket failure, the last Titan IV (which was the most expensive rocket failure ever), and the Delta II explosion (which destroyed a parking lot), all of which were due to solid rocket booster failure.

[BlackForgeSteel]

@ti994apc I got them mixed up apparently.

[outback1054]

mitsubishi made it.

[TooMuchGass]

That was japaneese with french accent

[carpetmonk]

thats not a frech feed?.

[thiago497150]

How hot is it?

[doverdx]

@thiago497150  about 6000F or 3300K for LH2/LOX

[amebabameba]

This is not LE-5B-2 of the second stage. This is LE-7A of the first stage of H-IIB.

[EndeavourLaunch]

Very similar design to the SSME.

[ModernGeek]

Looks like a copycat of the SSME platform.  We just need to go back to disposable F-1 Engines.

[baillou2]

yes it's japanese. You can clearly hear: Go, shi, san, ni, ichi... etc which is japanese counting down, then the man starts counting up on ignition.

[kuroneko3377]

Mitsubishi-H2B　Mitsubishi-LE7A　engine

[ManOfMeans]

Those engines look the way my ass felt after eating my mother-in-law's tacos lmao

[amourdutigre]

It is Japanese. Look at the website in the comments section above.

[barthoedemaker]

FRENCH

[COLOURIOT]

i thought so, but the count from 0:23 sounds a bit like Japanese i may be wrong

[acidlanka]

why are so many comments voted down???

[MilanWraith]

dont worry.

they are just bored and antisocial people.

and my comment will also be voted down i guess :D

...

so, come on guys, bet you cant vote my comment to -10 in two days! haha!

[Sereniance]

Holy crxx. I love those engines go boom

[douro20]

These are Mitsubishi engines...

[PeekoneX]

無知ですまないけれど、クラスターエンジンならＬＥ－７Ａじゃな­いでしょうか。

ＬＥ－５Ｂ－２でもクラスター化のテストをしたんでしょうか。何­のため？

[AL3J4NdR001]

fuck you

[fusianasan8]

はいはい

ふぁっくゆーふぁっくゆー

[midlothianboy]

怪物だな～

[starbabe58]

that is cool

[PaleAlejandro]

more info please.....like why should I care about this rocket .... fill out a description perhaps ..... narration ........ ANYTHING!!!

[Foxx1981]

This is more for people that are actually interested. Also: good job on validating the stereotype that yanks are dumb fucks wanting to be spoon-fed everything.

Go watch the Discovery channel instead of leaving moronic comments about how you're entitled to being spoon-fed information.

[rkrupski]

I wonder if the start sequence for this engine is as complicated as the SSME?

[doverdx]

Oops. Turns out this is the LE-7A so the cycle is probably quite similar to the SSME.

[Membrane556]

@doverdx

You're right it is a staged combustion engine like the SSME.

Though it's design is probably more closely related to the Russian RD-0120 then to the SSME.

The vac ISP of it is around 440sec a little lower then the 455 and 454 for the SSME and RD-0120 but still very respectable.

[Zoomer30]

Looks a lot like the SSMEs even has the blue shock diamond.

[dothamster]

It should be clustered LE-7A!Not LE-5B

[jixolros]

Of course!
