Skyroot Aerospace - Updates & Activities

That went up like a Sivakasi diwali rocket. Fast and Furious!

It's called regenerative cooling, yes almost all liquid engines need it

Circulation and pressure might have to be more governed in staged combustion as compared to gas generators (that explains why LVM3 CE-20 is more reliable than GSLV CE-7.5). Wondering what will happen to SCE-200.

 

[Swesh]

What about payloads ?

No atmosphere payload only payloads to evaluate vehicle performance.

SCE-200 is even more complicated than CE-7.5 . SCE-200 uses oxidiser rich cycle while CE-7.5 uses fuel rich cycle..... oxidiser rich cycles are more notorious than fuel rich ones...they have to be extra careful with SCE-200

@Indx TechStyle @Swesh did you notice the cracked metal sheet like thing from onboard footage?? What is it ??

I noticed

 

[Vamsi]

Also did you notice the telemetry loss before splashdown?
Telemetry was lost at 12kms altitude

Given what happened to CE-7.5 and eventually GSLV, I actually expect delays and possibly even program scrapping for failures of SCE-200. Chinese built a smaller YF-100 and chose to cluster them.

While SCE-200 is far bigger, comparable to NASA's RS-25. Complexity and chance of failurr will be certainly higher than Chinese engines.

both YF-100 & SCE-200 belong to same family, both are derivates of RD-120 in one way or another....failure of CE-7.5 during GSLV D3 flight is due to the lack of high altitude test facility at that time, while the recent failure is because of some pressure drop,which is easily rectified.But yes, they have to be very careful with SCE-200

Is it safe to say fuel rich rockets like CE-7.5 are more suitable for reusable launch vehicles?

I have the same question as well. Not sure if the damage is limited to exterior or structural

If it is LH2-LOX engine then Yes, but if it is Kerosene-LOX/Methalox engine, then Oxidiser rich is better, because it offers higher specific impulse

They lost telemetry at 12km altitude, I'm thinking that casing might not have survived, but still it survived the ascent flight though,this is what most important

 

[Suryavanshi]

After achieving every milestone, the irritating pungent voice and low quality coverage of DD confirms and convinces me that yes, certainly India has done this.

It is so bad that it has become iconic and unique to us.
Let's keep it.

Chinese state media, banners layout and coverage has it's own old essence. So is ours.

When will they launch vikram 1?
Also agnikul is going to launch their agnibaan this year

Is thier any greater tech than semi cryo engines in space launch vehicle?

3rd quarter of 2023 for Vikram -1
