If u see skyroot rocket camera video, rocket is rotating , why ?

It never happen with ISRO rockets !

YF-100.

That's their highest thrust rocket ?

spin stabilization

But it never seen with pslv , gslv. Does spin stabilization required for sounding rockets ?

Congrats Skyroot! The female commentator did a good job, and had a very pleasant voice. Yes, too many scenes of VIPs. It's okay to show it once or twice, not every few minutes.

yes, welcomed fresh voice among the usual perfaarmance Naarmal!

Naarmal stuff has sailed a bit too too far!

YF-130 was recently tested

What's the timeline of launch though?

Folks can u pls differentiate sce-200, sce-120, ce-32(recently tested)
Along with minor specifications and current status

SCE-200 = ISRO's 2.03MN semi-cryogenic engine under development. It will boost LVM3's capacity by 50%, it's clustered configurations will power India's future HLV and SHLV rockets.
SC120 = Name of future main stage of LVM3 which will contain 1 x SCE-200
CE-32 = Name of future upper stage of LVM3 containing 1 x CE-20 cryogenic engine. It's an improvement over current C-25 upper stage with same CE-20 engine.
C32 though will have more fuel than C25, more engine burn time and hence will produce 10% more thrust than C25 (alone increases payload capacity to GTO by 450 kg).

That's their highest thrust rocket ?

Yes, YF-100 is currently highest thrust engine of PRC.
YF-130 is under development and will take a bit of time. It's massive.

God i wish we can make long march 5 equivalent by 2030

Likely 2035. LVM3 will remain testbed for SCE-200 for first few years.

@Vamsi What are the perks of having an LO2/LH2 engine like RS-25 US uses and how feasible it's for India to make it?

It's all funding related

Depends on the design

LH2/LOX engines for lower stage are inefficient,since LH2 has very low density,they require large tanks thus, lower stages have very high dry mass, & also it's difficult to reuse them,need very high maintenance, because TeT will be very high for them, need high end metallurgy.They have low T/W ratio.

Technically it is easier for us to develop a Gas Generator cycle engine like French Vulcan or American RS-68, after all French Vulcan is loosely based on 67KN HM-7B engine

If we want Heavy Lift Expandable LV like Delta 4 then we should develop RS-68 like low cost engine, if we want Reusable LV then we should go for Methalox engine

Splashdown means parachute landing ,right ??

Did we recover payloads ??

Nope

It transmitted data till splashdown

It transmitted data till splashdown

Or was supposed to transmit

FYI, all the relevant Chinese enginesView attachment 182677
9 engines that CASC plans to develop in 2021~28:
200t FFSC metholox
500t staged kerolox
220t staged hydrolox
360t staged kerolox High-thrust staged hypergolic
85t gas-generator kerolox
80t gas-generator metholox
8t staged hypergolic
25t expander hydrolox

It's always encouraging about India's growth story when I see it making forays and strides in every field and sector, aerospace, research, naval, economics, military and reviosionism (refuting western influenc). But entire ego shatters after watching at China which dwarfs India in all those aspects everytime. It has sounded to start even funny now.

Though, the larger part of the issue remains meagre budget India allocates be it for fighter planes, naval expansion & shipbuilding, city planning and space research, I'm wondering whether India will able to spend that kind of CAPEX on research even when India's economy crosses $10 trillions. They put different goals. No new cryogenic engine might be needed by India as CE-20 can be clustered and so is with SCE-200.


Coming back to pattern, all USSR, China and even now Iran seem to have been testing different cycles and stages even on similar size of rockets. They produce 3 or more rockets at once for one weight class without bothering to move towards other.
India meanwhile everytime moved focus on acquiring next class of payload capacity based on previous system once it attains one sort of launch capability. So, in their case, it might have been about gaining engine tech. India meanwhile only remained content with achieving a particular launch capacity and didn't bother to develop that class of rocket with some different configuration again.

WTF?? Why are the founders sitting back??

Not a great conference room design. In future there should multi-purpose Auditorium sort of area where all things should be covered.

They are building one, specially for Gaganyaan
