LVM3/GSLV Mark III News, Discussions, Updates and Reports

[TopWatcher]

New things coming in portfolio:

SCE-200 based SC120, SC160 and SC200 main stages instead of Vikas series.
Enchanced CE-20.
LM20 and LM40 as new methane based upper stages.

When we could see these engines launches?

When we could see these engines launches?

SCE-200 - Minimum 2-3 years from now.
LM engines in last quarter or by end of this decade.

I dug this up while looking for something else. What is wrong with some people? Why the negativity, and lack of appreciation for actual, genuine *work* and effort? How is launching 36 satellites something minor? Sheesh!

If the idea was merely to illustrate that other countries, including China, are ahead of India in number of launches, as well as in payload capacity, that can be done without denigrating ISRO's efforts. Also with some knowledge of history and respective budgets. When India one day lands a man on the moon( assuming this is a goal) these are the types of characters who will ask "Why is this a big deal, the US did it in 1969"

Criticism for the sake of just doing "criticism" to look cool and "englightened".

Both US and PRC have been operating LVM3 class rockets since 90s.
Added both have incomparable aerospace industry and can churn out much more production than India.

India simply outdoes every great power on planet except US, Russia and China going against its economic size. India sustaining 6-8 launches an year itself makes it surpass JAXA (ESA's low launch frequency case being different, every Ariane 5 is an HLV).

LVM3 means we can now progress to heavier and heavier payloads.

Semi cryogenic engine with the first level of 2000 K Newton is just begun the testing of SC 200 with a thrust of 2000 kn which is more than double (Correct me if I am wrong) the thrust of s200 booster. I thing L110 and s200 should be replaced with SC engines. Replacing S200 with SC 200 will boost the payload capacity by atleast 50 PC.

Blue Origin keen on using LVM3 for commercial space activities

BENGLAURU: Jeff Bezos’ Blue Origin is keen on using India’s GSLV-Mk3 or LVM-3 as a crew capsule to service its Orbital Reef, a Low Earth Orbit (LEO) space station being designed for commercial space activities and tourism uses, Isro chairman S Somanth confirmed to TOI in an exclusive interview.

Somanath said: “We are exploring … In fact, we’ve already discussed it with Blue Origin and they are very keen to consider this option of LVM-3 becoming a crew capsule mission to service the Orbital Reef. It is a possibility and we are engaging through IN-SPACe (Indian National Space Promotion and Authorisation Centre).”

On the challenge of integrating a docking system that is compatible, he said standard docking systems are in the public domain.

“...Whoever can design a docking system that matches with the US design and standard, can be used. However, we will still need to have agreements with agencies to try it out given that there are multiple interfaces — electrical, mechanical and so on. It is not just one document, we will need to work with them to develop it. We will do that.

Further, elaborating on other possibilities as announced during Prime Minister Narendra Modi’s state visit to the US, Somanath said it was possible to use LVM-3 in cargo missions to the ISS in the future.

On astronauts training for Gaganyaan flying on a joint Isro-NASA mission, he said: “Possibility of them flying in a joint Isro-NASA mission cannot be ruled out at this moment. However, we will have to see if they are the right candidate for an US mission, or if we’ll need a different set of people who’ve not been experienced with the Russians…the pros and cons will need to be discussed. But I believe that it should be possible to consider them for the US mission at this moment. They are anyway experienced and they are destined to fly. It is possible.”

At present, the four astronaut-elects are going through various phases of training and as reported earlier by TOI, they have completed the first semester of the Indian module after arriving from initial training in Russia.

“The second semester which involves engagement with other academic institutions is progressing while we’ve started the simulator experience at some level but more simulators are being made now. This year, the plan is to complete the second semester training and begin the full-fledged simulator training at some level. Astronauts are giving some feedback on simulators as their experience in Russia is so enormous. We are designing and building simulators and astronauts become the design feedback community and they are participating with us on this,” Somanath said.

Pointing out that India has so far not developed the training environment in the country, he said, the same has to be done using the experience of these astronauts. “Currently, we are manufacturing and installing the simulators. Software and other front-end simulators are already made but we have to make a big capsule simulator,” he added.

Great news but we need to upgrade GSLV MK 2 so that we can launch up to 6 ton with it in LEO and save lots of money. Semi cryogenic engines are key. Liquid and solid stages should be replaced with semi cryogenic stages.

Reposting from @Vamsi's findings.

Spoiler: Tweets

Interesting presentation by the chairman-
So, ISRO is considering RD-181/191 for the interim SC120 until SCE-200 is completed.

RD-181 is the RD-191 variant that 'was' used on the Northrop's Antares rocket.

#ISRO

Guess they have surplus RD-181s as Antares is now basically cancelled due to the war.

If that goes on, LVM3 will be among primary rockets for international launches (and SSLV for small payloads).

LVM3 payload increase using the SC120 and C32 stages: 640kg payload gain to GTO with SC120 484kg payload gain to GTO using C32 Upgraded LVM3 payload to GTO - 5.1ton

 

[Raj Malhotra]

Only 640kg payload gain due to SCE seems very low. I thought gain would be 2000kg+

 

[Varoon2]

The weight/mass of the Insat-3DS is now 2275kg, increased from about 2075, or 200 kg. Could this additional weight be part of the reason for the delays, the extra parts or components had to be fabricated, tested and integrated on the satellite.
