The semi-cryogenic engine project was sanctioned in 2009.But work has already been started before the sanctioning of the project. And its main sub-systems like gimbals pumps,.... were developed. It will source the common components from its cryogenic cousin. According to ISRO the first semi-cryo will be ready to deploy in 6 years after the sanctioning of the project which mean by 2015.
Various test facilities have already been in place. The reason it will take long gestation periods is, because its of 2 MN class engine.
UMLV was high on ISRO agenda. Parallel development works are on for the development of CUS-60 with design work on the drawing board and awaiting sanction from the GOI.
Even if we forget the cryogenic engine, SCE itself will propel the nation as a leading player in the space tech
For extra lift, all ISRO has to do is clustering of semi-cryos for boosters and first stage.The very same concept for heavy lift vehicle.
This is how I see the future of Indian space program:-
By 2013 GSLV-MKIII with CUS-25 flight tested
By 2015 development of SCE completed
By 2016 GSLV-MKIV with 4S200 boosters capable of launching 6t to GTO
By 2017 GSLV-MKIIISC with SCE-110 instead of existing L110 flight tested ( there by increasing the payload capability to 6t to GTO and 12t to LEO)
By 2018 GSLV-MKIIISC-XL with 4S200+SCE110+C25 capable of carrying 9t to GTO and 16t to LEO
By 2020 UMLV-MKI with 4 S230 + SC500 + C60 capable of carrying 15+tons to GTO and 31t to LEO
By 2023 UMLV-MKII with 8 S230 + SC800 + C60 capable of carrying 85t to LEO
By 2025 HLV-MKI with 4 SC460+SC800+ C100 capable of carrying 100t+ to LEO
By 2030 HLV-MKII with 8 SC460+SC800+ C100 capable of carrying 200t to LEO(we only need this configuration if planning to build a colony in space or a colony on Moon for transporting prefab structures and machinery for mining purposes and solar panels for power generation,.....
The Above is only when conventional UMLV is considered.
When the non-conventional part is taken into account,
By 2017 RLV becomes operational with regular flights to LEO.
By 2020 TSTO becomes operational
By 2025 SSTO becomes operational
THANK YOU guys for bearing me here
The Saturn V moon rocket weighed 3000 tons and could put 100 into low earth orbit (around 200 km up, not to be confused with GEO (around 35000 km), which is used for GPS and communication satellites because at that orbit a satellite will stay stationary over its part of the Earth's surface. Mass to GEO is a lot lower than to LEO.) The Space Shuttle orbiter could only launch into LEO and weighed 60 tons (the whole stack, boosters and all, weighed 2000 tons) but effective cargo (in the payload bay) was only 20. The European Ariane V, roughly the size of the GSLV III, can put around 15 tons into LEO and launches two satellites at a time.
The GSLV will have a lower mass to LEO but a similar one (around 6 tons) to GEO. It will weigh 600 tons.
It takes a lot of mass to put a little payload into orbit.
Dont think Cryo engine and semi cryo have anything to do with each other. Semi cryo is developed for stage 1 and 2 and cryogenic engine for third stage. Cryo for GSLV mark 3 static will start mostly after the success of GSLV mark 2 and 2013 is extremely doubtful. Semi cryogenic research is slow but should catch up pace after Mark 3 .
From ^^^^^^^^^^^ this to this VVVVVVVVVVVVVVVV
The journey has been phenomenal.
Our hard work, talent and dedication have brought our nation to this level.
Proud to be Indian.
Indeed, if GSLV III will test successfully it will boost India space capability greatly.
There is nothing wrong with truss, it is just one of the interstage design. Truss helps save a lot of weight.
Then
Now
All I can say is:
