[Jai Bharat]

Why did India take the cryogenic route instead of semicryogenic one....or its the natural evolution?
Semicryogenic engine seem less complicated than cryogenic ones...
Somebody shed some light!!

Upper stages of rockets need very high efficiency and cryogenic engines are most suited for that, however it is more expensive.

Semi-cryogenic engines are better for initial stages, and have cheaper fuel costs.

In the future ULV, which will be the main launch vehicle when it is ready, will use solid boosters, semi-cryogenic core stage, and cryogenic upper stage.

FUTURE PLANS

ISRO is designing heavy-lift launch vehicles with capabilities in the range of 6–10 tonnes in GTO. For this purpose, the following propulsion systems are being pursued:

1. A 200 tonne propellant loading LOX and kerosene booster stage powered by a 2,000 kN thrust semi-cryogenic engine operating on stage combustion cycle.
2. A 50 tonne LOX-LH2 propellant loading cryogenic stage powered by twin CE 20 cryogenic engines.
3. A 10 tonne LOX-LH2 propellant loading cryogenic stage powered by a CE 20 cryogenic engine.

Any reasons why isro did not concentrate on semi cryogenics earlier?
It seems less complicated than cryogenic one...

They went for hypergolic fueled engines

I know about a 6mt capacity ULV but 10t?

How far are we away from testing first prototype of semicryo tech?
Heard it is in 2016....is it true?

This ain't the ULV,This is the heavy lift vehicle

We will be ready with the engine [SCE-200] in six to eight months

This ain't the ULV,This is the heavy lift vehicle

HLV concept which is under study by special team since 2010 is a super heavy launcher concept (Manned Moon and other long term mission.)
This rocket family has capacity >20t at least.
10t must be developed as a platform just like 4t capacity GSLV Mk3 is being upgraded to get capacity of 6t.

No,this one has a gto capability of 10 tonne & leo capability of 25

 

[rational]

No,this one has a gto capability of 10 tonne & leo capability of 25

I think ISRO doesn't need to hurry we need more improvement in metallurgy & should go for 600 kN semi cryo along with 2000 one ,we can increase the payload capacity to GTO to 12 to 15 tone

 

[Bad Guy]

No,this one has a gto capability of 10 tonne & leo capability of 25

Could be a part of project as they need to make an HLV before SHLV. Concept publicized in 2010 was of super heavy.

There are many HLV designs being studied by ISRO .... re-posting an old post of mine .


Heavy Lift Launch Vehicle concepts

ISRO have carried out study of 4 different concepts of HLV to date . These are explained below in random order .


Concept-1

Payload Capacity : 25 tons to LEO (10 tons to GTO)

A Heavy lift Launch Vehicle capable of placing up to 10 ton class of spacecrafts into Geosynchronous Transfer Orbit is currently under study by a project team. This new generation launch vehicle will derive its propulsion modules from LVM3 as well as from new developments, which include :

1) semi cryogenic booster stage, SC200
2) larger solid strap on boosters as compared to S200 strap on motors used in LVM3 (S250) and
3) a larger cryogenic upper stage (C50).

Concept-2&3

Concept 2&3 together was supposed to carry out a human mission to moon . It was first shown in a presentation by ISRO at the IAC 2009 .

Concept-2 = Crew Launch Vehicle
* Architecture - 4 S230 + SC500 + C60
* Liftoff weight - 1690 tons
* Capability - 31 tons to Low Earth Orbit
* Payload - Crew Module (6 tons) + Service Module (25 tons)

Concept-3 = Carge Launch Vehicle
* Architecture - 8 S230 + SC800 + C60
* Liftoff weight - 3075 tons
* Capability - 84 tons to Low Earth Orbit
* Payload - Earth Departure Stage (67 tons) + Lunar Descent Module (17 tons)

Concept-4

Single LV capable of Lunar Man Mission with payload capacity of 100tons to LEO

This looks like a single LV capable of replacing two LV of concept-2&3

Sounds pretty good.

eppa ??

The information about stages and engines are new,I suppose

No CE-60

1) semi cryogenic booster stage, SC200
2) larger solid strap on boosters as compared to S200 strap on motors used in LVM3 (S250) and
3) a larger cryogenic upper stage (C50).

That's wrong

1. A 200 tonne propellant loading LOX and kerosene booster stage powered by a 2,000 kN thrust semi-cryogenic engine operating on stage combustion cycle.

2. A 50 tonne LOX-LH2 propellant loading cryogenic stage powered by twin CE 20 cryogenic engines.

3. A 10 tonne LOX-LH2 propellant loading cryogenic stage powered by a CE 20 cryogenic engine.
