Semi-cryogenic Engine: ISRO Charting a Revised Plan

THIRUVANANTHAPURAM: Hit by delays, the Indian Space Research Organisation’s (ISRO) efforts to create a rocket engine which uses kerosene as propellant is getting a revised plan.

The new ISRO chairman A S Kiran Kumar has asked the Liquid Propulsion Systems Centre (LPSC) to prepare a brand new-schedule for the semi-cryogenic engine project as it is running behind schedule. As per the original plan, the semi-cryogenic engine should have been ready by 2014, but delays in setting up test facilities at the LPSC unit in Mahendragiri, Tamil Nadu, had dragged the project.

Kiran Kumar, who took over as chairman in January, reviewed the progress during a recent visit to the LPSC HQ in Valiyamala, Thiruvananthapuram, and recommended a revised plan.

The new schedule for the semi-cryo engine will be readied on the basis of the report prepared by the LPSC, LPSC director Dr K Sivan said. ‘’We are making all efforts to speed up the project. The ISRO chairman has recommended a revised plan and we are working on it,’’ Sivan said.

Unlike a cryogenic rocket engine which uses liquid hydrogen as propellant and liquid oxygen as oxidiser, a semi-cryo engine substitutes the liquid hydrogen with a refined form of kerosene (RP-1).

Compared to liquid hydrogen, kerosene is cheaper, stable at room temperature and safer to handle. On a positive note, this project which will help slash launch costs by a considerable margin received a fresh shot in the arm on Saturday. The Union Budget 2015-16 has earmarked Rs 150 crore for the development of the semi-cryogenic engine.

The Cold Flow test facility required for the project is ready at the Mahendragiri unit. At a later stage in the engine’s development, an integrated engine test facility also will be set up there.

Spacefaring nations like Russia and the US have been using the semi-cryo for decades. The Union Cabinet approved ISRO’s plan in 2008, with an estimated cost of Rs 1798 crore. Then, the idea was to have the engine ready by 2014.

‘’The semi-cryogenic engine will facilitate applications for future space missions such as the Reusable Launch Vehicle (RLV), Unified Launch Vehicle (ULV) and vehicles for interplanetary missions,’’ the government had said in 2008.

why didn't the sanghi isro mention spacex... that private company achieved within ten years of establishment what the isro couldn't in 50+ years... and spacex doesn't have the huge government funding that the sanghi isro has.

also, what happened to isro wordings like "state-of-the-art cryogenic technology" that it had been pompously shouting for 15+ years... isro saw the clear success of spacex rockets which use kerosene/lox fuels and changed their tune.

by the way, spacex is also looking at methane as fuel.

spacex has elon musk, who does isro have??

oh... the usual hyper-nationalist indians here will again say to me... "oh, spacex was given technology by nasa"... excuses for incapability, i say... bloody excuses... what happened to those "38 percent indian scientists" supposedly the most important part of nasa?? did those fellows transfer to spacex or did they refuse to help isro?? and why hasn't all the temple-going-and-coconut-breaking rituals of isro given isro real success ( like spacex ), and when will a sanghi

i see spacex sending a human to spacex earlier than isro... in fact, "mars one" has a supremely better chance of landing fifty people to mars than isro has of getting ten people into low earth orbit.

the sanghi isro must be disbanded and replaced with a pan-south-asia space agency headed and staffed by actually sensible people... better yet, a single human-travel space agency is better than national ones... maybe the chinese government and american government will not join, but others will.

stop talking utter rubbish. all of 'specex technology' is supplied by nasa!!! you think a private company can develop a rocket like falcon in that much time? stick to topics that you can sell bs easily. and stop dragging your religious bigotry into every thread!!

wtf is sanghi isro you idiot?

 

[ni8mare]

why didn't the sanghi isro mention spacex... that private company achieved within ten years of establishment what the isro couldn't in 50+ years... and spacex doesn't have the huge government funding that the sanghi isro has

spacex is there is for 14 years..................and isro is not for 50 years

also, what happened to isro wordings like "state-of-the-art cryogenic technology" that it had been pompously shouting for 15+ years... isro saw the clear success of spacex rockets which use kerosene/lox fuels and changed their tune.

stop ranting .................SCE has been proposed long ago

spacex has elon musk, who does isro have??

we have our own people

oh... the usual hyper-nationalist indians here will again say to me... "oh, spacex was given technology by nasa"... excuses for incapability, i say... bloody excuses... what happened to those "38 percent indian scientists" supposedly the most important part of nasa?? did those fellows transfer to spacex or did they refuse to help isro??

you can deny all you want ............

and why hasn't all the temple-going-and-coconut-breaking rituals of isro given isro real success ( like spacex ), and when will a sanghi

so what will done????????.......................... namaz

i see spacex sending a human to spacex earlier than isro... in fact, "mars one" has a supremely better chance of landing fifty people to mars than isro has of getting ten people into low earth orbit.

by using nasa technology

the sanghi isro must be disbanded and replaced with a pan-south-asia space agency headed and staffed by actually sensible people... better yet, a single human-travel space agency is better than national ones... maybe the chinese government and american government will not join, but others will.

stop bringing your religious bigotry ............................and which pan south asian agency you are talking about

who will be those sensible people lead ?

Isn't it very easy to type rants sitting in an armchair, rather than doing some real work to improve the situation?

every revolution begins with a rant from a armchair... the laborer and the wage-slave office worker and the triple-college-degree distinction-rank college student will never start a revolution.

and because i rant, i have led a difficult life... the wage-slave leads a most careless life despite his life bringing him small and big troubles every day.

essay on this from another man, written more finely than me... ( http://www.mathaba.net/news/arab.shtml?x=628361 ).

stop talking utter rubbish. all of 'specex technology' is supplied by nasa!!!

there we go.

you think a private company can develop a rocket like falcon in that much time?

right... there is nothing call human genius, innovative spirit and risk taking... brilliant.

wtf is sanghi isro you idiot?

ISRO chief visits Tirupati temple ahead of satellite launch

this fellow is the chief of india's national space agency... did i ask him to regularly visit temples on my behalf??

spacex is there is for 14 years..................and isro is not for 50 years

falcon-9 first visit to international space station was in 2011.

check isro's year of establishment... i have written of this before.

we have our own people

none of them a true genius... please stop justifying them just because they are from the country you and i live.

you can deny all you want ............

lovely.

so what will done????????.......................... namaz

i haven't prayed in about 18 years... i don't know what is prayer.

by using nasa technology

nasa has not much part in "mars one" program... it will be private companies like "surrey satellite".

stop bringing your religious bigotry

i am bigoted against unthinking mysticism from every religion community.

............................and which pan south asian agency you are talking about

who will be those sensible people lead ?

such a agency must be created because a side effect will be drastic demilitarization in south asia... and those sensible people will lead truly curious-about-nature people like those three indian citizens who have been short-listed within "mars one" program.

 

[Srinivas]

Yes Hindu GODs are not real gods and when some one visits their own GOD during the missions, it hurts our ego because of our teachings. Simply deny the achievements of that agency. Since GOD is our monopoly !

 

[lasttry]

oh so you are saying ISRO chief has not right to practice religion. so when abdul kalam was drdo chief and he did a namaz when in office, drdo would have been a jamaati organization.

this is the kind of rationale that emerges when you think with your bottom.

 

[Bornubus]

@jamahir

I would have no problem if ISRO muslim chief would have gone to Macca or any sufi shrine for the success of ISRO missions in future......BTW kalam is the big fan of ISRO

on topic: is ISRO cryogenic program wil replaced by this semi cryo engine

 

[MokshaVimukthi]

allah hu ackbar ......... down with ISRO ..... up with ISIS.

are you pretending that i am not to the far left?? isis to me is the same as rss and ram sena.

@Srinivas @lasttry @Bornubus

i say again... (a). i haven't prayed in about 18 years... i don't know what is prayer, (b). i am bigoted against unthinking mysticism from every religion community.

besides, isro is also a thankless bunch... there is no isro rocket named "tipu sultan" who was the prime propagator/innovator in rocketry and he also being ruler of mysore state ( which resides now within the same karnataka state as the headquarters of isro )... there is no isro rocket named after some chinese great man ( china being the place where rocketry was born )... so it is isro which is bigoted, not me.

Simply deny the achievements of that agency.

what are the achievements of isro?? a camera in mars orbit, with the entire rocket/bus/satellite system built on technology transfers over decades mostly by the west?? a sensor above moon "discovering water", with the sensor being of american devising, and the entire episode turning out false with no real water being discovered?? becoming the main producer of useless satellites with no hopes of sending humans to space anytime within the next ten years??

Oh unlike others I KNOW your true nature ..... you are a closet Jihadi, disguising your hate as "socialism".

The only place that deserves the name "tipu sultan" is the public urinals and toilets so that Indians can take their daily dump in his name.

The achievements of ISRO are well known to all Indians and they do not need certificate from me or anyone.

Your ignorance and hate is Your Burden. Do not expect others to lighten your load.

Its you who bought relegion in this thread.....and don't care abt some mars missions....all i care is that we are capable of launching our own satellites that's all

and once again i wont mind if isro chief go to Macca for the success of The missions

so plz...

 

[Srinivas]

Dude you are confused here or deliberately trying to side track the discussion!

why would any one name the rocket with chinese name, Isro is an Indian organization?
There are enough acknowledgements of the things which Tipu has done for the people sake not for his kingdom sake.
If you feel allergical to our GODs and our worship kindly restrain from passing bad comments. If Yehova is allergical to other kinds of worship that do not mean others should stop.

ISRO is doing well and is expected to do well in the future, it is the hard work and dedication of scientists that will take this organization to the peaks. Worship is their private affair.
