who gives a crap to media
it was a historic day for india

 

[mahesh]

will the cryogenic stage engine wil be recovered back ? or will it burn out in space?

Remember this? well done ISRO. took 3 long years but finally gave a fitting response to gutter British press.

A great achievement of which India can be proud of.

Thanks for your welcome and reply.
Being a new member, I don't have privileges like pasting link etc. That is why mentioned the Chinese SLV model and wiki site - so that one can look into it. I also request moderators to transfer my post into new thread, if they prefer it.
Nonethless - following is info from wiki:

Welcome to DFI. The reason here is purely due to the different structure and fuel used by the GSLV and the Long March 3 family of rockets. In the GSLV the core engine is a cluster consisting of 4 liquid boosters that burn N2O4/UDMH liqiud fuel along with the S139 solid core engine which has solid fuel as - HTPB (solid) . Though solid fuels are easier to manage and store... the trade of is that the tank has to be made of thicker material than for storing low density liquid fuels. Hence the tank structure along with the fuel to much more heavier than a comparatively sized liquid fuel stage.
The chinese long march 3 series is relatively simpler in thier rocket stacking ..ALL three stages and booster are liquid fuel. The first two stage + booter have N2O4/UDMH as the propellent and the final is CUS like in GSLV with the fuel being LOX oxidiser and LH2.

In essence all three stages+ booter between the Long March 3 series and the GSLV produce similar kind of thrust with the chinese one having slighly higher second stage thrust impulse. THE MAJOR difference in payload wieght is because of the additional first solid stage weight leading to lesser capacity in GSLV and also the chinese rocket seems to be having two Cryogenic Upper Stage motors in the third stage leafing to more final impulse..

Anybody having further points to add..I am not sure beyond this..

Thank russia for the first cryogenic engine, even when they were severely criticized
For it.

GSAT 14 Mission Profile »
After its injection into
Geosynchronous Transfer Orbit (GTO) by GSLV D5, ISRO's Master Control Facility (MCF) at Hassan
takes control of GSAT 14 and performs the initial orbit raising manoeuvres in three steps, firing the satellite's Liquid Apogee Motor (LAM), finally placing it in the circular Geostationary Orbit.
Following this, the deployment of the antennae and three axis stabilisation of the satellite will be
performed. GSAT 14 will be
positioned at 74 deg East
longitude and co-located with INSAT 3C, INSAT 4CR and KALPANA 1 satellites. The 12 communication transponders onboard GSAT 14 will further augment the capacity in the INSAT / GSAT system. (ISRO)

"I am really happy... Now the sky is the limit for India. We should now have an overall plan and am sure scientists are working on it as this cryogenic engine is the best of its kind," said S. Nambinarayanan.

.

how can your cryogenic engine become a best of its kind when we have launching our engine for the first time successfully and other nations are having this type of engine from ages and also upgrading and developing new technologies.

Perhaps you should go through the previous few pages. Best of its kind does not mean whether it is launched the first or tenth time...its about the technology under the hood....

Congrats to ISRO.

I hear this rocket had cameras on board. I would like to see those videos as well.

one of our "friends" denies us technology and the other actually gives

Re: India's GSLV successfully launched GSAT-14

The successful launch of India's heavier rocket - the geosynchronous satellite launch vehicle-D5 (GSLV-D5) - Sunday not only means the indigenous cryogenic engine is performing well but also would pave way for sizeable savings, the space agency's chief said Saturday.

"When GSLV-D5 succeeds in its mission Sunday, it means the Indian cryogenic stage/engine is performing well. It is a culmination of major indigenous technology development," Indian Space Research Organisation (ISRO) chairman K.Radhakrishnan.

In addition, the mission's success would not only pave way for ISRO to save launch costs paid to foreign space agencies but also to launch more communication satellites augmenting the transponder capacity to earn more revenue, he added.

Radhakrishnan said the country pays around $85-90 million or around Rs.500 crore as launch fee for sending up a 3.5 tonne communication satellites whereas the GSLV rocket costs around Rs.220 crore and the GSAT-14 that would go up Sunday evening costs around Rs.145 crore.

The ISRO can send smaller communication satellites - weighing around two tonnes - till such time it gets ready an advanced GSLV variant that can lug satellites weighing around four tonnes.

While that is for the future, Radhakrishnan said ISRO has lined up several satellite launches for the current GSLV rocket version.

"We will be launching satellites GSAT-6, 7A, 9 using GSLV. We will also be using this rocket for our second Chandrayaan mission and for the launch of GISAT," he said.

According to him, another communication satellite GSAT-15 will be launched using the Ariane rocket.

Other than the flight testing of cryogenic engine, 2014 will be an important year for ISRO.

Radhakrishnan noted that in September, the Mars Orbiter will be injected into the Mars orbit while the test flight of GSLV-Mark III version will also include a crew module for characterisation of re-entry from the space.

"The GSLV-Mark III experimental mission will be in April this year. The rocket will have a passive cryogenic stage/engine. The main purpose of the mission is to study the aerodynamics and stability of the rocket," he said.

He said the cryogenic engine for the next GSLV version will take around three years for being flight ready.

According to him, the next fiscal (April 2014-March 2015) would see ISRO launching three IRNSS (Indian Regional Navigational Satellite System) satellites taking the total to four and be ready for usage.

He said ISRO will also launch French satellite SPOT-7 along with four small satellites using its other rocket Polar Satellite Launch Vehicle (PSLV).

Radhakrishnan said ISRO plans to induct around 96 transponders (receivers and transmitters of signals),next fiscal. Currently it has 195 transponders.

Queried about the Mars Orbiter that was launched last year, he said the satellite health is good and it is around 8.5 million kilometer from earth.

"The next orbit maneuver (course correction) will be in April," he said.

Can India use this engine to develop long range ICBM's?

Can India use this engine to develop long range ICBM's?

ICBM technology already proven using the agni 5 tech. We just need to stratergic requirement to push it to testing and production. Also in the Mars mission too we saw hints of it during the looong coasting phase of the upper stage when it was nearing the end of IOR and into the pacific.

LOL!! HAL now wants a share of the reflected glory..Not a bad thing but shows the truth of the adage -- that victory has many friend while failure has....

Contributed significantly to GSLV D5 success: HAL

Perhaps somebody can suggest to them to get the GTRE to otusource some help for kaveri from the ISRO...
