Thanks for clarification ...I really didn't know it ....I always thought that it's just an alphabetical order ...



Hi guynextdoor ,
Don't be so mean ...appreciate the fine gesture of our friend !

I THANKED him before I put that post dude...anyway it was more of a humor post than a scarcastic one!

I know ..I said in humorous note too ! Our Taiwanese friend should not feel otherwise that's why I coaxed you ...

Inclusion of video imaging system. Hope they show the video on the telecast.

MAJESTIC!!!!!!!

wow!! Truely Majestic!!!

 

[Indo-guy]

wow!! Truely Majestic!!!

Correction , video imaging system is installed at third stage ...It is meant for inspection,monitoring and analysis puprpose ( in case of failure )

This video imaging system ...has nothing to do with launch telecast or so ....

And yes GSLV looks majestic !!!
Great pic ...

Thats what the role of a video imaging system is on all Launch vehicles. We are just hoping that like others (NASA, SpaceX etc), ISRO also includes some of the imaging system output in the telecast.

They do include some footage about inputs about launch progress...if you have seen some of the previous launches .

But regarding video imaging ...I think it's being used first time in such mission.

Yes this is the first time and Thats why I hope to see the video of our cryogenic baby in action live

ISRO rocket launch on Monday with indigenous cryogenic engine

In a month marked by key advances in indigenously-developed technology, India’s space agency will also test its mettle with a crucial rocket, powered by a cryogenic engine built in the country, slated to blast off Monday. The countdown for the flight of the heavy geosynchronous satellite launch vehicle (GSLV) is set to begin Sunday evening, Indian space agency officials said. According to Indian Space Research Organisation (ISRO), the 29 hour countdown would start at 11.50 a.m. Sunday and the rocket is expected to blast off at 4.50 p.m. Monday from India’s rocket port Sriharikota in Andhra Pradesh, around 80 km from here.

This month has already seen key advances. As the country celebrated its 67th Independence Day, the month saw activation of the indigenously built small reactor to power submarine INS Arihant, the launch of the indigenously-built aircraft carrier INS Vikrant while a unit of Kudankulam Nuclear Power Project (KNPP) is expected to be connected to the grid month end. One event that created a shadow was the loss of Indian naval submarine INS Sindhurakshak.

Now eyes are on the ISRO to see whether the GSLV, powered by its own crucial cryogenic engine would successfully deliver its baby-communication satellite – the 1,982 kg GSAT-14 – into outer space. “After two GSLV failures, ISRO has to prove itself at the earliest possible. There is always a pressure on that count,” a senior ISRO official, who did not want to be named, told IANS. This will be the first mission of GSLV during the last three years after two such rockets failed in 2010.

One of the GSLV rockets flew with Indian cryogenic engine and the other one with a Russian engine. The GSLV is a three stage/engine rocket. The first stage is fired with solid fuel, the second is the liquid fuel and the third is the cryogenic engine. The successful flight of this rocket is crucial for India as it will be the first step towards building rockets that can carry heavier payloads, up to four tons.

According to ISRO, several design changes have been incorporated in the Monday’s rocket for a safe flight. Design changes were made in the lower shroud/cover that protect the cryogenic engine during the atmospheric flight; wire tunnel of the cryogenic stage to withstand larger forces during the flight; and the revised aerodynamic characterisation of the entire rocket. Others included video imaging of lower shroud movement during various flight phases; fuel booster in cryogenic engine; and ignition sequence of the cryogenic engine.

ISRO said indigenisation of many critical systems including liquid hydrogen propellant acquisition system (to prevent possibility of outside contamination) was achieved. It is going to be a tense 17 minutes for the ISRO scientists Monday after the 49.13 metre tall rocket weighing 414.75 ton blasts off at 4.50 p.m. till the GSLV rocket safely delivers GSAT-14 to augment the Indian transponder – receivers and transmitters of signals – capacity. ISRO is planning to launch an upgraded version of GSLV Mark III rocket next year with a dummy payload. The design payload capacity of GSLV Mark III is four tons. Meanwhile an ISRO official said the fuelling of the three stage/engine GSLV rocket’s four strap-on motors and the second stage with liquid fuel will be completed by Aug 19 morning while the first stage core engine is powered by solid fuel. The process of fuelling the cryogenic engine will begin around 10 hours prior to the launch.

^^^ Its important to call out that this is India's first indigenous cryogenic engine. India has successfully launched GSLV missiles but this is the first with indigenous cryogenic engine. Hope India is successful this time.

Nope the earlier launch with the Indigenous cryogenic engine failed. Ot was on the GSLV D3 in April This year.

We might see the operation of new Acoustic suppression system in this mission.

What is it actually..??

 

[satishkumarcsc]

What is it actually..??

Reducing the noise at the time of launch thus reducing the violent vibrations that sometimes lead to failure of the rocket.

The vibrations would be a problem if the launch vehicle sits still on the launch platform. Considering that it moves up almost as soon as the gasses start egressing, I don't see how the acoustic supressor would help in that matter.
I thought it was for the us humans to reduce the impact on ears.

It sits on the platform for a few seconds till the thrust required is attained. And also take into account the gasses expanding 10,000 times more when the rocket is ignited.
