Video: ISRO successfully tested world's third largest solid rocket booster

[Kinetic]

ISRO successfully tested world's third largest solid rocket booster S-200 for GSLV mk III. This is the second successful ground test of the booster.


S200 solid booster contains 200 tonnes of solid propellant in three segments. The motor measures 22 meter long and 3.2 meter in diameter. The design, development and successful realisation of S200 solid booster were a pure indigenous effort involving Vikram Sarabhai Space Centre, Thiruvananthapuram and Satish Shawan Space Centre (SDSC) at Sriharikota with the participation of Indian Industries.


You can see the thrust vectoring of the nozzle! The booster was fired for 130 seconds against actual requirements of 103 seconds.

Thanks kinetic bhai I think ISRO is the only PSU which is really making all the indians proud .
What about those cryogenic engines??
I just fail to understand that when can make bosters like these what is stoping us from making a Aircraft engine like Kaveri??

 

[pmukherjee]

Let's wait for the flight test.

Please someone answer my queries in my post #2
Butters ko ban kyon kar diya Mods??

Next flight of Indian cryogenic engine is mid next year. A much more powerful cryogenic engine C-25 for the GSLV mk III will undergo testing this year.

I just fail to understand that when can make bosters like these what is stoping us from making a Aircraft engine like Kaveri??

Kaveri is more complex than this and we already made Kaveri. It has undergone successful high altitude flight test in Russia. But IAF wants more powerful engine that it actually wanted in past. Very very few countries developed such FADEC engine. Russia with its decades of experience just recently developed a FADEC engine. Pls do not go after what some BS says. they said same about Arjun few years ago and now it is clear Arjun is the perfect beast not T-90S.

Just give ISO and DRDO one more year on Cryogenic engine and Kaveri. It will be a sccess story just like other projects. These attempts are our firsts.

Simple answer - Complexity!!

Rockets are propelled by the ignition of a highly flammable fluid, typically H2O2 with additional O2 tanks to supply oxygen at higher altitudes. Their thrust is generated exclusively through the resulting combustion of the accelerant. Very simple by design and have little or no moving parts.

Jets, or turbine engines are more complex, although simpler than an automotive engine. Within the engine there is a combustion hot section where jet fuel is ignited. Simply put, this results in the spinning of the turbine, which takes in air at the frontal section, compresses a large amount near the combustion chamber, then feeding it through the combustion chamber where it assists in keeping the fuel ignited, expanding the mass of air. This rapid expansion through the exhaust is what creates a massive amount of air/exhaust gasses, moving at hundreds of miles an hour creating thrust and propelling the aircraft forward.

It is a lot more complicated, but this will have to do for now!

Cheers!

Because a turbofan engine is a lot more complex than a solid rocket motor. In case of a rocket motor, you need capabilities to develop large motor casings, propellant and nozzle with control and actuation systems. In case of a turbofan, the biggest challenge is to develop materials which can withstand very high temperatures for extended engine life (typically 1000's of hours). In case of a rocket motor, it is just a single flight lasting minutes.

edit: Heck I already see answers posted. Sorry about that!

Arre bhai pehle ek bhi answer nahi kar raha tha abb sabhi ke sabhi mere pichhe padd gaye Thank you guys for giving my post so much attention.

Umm,are you trying to state that rocket science is an easy skill to master? Many countries and companies can construct a jet engine but to put a rocket on the trajectory to the moon and successfully land a probe on it's surface or launch satellites in perfect geosynchronous orbits? Not as easy as you've written it off my friend.

There's a reason behind the evolution of the phrase "It ain't rocket science" precisely because of it's numerous complexities.

Agreed but the design may be simple but implementation may not, specially when it is very large size... 200 ton.

These type of videos are so rare.

Good News...
What's the status of the Indian cryogenic engine ?

ISRO successfully tests Asia's largest rocket booster

The Indian Space Research Organisation (ISRO) successfully carried out the second test of the S-200 rocket booster early this month. The massive booster will form the strap-on stage for the Geosynchronous Satellite Launch Vehicle Mark-III's (GSLV Mk-III) maiden flight scheduled for 2012-13.

The S-200 booster. Image: ISROThe strap-on S-200 rocket booster is stated to be the biggest in Asia and the third largest in the world, smaller than the ones that put NASA's shuttle into space and Arianespace's Ariane-5 rocket.

The strap-on stage provides an initial boost to the rocket as vehicle load is the heaviest at the take-off stage and the force of gravity is the maximum.

The GSLV Mk-III, which is now in an advanced stage of development, will have two strap-on boosters fixed to the rocket. The huge rocket will take communication satellites of the four tonnes class into orbit.

The current version of the GSLV can orbit communication satellites of two tonnes weight.

The GSLV Mk-III's operationalization will drastically reduce ISRO's dependence on Arianespace to orbit its four-ton class of communication satellites.
