This is India's one finger salute to all those technology denial regimes! (a very long finger, I must add!)

This is best picture man ... salute to isro...but not even a single pakistani media reported this...lol..

 

[Guli Danda]

Ohh..What a great month...Kudos ISRO! And DRDO Too

This is India's one finger salute to all those technology denial regimes! (a very long finger, I must add!)

As you can see my Indians, it's about to veer off course.

Death to the Yindus.

Wish! 1 day we see our own space shuttle launch ,that day be 1 of our most proudest moment as an Indian ..

Wait 2 years more, you will see our own space shuttle.

An Indian version of the space shuttle will be test-flown from the spaceport at Sriharikota in a year’s time. The Reusable Launch Vehicle-Technology Demonstrator (RLV-TD), as it is called, will be a combination rocket-aircraft: the aircraft with a winged body, which is the RLV, will sit vertically on the rocket.

The engineering model of the aircraft is ready at the Vikram Sarabhai Space Centre (VSSC) in Thiruvananthapuram. The first stage of the Satellite Launch Vehicle-3, flown in the early 1980s, will form the booster rocket. Weighing nine tonnes, it is called S-9.

After it takes off like a rocket, the booster will release the unmanned aircraft, which will go into space. At the end of the mission, the aircraft will land in the sea.

K. Radhakrishnan, Director, VSSC, said in an interview: “The next year we expect the prototype of the RLV-TD to be ready for flight-testing. This will be a milestone for ISRO.” The RLV “will open a new dimension in the launch vehicle technology and transportation system of ISRO.”

According to Dr. Radhakrishnan, ground testing of the booster rocket was done at Sriharikota in December 2008.

S. Ramakrishnan, Director (Projects), VSSC, explained how the rocket-aircraft would look: “The aircraft will stand over the rocket, nose-tip up, and its tail will be interfaced with the rocket. In other words, the entire RLV will stand vertically on top of the booster.” The engineering model of the prototype RLV was ready at the VSSC. “It will undergo various structural and load tests,” Mr. Ramakrishnan said.

The booster rocket will take the RLV to a specific altitude, release the RLV and fall into the sea. On re-entry into the earth’s atmosphere, the RLV will land in the sea, to be recovered.

“Re-entry, descent and recovery are the three issues which we are trying to understand,” Mr. Ramakrishnan said. But in the first trial-flight in 2010, the RLV will not be recovered from sea because it will not be cost-effective to do so. “But we will get the data on the re-entry, deceleration and return from the telemetry.”

There were several issues that the ISRO was trying to understand in the mission, Dr. Radhakrishnan said. These included the aerodynamics of the RLV, compared to the rocket, and the controllability of the vehicle. “The control system must be fast-acting. That is the basic challenge. The digital auto-pilot is important for the ascent phase and the descent phase.”

The third important challenge was the heat generated when the RLV re-entered the atmosphere. Dr. Radhakrishnan said: “You need to have hot structures [which can withstand the re-entry heat]… Today, we have a handle on the materials.”

The ISRO had a long way to go before it could build an operational RLV, he said. “This is the first TD towards that.”

woh din ab door nahin

btw.. can you pm me some decent places to get a PG in MUMBAI ? Navi mumbai/parel side would be fine also..

 

[HZR2011]

which one for pakistan and which one for China in RISAT 1 and 2?

 

[Bharthi]

For Agni , shaheen.
For PSLV, ?

 

[HZR2011]

Don't compare,you'll get infraction...
any way you can't compare India and pakistan... if you want the list goes very very long...

Why Indian posters are trolling here. Stupid are making me click this thread repeatedly and I am finding nothing knowledgeable but nonsense.

If whatever has to be said and needed to explained is already done then we should close this thread.

 

[GR!FF!N]

i was expecting more members from our neighbouring countries'll come here and will discuss about malnutrition and toilet problem..

though they didn't congratulate us,i thank them as they kept this thread clear.

@topic...

congrats ISRO..

Only 2 neighbours have graced this thread. One gave us "last warning" us not to be cocky and 1 said that the satellite is not indigenous but from Israel.
