Engineers in India have decided to completely replace the leaking second stage engine of the GSLV rocket whose launch was scrubbed last week.
The GSLV is a three-stage launch vehicle with four strap-on motors hugging the first stage. The first stage is powered by solid fuel while the four strap-on motors and the second stage are powered by liquid fuel. The third is the cryogenic engine powered by liquid hydrogen and liquid oxygen.
“At the rocket assembly building, the satellite, cryogenic engine and the second stage have been destacked. It has been decided to shift the second stage to Mahendragiri for detailed inspection and study,” the ISRO official told IANS. He said ISRO has also decided to start assembling another engine so that the GSLV could fly at the earliest. Queried about the time-frame for the GSLV’s flight, he said: “It is not possible to give a time-frame for the GSLV’s flight now.”
