India achieves self-reliance in GSLV technology
Bangalore, Nov 16: India`s efforts to acquire self-sufficiency in Geosynchronous satellite launch vehicle technology has received a major boost with the "successful" testing of an indigenously developed cryogenic engine.
The test of the indigenously developed cryogenic engine carried out at the liquid propulsion systems centre (LPSC) at Mahendragiri in Tamil Nadu yesterday was successful, Indian Space Research Organisation Chairman G Madhavan Nair said.
"With this successful test, India`s GSLV programme has become absolutely self-reliant," Nair said over phone from Thiruvanathapuram today.
"GSLV vehicle has become totally indigenous. GSLV was flying with Russian (cryogenic) stage, (so far). With this indigenous stage, we are on our own," he said.
India so far depended on Russia for providing cryogenic engines for its GSLV vehicles. LPSC is the lead centre for development of Cryogenic Upper Stage (CUS).
The cryogenic engine is required to launch the geosynchronous satellites that are used in communications. This technology was so far confined to Russia, Europe and the US which used it to launch global commercial satellites.
Nair said the flight stage is getting ready for use in the next mission of GSLV (GSLV-D3) next year. "Flight stage is already under preparation at Mahendragiri. Things are progressing well," he said.
Terming the "successful test" as a significant milestone in India`s space programme, Nair said the country now has a mature technology in cryogenic.
"Concerted efforts (for this achievement) were there in the last ten years. In between, there were problems and failures....That`s a learning curve. With this test, today we have a mature technology in cryogenic."
In the past, GSLV was flown with the stage supplied by Moscow.
"We have four of them (flown with Russian stage). Two more (of Russian stage) are in our stock", Nair said.
Summing up the feelings of the space engineers and scientists over the feat, he said: "they are extremely jubilant, and confident to face future challenges of GSLV-MK III equally well".
The indigenous CUS is powered by a regeneratively cooled cryogenic engine, which works on staged combustion cycle developing a thrust of 69.5 kn in vacuum.
Apart from the complexities in the fabrication of stage tanks, structures, engine and its sub-systems and control component, CUS employs materials such as aluminium, titanium, nickel and their Alloys, bi-metallic materials and polymides, according to Bangalore-headquartered ISRO.
