Mumbai: There was no major design flaw in the
ISRO's Geostationary Satellite Launch Vehicle, which crashed
seconds after take-off on December 25 last year, said a fact-
"We found that there is no major design flaw in GSLV-F06.
However, the fact-finding on the failure is continued, and
mostly within next few weeks we should be able to draw a
conclusion," G Madhavan Nair, chairman of the GSLV-F06
Analysis Committee, said here Saturday.
The failure could be due to severe "environment"
conditions, he said without elaborating.
However, the committee will be able to draw final
conclusion within next few weeks, Nair said.
GSLV-F06 (with GSAT-5P satellite on board) was normal
till 47.5 seconds from the lift-off. The events leading to the
failure started at 47.8 seconds. Soon, the vehicle started
developing larger errors in its orientation, leading to the
crash, he said.
The committee has collected evidence from photographs,
telemetry data and the previous flight data, Nair said.
"The first-level report has been submitted where we have
clearly established which type of connectors got de-mated in
the flight. Now we have to establish how they came apart. For
that, additional tests are required," he said.
