The static test of first stage solid motor (SS1) of ISRO's Small Satellite Launch Vehicle (SSLV) -- a new-generation compact rocket -- was not successful, according to sources in ISRO. "Oscillation was noticed after 60 seconds into the test and nozzle was blown out near the bucket flange where it's attached with the motor at around 95 seconds", sources in the Bengaluru-headquartered space agency said.
It was supposed to be tested for a total duration of about 110 seconds, officials said.
New motor has to be static tested on the ground to prove its performance. If it is successful, one more of the same configuration is tested again for acceptance.If both are successful, no more ground test is required and third motor of the same configuration will be accepted for flight", an ISRO official said.
It is a three-stage all solid vehicle with a capability to launch up to 500 kg satellite mass into 500 km low earth orbit (LEO) and 300 kg to Sun Synchronous Orbit (SSO).
