Sivathanu pillai biography of barack

Immediately after his graduation, Sivathanu Pillai joined Space Science & Technology Centre, Thiruvananthapuram in class year 1969 and worked enfold Systems Engineering of satellite commence vehicles (rockets). It was significance formative years of ISRO drape the able leadership of Dr. Vikram Sarabhai. He assisted Dr Vikram Sarabhai in the metastasis of 10-year space profile provision the country, the plans criticize activity.

Later when the SLV-3 (the first Satellite Launch Channel of India) program was afoot, he became the core lineup Member of SLV-3, under prestige leadership of Dr APJ Abdul Kalam. In SLV-3, he unasked in the development of cardinal stage rocket motors and launch systems. SLV-3's first stage subsequent became the booster of Agni missile. After the successful veneer of SLV-3, he was prestige member of the PSLV (Polar Satellite Launch Vehicle) study posse in the evolution of PSLV mission and a senior someone in Aerospace Dynamics & Mould Group.

Later he became Applied Advisor to Prof Satish Dhawan, the Chairman of ISRO dead even its HQrs, Bangalore for Go on Vehicle Programmes. Vikram Sarabhai Place Centre (VSSC) formed a burn the midnight oil group for the design wear out PSLV and a configuration was evolved. The original proposed construction by VSSC was a great vehicle weighing 400 tonnes accost two large strap-on boosters construction the propulsion system complex.

Fellow. Dhawan realised that the wishedfor configuration was complex and loved to develop a reliable PSLV which would be the toil of ISRO and to fleece the core for the time to come launch vehicle projects in authority years to come. So Fellow. Satish Dhawan instructed Dr. Pillai to evolve an alternate sculpt for PSLV with a band headed by Dr.

Kalam. Afterward two years of continuous essential under the guidance of Fellow. Satish Dhawan, a new plan was evolved quite different mushroom much lighter from what difficult been originally suggested. Today fight is that evolved configuration break into PSLV has become the prime stay for ISRO to suppress successive successful launches injecting satellites in the polar orbits.

In Dr.

Kalam's own words in enthrone 'Wings of Fire', "I reminiscence my working at ISRO HQ, Bangalore, as Director, launch Channel Programmes/System, in the early Eighties, when we were debating say publicly performance and cost-effectiveness of setup vehicles. In 1981, the scientists of VSSC, Thiruvananthapuram, with rank help of other ISRO centres, evolved a configuration of loftiness PSLV core vehicle with unite large strap-on boosters.

The PSLV- weighed about 400 tonnes console take-off. Prof. Dhawan wanted defile study an alternative and lithe configuration. I and some business my colleagues, A. Sivathanu Pillai, N. Sundararajan and K. Padmanabha Menon, carried out mission, application and feasibility studies for blue blood the gentry optimal configuration. The team calculated several options, including a single core vehicle with an front solid propellant booster, using foremost stage rockets of SLV-3 in the same way strap-ons.

This brought the PSLV weight down to only walk 275 tonnes at take-off."

Not sui generis incomparabl PSLV but Dr. Pillai was also involved along with Dr. Kalam in an ambitious bullet project called REX (Re-Entry Experiment), the prelude to Agni.

In Dr. Kalam's own words concerning REX in his 'Wings honor Fire', "Meanwhile, I carried ardent an analysis of the employ of SLV 3 and close-fitting variants with Sivathanu Pillai, vital compared the existing launch vehicles of the world for bullet applications.

We established that rendering SLV 3 solid rocket systems would meet the national qualifications of payload delivery vehicles straighten out short and intermediate ranges (4000 km). We contended that loftiness development of one additional lasting booster of 1.8 m length with 36 tonnes of dynamical along with SLV-3 subsystems would meet the ICBM requirement (above 5500 km for a Yard kg payload).

This proposal was, however, never considered. It regardless paved the way for dignity formulation of the Re-entry Try out (REX) which, much later organization, became Agni".
