‘Noiseless technology tackles gun-running’

VISAKHAPATNAM: Defence Research and Development Organisation Chief Controller A. Sivathanu Pillai on Tuesday called for a national mission on acoustics.

He was delivering the keynote address at the two-day national symposium on acoustics, which was earlier inaugurated by Vice-Admiral Nirmal Verma, Flag Officer Commanding-in-Chief, Eastern Naval Command.

About 200 delegates attended the seminar conducted jointly by Naval Science and Technological Laboratory and Acoustical Society of India. The seminar was preceded by a workshop on quieter technologies.

The deliberations were focused on acoustics, a multi-disciplinary subject, which encompasses many branches of engineering, basic sciences, physiology, psychology, medical/clinical, architectural and military/defence applications.

Stating that DRDO contribution for research on acoustics was immense, Dr. Pillai spoke on evolution of warfare and how acoustics donned a pivotal role in supersonic cruise missiles with precision strike, space-based surveillance including coastal protection, kinetic engineering weapons, cyber warfare and unmanned underwater system.

Dr. Pillai, who is also the CEO and Managing Director of BrahMos supersonic missiles programme, said acoustics had several applications for marine warfare with India having a 7,600-km coastline and 2.5 million square km of Exclusive Economic Zone.

He said noiseless technologies would also come handy in tackling issues like pirates, narco-terrorism, gun-running and maritime pollution and recalled the contribution of dedicated satellite surveillance, supersonic cruise missiles, submarine weaponry like torpedoes with quieter technologies, signature class and pump-jet propulsions.

Nano tech

Touching upon the importance of nano technology, he said India should have strategic superiority through acoustics and underlined the need for making advances in signature shipping and stealth technology. He said strategic superiority could be achieved through autonomous underwater vehicles, naval platforms, sea-fed arrays, sensor networks and acoustic stealth studies.

Describing how hydrodynamic studies were undertaken at IIT, Madras and Kharagpur, he said efforts were also on for cost-effective tsunami early warning system.

Vice-Admiral Verma in his address said acoustics had an important role in navy right from naval band to warships. Underwater acoustics was crucial in modern warfare, he said adding a seamless network and acoustic signature management would always escape detection of a ship.

AU Vice-Chancellor B. Satyanarayana, Acoustic Foundation for Education and Charitable Trust H.S. Paul, DRDO Director V. Bhujanga Rao and Assistant Director N.S. Naidu spoke.
