India should go in for collaboration at the international level for developing capabilities in High Energy Materials (HEM), B Bhattacharya, director, High Energy Materials Research Laboratory (HEMRL), said on Thursday.
Bhattacharya was addressing the 9th International Conference on High Energy Materials organised by the HEM Society of India (HEMSI) at Kovalam. He also stressed the need to bring down costs in the research and development of HEMs. India does business in HEMs to the tune of Rs 15,000 crore. About 75 per cent of the amount goes for importing, he said.
To avoid this, India should develop advanced technical skills in this area by starting centres of excellence in institutions such as the Indian Institutes of Technology (IIT), he said.
HEMs form an integral part of the space technology and the defence sectors.
Inaugurating the seminar, Dr S Ramakrishnan, director, Vikram Sarabhai Space Centre (VSSC), stressed the need for shifting to ‘green propellants’ for launch vehicles in the long run. He also called for extensive research in the field of HEMs.
Dr Manjit Singh, director, Terminal Ballistics Research Laboratory, stressed the need for adhering safety precautions while working in the field of HEMs.
There is a need to study the ways and means to dispose unusable materials, he said.
Delivering the HEMSI-M R Kurup lecture, M C Dathan, director, Liquid Propulsion Systems Centre (LPSC), stressed the need to further develop the solid-state fuel technology.
There are lots of advantages in using solid state fuels as they are cheaper, less complex and yet, highly reliable.
A suitable combination of solid, liquid and cryo fuels can effectively propel any complex rocket systems.
He also stressed on the need to use composites based rocket cases to reduce mass.
