Abstract:
The present invention relates to a system and method for controlling the buoyancy of an underwater submersible. Accordingly, a novel buoyancy control system for controlling the buoyancy of an underwater submersible, comprising of a housing configured to enclose a controller and a power source. A swim bladder having a flexible membrane covering an upper end, attached to an upper portion of said housing through a lower end, characterized in that a heater is positioned inside the swim bladder containing a fluid. The controller is configured to actuate in which the power source supplies power to the heater to cause liquid to vapour phase transition of the fluid. The submersible is configured to ascend on heating during which the phase transition is from fluid phase to vapour phase, and to descend on cooling during which the phase transition is from vapour phase to fluid phase, such that by varying the power supplied to the heater the buoyancy of an underwater submersible is controlled

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
