• Development of Blast and Heavy Impact Simulating Mechanism for testing of products 

This project is part of my M. Tech. thesis where a blast load simulator is proposed for the testing of products under blast and impact loading. The blast load simulator is based on working principle of shock tube. A shock tube is device to create shock wave and elevate temperature of the driving gas (due to compression). A shock tube primarily consists of two chambers one at higher pressure and another is at lower pressure separated through a diaphragm or fast acting valve. The sufficient high pressure in the chamber will burst the diaphragm or open the fast acting value by virtue of this a shock wave will be generated. This shock wave is tuned to replicate blast wave arises due to explosion. The outcome of this project can highlighted as we got a patent grant, two conference publications and a journal publication (in the process).

• Design for use of Bamboo for Construction of Frangible Security Watch Tower at Barapani Airport, Shillong

The objects lies within designated safety area are required to be of minimal mass and height, mounted as low as possible to the ground, and to be mounted on frangible support structures.The major requirement of the proposed structure is frangibility and construction material should be bamboo and Sal wood (locally available construction material). Frangibility criteria is as follows: The resisted Impact force should be less than 45 kN and the absorbed Impact energy should be less than 15 kJ.

The frangibility has been achieved by making provisions of frangible connections.
