Extensive field testing is necessary for the design of blast and impact-resistant construction. This paper presents the design and development of a novel indigenous Blast and Heavy Impact Simulating Mechanism (BHISM), which can be used for full-scale blast experiments on structures without using explosive materials and their associated fireball. The design procedure involves numerical validation of existing test results of the blast simulator and further optimization of the performance using concepts of CFD simulation of the initial test configuration of the proposed simulator. The full design, fabrication, and installation of the indigenously developed BHISM is performed. The blast profile was obtained from the modelled shock tube and compared with the Friedlander blast profile. The suitability of BHISM for performing the experiments was checked by validating the numerical simulation results of the BHISM shock tube with the experiments performed on the already existing UNL shock tube and comparing the pressure-time and impulse-time curves. The novelty of the developed facility lies in the fact that a full-scale testing facility for Blast and Impact has been created without the use of explosives and meeting the test requirements of various applications.
