The Blast Simulator project involves the development of an apparatus able to reproduce the effects of a blast pressure wave on large scale structural components (such as columns, walls, etc.) with the objective to improve their strength in these severe loading situations. This technical report presents the setting up and the performance assessment of the prototype blast actuator developed at the JRC. The first preliminary tests performed have been described and evaluated. Satisfactory results have been obtained with respect to impacting masses and velocities and with the finally obtained pressure values.

The Blast Simulator project involves the development of an apparatus able to reproduce the effects of a blast pressure wave on large scale structural components (such as columns, walls, etc.) with the objective to improve their strength in these severe loading situations. After a series of preliminary tests to assess the performance of the blast actuator for what concerns the energy capability, this technical report presents some results related to a test campaign on two full scale structural components, specifically two reinforced concrete beams. With appropriate improvements made to the impactor, it has been possible to successfully bring the components to failure. A full suite of test parameters has also been recorded, valuable for guiding the numerical modelling. These experiments validate the potentiality of this kind of equipment to reproduce in a laboratory the effects of a blast explosion on full scale structural elements without using explosives. Further tests with the same experimental setup and with a new testing rig based on a more innovative technology (electrical linear motor) will be conducted in 2015 in the context of BUILTCIP project.

The Electrical Blast Simulator (e-BLAST) activity involves the development of an apparatus capable of reproducing the effects of a blast pressure wave on large-scale structural components (such as columns, walls, etc.) with the objective of improving their strength in such severe loading situations. The work relates to the BUILT-CIP project which deals with the protection and resilience of the built environment (critical buildings, transportation and energy infrastructure etc.) under catastrophic events such as blast and impacts. The e-BLAST facility has been conceived and designed with the expertise acquired in the previous project "Blast Simulation Technology Development", supported through an Administrative Arrangement by DG HOME. Differently from the prototype developed in that project, the e-BLAST exploits a recent technology that appears to be very promising in this particular research field. Specifically, three synchronous electrical linear motors have been adopted for accelerating the impacting masses. This choice has led to develop a more effective, versatile and low-cost facility. The report presents in detail the facility design, its components and their assembly, and a series of preliminary tests carried out in the ELSA laboratory in order to assess the performance of the e-BLAST. Finally, a brief description of further developments and feasible large-scale structural tests, planned to be performed with the new facility, are discussed.

The muzzle blast simulator (MBS) project was initiated in 1984 with the objective of providing a sound generator for the assessment of the performance of hearing protection devices. Other potential applications of the MBS include the study of the subjective and physiological response to blast waves and its use as a training tool. This report presents findings of a feasibility study undertaken to determine the hardware and software requirements for the successful completion of the original MBS design work. It first reviews the context of the MBS project, then assesses its current status and its critical success factors and issues. This is followed by system requirements of the new MBS system, such as system data, system functions, user interface, and hardware. The next two chapters address the important software and hardware issues such as languages, data base management systems, control and management functions, waveform processing functions, interfaces, and hardware components. Finally, the cost efficiency of the MBS project is discussed and implementation scenarios and cost benefits of the project are assessed.

This study defines the user requirements for a fuel-air explosive test facility for nuclear blast simulation. It details an experimental program and provides the design for an initial experimental fuel-air explosive facility with a capacity of 10,000 pounds of fuel which, by making use of its design as a basic cell, may be expanded to a full 1-KT nuclear blast simulation facility with a 200,000-pounds fuel capacity.

This study investigates the feasibility of using unconfined fuel-air explosions to simulate the balst effects of up to one kiloton nuclear explosions. The detailed theoretical physico-chemical calculations of this study along with experimental observations from other sources show the feasibility of such simulation. Substantial savings in the cost of nuclear blast simulation as well as improved predictability are indicated by using a fuel-air explosion in lieu of HE or Ammonium Nitrate-Fuel Oil (ANFO). Preliminary engineering and hydrodynamic calculations for a re-usable fuel-air explosion facility are presented along with recommendations for further engineering design developments in the several methods described which will achieve the desired fuel-air explosion.

The object of this research program is to determine the most feasible means of obtaining a nuclear blast simulator which will reproduce the transient flow field associated with the 500 psig. overpressure range of large nuclear weapon detonations. The blast simulator is of the general purpose type and is characterized by a traveling shock wave followed by a flowing gas. The test section is of the order of 25 x 50 feet in section and contains, in addition to the gas flow region, a soil container or region in which air induced stress waves can be generated. Two concepts were considered the most feasible. One is the standard shock tube concept which consists of a long tube, closed at one end, in which explosives are distributed over a large region and detonated. The other is the space variable energy input shock tube concept which consists of a long tube, open at both ends, in which explosives are distributed in a non-uniform manner. The resulting detonation yields longitudinal pressure gradients which are similar to the wave forms of interest. Both of these concepts simulate the overpressure and dynamic pressure variation in the test section satisfactorily. Cost estimates for these two concepts were made for a variety of facility sizes and blast wave parameters. (Author).
