The Blast Load Generator is under development at the U.S. Army Engineers Waterways Experimental Station at Vicksburg, Mississippi. It will be used to simulate blast loading for experimental effects studies. Propellant burning inside cylindrical perforated tubes is used to pressurize the Blast Load Generator. Picatinny Arsenal analog personnel were requested to simulate the operation, in order to arrive at the correct propellant charge for generation of given required pressures. Results obtained with a preliminary analog simulation setup gave an approximate picture of the Blast Load Generator. It was established that the over-pressure can be controlled by the vent area, the amount of propellant, and the propellant web. However, since the analog setup is still in its initial stages, several important items must be determined before accurate design of the charges can be undertaken. For example, the thermal coefficients and the effective surface area for heat transfer must be determined. Hence, the results presented in this report can be seen only as approximations and should be used only to indicate trends and guide future tests. (Author).

The report describes the development of three types of on-structure stress (OSS) gages (the IF and FS soil-pressure gages and the M-1 airblast gage) based upon the load column principle. The OSS gage design is based upon the assumption (backed by theory and experiment) that if the gage is made much stiffer than the soil, the over-registration of the gage approaches a constant value. A brief discussion of some of the unique problems of measurement of soil pressures is presented. Six OSS gages (four IF, one FS, and one M-1) were statically tested and evaluated with respect to linearity, hysteresis, resolution, thermal sensitivity, and strain sensitivity. Dynamic tests were performed in a laboratory shock tube and blast load simulator facilities. The OSS gages are concluded to be adequate for soil-pressure measurements on certain types of rigid structures and for airblast measurements, even in explosive atmospheres. They successfully measured dynamic gas pressure up to 5,000 psi in the firing tubes of the laboratory blast simulator device. Additional research is recommended to evaluate the gage performance more completely in static and dynamic soil tests. A range of soil types from coarse dry sand to moist fat clays should be investigated. Future research on gages for measuring soil pressures on structures should be concentrated on development of small gages for use with models and thin-walled structures. (Author).

The primary objective of this study was to determine the pressure-time signatures that are produced in the Small Blast Load Generator (SBLG) bonnet and firing tube chamber by detonating a charge of M-9 propellant. A secondary objective was to obtain information which would contribute to a better understanding of the heat-absorbing characteristics of the firing tubes and bonnet. Four dynamic shots ranging from 83 to 199 psi were made in the SBLG using M-9 propellant and detonating cord. Pressure was measured in the bonnet (free-air overpressure) and within one of the firing tubes, and temperature was measured on the inside and outside surfaces of the bonnet, on the outside surface of one of the firing tubes, and in the gas within the bonnet. The pressure-time histories in the generator bonnet were approximately the same when either the M-9 propellant base charge or detonating cord was used as the charge. The relation of peak pressure in the firing tubes to peak pressure in the bonnet was linear. The temperature measurements on and in the bonnet and firing tube were inconclusive because the gages were damaged during the blast. However, the results obtained indicated that the temperature of the generator inner surface changes only slightly, no more than 5 F at 3 sec after detonation. The temperature of the gases within the bonnet reaches approximately 2000 F. (Author).
