INTRODUCTION

In support of the Army-wide modernization program, the Manufac- turing Technology Division of the U.S. Army Armament Research and Development Command (ARRADCOM) developed design standards for structures required to withstand the effects of an explosion. The employ- ment of these standards--in a safe and cost effective manner--requires that the airblast characteristics of the energetic materials used by the Army be empirically determined. Since the air blast capabilities of Benite propellant are not available in the current literature, a TNT equivalency test program was initiated under MMT project 5774285.

The objective of the test program was to determine the maximum airblast output from the detonation of Benite propellant in terms of peak pressure and positive impulse compared to known characteristics of a hemispherical surface burst of TNT.

TEST PROGRAM

Material

Benite propellant conforming to Military Specification MIL-B- 45451B, 23 February 1962, was used throughout the testing. Specific- ally, the test material consisted of extruded Benite strands (0.203 cm in diameter) from Radford Army Ammunition Plant, Lots RAD 1-132 (25.4 cm long) and RAD 77 F001-061 (45.8 cm long). The Benite was composed of:

40% nitrocellulose 44.3% potassium nitrate 6.3% sulfur 9.4% charcoal 0.5% ethyl centralite (added)

Test Plan

A survey of a prototype explosive-manufacturing plant revealed that the production of solvent-wet Benite presents little danger of an explosive reaction during the manufacturing process, and does not constitute a potentially hazardous situation. On the other hand, the probability of a detonation during shipment and storage of Benite and/or Benite-loaded munitions exceeds the minimum acceptable risk. Consequently, a test plan was formulated (table 1), and loaded

shipping containers and mass storage (packout) areas were selected for TNT equivalency testing. Airblast output of the following test configurations was measured:

1. Simulated shipping container--an orthorhombic container (fig. la) made of wood and fiberboard, filled with 10.43 kg of Benite propellant.

2. Simulated packout area--an orthorhombic container (fig- lb) filled with 41.8 kg of Benite propellant.

A conical-chaped booster charge of Composition C-4 high explosive was buried in the center of each container, with the apex pro- truding above or flush with the top surface (fig. 1). The booster was detonated with an engineers' special J-2 blasting cap inserted at the center of the cone's apex. The booster weights varied from 2% to 17% of the charge weight.

The test charge for each configuration was placed on a 0.61 by 0.61 by 0.0064-meter-thick 1010 carbon steel witness plate in the center of the test area (fig. 2). The area was regraded after each test and measurement of the crater diameter.

Instrumentation

Twelve Susquehanna Instruments Model ST-2, ST-4 side-on blast transducers were mounted in steel plates that were buried so that the sensor was at ground level in two arrays within the test area (fig. 3). Distances between transducers and charges (table 2) were calculated to correspond to scale distances of 1.19, 2.72, 3.57, 4.37, 7.15, and 15.87 meter/kg1'3. The transducers were individually calibrated prior to each test series with pressure pulses from a standard solenoid- actuated air pressure calibration fixture, adjusted to correspond to expected blast pressure on an assumed TNT equivalency of 100%. This calibration was verified initially by measuring free-field blast pressures from a 11.34-kg bare hemispherical charge. C-4 signal line continuity and channelization were checked prior to each test.

Each transducer was connected to an underground coaxial system which led to the instrumentation trailer, approximately 175 meters from the test area. In order to capture the complete pressure-time pulse, the recording instrumentation response was synchronized with the blast-wave arrival times. The biomation recorder (200 micro- second period) was connected to the three gages in each array closest to the blast source, while the pulse-code modulation (PCM) unit (0.315 millisecond period) was connected in parallel with the biomation recorder and to all of the gages. All test data were recorded on this dual system.

Photographic coverage was limited to one test of each configuration (fig. 3). Motion picture coverage included a Fastax camera operated at 500 frames per second (fps) and a Mitchell camera operated at 24 fps. Standard meteorological data were recorded for each test.

RESULTS

Data Analysis

Peak blast overpressure, time of arrival, and scaled positive- impulse information were obtained in direct analog form from the oscillograph records. After exclusion of poor results that could be attributed to instrumentation malfunction, impingement of fragments on the transducer elements or improper calibration, average values for peak pressure and scaled positive impulse were calculated for each weight and scaled distance.

The average peak pressures were compared directly with the standard reference curve for a hemispherical TNT surface blast. These comparisons were used to derive TNT pressure equivalency (Ep) as a percentage by weight based on equivalent side-on blast pressure at equal distances from charge:

h = 100 WeightTNT

Weight Benite Constant pressure and radial distance

The scaled positive impulses were also directly compared with the standard reference curve for a hemispherical TNT surface blast to derive TNT impulse equivalency (Ej) as a percentage by weight based on equivalent positive impulse at the same radial distance from the charge:

100 WeightTNT

WeightD .^ 6 Benite Constant positive impulse and radial distance

The mathematical basis for pressure and impulse equivalencies are contained in reference 1. This technique provides a means of relating the peak pressure and impulse data from the detonation of

the test samples to that of a hemispherical surface burst of TNT while extracting the booster contribution.

Discussion

At the outset of testing, a 2% (by weight) Comp C-4 booster was chosen as the source of initiation. However, posttest investigation of the unsheared steel witness plate and the unburnt Benite strands in the vicinity of the test pad was not indicative of complete mass detonation. Data analysis substantiated this assumption for none of the computed equivalencies exceeded 35%. Since complete detonation was not achieved, the booster weight was incrementally increased to 17%. The magnitude and completeness of the explosive reaction did not significantly increase (less than 65% equivalency in all tests) even with the inordinately high percentage (17%) booster.

The size of the booster was not increased and the cumulative mean equivalency was reported for the following reasons:

1. The blast output of the booster would exceed that of the test sample.

2. Testing would be representative of a highly unlikely initiation condition in the munitions plant.

3. The percentage booster would not be comparable with any of the previous equivalency test programs.

Test Results

Benite propellant was detonated in full-scale and scaled-up configurations representative of both single and mass storage of orthorhorabic shipping containers. Blast output parameters were measured and TNT equivalency was computed on the basis of comparison with TNT hemispherical surface bursts. Complete detonation of the Benite propellant was not achieved by boostering with Comp C-4 (up to 17% by weight). Pressure and impulse equivalencies were found to be less than 65% in all tests. The results of these tests are presented in table 3.

The TNT pressure and impulse standards for a hemispherical surface burst are shown in figures 4 and 5 in both metric and English units. Pressure and scaled positive data for Benite are summarized by test configuration in tables 4 and 5 and figures 6 through 9. Percent TNT equivalencies for both test configurations are shown in figures 10 through 13 as functions of scaled distance.

Figures 14 through 19 are selected pretest and posttest photo- graphs. Data sheets for all tests with pertinent measures parameters are given in the appendix. (The test numbers shown are for local reference only and provide access to original range data files.)

CONCLUSIONS

1. The pressure and impulse TNT equivalency of stranded Benite in the two orthorhombic configurations tested varies with scaled distance and is less than 65%.

2. The blast output from the Benite test samples increased marginally with the size of the booster to a point where further testing was not cost effective. Complete mass detonation was not achieved even with a 17% Comp C-4 booster.

3. The orientation of the Benite strands within the shipping container (i.e., horizontal or vertical) had no discernible effect on the resulting blast output.

RECOMMENDATIONS

The TNT equivalency values determined from this test series should be used in the structural design of protective facilities con- taining Benite propellant. However, since cube-root scaling was not demonstrated, it is recommended that any extrapolation from the test configurations and constraints be verified by additional testing.
