Each explosion is an occasion wealthy with knowledge. The problem is capturing that fleeting and violent info and rendering it sterile and helpful. Introduced in February, the US Military has a brand new software to raised seize the information from explosions, no less than from apply battlefields.
The trajectory of a bomb, the scattered patterns of its shrapnel, the peculiar form of its crater, even the holes it tears into the physique armor of an individual unlucky sufficient to be close by—each a part of the aftermath is info, if solely it may be recorded.
The novel software gathering this info is dubbed the Fragmentation Speedy Evaluation Generator utilizing Computed Tomography (FRAG-CT). It’s designed to streamline the gathering and evaluation of explosion knowledge, after which create helpful information for additional analysis, Lisa King-Schiappa, the lead of the staff that designed FRAG-CT for the Military’s Improvement Command, stated in a press release.
With higher, quicker evaluation, the Military can use that info to design new armor—and new bombs.
What’s FRAG-CT, and the way does it work?
The FRAG-CT technique creates an information file of the bombs’ “fragmentation traits,” in addition to an information file that can be utilized to design armor. As well as, it creates 3D information of every scanned fragment, which can be utilized in future evaluation. Most notably, the Military claims that this evaluation course of is 200 occasions quicker than gathering knowledge by hand, permitting evaluation time to shrink from “months to hours.”

Presently, classifying particles and shrapnel from intentionally set explosions is an enormous, labor-intensive course of.
A handbook from the Division of Protection Explosives Security Board known as “Procedures for the Assortment, Evaluation, and Interpretation of Explosion-Produced Particles” outlines precisely how a lot work goes into the normal hand-cataloging technique. This assortment consists of plotting out the place every bit of particles falls, weighing it, describing its origin, and extra.
It’s not but clear how, precisely, FRAG-CT will cut back the work of selecting up and weighing particular person particles items. The software program as described can soak up a number of knowledge inputs, suggesting it could work with sensors and cameras.
How will it assist the Military?
A greater understanding of explosions can enhance the design of each munitions and armor.
“Warhead growth is an iterative course of from design to prototype to testing and again to design,” Henry Hsieh, a mechanical engineer within the DEVCOM Armament Middle, stated within the press launch. “This course of is usually value prohibitive because of the time and labor required to gather and analyze huge quantities of information after a harmful warhead occasion. With this expertise in place, warhead builders can quickly and confidently design munitions tailored for our subsequent era of warfighters.”

Warhead design combines materials science with a powerful drive in direction of house effectivity. For a bomb to be helpful, it wants to stay inert till intentionally armed, it must trigger an explosion of a helpful measurement, and it ideally makes use of the minimal quantity of fabric to make all that work. After-effect evaluation can let engineers know the way a lot of the case was burnt within the blast, how a lot launched outward as shrapnel, and what kind of harm the blast prompted. This may be utilized to each form of blast, from a grenade to an artillery spherical or a plane-dropped bomb.
Understanding the precise impression of a bomb on its environment, in helpful element and simply processed knowledge, may also enhance the design of armor.

Mike Maffeo is a senior engineer with DECOM who works on armor design for troopers on foot. He stated: “FRAG‐CT seems to be to be an actual recreation changer in getting new fragment information rapidly for armor evaluation and vulnerability evaluation. With all the information that’s being collected by FRAG‐CT, it opens alternatives to extend the constancy of the modeling and evaluation.”
Very similar to modeling improves the flexibility of the Military to design new explosives, it additionally improves the flexibility of the Military to design armor proof against new explosions. Maffeo continued: “A few of these newer munitions have uneven (non‐symmetric) burst patterns which can be tough to mannequin with out the correct knowledge. FRAG‐CT ought to permit us to get this kind of knowledge rapidly.”
For now, the appliance of FRAG-CT appears restricted to tester workouts and managed explosions, somewhat than precise in-field evaluation. However, utilizing software program to shorten the time it takes to grasp a blast will enhance weapon and armor design now, and certain means that future knowledge evaluation instruments may see use past the laboratory setting.
