Problem Statement

Redesign the inert SVR (Setter Verification Round) that models a PABM (Programmable Air-Bursting Munitions) to withstand wear between battery contacts and electronics. The SVR must withstand cycling through the testing system in excess of 1000 times. In addition, it must be able to operate under numerous environmental conditions. Finally, the chosen design must be a CG match to a live PABM round.

The current SVR being used in ATK's system can be seen in Figure 1, below:

Figure 1 - SVR (Actual)

In order to take a closer look at the inside of the SVR, a CAD drawing is needed. Figure 2, below, illustrates the SVR being used currently.

The problem with this current design of the SVR is that the batteries are being crushed during testing. In order to see the damage being done to the batteries, before and after pictures are needed. This comparison can be seen in Figures 3 and 4, below.

As mentioned previously, our task is to redesign the current SVR being used at ATK so that it can withstand cycling through their system in excess of 1000 times.
