Projectile Data logger

When projectiles are being fired, they are exposed to extreme environmental conditions inside the gun barrel. There is a need to record these conditions for the purpose of designing of projectiles. With this device different areas of the projectile can be instrumented to record the stresses experienced. The environmental stresses could include temperature, acceleration, vibration, pressure, force, torque and strain. Mid? proposes to design a reusable device that will record these variables as well as crack detection and information from the guidance system. The proposed system will be a self-powered, high sample rate, robust, small and reusable data recorder. Mide's design approach is to use the high-density properties of a mixed logic ASIC (Application-Specific Integrated Circuit) to combine all the analog circuitry in a compact area. When using discrete components a high percentage (>90%) of the space is under utilized, because of the area around each individual IC (Integrated Circuits) used for interconnection and decoupling. The IC itself also has large under utilized area as typical silicon needed for the function is extremely small but the package has to be large to enable mounting and electrical connections. With an ASIC there is a high density of silicon, shrinking the physical area.
