Digital Data Recorder for Gauges in High Speed Weapons During Survivability Testing

The ability to collect data for conventional munitions in conditions of increasing acceleration and duration for hard target penetration is needed. Survivability and functionality of an electronic data recorder exposed to these acceleration levels (up 120,000 g) and shock loads is necessary as a result of higher velocity weapons and the use of precursor shape charge warheads to soften the target in front of a penetrating advanced design warhead. The electronics must survive this precursor charge at least 95% of the time, continuing to record data throughout the entire event. Results from this phase will include a proof-of-concept or prototype design of a new multi-channel digital data recorder effective in high g loads (100,000 g for 2 msec; 30,000 g for 5 msec) and high velocities (>2,500 ft/sec). The prototype will be able to collect data from three internal accelerometers at 1,000,000 samples per second per channel. Key components of the system will be tested in a high g environment to confirm component selection and support design effectiveness.
