Forward Ballistic Rocket Sled in Action
On Dec. 9, 2015, Sandia National Laboratories successfully conducted a forward ballistic rocket sled calibration test at the 10,000-ft. track. The mass mock test unit hit the target point within a fraction of an inch after a 73-foot free-flight at 260 miles per hour. The test met all impact requirements and all dynamic measurements were successfully recorded. The high speed 3D imaging diagnostics shown in this video highlight the unique precision measurement capabilities available at Sandia's Validation and Qualification Sciences Experimental Complex.
