Impact tests on inclined stainless steel fins
Stainless steel fin models inclined at a 10-degree angle with respect to the direction of impact were tested at Sandia Laboratories drop table test facility. Force transducer and accelerometer data gave load-time and acceleration-time data from which the peak impact force and absorbed energy were obtained. Results of the tests showed that the peak dynamic load on a 10-degree fin due to a 13.4 m/s (44 f/s) impact can be more than three times its static load capacity and that 10-degree fins deform by buckling rather than by bending over. The energy-absorbing capacity of 10-degree fins showed some decrease but no dramatic difference when compared with similar fins that were impacted normally.
