A series of dynamic tests with the Glatz prototype H-60 troop seat was performed to determine occupant protection during a crash event. These were re-tests of the Glatz prototype seat detailed in AFRL-RH-WP-TR-2012-0103. The re-tests were of Combined Vertical tests at which the Glatz prototype seat structurally failed during the initial study due to the manufacturer deviating from design drawings. A Pure Horizontal test was also conducted to determine structural strength of the Glatz prototype seat. Biodynamic response data were compared to standard injury criteria recommended by the Full Spectrum Crashworthiness Report as well as other seats tested at the same conditions. A total of eight tests were conducted. Additional manufacturing errors were found in several of the prototypes. The Glatz prototype seat structurally survived impact conditions at which it failed during the original troop seat comparison testing. Peak lumbar Z forces were higher for the Glatz prototype seat compared to other seats tested, and peak resultant chest accelerations were also generally higher than the other seats. While structurally successful, it appears the seat will require additional modifications to improve energy attenuation capability during a crash event. In the Pure Horizontal test, the seat structurally failed, suggesting that further redesign is necessary.
