Crashworthy Gunner Seat Testing Program
Abstract
A crashworthy gunner seat swivel concept developed under a previous contract was refined and detail drawings were made. Six seats were fabricated, four for static testing and two for dynamic testing. Modifications were made after the first four static tests. Additional static tests were successfully performed on two of the modified seats. A vertical drop test and a horizontal dynamic test were performed on the remaining two modified seats. The vertical test was successful but the horizontal test resulted in failure due to the seat not automatically rotating to a forward-facing position. Five seats were refurbished and modified to eliminate the deficiencies found in testing and to convert four seats to a fixed side-facing configuration. The swivel seat was dynamically tested in the horizontal plane with the seat facing 30 degrees to the direction of impact. The test results were successful and the dummy accelerations were reduced to well within human tolerance limits. Both types of seats tested have advantages as well as disadvantages.
