• One of the important subjects is the impact energy absorption system applied to the aircraft structure in order to keep the safety of human beings under the aircraft crash landing circumstances. For this purpose, the improvement of major energy absorption component such as landing gears, sub-floor structures and crew seats are necessary for rotorcrafts and light aircrafts. The focus of this study is the design and testing of structural element for sub-floor structures. Some energy absorbing structural element concept (the square taper tube, the triple square tube) together with some initiator concepts (film type, hole type) are examined on static characteristics. The result is evaluated based on specific energy absorption and load uniformity ratio. The square taper tube with the film type initiator possesses acceptable crash behavior.
