Abstract
A set of plates, one rigidly mounted to the strut and the others to the craft structure. The plates are held together and are interconnected to one another by several sets of dowel pins which are sequenced to shear when an impact load at the foil rotates the strut. Thereafter, a pair of additional energy absorber devices, positioned to the left and right of the strut mounted plate, will likewise absorb energy until a rigid stop is obtained. Finally, a tang portion on the strut mounted plate will be sheared by the rigid stop at a load below which the strut will obtain damage.
