This paper presents the analysis of the dynamic behavior of a heavy transport helicopter tail rotor blade made of composite laminated materials after ballistic damage made by the bullet of 7.9 mm caliber shoulder weapons. Penetrating damages made in the root part of the tail rotor blade spar have been analyzed. The blades have been made of composite laminated materials. The test program for the tail rotor helicopter blades has included dynamic testing non-damaged and damaged blades in full-scale. Based on the results of vibratory testing and fatigue testing an assessment is made about the vulnerability and the survivability of the heavy transport helicopter tail rotor blade made of composite laminated materials after ballistic damage made by the bullet of shoulder weapons.
