| Abstract | Recent incidents have shown that bird impact can cause catastrophic damage to an aircraft tail unit. One of the proposals for minimizing this damage was the filling of the tailplane structure with a deep layer of plastic foam. A small gun was available for throwing "birds" at structures and this was used to investigate the impact absorption properties of foam and the protection it would offer to a tailplane. It was concluded that the direct impact of a 2 lb. bird at 240 mph on the nose of the tailplane tested could cause catastrophic internal damage. When the tailplane was filled with the foam described, the internal damage was greatly reduced, but the energy transmitted to the tailplane mounting was increased to a degree which raised the possibility of failure of the tailplane attachments to the fuselage. It is concluded that other methods should be sought to protect the tail unit from bird impact damage. |
