ABSTRACT:
Airship tail fins (20) deflect under excessive load on axii (108,110) to protect the airship hull (22) and also reduce angles of attack to disturbing airflow. A propulsion engine (24) may be mounted to the tail fin structure. A longitudinally elongated roller (36) may be mounted to the lower tail fin to act as landing gear. Two widely separated lower tail fins may control pitch and roll when moored by providing secure attachment points, as at shaft (38), for ground handling.
