Abstract : A flutter-vane fuze-arming technique is being developed for anti-personnel/anti-materiel bomblets but which should have application in other weapons also. The energy for arming is provided by a small vane whose fluttering motion is induced by the ram air. This new arming technique is superior to the conventional rotary-type system because of its inherent capabilities to discriminate a prescribed threshold air velocity and to operate at a constant frequency without the use of a governor. In this report are presented the design and performance relationships for the flutter-arming vane which have been established using a special, controlled-geometry test chamber. These relationships permit computation of the flutter frequency, flutter start-up velocity and the power output for a range of environmental conditions and model geometries. (Author)
