Abstract:

The objective of this program was to design and test rotor blades that are more tolerant of ballistic damage than current blades. Eight blade design concepts were conceived and compared with a previously tested baseline blade. Three of these concepts were selected for fabrication and were ballistically tested. Analysis of all hits showed a significant increase in survivability, as well as a penalty in blade weight, for each of the three designs.
