ABSTRACT:
A fluid damper blade made by bending a sheet of metal into a U and bringing the edges of the U together to form the trailing edge of the blade, the two edges of the U being of castellated form so that they interlock when brought together, with the castellations being bent over so as to embrace a reinforcing locking rod extending the full length of the blade trailing edge. This gives the blade enhanced rigidity and increased resistance to bending and twisting stresses. In addition, welding of the edges of the U is made unnecessary.
