Abstract
A test rotor blade for an aircraft engine bladed rotor includes a blade body. The blade body extends between and to a leading edge and a trailing edge. The blade body forms a first side surface and a second side surface. The blade body forms a leading-edge pocket at the leading edge, a trailing-edge pocket at the trailing edge, and a hole extending through the blade body from the leading-edge pocket to the trailing edge pocket. The blade body includes a first side wall and a second side wall. The first side wall has a first wall thickness extending between and to the first side surface and the hole. The second side wall has a second wall thickness extending between and to the second side surface and the hole. The second wall thickness is 0.4 to 0.9 times the first wall thickness.
