Abstract
A test rotor blade includes a blade body and a plug. 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 hole. The blade body includes a first side wall and a second side wall. The first side wall extends between and to the hole and the first side surface. The second side wall extends between and to the hole and the second side surface. The plug is disposed within the hole. The plug forms a perimeter surface extending about the axial centerline. The perimeter surface includes a sealing surface portion and a diverging surface portion. The diverging surface portion forms a gap between the plug and the blade body. The gap is disposed between the first side wall and the diverging surface portion.
