Gas turbine blade impulse body module

An impulse body module group with at least two impulse body modules, which are identical in construction, for a gas turbine blade, wherein each of the impulse body modules comprises

• a housing, which is of one piece and which has a cavity, which is closed in an airtight manner, by a cover, which is joined to the housing in a material-bonded manner, and in which a single spherical or cylindrical impulse body is accommodated with play of movement in at least one first direction of impact,
• wherein the housing of each of the impulse body modules has no additional cavity and has no additional spherical or cylindrical impulse body accommodated with play of movement in at least one direction of impact, and
• wherein at least two impulse body modules are joined together in a non-destructive detachable manner, in a permanent manner, in a friction-fitting manner, in a form-fitting manner, in a material-bonded manner, by at least one clamping element, are arranged one above the other in the first direction of impact or are arranged next to one another transverse to the first direction of impact.
