Patent ID: 7066040

Claim:
A testing stand for a helicopter transmission ( 2 ) having an output side rotor shaft ( 4 ) and at least one drive-side input shaft ( 10 , 12 ), the testing stand is connected to the transmission by shafts ( 6 , 8 ) and connection couplings ( 14 , 16 , 22 ) with at least one testing stand side shaft connection, whereby the helicopter transmission ( 2 ) is capable of swiveling about the output side rotor shaft axis ( 4 ), and at least one actuator ( 28 , 30 ) inhibits swiveling of the helicopter transmission ( 2 ) about the output side rotor shaft axis ( 4 ) in equalize shifting of the helicopter transmission ( 2 ) on the connection couplings ( 14 , 16 , 22 ) occurring under load, and the helicopter transmission ( 2 ) is clamped to the testing stand ( 20 ) by connection elements ( 24 , 26 ) which are elastic with relation to swiveling deflection.
