FIELD: transport.
SUBSTANCE: proposed test bench comprises kinematic and hydraulic systems, ACS, power system and destruction protector operated on principle of "vulnerability". Mechanically closed kinematic system comprises two kinematic circuits with end reduction gears to reproduce helicopter transmission tail assemblies speeds corresponding to operating speeds. Kinematic system comprises torque loader composed of gearing that ensures preset torques corresponding to operating torques. Said power system allows reproducing radial and axial forced acting on tail rotor shaft that correspond to operating forces. Said system comprises coupled support, screw mechanisms, radial and axial force loaders with appropriate force transducers.
EFFECT: higher safety, reliability and power savings.
