hinged section
Available on back-order
Description
The 8A-1516-20 is a hinged section of the tail drive shaft assembly used in Mi-series helicopters. It transfers torque through the tail boom while accommodating angular displacement, structural flex and vibration inherent to rotorcraft transmission operation.
This component links rigid shaft elements within the 8A-1516-000 shaft system and works together with other hinged and straight sections to maintain continuous torque delivery to the tail rotor. The section is designed to operate at high rotational speed under torsional loads and dynamic stress.
Installed on core and modernized variants of the Mi-8 helicopter family, the section is supplied individually or as a component in complete tail shaft service kits.
Alternate designations: 8A-1516-20, 8А-1516-20, 8A151620, 8A.1516.20 — all refer to the same hinged shaft section.
