HarcoSemco’s harnesses, featuring unique elements like rotating clamps, customized connector overmolds, and high-flex wiring, are designed for extreme dynamic applications. For blade-fold and ice protection systems on helicopter blades, both main and tail rotors, these harnesses handle high-frequency blade rotation and wide variations in blade pitch-up/pitch-down, tilt/flap, and lead/lag angles. These factors subject the harnesses to extreme structural and fatigue stress during operation. HarcoSemco’s harnesses excel under these conditions while maintaining a high level of environmental protection, essential for external installations.
HarcoSemco validates dynamic harness designs using in-house fatigue life test fixtures that replicate the specific movements of the application. These fixtures can be modified to suit the intended platform and installation. The typical harness test to operation ratio is 40:1, meaning one hour on our test fixture represents 40 in-flight hours.
