Components for Rotorcraft

Product catalog summary

Overview
ITT Enidine specializes in providing high-quality engineered components for rotorcraft applications, focusing on meeting demanding requirements with flexibility and efficiency. Their offerings include high-capacity laminated bearings, Frahm dampers, interior and equipment isolators, hydraulic control dampers, and lead lag dampers.

High Capacity Laminated Bearings
These bearings are crucial for rotorcraft transmissions and rotor systems, supporting loads and transmitting motion to helicopter blades. Key benefits include reduced in-flight vibration, longer lifespan, improved reliability, easy inspection, and reduced maintenance due to no lubrication requirements.

Frahm Dampers
Frahm dampers are dynamically tuned vibration absorbers used to reduce vibrations in helicopter airframes and rotors. They consist of a mass, springs, enclosure, bushings, and tuning washers, designed to counteract undesirable vibratory forces.

Interior and Equipment Isolators
ITT Enidine offers advanced isolators for interior panels and equipment, providing dynamic isolation, noise attenuation, and fail-safe torque resistance. The strut-integrated isolator offers weight and performance benefits, with confirmed exceptional performance in engine and APU installations.

Hydraulic Control Dampers
These dampers are designed for energy absorption and hydraulic motion control, providing precise resistance for helicopter controls and preventing jamming. They are custom-designed for specific application requirements.

Engineering and Manufacturing Capabilities
ITT Enidine utilizes advanced software for dynamic analyses and has proprietary programs for predictive analysis. Their in-house molding facility allows for rapid prototype development, with capabilities including high-pressure and high-volume injection presses.

Lead Lag Dampers
Lead lag dampers use various technologies, including hydraulic, visco-elastic, and hybrid systems, to respond to rotor system design requirements. ITT Enidine has invested in specialized testing equipment to enhance their lead lag technology.
