Linear dampers provide resistive forces to provide improved feel for aircraft control surfaces or to dissipate energy from aerodynamic or mechanical loads. Arkwin dampers endure millions of cycles undergoing high side loads in dither conditions in the most demanding environments. Designs can be self-contained with integral reservoir or can be connected to the hydraulic system. Stepped damping curves can be developed to suit the application’s need. Select Platforms Sikorsky S-92 Sikorsky S-76 Linear Dampers consist of a mechanically driven piston mounted in a housing assembly. The housing contains rate control valves, reservoirs, and other components like servicing provisions. Dampers can be combined with other functions such as trim control or component extension by solenoid command. Applications Include: • Helicopter Main Rotor Head Damper • Pedal Damper and Trim Actuator • Landing Gear Damping Operational Characteristics: • Single or stepped damping profiles • High frequency dithering • Electrical trim control and position override Key Features: • Integral reservoirs • Thermal expansion protection • Fill Indication • Servicing provisions • Self-contained or integral with hydraulic system Platforms S-76 S-92 Design Characteristics: • Hydraulically balanced piston with mechanical override • Multiple operating fluid options • Internal controls provide precise resisting force as a function of piston velocity - Active and passive damping rate valves Bypass valves • Multiple mounting options • High side load tolerance • External adjustment of damping force available
