ACCESSORY DRIVE MISSION POWER SYSTEMS
In 1996, we designed our first accessory drive hydraulic system for the Bell OH-58 / 206B helicopter. Today Kawak produces accessory drive hydraulic systems for SA315B Lama, Bell 212/ 412 in both high flow and firefighting configurations, CH54B Sky Crane, B47, Hiller, Hughes 500, Bell UH-B, H, L, & K, Sikorsky S64E & F, Sikorsky S-61, Kaman K-1200, etc. Many of these require one of our custom designed accessory drive gearboxes in order to draw power from the engine gearbox or rotor transmission.
As well as providing existing accessory drive system product lines Kawak continues to develop new systems for all types of aircraft and applications.
