The Boeing Chinook is a tandem rotor, medium-lift helicopter that meets tactical and combat support mission requirements for military forces around the world. The Chinook is the worlds most reliable and efficient transport helicopter, capable of handling useful loads up to 24,000lbs. and a maximum gross weight of up to 50,000lbs. (22,668kg). Its tandem rotor configuration also provides exceptional handling qualities that enable the CH47 to operate in climatic, altitude and crosswind conditions that typically keep other helicopters from flying.
Eaton is a key supplier of fluid power, fuel systems, electro-mechanical, fluid conveyance, power and load management and avionics products on the CH47. Eaton’s contribution to the EPUSHA system consists of two main components: an electric motor pump (EPUSHA pump) and a control box. These components, bundled with a wiring harness, mounting plate, and miscellaneous hardware, are available as a modification kit that can be installed to eliminate the need for hand-pressurizing the hydraulic accumulators required to start a CH47 auxillary power unit (APU). The CH47’s 3000psi hydraulic systemt incorporates three transmission driven pumps, power transfer units, main engine starters, rescue hoist drive motor, cargo winch drive motor, APU starter/pump and hydraulic accumulator and brake master cylinder assembly.
