Abstract
This research is involving studies of hydraulic components in rotorcraft and the effect of pressure, velocity and displacement of piston in hydraulic cylinder to rotorcraft maneuver. Research also cover the real mechanism of hydraulic components in rotorcraft especially helicopter. Hydraulic components equations and parameters also had been study in creating physical modeling of hydraulic components. Real helicopter hydraulic system had been study using manuals and production magazines. SimHydraulics® software in MATLAB® 7.5 (2007b) is use in build up the physical model for hydraulic system simulations. Through this research new hydraulic system physical model been recreated as simplify to the complicated hydraulic system in real working condition of helicopter maneuver. Physical modeling will simulate the real working system as better understanding to the people who want to learn hydraulic in rotorcraft. Result from this research should give people enough basic information on how real hydraulic system in rotorcraft works especially system that controls the main rotor. The effects of changing certain area in hydraulic cylinder also will show how pressure, velocity and piston displacement also change. Hydraulic system for helicopter Eurocopter AS350 will be the reference of actual hydraulic system in this research.
