Description

This demo presents a model of simulation of a RAT (Ram Air Turbine) system used as emergency power system in an aircraft. Electrical, mechanical and hydraulic components are modeled respectively with SimPowerSystems, SimHydraulics and SimMechanics. The advantage of a model spanning different physical domains is to have on overview of basic interactions between all the major components. It is most useful in the early stage of the design of a future system, in this case an hybrid emergency system for the more electrical aircraft.
The power system is composed from a wind turbine (15 kW) connected to an electrical synchronous generator. The shaft of the turbine is also connected to a pump that supplies a hydraulic circuit linked through a servo valve to a cylinder. The motion of the rod is transformed into rotational movement on the axis of the Aileron. A position controller is used so that the deflection angle tracks a given reference by controlling the servo valve.
