Abstract
The nose wheel steering system for aircraft-on-ground maneuvering is simulated on MATLAB-SIMULINK platform to estimate the effort (Torque) required for steering. Estimation of steering torque is essential for steering actuation system sizing. Aircraft steering model includes Nose Landing gear (NLG) model, Aircraft Dynamics model, and Tyre model. Steering Actuator is sized based on the steering torque and 3000 psi (or) 210 Bar as system pressure constraint. Flow rate requirement is also estimated for the given steer rate. Generation of flow and pressure data for steering system are essential in sizing of centralized hydraulic pumps which support flight control surface actuation systems, thrust reversal systems, Landing gear retraction, Braking etc.
