You can view and edit data in the model workspace directly by using the Model Explorer, which is launched using the Modeling > Design > Model Explorer menu item. This file is loaded by the model into the model workspace. When the pilot moves flight controls, those movements are converted into electronic signals, which are then interpreted by the aircrafts flight control. Parameters for the model are stored in a file named slexAircraftData.m. You will feel the controls become smoother as you trim the plane. Trim the aircraft for straight and level flight. Once youve reached your desired altitude, this power should be set to around 75. If you close a model scope, such as for batch simulations, you can later reopen it by double-clicking the "scope" icon on the signal of interest. Every airplane has an engine power setting optimized for the cruise phase of flight. Found on Simulation > Prepare > Viewers Manager, the Viewers and Generators Manager allows you to instrument your model without having to add blocks to the model. The Viewers and Generators Manager was used in this model to create the model scope for viewing signals, Scope1. BAE Systems will be developing a full-authority digital flight control system that provides fly-by-wire flight control, integrated flight and propulsion control, aircraft center-of-gravity computation for stores and fuel contents, structural air loads alleviation, and carefree handling performance.
A simplified Dryden wind gust model is incorporated to perturb the system. First order linear approximations of the aircraft and actuator behavior are connected to an analog flight control design that uses the pilot's stick pitch command as the set point for the aircraft's pitch attitude and uses aircraft pitch angle and pitch rate to determine commands.
