This document describes the nonlinear aircraft simulation model ADMIRE. It describes the main aircraft model, the flight control system, actuators, the sensor models and the uncertainty parameters with respective limits. This document also contains a description on how to properly install and run the model. The ADMIRE describes a generic small single seated, single engine fighter aircraft with a delta-canard configuration, implemented in MATLAB/SIMULINK Release 13. The model envelope is up to Mach 1.2 and 6000 m altitude. The model is augmented with a longitudinal flight control system (FCS) that controls the pitch rate at low speed and the load factor at higher speeds, and a lateral controller that controls the wind vector roll rate and the angle of sideslip. The longitudinal FCS also contains a very rudimentary speed controller. The model has thrust vectoring capability, although this is not used in the present FCS. For the purpose of the robustness analysis, the model is extended with the possibility to change some predefined uncertainty parameters within prescribed limits. The uncertainty parameters consist of configuration parameter-, aerodynamic-, actuator- and sensor (air data)-uncertainties. The model can be trimmed and linearized within the entire model envelope.
