3.2.1.2 Engine ModelThe engine model in Figure 21 computes the thrust generated by the aircraft’sengine(s) based on the throttle setting, altitude, and static seal level thrust. 13The enginecan either be a propeller, turboprop, high by-pass ratio engine, or jet engine withafterburner or without. 14Other necessary inputs are left and right engine fuel capacity,propeller efficiency (if a propeller driven engine), TSFC, and afterburner TSFC. It thencomputes the thrust generated based on these inputs and calculates the engine RPM,temperature, fuel flow, and nozzle position.Figure 21: Engine Model24
3.2.1.3 Standard Atmosphere ModelThe Standard Atmosphere Modelis shown in Figure 22. This modelcomputes the speed of sound, density,pressure, and temperature, based onaltitude. This model also takes intoaccount the different altitude regimes thatthe aircraft is flying in and applies theFigure 22: Standard Atmosphere Modelappropriate equations.3.2.1.4 SixDOF ModelThis model computes theaircraft’s position and orientationalong with velocity, angular rates,angle of attack, sideslip, andtranslational accelerations. TheSixDOF model in Figure 23 treatsthe aircraft like a point mass. Itconverts the forces, moments,Figure 23: SixDOF Modeland control inputs generated by the aircraft to compute the above states. The term sixdegrees of freedom refers to the translational and rotational positions: X, Y, Z, and Psi,Theta, Phi. The model also reads in a Standard Aircraft Data (SAD) file, which containsthe aircraft’s stability derivatives and initial conditions.25
