Standard Atmosphere ModelThis page describes the Standard Atmosphere model and how it works.The Standard Atmoshere Model receives the aircraft's current altitude and computes the density, pressure,temperature, and speed of sound at that altitude.Source Code:std_atm.c C file written in S-Function format that computes the pressure, density, temperature, and speed ofsound for any given altitude.Atmosphere.mdl Simulink block diagram that graphically displays the inputs and outputs to the C-code.54
Engine ModelThis page describes the Engine model and how it works. The Engine Model calculates the thrust generatedby each engine based on the engine type, static sea level thrust, and the density ratio. The 5 engines that aremodeled are a propeller piston engine, turboprop, hi-bypass, and a turbojet with and without afterburnercapability.The Engine Model consists of a Spool Up / Spool Down Model which gives the engine a realistic feel byadding a .25 second time delay on spool up and a .5 second time delay when spooling down.Included is the work performed by the Spring 2000 Aero 320 class who developed the Engine Model,Tested it, Calibrated the Throttle as well as the Instruments. Engine Model SimulationBelow is the Engine Model Diagram,Source Code:Spring AERO 320 class Engine Model Simulationengine_mod.cC file written in S-Function format that receives the throttle inputs from the stick model, thencalculates the engine model variables.engine.mdlSimulink block diagram that graphically displays the engine model outputs based on throttleposition. Embedded is the spooling model.spool.cC file written in S-Function format that computes the time delay for the throttles based on whetherthey are spooling up or spooling down.spooltst.mdlSimulink block diagram that graphically displays the spool model outputs based on throttleposition.55
