Theoretical Framework for the Simulation of Transport Aircraft Flight

摘要

This contribution presents a novel simulation theory for a complete fixed-wing aircraft. Novel methods are presented for flight mechanics (fuel planning), turbofan engine simulation (indirect and inverse mode), thermophysics integration (tire temperature on the ground and fuel temperature in-flight) and aircraft noise. At the fundamental level, the framework presented addresses a shortfall in multidisciplinary integration in aircraft flight, including economic operations, preliminary design and environmental emissions. The models introduced are based on first principles, supplied with semiempirical correlations, when necessary. Validation strategies are introduced for component-level analysis and system integration. Results are presented for geometry models, specific air range and optimal cruise conditions, payload-range performance, fuel temperature of a wing tank, tire heating during normal takeoff, aircraft propulsive (jetozzle), and nonpropulsive (landing gear) noise. Selected results are shown for the Boeing B777-300 and the Airbus A380-861.
