Beschreibung:
Purpose - Find optimal flight and design parameters for three objectives: minimum fuel consumption, Direct Operating Costs (DOC), and environmental impact of a passenger jet aircraft. --- Approach - Combining multiple models (this includes aerodynamics, specific fuel consumption, DOC, and equivalent CO2 mass) into one generic model. In this combined model, each objective's importance is determined by a weighting factor. Additionally, the possibility of further optimizing this model by altering an aircraft's wing loading is analyzed. --- Research limitations - Most models use estimating equations based on first principles and statistical data. --- Practical implications - The optimal cruise altitude and speed for a specific objective can be approximated for any passenger jet aircraft. --- Social implications - By using a simple approach, the discussion of optimizing aircraft opens up to a level where everyone can participate. --- Value - To find a general answer on how to optimize aviation, operational and design-wise, by using a simple approach.
