Final Report for the Creation of a Physics-Based Ground-Effect Model, Phase 2 - Inclusion of the Effects of Wind, Stratification, and Shear Into the New Ground Effect Model

The reduction of the separation of the leading and following aircrafts is desirable to enhance the airport capacity provided that there is a physics-based operational model applicable to all regions of the flight domain (out of ground effect, OGE; near ground effect, NGE; and in ground effect, IGE) and that the quality of the quantitative input from the measurements of the prevailing atmospheric conditions and the quality of the total airport operations regarding the safety and the sound interpretation of the prevailing conditions match the quality of the analysis and numerical simulations. In the absence of an analytical solution, the physics of the flow is best expressed by a mathematical model based on numerical simulations, field and laboratory experiments, and heuristic reasoning. This report deals with the creation of a sound physics-based real-time IGE model of the aircraft wake vortices subjected to crosswind, stratification and shear.Sarpkaya, TurgutLangley Research CenterGROUND EFFECT (AERODYNAMICS); STRATIFICATION; WIND EFFECTS; WIND SHEAR; PHYSICS; REAL TIME OPERATION; AIRCRAFT WAKES; VORTICES; TAKEOFF; AIRLINE OPERATIONS; METEOROLOGY; MATHEMATICAL MODELS; HEURISTIC METHODS; AIR TRAFFIC CONTROL; AIRCRAFT SAFETY...
