Planform Load Distribution Mapping for Straight Tapered Wings with Linear Twist

摘要

Load distributions used for preliminary airplane structural analysis are generally based on simplistic load distributions as outlined in the Federal Aviation Regulations or based on Computational Fluid Dynamics (CFD) simulations. The simplistic load distributions are very rudimentary and are used only when data from reliable methods are unavailable. Computational Fluid Dynamics simulations are very time consuming. The model/mesh definition is very important in getting good CFD results and often lead to tedious and time consuming model discretization. The Planform Load Distribution Mapping (PLDM) method is a Quasi Panel Code developed specifically to aid load generation for structural analysis. The computation times for the PLDM method are a fraction of the computation times from CFD simulations. The model discretization times are minimal as the input is tied in with the parameter definition of the Advanced Aircraft Analysis (AAA) software.
