AERODYNAMIC LOAD OF AN AIRCRAFT WITH A HIGHLY ELASTIC WING

Blog Article

In this article, a method for calculation of air loads of an aircraft with an elastic wing is presented.The method can predict a redistribution of air polly pocket pineapple purse loads when the elastic wing deforms.Unlike the traditional Euler or Navier-Stokes CFD to FEM coupling, the method uses 3D panel method as a source of aerodynamic data.This makes the calculation feasible on a typical recent workstation.

Due to a short computational time and low hardware demands this method is suitable for both the preliminary design stage and the load evaluation stage.A case study is presented.The study compares a glider wing performing a pull maneuver at both rigid and and elastic state.The study indicates a significant redistribution of wuh722222ale6l4 air load at the elastic case.
