Design of Elevons, Wings, and Performance Investigation for A Blended Wing Body UAV

Objectives: To study a hybrid VTOL- Blended wing body design for its wings and elevons perform CFD simulations with the wings. The steps designing configuration Elevon positioning involve different variables giving rise to large number of possibilities control surface. In current methods, have been proposed selection optimized validated model. Methods: Meta-heuristic methods like genetic algorithms are used arriving at favorable solutions Matlab coding is written initial draft geometry, selected geometries iterated in XFLR5 stability control, later around fluid domain. Elevons surfaces generally installed tailless aircraft wing's trailing edge. It applies roll pitching force as it combines functionality both rolling control. Design space was mathematically plotted solved using MATLAB decide elevons, configuration, their positions.Findings: Initial aoa, structural maneuverability enhanced aerodynamic performance BWB UAV. this presented paper drag coefficient designed UAV comes out be precisely 0.02216 computational modeling. Variation curve Lift aspect ratio angle attack. Post-processing results pressure forces velocity profile on Wings accurately validate method surface optimization. Novelty: Designed has increased lift ratio, reduced weight airframe which improves performance. phase highly iterative, Through research paper, an attempt made develop methodology investigation against requirements that makes more helpful practical use increasing endurance efficiency aircraft.
