Aerodynamic Characteristics Simulation Analysis of a Certain Type Changed Wing Drone Aircraft Based on CFD

Abstract:

This paper aims at the change of the whole machine aerodynamic characteristics after a certain conventional type drone aircraft changing plateau type large wings , using CFD technology to establish the nomal type and plateau type model, doing numerical simulation calculation of the whole machine's aerodynamic performance under the condition of no-load, using the simulation calculation results and combined with actual flight data, compared and evaluated the aerodynamic characteristics of the drone aircraft installed different airfoil, the results show that change plateau type large wings, obviously improve the lift-to-drag performance of the whole machine, increase the range of effective attack angle, and the little change of flight performance, scientific and feasible.
