Parametric Optimization of Amphibious Aircraft Profile Sketch

The article is about the search of optimal fuselage shape of an amphibious aircraft in terms of aerodynamic characteristics. In order to find the optimal fuselage shape we used the parametric optimization method.This article proposes an approach that allows you to solve a wide range of engineering problems in finding the appropriate form of an aircraft. In order to check the correctness of the proposed approach to find the optimal fuselage shape of anamphibious aircraft wing parametric optimization was carried out.The simulation of the aircraft airfoil geometry and the amphibious aircraft fuselage was carried out in the SolidWorks. As a result of aircraft wing optimization one of the possible forms coincided with the Mynk-6 airfoil-shaped profile. The aerodynamic characteristics of the wing were defined using the finite volume method in the ANSYS software package. The found values coincided with the theoretical data, which indicates the correctness ofthe boundary conditions and the optimization technique. Additionally, the converging of the solution of the block-structured and tetrahedral finite element model was tested.Using a similar method of parametric optimization with both ANSYS and IOSO the appropriate fuselage shape of the amphibious aircraft is obtained. The optimum fuselage shape has significantly better aerodynamic characteristics compared with a non-optimized model.
