The estimated aerodynamic characteristics of a closed carrying surface finite element method
Journal Title: Механіка гіроскопічних систем - Year 2015, Vol 0, Issue 29
Abstract
The article the calculation of the basic aerodynamic characteristics of a closed carrying surface using FEM. The modeling of flow around the object of research by using the finite element method having higher accuracy. Compliance with the results of FEM calculation and the results of physical experiment for aircraft of various schemes repeatedly confirmed in practice, aerodynamic design, which is clearly represented in the works. Polar CLS presented in the form of dependency, suggest that the proposed new form of the CLS without any additional boundary layer control means provides a steady airflow around the bole in a much wider range of angles of attack than the wing of the aircraft of the classical scheme. The increment of the resistance caused by the increase in lift force, certain FEM and PVM is almost identical. This allows for a simpler and less demanding of computing means PVM for calculating the aerodynamic characteristics of complex layout.
