The Methods of Designing a Polymer Composite Wing Using Parametrical Modeling. Part 1. The Rationale for Selecting Wing Geometry and the Calculation of Airloads

The wing is one of the basic elements of a jet airframe, and polymer composite materials are used to ensure its mass efficiency. Wings manufactured from these materials are designed at aeronautic corporations in the USA, France, Great Britain, Italy, Germany, the PRC and Russia. However, the design work combining the structural arrangement and individual load-bearing elements of the wing is scattered. Therefore, it is important to develop methods of designing a polymer composite wing that combines the structural arrangement and load-bearing elements. This paper presents the first part of the calculations using the proposed method. It describes the rationale for selecting wing geometry and airloads using parametrical modeling of 12 geometrical models of the wing made of polymer composite materials. It is determined that the smallest airloads occur in a trapezoidal sweepback wing with a straightened edge and an asymmetrical airfoil.
