RÉSUMÉ

A method and algorithm for design studies of the characteristics of aeroelasticity and weight efficiency of closed structures in the Ritz polynomial method are developed. The algorithm is integrated into the ARGON software package. The application of the method and algorithm for an aircraft with a large aspect ratio wing with a strut is considered.
