ANALYSIS OF STATIC AND DYNAMIC AEROELASTIC CHARACTERISTICS OF AIRPLANE IN TRANSONIC FLOW

摘要

This paper describes the method developed in TsAGI for taking into account specific responses of an elastic airplane in transonic flow. For the analysis of strength, static and dynamic aeroelasticity characteristics the mathematical model of an elastic airplane is created in the ARGON system. New approach is based on Transonic Time-Harmonic Code for aeroelastic application. Linear flutter analysis in the frequency domain is supplemented with an effective algorithm/procedure of aerodynamic influence coefficients computation using time-harmonic solutions of the Euler equations in transonic viscous flow. It is available for rather complex airplane configurations.
