TAKING INTO ACCOUNT AERODYNAMIC HEATING IN AEROELASTICITY PROBLEMS
要約
A method and algorithm of taking into account thermal stresses when calculating aeroelasticity characteristics of an aircraft are developed. The algorithm is based on applying the polynomial Ritz method. Verification and validation of the mathematical model are considered. Investigations on the influence of aerodynamic heating on the aeroelasticity characteristics of a supersonic business airplane are carried out.
