The Ffa Wing Body 83 Computer Program. A Panel Method for Determination of Aeroelastic Characteristics at Subsonic and Supersonic Speeds

摘要

A panel program for rigid airplanes was extended for the calculation of aerodynamic characteristics of configurations with elastic wings. The equations for a direct solution of the deformed shape and its loading are outlined. Input modifications are described. The program was used with an iterative or a direct solution, for calculations of the aeroelastic characteristics of both low and high aspect ratio body wing configurations. Good agreement with data from tests or alternate estimates is reached. The direct solution method is considerably faster than the iterative.
