HARMONIC GUST AERODYNAMIC INFLUENCE COEFFICIENTS FROM INCOMPRESSIBLE STRIP THEORY: ANALYTICAL DEVELOPMENT AND COMPUTATIONAL PROCEDURE

Abstract

A method is presented for computing the aerodynamic influence coefficients (AICs) for a surface traveling at subsonic speed through an oscillatory gust field. The method is based on a fundamental solution of unsteady flow theory that of Sears for a two-dimensional airfoil traveling through a harmonic gust field in an incompressible fluid. The harmonic gust AICs relate the aerodynamic control point forces to the spanwise variation of the gust amplitude. The Aerospace IBM 7090 Computer Program No. HM02 provides the gust AICs in printed and optional punched-card output formats. The program capacity is 100 surface strips and 100 values of reduced velocity.
