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 in motion in a subsonic flow. The method is based on the most fundamental solution in unsteady flow theory--that of Theodorsen for the oscillating two-dimensional airfoil in an incompressible flow. Definitions are given which relate the aerodynamic forces to the surface deflections. The AICs are derived from strip theory considering the airfoil to have the three degrees of freedom pitching, plunging, and control surface rotation. The Aerospace IBM 7090 Computer Program No. HM07 provides the AICs in printed and optional punched-card output formats. The program capacity is 25 surface strips and 50 values of reduced velocity.
