Calculation of Component Forces and Moments of Arbitrarily Banked Cruciform Missiles with Control Deflections.
Abstract
This report describes the development of a preliminary version of a single comprehensive code for the engineering calculation of all missile component aerodynamic forces and moments, except minimum drag, for angles of attack up to the unsteady regime. The engineering method to be described in this report is composed of five basic procedures: (1) computation of forces and moments, with no external vortices present, for individual fins in the presence of a body at arbitrary angle of attack and bank angle with control deflections; (2) computation of forces and moments induced on individual fins due to the presence of external vortices; (3) calculation, using an empirical method, of the strengths and positions of body vortices generated upstream of the first set of fins; (4) computation, using a vortex tracking method, of the strengths and positions of vortices between the first and second sets of fins; and (5) determination of body forces and moments due to the presence of the fins and vortices.
