Abstract:

A procedure for computing the propulsive and aerodynamic forces and moments acting on vehicles propelled by air-breathing propulsion systems is presented. Equations describing the computation of these forces and moments for the three main phases of flight encountered by vehicles with air-breathing propulsion systems are derived. Using the derivations and procedures outlined in this document will allow the propulsive and aerodynamic forces and moments to be computed independently by the relevant specialists, with the confidence that all forces and moments affecting the flight of the vehicle are properly accounted for. These derivations and procedures have been made as general as possible, and should be applicable to most situations or vehicle types.
