A flight mechanics model for performance calculations and relationships between flight vehicle and ramjet engine with subsonic combustion relative to the flight path is described. Performance calculation for a ramjet engine initially required determination of the burst demand throughout the flight path. This is the objective of a flight mechanics computer model. The computer model described is based on the assumption of equilibrium of forces at the center of gravity of the flight vehicle. A further input is an aerodynamic model of the flight vehicle. The flight path is input with a statement of the flight profile, acceleration on flight direction and turning acceleration. The interaction between flight vehicles and ramjet engines in conjunction with the flight path is considered. The influencing variables in the consumption relating to mission phases are described. The role of the angle of incidence and the significance of the design are explained. Interactions are described on the basis of modification of parameters for flight path data (ram pressure, acceleration in flight direction and turning acceleration).
