Abstract : There are two basic operations required to compute the dispersion due to thrust misalignment. The first operation is insertion of the proper data into the 6 degree of freedom computer program. The second is the conversion of the computer output to an impact point deviation. Data are entered into the computer program by means of two constants. The first constant, denoted A for convenience, is multiplied by the thrust to give the normal component of thrust in some selected angular plane. This angular plane is located with respect to the body axis system of the vehicle and generally is coincident with either the pitch or yaw plane. The second constant, denoted B, is multiplied by the thrust to give the moment about the vehicle center of gravity in the plane of A. Physically, B represents the product of A and the distance along the longitudinal axis from the nozzle exit plane to the missile center of gravity. (Author)
