A digital computer program, MASMOD Mass Model, which is capable of generating both the mass and aerodynamic aircraft models required for the VIBRA - 4 Vehicle Inelastic Bending Response Analysis computer program is presented in this report. MASMOD employs basic data given for an aircraft to generate either individual component or entire aircraft lumped-mass and aerodynamic models, three-dimensional influence coefficients, and mode shapes and frequencies. Additionally, MASMOD has the capability of plotting the formulated mass and aerodynamic models as well as the components relative bending and torsion in each vibrational mode calculated by the program.
