Computer Aided Parametric Analysis for General Aviation Aircraft

The development of a computer model designed to aid in the preliminary design analysis of general aviation aircraft is described. This model has interrelated in computerized form, the technical disciplines of configuration design, aerodynamics, propulsion, structural weight and balance, and economics to provide a useful engineering tool for identifying critical design parameters and promising advanced technologies. Both analysis of a given airplane and the design of an airplane to meet specified criteria can be achieved with various levels of input and synthesis complexity. Results of a typical parametric analysis are presented for a turbine-powered, six-place configuration.
