An integrated aerodynamic design and analysis procedure for launch vehicles which incorporates engineering prediction methods, historical knowledge, and corporate memory into a knowledge-based system is described. The objective is to provide an economical means to conduct the aerodynamic design and analysis of future launch vehicles to minimize the risk of aerodynamic-induced failures. The method will provide a guide to the aerodynamic-related information required during the conceptual and preliminary design stages. In addition, the user will have access to historical information on similar launch vehicles, the ability to set up geometric characteristics, and a capability to predict preliminary aerodynamics of simple launch vehicles. The method includes a number of searchable databases containing technical references on launch vehicle aerodynamics, engineering experiences and anecdotes on launch vehicle programs of the past, and information about various launch vehicles. The method can be used as a stand-alone tool for traditional design approaches or as an integral part of a multidisciplinary design method. It has archive capability, and it can be updated with new information as desired by the user.
