Abstract : A set of six fast computer codes, in FORTRAN, used in the preliminary design of projectiles is assembled. The codes are structured to form a closed-loop cycle for fast aerodynamic applications. The closed-loop cycle signifies the collection of codes to perform: (1) physical properties calculations, (2) aerodynamic predictions; and (3) simple trajectory calculations. Six codes are assembled, four of which are for aerodynamic predictions. Of the four codes, two are for general configurations and applications, namely the Missile DATCOM and the WSWC-AP codes. The other two codes, which are for specialized configurations and calculations are the McDrag and FINNER (Donovan's) codes. The sixth code is for a simplified three degrees of freedom trajectory code(x,y and spin). Six interactive programs were written and developed to aid the nonfrequent or first-time user's of these codes. Lists and illustrations of the required input of each code are provided. These lists are based on the input actually required by the codes as described in their corresponding user's manuals. Each lists is also followed by an example with a projectile configuration, dimensions and other specific data. The examples are set to correspond exactly to the list of input of each code. The provided lists and examples can be utilized as a user's reference for the six codes. Also each code can be used separately or in a complete design cycle. The interactive codes were tested and closed-loop design cycles were actually performed for proofing the interactive codes.
