Aerodynamic Preliminary Analysis System II: Part II---User''s Manual

An aerodynamic analysis system based on linear potential theory at subsonic/supersonic speed and newtonian impact type finite element solutions at hypersonic conditions is described. Three dimensional configurations having multiple non-planar surfaces of arbitrary planform and bodies of non-circular contour may be analyzed. Static, rotary and control longitudinal and lateral directional characteristics may be generated. The analysis has been implemented on a time sharing system in conjunction with an input tablet digitizer and an interactive graphics input/output display and editing terminal to maximize its responsiveness to the preliminary analysis problem. CDC 175 computational time of 45 CPU seconds/Mach number at subsonic-supersonic speeds and 1 cpu second/Mach number/altitude at hypersonic conditions for a typical simulation indicates that the program provides an efficient analysis tool for systematically performing various aerodynamic configuration tradeoff and evaluation studies.
