Abstract
One of the tasks encountered in aerospace vehicle design synthesis is the analysis of the actual geometric configuration. The proper relationships between body, wing, and tail sizes are necessary to maintain aerodynamic performance requirements. These geometric data are, in general, interactive one upon the others.
McDonnell Douglas Corporation has investigated various methods by which these data can be analyzed to establish the required vehicle geometric configuration. Very specific uses have been found for each method examined often with only subtle differences between the results produced by different methods.
From the experience gained in various sizing programs, several conclusions have been reached. There are multiple approaches to the geometry definition and sizing. Any weight-sizing must tailor the geometry to interface with the aero-design requirements. The time available to produce the computer program and the computer capacity many times demand that simplified geometries be adequate.
