Air vehicle technology modeling and simulation /

The aircraft design process is a complex, highly iterative, time-consuming process that contributes significantly to the overall engineering cost. Aircraft specifications, including performance, weight, cost, and other aspects, must be addressed to create an effective design. The multidisciplinary nature of the engineering process, which includes design, analysis, and manufacturing, follows a regimented path that is initiated by preliminary design, evolves into a preliminary design, and is followed by a detailed design for production. Many critical design decisions are made at the conceptual level where the least amount of information is available to assist in the design evaluation and tradeoffs. The objective of this effort is the development of a comprehensive design environment for modeling and simulating the aircraft systems, seamlessly integrating different engineering processes. The system architecture will support a single underlying object-oriented architecture with demand-driven computation and dependency tracking that allows information to feed forward and backward among various engineering processes as the design evolves.Photocopy."Final Report: July 28, 1997 -- July 1, 1998.""March 1998."Includes bibliographic references (page 21).The aircraft design process is a complex, highly iterative, time-consuming process that contributes significantly to the overall engineering cost.
