Massachusetts Institute of Technology. Flight Transportation Laboratory (Formally 'Multi-valued Output and External Code Interface Capability') This report reproduces a thesis submitted on January 16, 1987, to the Department of Aeronautics and Astronautics of the Massachusetts Institute of Technology in partial fulfillment of the requirements for the degree of Master of Science Includes bibliographical references (p. 143-[144]) The problems of the integration of engineering models in computer-aided preliminary design are reviewed. This paper details the research, development, and testing of modifications to Paper Airplane, a LISP-based computer program, designed to address these integration problems. Paper Airplane integrates engineering models by treating them like a set of simultaneous non-linear functions and numerically solving for them as such. The original version of Paper Airplane could only handle engineering models represented by single equations and simple LISP functions; that is, multiple-input single-output (MISO) functions. The modifications to Paper Airplane were to allow it to handle engineering models represented as complex LISP functions and external computer programs as well; that is, multiple-input multiple-output (MIMO) functions. The research was divided into three tasks: (1) to get Paper Airplane to communicate with an external computer program (without changing the computer program), (2) to get Paper Airplane to numerically solve a non-linear MIMO function, and (3) to get Paper Airplane to numerically solve a set of simultaneous non-linear functions made up of MISO and MIMO functions. 2012-01-06T22:06:27Z 2012-01-06T22:06:27Z c1987 Technical Report 16877776 http://hdl.handle.net/1721.1/68067 FTL report (Massachusetts Institute of Technology.
