Paper Airplane user's manual : version four

Abstract

Preface: This document provides the user with a step-by-step guide to using Paper Airplane, Version IV. Although this program can be used to design any system (once given the proper set of design equations), this manual will use as a running example the design of an executive transport jet, the AM410-Laser. This design was originally done by the author using manual calculations; where appropriate, comparisons will be made between the two methods. This manual contains the following conventions for displaying examples: * Bold sans-serif text such as this will represent user input requirements or options that you should enter exactly as shown - including upper and lower case. o Italic sans-serif text such as this will represent user input requirements or options that you need to specify. o Thin curly-brackets surrounding a list of user input separated by commas: {. } will represent a choice of requirements. "Thin square-brackets surrounding user input: [...] will represent optional input." Thin square-brackets surrounding a list of user input separated by commas: [......] will represent a choice of options. " Typewriter-style text such as this will represent the response from Paper Airplane or the system. Paper Airplane Version IV runs under NIL release 329 or above on the DEC VAX family of processors under the VMS operating system. The NIL Lisp language system is available from M.I.T.'s Laboratory for Computer Science, 545 Technology Square, Cambridge MA 02139. Paper Airplane also runs under Zeta LISP on the Texas Instruments Explorer. Paper Airplane requires a VT100-compatible terminal, equipped with a keyboard containing arrow keys and a programmable keypad with PF-keys as well as numbers. Version IV of Paper Airplane contains a substantial number of improvements over the last documented release. In particular: 1. Much faster convergence on design point solutions. 2. Capability to use multiple-input multiple-output design functions along with multiple input single-output design functions. 3. Capability to use non-LISP based external computer programs as design functions (on VAX only). 4. An enhanced Design Function Exerciser. 5. Pre-defined table-lookup auxiliary functions. 6. Addition of a Library to store design variables and design functions from which design sets can be made. Paper Airplane is distributed with the understanding that no claims are made as to the use or performance of this system. Paper Airplane is released for evaluation, stimulation, and exchange of ideas only.
