| Summary: | 碩士 === 逢甲大學 === 機械工程學系 === 88 === Develop a precise and efficiency aircraft design programs are powerful tools for shorten the aircraft design working-hour. Particularly for the process of optimal design and trade study, computer programs offer high-speed and convenient design processes. In this article, programs for the aircraft conceptual design processes will be established.
The design process used by this article is base on methods of Raymer、Roskam、Nicolai, and use modules for every design units to buildup the aircraft conceptual design program, CAACD (Computer Aided Aircraft Conceptual Design).Linear regression method was utilized for simplify to inquire about diagrams. And use this concept to buildup the database for program to be suitable for use of more type of aircraft. The program computes aircraft’s static stability and draw the performance diagrams, and by the use of vision design concept, the designed components planform can be drew by input design parameters, this offer intuition design reference.
To the support of AASRC (Aeronautical and Astronautical Society of Republic of China) aircraft design competition, we target remote pilot patrol aircraft to be our objective. Preliminary design and manufacture work offer the program to test and verify, and the test of wind tunnel model and propulsion system offer the data for compare with design. The result proved that the program offer more precise and efficient advantages, and could be use for trade study and optimal design for aircraft conceptual design.
