Aircraft Conceptual Design Software
1. A.A.A (for Windows)• Developed in University of Kansas
• Based on “Airplane Design” Part I ~ Part VII.
2. RDS-Student (DOS program)• Based on “Aircraft Design: A Conceptual approach”
• Suitable for fighter aircraft design.
3. Piano for Windows• Suitable for commercial aircraft design.
• Plenty of data.
