About Design/Build/Fly
The 2024-2025 Design/Build/Fly Competition will celebrate its 29th year. Started in 1996 by the AIAA Applied Aerodynamics, Aircraft Design, Design Engineering and Flight Test Technical Committees as an opportunity for university students to apply real-world aircraft design experience by giving them the opportunity to validate their analytic studies.
Student teams will design, fabricate, and demonstrate the flight capabilities of an unmanned, electric powered, radio-controlled aircraft which can best meet the specified mission profile. The goal is a balanced design possessing good demonstrated flight handling qualities and practical and affordable manufacturing requirements while providing a high vehicle performance.
To encourage innovation and maintain a fresh design challenge for each new year’s participants, the design requirements and performance objective will be updated for each new contest year. The changes will provide new design requirements and opportunities, while allowing for application of technology developed by the teams from prior years.
