Design Build Fly 1
2025
Abstract
The American Institute of Aeronautics and Astronautics (AIAA) hosts a competition every year called Design/Build/Fly (DBF). The objective of this competition is to design, build and fly a product that is outlined in the rules for a given year. For 2024-2025, the goal was to make a radio-controlled airplane and autonomous glider. Both the aircraft and X-1 themed glider were to be built to the limitations and specifications outlined by AIAA, while also excelling in the separate flight missions, which are themed around the X-1 supersonic flight program. The aircraft was also built to meet FAA regulations for a lightweight aircraft, one that does not exceed 55 pounds.
Project Details
There was an extensive list of constraints and rules that had to be followed for this project. The airplane must be fixed-wing and manually radio-controlled, with no autopilots or flight controllers allowed, although flight stabilization systems were permitted. Takeoff must be powered solely by onboard electric propulsion using commercially available brushed or brushless motors and propellers. The total aircraft weight with payload must remain under 55 pounds to meet AMA regulations, and pilots must be AMA members. Proof of prior flight is required through video, and the aircraft must match the configuration submitted in the design report, with only minor performance tweaks allowed. The RC system must have an external, easily accessible switch separate from the propulsion arming system.
Battery systems must use one pack per propulsion unit, with no series or parallel connections, and all packs must be identical if multiples are used. Only one battery chemistry is allowed for propulsion, and once approved at tech inspection, it must be used throughout the competition. Each battery pack must be Commercial-Off-The-Shelf (COTS), properly labeled, under 100 Watt-hours, and use fully insulated connectors. Lithium batteries must be stored and charged in commercial battery bags, and batteries cannot be changed or charged during a mission.
Project Objective
Our objective for this project is to design, build, and operate a lightweight, fixed-wing aircraft that fully complies with all competition regulations, including AIAA and FAA requirements. We aim to create an efficient design that prioritizes both safety and performance, while demonstrating strong technical skills in aircraft development and flight operations. Additionally, we seek to contribute to the team's success through effective collaboration, problem-solving, and attention to detail during all phases of the project.
Mission Needs
Design and Build an RC aircraft to the specifications and limitations outlined by AIAA for entry into the 2025 Design/Build/Fly competition.
