FLAGSHIP COMPETITION

Design/Build/Fly (DBF)

Now in its fourth decade, DBF challenges student teams to design, fabricate, and fly an uncrewed, electric-powered, radio-controlled aircraft against a mission profile that changes every year. Teams are judged on a written design report and flight performance at the fly-off.

It's as close as most undergrads get to a full aircraft development cycle: requirements, trade studies, structural design, manufacturing, integration, and flight test, all against a hard deadline and a live audience of judges.

  1. Assemble your teamAerodynamics, structures, propulsion, controls, manufacturing — every role matters.
  2. Study this year's missionRules and mission requirements are released in the fall and change every year.
  3. Submit your design reportA written proposal decides which teams advance toward the fly-off.
  4. Compete at the fly-offTest flight handling, payload capacity, and manufacturing quality against teams worldwide.

Beyond DBF

DBF isn't the only way to compete. AIAA runs a wider slate of competitions students can get involved with.

AIAA Design Competitions

Paper design competitions modeled on real industry Requests for Proposal (RFPs) — a good fit if you'd rather focus on the engineering write-up than the physical build. They run across several categories:

Aircraft Design (Team & Individual) · Missile Systems Design · Space Design · Engine Design

CanSat

A design-build-launch challenge where teams build a satellite-like payload sized to fit inside a soft-drink can, then launch, recover, and analyze it against a mission profile — run jointly with the American Astronautical Society.
