Description

Our team successfully took 30th place out of over 100 international teams at our first participation in the “DBF 2019 – Design, Build and Fly Competition” in Arizona, USA.

What Were The Rules Of The Competition?

  1. Successful takeoff on a 3m long ramp with a 5-degree gradient.
  2. Installing folding wings.
  3. Length measurement of max. 60cm (from the nose to the rearmost wheel).
  4. When folded, the model is to be pushed through a 90cm wide and 60cm high tunnel.
  5. Automatic start preparation via a switch (automatically unfolds and locks).
  6. No use of Lithium-ion and Lithium-polymer batteries allowed.
  7. Successfully passing the so-called “ wingtip test” (This means the model must withstand being lifted at both wingtips).
  8. The lift must be generated via the wings (higher density than air).

What Were The Missions and What Were Points Awarded For?

  1. Ground mission (max. 1 point): The radar and payloads should be attached to the model as quickly as possible.
  2. Flight mission (1 point): The flying object should take off and complete its circuits.
  3. Flight mission (max. 2 points): A radar (in this case only a dummy) should be placed on the model and switched on and off during the flight.
  4. Flight mission (2 points plus the number of payloads dropped ): As many payloads as possible should be dropped in a 10-minute flight window . Only one payload may be dropped per circuit. These must be attached under the wing and fuselage.

In addition, a “Design Report” is submitted, which can bring in up to 100 points. The following applies to the total score: GP = Design Report points x sum of all four missions.
