![]() Special thanks go to Cessna Aircraft for hosting the flyoff this year. Thanks also go to the Corporate Sponsors: the Raytheon Missile Systems, Cessna Aircraft, and the AIAA Foundation for their financial support. These volunteers collectively set the rules for the contest, publicize the event, gather entries, judge the written reports, and organize the flyoff. We owe our thanks for the success of the DBF competition to the efforts of many volunteers from Cessna Aircraft, Raytheon Missile Systems, the Naval Research Lab, and the AIAA sponsoring technical committees: Applied Aerodynamics, Aircraft Design, Flight Test, and Design Engineering. ![]() The complete standings are listed in the table below. The top report score of 98% was achieved by Wichita State University Team AeroShock, and the lowest System Weight was built by Massachusetts Institute of Technology Team Cardinal. UT Austin Team Hornworks scored second, and OSU Team Orange was third. Cons: This a free software with a lot of versions and constantly updated, you have to be. OSU Team Black scored first place with an excellent written report score, very low System Weight, and two of the top three flight scores. Librecad offer the same amount of tools that a private software, with a very more simple interphase you can draw, make measures, add text, put details on the design and of course print, you can also save on PDF version your files to share when you want. More details can be found at the competition website: The top places were taken by teams from two universities: Oklahoma State and U. As usual, the total score is the product of the flight score and written report score. Total flight score was the sum of the delivery flight score plus up to two payload flight scores. The payload flight score was determined by the inverted product of the loading time, battery weight, and empty weight. The airplane then had to fly two laps of the course to make the score valid. For the payload flights, teams were assigned a payload manifest determined at random, and the payload loading was timed. The flight score was determined by the number of laps flown in a five minute period, divided by the battery pack weight for that flight. A delivery flight was first required, where the airplane was flown with no payload. The primary design objective for this year was to accommodate a random payload combination composed of passengers (1/2 liter water bottles) and cargo pallets (1/2 size bricks). A historical perspective of participation is shown below. In almost every respect, the quality of the teams, their readiness to compete, and the execution of the flights was better than in any past flyoff. Of the 166 official flight attempts, 55 resulted in a valid score. Near ideal weather allowed for non-stop flights to be conducted each day. Approximately 600 students, faculty, and guests were present. At least 51 teams attended the flyoff, 47 of which completed the technical inspection. A total of 60 teams submitted written reports to be judged. This was the 12 th year the competition was held, and participation continued to increase from past years. The 2008 Cessna/Raytheon Missile Systems Design/Build/Fly Competition Flyoff was held at Cessna Field in Wichita, KS on the weekend of April 18-20, 2008.
