Design-Build-Fly Competition

An international gathering of 36 student teams competed in the 2007 AIAA Design-Build-Fly competition. In its 11th year, the popular contest challenges student teams to build an unmanned, remote-controlled airplane to satisfy a series of constraints and flying tasks.

The 2007 competition was held on April 20-22 in Tucson, Arizona. The contest required each team's airplane to:

  • Fit in a 2 x 4 x 1.5 foot shipping container
  • Fly a surveillance mission carrying a dummy camera
  • Fly an air sampling mission carrying a dummy air sampling system

The final designs could be classified as:

Massachusetts Institute of Technology (MIT) pushed Oklahoma State University into 2nd, breaking Oklahoma's 3 year winning streak. MIT's entry, OBOSU, rated highly in the Rated Aircraft Cost (RAC) analysis, which favored lightweight designs and short wingspans. Notably the top 2 designs were biplanes. Purdue University finished 3rd with a lifting body design.

Results

  1. Massachusetts Institute of Technology - OBOSU
  2. Oklahoma State University - OSU Orange
  3. Purdue University - Spirit of Amelia
  4. Oklahoma State University - OSU Black
  5. Wichita State University - Shockin’ Surveyor

A key part of many student competitions is a design report and the Design-Build-Fly is no exception. Key required sections are:

  • Conceptual design
  • Preliminary design
  • Detail design

Clearly there is ample scope to use Computer-Aided Engineering (CAE) tools during the preliminary and detail design phases of such a competition. However, the conceptual design phase is currently dominated by ad-hoc analysis using pen, paper, calculator and generic office software (such as Microsoft Excel). Caedium aims to change this state of affairs and open up conceptual design analysis for all.
