Our next major project for our LeGrand is the production of a new main wing element. We’re aiming for around 6 square feet of wing for the rear array—we’re allowed 8 total square feet. We figure the best way to do that is to make a 12x55-inch main element and add a secondary (and possibly tertiary) element to bring the total chord into the 15-inch range.
We found a source for an inexpensive foam wing core, and we’re using composites from The Composite Store. Look for more information on this process in an upcoming GRM magazine article; the pictures here are an overview of the project. We performed the work in the materials lab for the Aviation Maintenance Science department of Embry Riddle Aeronautical University, but the work could be duplicated in any area with large horizontal surfaces.
