In this episode, Josh and Josh show you how we built our 2016 Boston Flugtag glider aircraft!
We built this plane in about two weeks with a budget of $500. We applied the same structural principles used in models and full-scale planes to create the wing.
We used a box spar with a piece of wood on the top and bottom and shear webbing in the middle. To give it more rigidity, we used half-inch foam ribs in the middle and put everything together using Gorilla Glue and Super 77.
Josh B. designed the ribs in DevWing and laser-cut a rib template. Then Chad Lewis used that template to cut out all the ribs by hand. We discovered that the foam ribs were shaky, so we used extreme packing tape across the wing frame to make it sturdier.
We added the covering a section at a time, sealing each one before adding the next section. After everything was mounted, we used a heat gun to remove the wrinkles. One part of the wing is under compression and the other part is under tension, so the wing flaps fly together and bolt it.
We made the bottom spar a little longer and drilled the main plates on the spar to create the dihedral.
Our functioning rudder and elevator were made with 3/4-inch foam covered with plywood, which made them very sturdy. We also flipped the dorsal so it was on the bottom instead of the top the day before the competition.
Thank you to Josh Scott, Chad Lewis, Bob Parmalee, Chad Nowak, and everyone else who helped create our Flugtag aircraft.
And a huge thanks to you, our community, for your incredible support and making this possible! We couldn’t have done it without you!
