GG HANG GLIDER

Figure 1. Basic design of the GG Hang Glider, a 18 ft standard Rogallo with 80º nose angle.
This drawing was generated using the program LE Hang Gliding version 0.12 with the data data.txt and the result file glider.dxf

This project is under construction by Gilberto Guitarte in North Carolina (USA). The goal is design and build a very simple hang glider, "Rogallo" type, and do some tests, only for fun, in the same dunes of Kitty Hawk where Rogallo and the Wright brothers did their tests. The design is made on the basis of data based in the project SPS2008 and some original plans from the 70's. Soon more data will be published. Now you can see some photos of the construction process.

GG Update 2021-08-08: "Last Monday I moved the project to the farm of the aforementioned friend and on Thursday afternoon I was able to advance a little, (see attached power point)
slide the sail over the leading edges and also make the keel pocket. It begins to encourage me to continue to be able to see the shape of the Rogallo.
In two more weeks - if I can- I return to the farm to continue to cut and assemble all the 3/32" SS tensioning cables."

LAB NOTE: Build a hang glider at home is a very complicated task (even "Rogallo" type), and requires many hours of work. Previous experience is required, and very inventive. As always remember that: The free flight implies risks that can only be known and they can be controled with a suitable formation on the part of a recognized school. Not test wings without knowing their functioning. The construction and test of experimental wings without certifying requires deep knowledge of what is being made.
