I've acquired a gyroglider that suffered a blade strike, and will be setting about repairing/rebuilding it. It won't be finished this season, but I'm hopeful for next year. It will need a new mast, cheek plates, rotorhead, hub and blades. Most of the rest is intact, and just needs clean-up and inspection.
How does one calculate the correct rotorhead location to make cheekplates on a glider? I know the basics involved in the calculations, but with the people in the seats representing the largest mass, it becomes necessary to estimate the CG of the people themselves while seated, legs extended.
Is a hang test with test plates (testing multiple sets of holes) the only practical way to do this?
Is it necessary to assign some weight to the cable?
All suggestions appreciated. This is a one-off custom gyroglider, so standard Bensen dimensions may not be too useful.
