|
if anyone has any experience with building planes or wings or any knowledge about them, you know about the different drag and lift ratios, camber effects etc...(wing)
As another side project my tech teacher and I are going to build a glider. (model) The glider will have a 4 foot wing span with about a 15 percent dihedral or more or any at all.
For the last day I have been playing with modelers trying to find a good wing that will give me lots of lift without lots of camber (camber causes lots of induced drag but at the same time lift) at low speeds that are under 20mph
Since we don't want something that is going to be hard to skin...we are looking for a wing that is a "Hershey bar" configuration (same width and height through the wing like a cessna172 or a bush plane) flat bottom rounded top.
Does anyone know or has heard of a ratio that creates lots of lift at low speeds without a huge AOA or camber. |
