A monoplane has only one wing airplane, a biplane has two stacked one particular above one other, a tandem wing has two put a person guiding the other.
The wing planform is The form when noticed from earlier mentioned. To become aerodynamically economical, a wing ought to be straight which has a extended span back and forth but have a brief chord (large facet ratio).
Early plane engines had minor power, and lightness was essential. Also, early airfoil sections were quite skinny, and could not have a solid body put in in.
