In
aviation, a
multiplane is a fixed-wing aircraft-configuration featuring multiple wing planes. The wing planes may be stacked one above another, or one behind another, or both in combination. Types having a small number of planes have specific names and are not usually described as multiplanes:
- Biplane - two wings stacked one above the other
- Triplane - three wings stacked one above another
- Quadruplane- four stacked wings
- Tandem wing - two main planes, one behind the other. The tandem triple or tandem triplet configuration has three lifting surfaces one behind another.
