Aero Terms Unit 2 Puzzle 2.1

2. Layers A thin layer of air next to the surface of an airfoil which shows a reduction in speed due to the air's viscosity.
3. In/ Wash Out A built in twist in the wing so that the trailing edge at the wingtip is raised (Wash out) or lowered (Wash in). This significantly affects the slow flight and stall characteristics of the wing.
4. of Interia A mathematical property of a cross section that is concerned with a surface area and how that area is distributed about a centroidal axis.
6. The ability of a material to resist deflection or stretching.
8. Any alteration of shape or dimensions of a body caused by stresses, thermal expansion or contraction, chemical or metallurgical transformations, or shrinkage and expansions due to moisture change.
9. Forward-acting force which opposes drag and propels the aircraft through the air.
10. Stabalizer A structure that creates up and down forces at the tail to keep the fuselage aligned in pitch with the relative wind. The structure itself is horizontal while the forces it creates are vertical.
11. Span The distance from wing tip to wing tip of a wing planform.

1. area A surface or shape exposed by making a straight cut through something at right angles to the axis.
5. A material made of multiple layers of fibers held together with a matrix.
6. A device for making, breaking, or changing the connections in an electrical circuit.
7. Any of the long rod-shaped photosensitive receptors in the retina that are responsive to faint light.
