Description

Figure 1 shows the flap structure. Each flap has the following components:
A. Top Shell
The top shell has inner and outer GFRP skins. The skins bond to a rigid plastic foam core. Carbon
cloth gives extra strength and stiffness in the outer skin.
B. Bottom Shell
The bottom shell has inner and outer GFRP skins. The skins bond to a rigid plastic foam core.
Carbon cloth gives extra strength and stiffness in the outer skin.
C. End Ribs
The end ribs are rigid carbon moldings. They bond to the top and bottom shells.
D. Flap Horn
The flap horn is aluminum alloy. Bolts and nuts attach the flap horn to the flap.
E. Flap Hinges
Each flap has 3 hinges (and the flap horn). The flap hinges are stainless steel. Bolts attach the flap
hinges to the flap.
