Conventional materials for an unconventional airplane.

Titanium, aluminum, Carbon Fiber...


The AS2's composite airframe structures will be conventional by today’s standards. With military and civilian jets (including the all-composite Boeing 787) using composite structures extensively, their properties are now well understood and their manufacture routine.

The AS2 will use carbon fiber for wings, fuselage, empennage (the tail section) and engine nacelles. Carbon fiber is especially well suited for the wing structure, which requires lightness, smoothness, conformity to very precise contours, and, most importantly, high stiffness. The wing structure will resemble a modern fighter jet’s wing as opposed to today’s long, flexible, high-aspect-ratio airliner wings.

The leading edge of the wing will be made of titanium alloy to resist erosion, and some internal fittings will be fabricated from aluminum, steel and titanium, similar to what would be found in other modern jets.

Super lightweight, very smooth and extremely strong, carbon fiber is the material used in today's jet fighters.
