[6]
● Material:
○ Prop: “The steel-shank core is wrapped in carbon composite material and trimmed
with a nickel-cobalt leading edge with a mesh erosion screen to protect the blades
from foreign-object debris” [6]
○ Fuselage: Al alloy and fiberglass. [7]
● Fuselage: “Most of the fuselage also is a conventional semi-monocoque, high-
strength aluminum alloy structure, with the exception of the forward nose cowl shell
made from aluminum and fiberglass. Skins are flush riveted in areas exposed to the
slipstream. A steel tube assembly, forward of the pressure vessel, supports the engine
and nose landing gear.” [7]
● Wings: “The M600’s new semi-monocoque aluminum wing actually dates back to a
1979 airfoil designed by Robert J. McGhee and William D. Beasley at NASA’s
Langley Research Center. Their MS(1)-0313 (medium-speed, 13% thickness-to-chord
ratio at 37.5% chord) airfoil blends the desirable high-lift characteristics of an earlier
low-speed general aviation airfoil with some of the rooftop pressure distribution,
turbulent boundary layer characteristics of low-drag high-speed airfoils. The result is
an airfoil that has improved maximum lift coefficient and stall behavior
characteristics with a relatively low drag rise up to Mach 0.72, well above the design
speed of the M600. It’s also comparatively immune to performance degradation
caused by leading edge contamination.” “For the M600, Piper modified the baseline
airfoil to have 17% thickness at the root, tapering to 13% at the tip. The aspect ratio is
8.5:1, taper ratio is 0.4:1, geometric twist is 3 deg. and dihedral is 3 deg. Compared to
the NACA 23000 series airfoils used for the Meridian, the M600’s wing is thicker,
but it has better lift-to-drag characteristics at cruise speed as well as even more benign
stall characteristics. The increased thickness not only increases internal volume
available for fuel, it also makes the spars and ribs taller and thinner, thereby reducing
structural weight.” [7]
● Spar: “The wing has forward, main and rear spars. Many of the spar and rib
components are single-piece machinings. Span-wise stringers are bonded to the wing
skins to increase stiffness. Conventional mechanical fasteners, such as rivets and Hi-
Lok fittings, are used to assemble the wing. Right and left wing halves are joined at
the root and then the entire wing assembly is fastened to the fuselage with torque and
shear fittings.” [7]
● Tail: Conventional - determined by images
● Guidlines/ Cerifications: FAA, EASA [8,9]
