Cirrus Design
SR22
The G3 Wing is constructed in a conventional spar, rib, and shear
section arrangement. The upper and lower skins are bonded to the
spar, ribs, and aft shear web forming a torsion box that carries all of
the wing bending and torsion loads. The rear shear webs are similar in
construction but do not carry through the fuselage. The main spar is
laminated epoxy/carbon fiber in a C-section, and is continuous from
wing tip to wing tip. The wing spar passes under the fuselage below
the two front seats and is attached to the fuselage in two locations. Lift
and landing loads are carried by the single carry-through spar, plus a
pair of rear shear webs (one on each wing) attached to the fuselage.
G3 Wing geometry is slightly changed with an 1° increase in dihedral
which allows for the elimination of the aileron-rudder interconnect
system.
The CG Envelope (Center of Gravity Envelope) is expanded to allow
for slightly more forward loading at higher gross weights.
The main landing gear is moved slightly inboard and the strut angle
increased to achieve an increase in airplane height of 1.5 inches.
The ice protection system's glycol tank is moved from the fuselage to
an integral tank on the left wing and the porous panels are lengthened
to cover the entire leading edge of the wing.
Other G3 Wing updates include:
• Increased fuel capacity,
• wing tip with integral, leading edge recognition lights.
• relocation of the fresh air inlets to the engine cowl and related
environmental system changes,
• improved trailing edge aerodynamics
• improved wing root fairings,
• relocation of the stall warning port.
