OF THE AIRPLANE AND ITS SYSTEMS
7.1
THE AIRPLANE
The Cherokee
Turbo Arrow III
is a single engine, retractable
landing gear, all metal airplane. It has
seating for up
to
four
occupants,
a 200 pound luggage compartment, and a
turbocharged
200 HP engine.
7.3 AIRFRAME
With the exception
of
the
steel engine mount, the landing gear, miscellaneous steel parts,
the
cowling,
and
the
lightweight
plastic extremities
(tips
of wings,
tail
fin, rudder and stabilator),
the basic airframe is of
aluminum alloy. Aerobatics are prohibited in this airplane since the structure is not designed for aerobatic
loads.
The fuselage is a semi-monocoque structure.
There is a front door on
the right side. A cargo door is
installed aft of
the rear seat.
The wing is of a conventional design semi-tapered and employs a laminar flow NACA 652-415
airfoil
section. The
main spar is located at approximately 40% of
the
chord aft of
the leading edge. The
wings
are
attached
to
the
fuselage by the insertion of the
butt ends of
the spar into a spar box carry-through,
which is
an integral part of the fuselage structure. The bolting
of
the spar ends into
the
spar
box carry-through
structure,
which is located under the
aft seats, provides in effect a continuous
main spar. The wings are also
attached fore and aft of
the
main spar by an auxiliary front spar and a rear spar.
The rear spar, in addition
to
taking torque
and drag
loads, provides a mount for
flaps and ailerons. The four-position wing
flaps
are
mechanically
controlled
by
a handle located between the front seats. When fully retracted,
the right flap
locks into place
to
provide a step for cabin entry. Each wing contains one fuel
tank.
A
vertical stabilizer, an all-movable horizontal stabilator,
and a rudder make up the
empennage.
The
stabilator incorporates an anti-servo tab
which improves longitudinal
stability and provides longitudinal
trim.
This tab moves in the
same
direction
as
the
stabilator,
but with increased
travel.
