DESCRIPTION AND OPERATION
OF
THE
AIRPLANE AND
ITS
SYSTEMS
7.1
THE
AIRPLANE
The Warrior II is a single-engine, fixed gear monoplane
of
all metal
construction with low semi-tapered wings.
It
has four place seating and a
baggage capacity
of
two hundred pounds.
7.3
AIRFRAME
The primary structure, with the
exception
of
the steel tube
engine
mount, steel landing gear struts and isolated areas, is
of
aluminum alloy
construction. Lightweight plastics are used extensively in the extremities -
the wing tips, the engine cowling, etc.
- and in nonstructural components
throughout the airplane.
The fuselage is a conventional semi-monocoque structure.
On the right
side
of
the airplane is a cabin door for entrance and exit. A baggage door
is
installed aft
of
the rear seat.
The wing is
of
a conventional, semi-tapered design incorporating a
laminar flow,
NACA
652415, airfoil
section.
The
cantilever
wings
are
attached to each side
of
the fuselage by insertion
of
the butt ends
of
the main
spars into a spar box carry-through which is an integral part
of
the fuselage
structure. The spar box carry-through structure, located under the rear seat,
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.
