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.
