Brief Technical Description
The
Allegro
aircraft is an aerodynamically controlled, two-seat side by side, high-wing
microlight aircraft with the engine at the front and a T-shaped tail. Tricycle landing gear
with
main wheel brakes,
steerable
nose wheel, landing gear suspension by rubber pads.
The aircraft
is made of duralumin
wings and empanage
combined with laminate
fuselage with
a wing
centr
e section/safety cage of
welded
steel tubes.
The wing
is divided in the middle into two halves, both of which are mounted to the
centr
e section
by means of
bolts
and supported by struts. The wing is designed as a rectangle
with composite tips
. The load-bearing part of the wing is represented by a torsion box
consisting of a duralumin spar and the skin made of duralumin sheet. The spar flanges are
made of duralumin L-sections, the spar web is made of duralumin sheet. The
aerofoil section
is
maintained
by ribs made of duralumin sheet.
The ailerons and flaps
are separated.
The tail
is T-shaped, its construction is similar to that of the wing.
The fuselage
is all-laminate, stiffened by means of several ribs. The engine mount and the
nose wheel leg are attached to the front (=”engine”) bulkhead made of laminate sandwich.
The central (=”pilot”) bulkhead serves for attaching adjustable seats, at the rear end of the
fuselage there are two ribs made of laminate sandwich to stiffen the tail fin. The centroplane
is welded together from duralumin tubes, the cockpit is covered by a transparent windshield
made of polycarbonate splinter-proof material.(Beware of fuel staining which damages this
material!!!) Below the seats there is a fuel tank made of laminate, whose inner surface is
covered by a conductive layer of graphite.
The landing gear
is front tricycle undercarriage. The wheels are equipped with brakes
controlled by a mechanical lever located on the control stick. The nose wheel is steerable , it
is connected to the foot control system. The nose wheel has a rubber suspension shackle as
well.
The powerplant
of the aircraft consists of an engine, the type of which is specified in the
”ENGINE LOG BOOK”, and a propeller, the type of which is specified in the ”PROPELLER
LOG BOOK”.
The aircraft has
single control,
the control sticks is situated in the middle between the two
seats. The foot control system consists of two sets of pedals(one set for either of the pilots).
The flaps are actuated by means of an electric switch located at the top between the two
pilots.
