INTRODUCTION

Section 7 describes the different systems specific to the Sirius. Some equipment
described in this section may be optional and will not apply to all serial numbers.

AIRFRAME

The Sirius is a carbon-composite, high-wing, single-engine, two-seat LSA
aircraft. The fuselage is laminated and, in some areas, is sandwiched foam that
allows for good structural integrity at a nominal weight. The largest sections of
this material are the fuselage section, wings, rudder, and the horizontal stabilizer
with the elevator.
The cabin compartment is arranged as a side-by-side two-seat configuration with
flight controls for both crew positions. The cabin windows are constructed of
Plexiglas. The cabin doors are framed with fiberglass and pivot on two overhead
hinges, each door is fastened by a spring latch at the bottom and two manually
operated lock pins at the forward and aft center of each door jamb.
The engine is fastened to a six point rubber-damped cradle mount that is secured
at the stainless steel firewall by four attach points with rated steel bolts.
The wings are attached to the fuselage at two spar carry-through locations.
Structural bolts assume all torsion and shear loads at the fuselage. The wing
strut is an integral part of the triangulation load carrying capacity of the wing spar.
The hinged ailerons and normal flaps are affixed to the aft spar of each wing.
The flaps are attached by five hinges that allow the flap to rotate down to change
the lift and drag characteristics of the wing when extended and align with the
wing chord when retracted.
The empennage section is made up of the vertical stabilizer with the rudder and
the horizontal stabilizer with the elevator. The vertical stabilizer is molded as a
part of the fuselage section. The rudder is attached to the vertical stabilizer by
slide-on pins and a rod that runs down the leading edge of the rudder, through
ball bearing races, which connects to the rudder control cables. The horizontal
stabilizer is attached to the fuselage section by two horizontal guide pins and a
single vertical steel bolt. The elevator is affixed to the horizontal stabilizer by five
bolted pivot points.
