DESIGN AND CONSTRUCTION
The Schweizer 330 Helicopter is a turbine powered rotary wing
aircraft constructed primarily of aluminum alloy. The main rotor is a
fully articulated three blade system while the tail rotor is a two
bladed semi-rigid type. Power from the turboshaft engine is
transmitted through eight drive belts and two drive shafts to the main
rotor and tail rotor transmissions. An overrunning (one-way) clutch
placed between the engine and main rotor transmission permits free
wheeling of the rotor system during autorotation.
The fuselage (with a central framework consisting of a mast support
structure, one bulkhead and a lateral roll beam) is a semi-monocoque
structure that is divided into three main sections. The forward section
comprises a pilot and passenger compartment and directly aft,
separated by a bulkhead is a faired housing enclosing the fuel cell,
mast, engine air inlet, accessories and drive system. Aft of this
structure is the aft fuselage combining both semi-monocoque and
monocoque construction. The pilot compartment may be equipped
with two or three passenger seats plus the pilot. A canopy of
transparent acrylic panels provides excellent visibility.
The standard 330 requires a minimum crew of one pilot-in-command
seated right side. Dual controls are available as an option. Left side
pilot-in-command is available as an option. The passengers sit
abreast of the pilot with the center seat slightly aft. A bench type
center seat is available to accommodate two passengers (for a total of
three). This option is available only with the left side
pilot-in-command configuration. Seat belts are provided for all
positions. The special trainer version is equipped with three seats and
three sets of controls, with a right seat pilot-in-command.
The instrument panel is located forward of the seats at the aircraft
centerline. The panel incorporates standard flight and engine
instruments in addition to warning and caution lights. The panel also
contains adequate space provisions for various arrangements of
communications and navigation equipment.
Stowage area is provided behind the outboard seats and in front of
the bulkhead.
