The all-metal airframe of EV-97
Eurostar consists of metal stiffeners, frames and duralumin sheet
skin. Parts are mostly joint by pop rivets and by adhesive bonding. Some
of parts, especially those parts non-carrying high loads, are made of
The fuselage is of semi-monocoque
structure consisting of stiffeners and duralumin skin. The fuselage
section is rectangular in the lower part and elliptical in the upper part.
The fin is an integral part of fuselage. The cockpit for two-member crew
is situated in the middle part of the fuselage and is accessible after
folding down the single-part organic glass canopy. The engine compartment
in the front part of fuselage is separated from the passenger compartment
by the fire wall to which the engine mount is attached.
The wing of rectangular shape is of
single spar structure with the auxiliary spar on which ailerons and split
flaps are hinged. Riveting is used to assemble all individual design
parts. Fiberglas wing tips are riveted on the wing ends. At the
customer's wish the airplane can be equipped with the wing folding
mechanism, which enables hangaring with minimum room requirements.
Each half of wing is equipped with the
rectangular aileron. The aileron consists of ribs and skin, creating
cavity. The aileron is hinged on the wing by means of the swivel
throughout its length.
Each half of wing is equipped with the
split flap that takes about two thirds of half span of wing. The
rectangular flap consists of ribs and skin, creating cavity. The flap is
hinged on the wing by means of swivel throughout its length.
Horizontal Tail Unit
Horizontal tail unit, of usual type,
consists of the stabilizer and the elevator with the trim tab. Single spar
structure HTU of rectangular contour is composed of duralumin ribs, spar
and skin. HTU span is 2.5 m, which enables transportation of HTU on the
trailer without its disassembling.
The rectangular stabilizer consists of
ribs and duralumin skin. The stabilizer is attached to the fuselage by
shifting on two pins in the front part and is secured by two bolts in the
The elevator consists of ribs and
duralumin skin. The elevator is hinged on the stabilizer by means of
swivel. The trim tab is hinged on the trailing edge of the elevator by
means of swivel.
The elevator is equipped with one
rectangular trim tab. The trim tab consists of duralumin skin creating
cavity. The trim tab makes up about two thirds of HTU and is hinged on the
elevator by means of swivel throughout its length.
Vertical Tail Unit
The trapezoidal VTU of rectangular
contour consists of the fin and the rudder.
The fin part of VTU is an integral part
of the fuselage. Its structure is composed of two duralumin spars, root
rib, end rib and skin. The upper part of fin is closed by the laminate
cover on which the anti-collision beacon can be installed. The fairing
between the fuselage and the tail unit is made by the fibreglass cover.
The trapezoidal rudder is composed of
the duralumin spar, skin, upper and lower rib. The rudder is attached to
the fin by means of two hinges. The upper part of the rudder is closed by
the fibreglass wing tip.
