The ViS ViS-3 is a high-wing, single-engine ultralight aircraft originating from Ukraine. Its production model carries the designation KhAZ-30 (ХАЗ-30).

Design and development

The ViS-3 features a two-seat configuration with side-by-side seating and is a conventionally arranged high-wing ultralight monoplane. Its maiden flight occurred on 8 October 2006, initiating a flight testing phase that evolved through the modified ViS-5 to the production KhAZ-30 (ХАЗ-30) manufactured by the Kharkiv State Aviation Plant, which was publicly unveiled on 22 May 2012. Throughout its development, subtle yet important modifications were introduced, notably the elimination of forward wing sweep combined with the incorporation of wing dihedral and flaps. The airframe is predominantly metal in construction, while the wings are covered with fabric. These wings exhibit straight edges with a uniform chord and are supported by a single streamlined strut on each side, angled forward from the lower fuselage to the wing.

The fuselage presents a relatively shallow profile, encompassing an elongated cabin glazed extensively both forward and aft of the wing, including above and on the sides. Power is provided by a 73.5 kW (98.6 hp) Rotax 912 ULS flat-four engine mounted in the nose, which drives a three-blade propeller. The tail assembly consists of a rectangular horizontal stabilizer positioned far aft; the ViS-3’s elevators were initially mass balanced but were refined on the ViS-5 variant to incorporate aerodynamic (horn) balances and slightly increased span. The vertical stabilizer comprises a tall fin and rudder with straight edges that are swept back; the rudder includes a prominent trim tab. The fixed tricycle landing gear employs spring cantilever main legs along with a cantilever-mounted, castoring nosewheel.

Variants

According to Jane's All the World's Aircraft 2013-14, pages 656–657:

ViS-3

The initial prototype, which had its maiden flight on 8 October 2006.

ViS-5

The production prototype featuring straight wings equipped with flaps and a wingspan reduced by 75 mm (3 in) compared to the ViS-3, while its length increased by 145 mm (6 in).

KhAZ-30 (ХАЗ-30)

The designation assigned to the production model. This version is 80 kg (176 lb) heavier when empty and has a fuel capacity that is 16% larger than that of the ViS-3. It was publicly unveiled on 22 May 2012.
