Viator V4 - Overview
Viator V4 is a high-wing tractor of a tail-aft configuration with a twin-boom carriage of gantry form tailplanes. The V4 developed as a multipurpose aircraft for use in different geographical and climatic conditions, generally corresponding to the operating conditions of aircraft of this class. Its normal engine is Lycoming IO-540 with 300 hp passport engine power.
This aircraft can to transport 5 passengers with luggage 50 kg at a distance of 1100 km or 660 kg cargo at a distance of 730 km. Cargo cabin structure is specifically designed for transport of full-size cargo. The V4 allows to transport standard palletized cargoes, a snowmobile or ATV, fishing gear and diving equipment, rescue kits and wrecking-medical equipment, scientific and measuring complexes or droppable cargo.

The basic configuration is equipped with Lycoming IO-540 engine, which allows to V4 develop speeds of up to 255km/h with payload 720kg.
Lycoming IO-540 engine Approved by FAA. Additional configuration with navigation and communication equipment is provided upon request.
V4 aircraft with the take-off weight 920kg and a powerful piston aero-engine in the basic configuration lifts cargo weighing up to 720kg and has delivery range of up to 900km. The fuselage is equipped with a cargo hatch with a ramp. In the passenger version the aircraft capacity is 5 people plus a pilot.
Possible Applications
Transformability and modularity of cargo-passenger cabin is provided structurally, including to replace passenger seats or a set of rigging equipment. Worked out options for the replacement of conventional wheeled chassis on wheels super low pressure for loose and water logged unpaved runways, as well as options with the chassis of the float, ski, float-wheel and ski-wheel types. Airplane equipped with a ramp to facilitate loading and unloading.
Thanks to the developed mechanization of the wing, the aircraft can take off and land on a relatively small of size landing grounds.
Passenger and cargo-passenger carrying operations at a short-haul and mid-range distance
Transportation of full-size cargo, baggage, mail, sports equipment
Aircraft special purpose when performing patrol and search and rescue flights

Further modification of the aircraft can be
Setting the floats (seaplane or amphibious modification)
Installing the «ski+wheel» langing gear
Installation of a set of on-board equipment according to the customer's specification
Modification with increased fuel capacity
Adaptation with the more powerful or the client's specified engine
Market assessment
Demand in the world, according to the analysis of the State Research Institute of Civil Aviation, estimated at 1,500 aircrafts of this class by 2030.
CIS market capacity is estimated at 300-500 aircraft.
The competitive effect of self-cost reduction will be noticeable with an annual production program of at
least 18-20 machines.
Certification of the type air vehicle is an independent investment issue.
We are ready to export manufactured aircraft designs and sell the license for their production.
Aircraft description
Fuselage
The fuselage structure provides approaches to aircraft systems and units, ease of boarding and exit of
pilot and passengers through the side doors, high-visibility cockpit, ease loading and unloading of full-sized
cargo.
Riveted all-metal fuselage (aluminum alloy) consists of a frame structure and a skinning. The cargo-
passenger salon is located in the middle part of the fuselage. Loading opening is located in the aft of cargo-passenger salon and equipped with folding load under-tail ramp as well as opening up tail cowl. The booms are an extension of the fuselage sidewalls.
Wing
The aircraft has a high wing, rectangular in plan, single-spar, with retractable slotted flaps. The wing butting to the fuselage at the nodes of spar and the rear wall. The wing equipped a maintenance hatches for maintenance located in it of units and systems.
Tail
The airplane tail unit has a gantry form and consists of the HTP and VTP. HTP has a rectangular shape in plan and consists of the stabilizer and elevators with a trim tab. The twin-tailed VTP has a oblique leading edge, trapezoidal at a lateral view and consists of two keels and rudders with trimmer.
Equipment
Navigation and communication equipment, flight mode control equipment, on-board equipment, appliances, avionics: basic configuration is provided, additional (expanding) and custom-made equipment upon request. Additional configuration with navigation and communication equipment is provided upon request.
