Amphibian aircraft.

Long sea-coasts, abundance of rivers and lakes, coupled with other hard-to-reach areas in different regions of the world are the right places for the Be-103 light amphibian operation. A most attractive and universal feature of the aircraft is its ability to operate from both paved and unpaved runways, as well as from inland water reservoirs and offshore waters.

The aircraft is a low-wing monoplane featuring +-type tail unit consisting of vertical fin with rudder and horizontal allmoving stabiliser, and tricycle landing gear with nose wheel. The power plant includes two TCM IO-360 piston engines mounted on horizontal pylons on either side of the fuselage. The low wing creates a considerable aerofoil effect at takeoff and landing, thus ensuring a three-point skimming capability (planning step, starboard and portside centre wing trailing edges).

The Be-103 amphibian is designed for a variety of applications, namely:

  • passenger transportation and administrative and liaison operations;
  • transportation of small-sized cargo and mail;
  • emergency medical assistance;
  • forestry monitoring and water ecology monitoring with water sampling capability;
  • maritime border patrolling and air photography;
  • pleasure trips and tourism.

LAYOUT VARIANTS DESIGN

The aircraft is of riveted design, made of aluminum alloys with special rust-protective coatings to ensure operation in all climatic conditions. It also features titanium alloys, polymers and glass-reinforced plastics. The materials were chosen to ensure the required strength and weight characteristics, the set service life as well as given fire safety and survivability requirements. The airframe is a one-piece structure consisting of the boat, the centre wing section, the fin and engine pylons. The detachable parts include detachable wing sections (cantilevers), the horizontal stabiliser, the rudder and nacelles. The Be-103 systems and equipment comprises the fire-fighting system, the control system, the hydraulic system, the heating and ventilating system, the anti-icing system and the flight control and navigation equipment.

POWER PLANT

The Be-103 amphibian is fitted with two US Teledyne Continental Motors 210 hp TCM IO-360ES4 air-cooled piston engines. The power plant ensures reliable startup of engines in a wide variety of temperatures (from +45°C to –55° C), and provides for comfortable conditions in the cockpit, complying with noise and emissions requirements. The two engines allow flying at an altitude of 3,000 m at a speed of 240 km/h to the ranges of up to 1,180 km. The engines are operated along with the MTV-12 three-blade reverse-pitch propellers designed by MT-Propeller, Germany.

RADIO COMMUNICATIONSFLIGHT CONTROLAND NAVIGATION EQUIPMENT

Elements of the radio communications, flight-control and navigation equipment, as well as the aircraft systems control panels are accommodated on the instrument panel, the central, the upper and the side consoles in the cockpit. This equipment provides for self-sufficiency during flight preparation or aircraft maintenance, as well as VFR and IFR manual flight modes, in daytime and at night, in any season and any region of the world. Also, it allows fulfilling the following tasks: a 10-minute preflight preparation; continuous measuring of the aircraft present position, the set track angle and lateral deviation; ICAO Category I manual approach; measuring of the flight altitude, vertical speed and airspeed, and outside air temperature; indication and warning of operating limitations and critical flight conditions.

The Be-103 amphibian is equipped with the Bendix/King radio communications, flight-control and navigation equipment including:

  • KY 196A radio operating within the band of 118-136.975 MHz
  • KMA 28/29 intercom
  • C 2400L4VT magnetic compass
  • KR 87 automatic direction finder
  • KCS 55A compass system
  • KLN 94 satellite navigation system with 1,602-1,616 MHz
    frequency band
  • P/N 8000 airspeed indicator
  • AI-330 attitude indicator 

The following auxiliary equipment can also be installed:

  • RDR-2000 or RDR-1400 weather radar
  • KAP-140or KFC-150 autopilo
  • KRA 405 radio altimetert
  • KX 165 radio navigation and communication system, operating
  • KT 70 aircraft responder
  • KEA 130A aneroid altimeter
  • P/N 7040 vertical speed indicator
  • P/N 9551B gyro turn and slip indicator
  • 307FC outside air temperature indicator

The navigation system of the Be-103 aircraft comprising the KLN 89B satellite navigation system, the KR 87 radio compass, the KX 165 radio navigation and communication system and the KT 70 responder allows the pilot to find the actual position of the aircraft and pick up heading, take the bearings of radio stations and listen to weather reports and commercial radio stations

AIRCRAFT CABIN

The interior of the aircraft cabin, together with the heating and ventilating systems and furnishings, provide comfortable conditions for the pilot and passengers in various flight situations. The cabin's walls and ceiling are finished, and there's carpeting on the floor. The interior is provided on the individual order of a customer and according to his design. The access to the Be-130 is through the 1,300x900-mm hatch folding upwards in the front part of the cabin on the left. There is a ladder in the left wing leading edge extension just under the hatch to allow access for the crew and passengers both on the ground and afloat. The emergency hatch is on starboard. It has the same dimensions as the main one.
The cabin has a pilot’s seat and five passenger ones (two seats in a row with 200 mm central aisle and a 1,220 or 860-mm pitch of rows). A second control panel can be fitted as well. The cargo compartment is accommodated behind the back side of the cabin. There is a buffer shelf between the seats and the back wall with slots for food and dishes. The rear part of the cabin also houses elements of the electric power supply system and the temperature adjustment system. The volume of air fed into the cabin is not less than 100 kg/h, while the temperature inside does not drop below +15°C, with the heating system operating in a normal mode.
There is a life jacket under each seat for emergency escape when afloat.
The pilot’s work place has an emergency radio station and a portable fire extinguisher.

OPERATION AFLOAT

The sea-going capabilities of the aircraft ensure its operation in sea state 2 (with 0.5 m high waves). There are waterproof bulkheads separating the boat and the wing compartments to ensure floodability if part of the hull is flooded. The landing gear wells are also waterproof and are separated from the inside of the boat. The Be-103 can be operated both at berthed and free waters, using floating assets and without them. The aircraft can independently climb soft slopes on the shore and set itself afloat from the shore. The stationary slipway has winches that can be attached to bow snatch cleats or the stern lug to help climb or descend the aircraft. When afloat the aircraft can be tugged by a boat with the help of a special kapron cord. At anchorage the aircraft is moored with the help of the anchor tab attached to snatch cleats. The cabin houses seagoing equipment, including a drag-anchor, a heaving line, a boat hook and water-resistant gloves. Also, a special pump is provided to drain water out of the compartments.
