IL-103 is a multi-purpose four-seater aircraft. He was the first among these categories received a certificate of the Interstate Aviation Committee of the Commonwealth countries.
In 1988, the USSR announced a competition to develop the initial training aircraft. For two years, the team LA Pupkova designed air engine car with a car VAZ. The project was successful, but after studying the global market, the General Designer Novozhilov decided that the IL-103 need to install the engine type aircraft. At that point in the development of engines for light aircraft in the USSR was the only M-14, but it did not suit the technical characteristics. We asked for help to foreign firms. Help from the agreed "Teledyne Continental Motors" by setting the IL-103 motor IO-360ES. He had the power to 210 hp
Because of the new aircraft engine design we have decided to completely redo (for the period from 1990 1993 year). As a result, improved avionics and the appearance of the aircraft. Its layout shown at MAKS-93. 17 May 94 year rose in the sky the first prototype IL-103. He led I. Gudkov. In September 1994 the aircraft shown in Farnborough. For the aircraft immediately became interested in the representatives of England, the Russia, Ireland and other countries. The first demonstrations were very successful. Designers planned to complete certification in 1994 year and to begin mass production, and 95-m to prepare deliveries to customers. The building decided to organize the Lukhovitsy Engineering Plant.
However, the first production aircraft for reasons of poor funding rose in the sky only in late January 1995 years. Almost exactly one year later the aircraft was certified. Re-IL-103 demonstrated at MAKS-95.
The design of the aircraft IL-103
Air unit is made by a standard aerodynamic design, low located wings. Initially it was planned to construct it from aluminum, not composite materials. But now consider the possibility of adding to the material for certain components and mechanisms of composite materials.
Though the design is very simple, yet quite good flying qualities. Well-designed wing arrangement provides large bearing properties in the cruise configuration. it also accompanies static longitudinal stability preserve the same regardless of whether a positive or negative angle of attack. It should be noted that increasing the bearing plane on the positive properties of the corners is increased by the use of a rotary flap odnoschelevogo. Compared to cruising configuration during flaps critical angle of attack corresponds to the maximum positive value calculation lift. At the same time retained the static longitudinal stability of the machine with the flaps in a rather large range of angles of attack.
Control of the aircraft is very simple, because through the pedals and handles. Trigger to control the elevator is located on the control stick, which is very convenient for the pilot. On the left side of the cockpit is the handle extension and retraction of the flaps.
Maximum comfort is pilots also provided the possibility of adjusting the distance to the pedals. If necessary, according to the customer can be duplicated controls. A control handle itself can replace the wheel.
Regarding the fuel system designers using conventional tank layout and its components for this class of aircraft. First, fuel is placed in the wing tanks, compartments, and then it moves by gravity into the feed tank, from which the electric pump is supplied to the engine. Located on the tank 200 l can accommodate 150 kg of gasoline. The aircraft is charged through the wing filler neck.
At the heart of the power plant used American-made motor IO-36ES. On takeoff at 2800 revolutions per minute it develops capacity in 210 hp Cruising speed at revs per minute 2500 - 157 hp The engine six-cylinder with diameter and stroke 112,73h98,43 mm per hour, he will spend by up to 25 26 kg of fuel. The second unit is a two-blade propeller air HartzellPropeller 1,9-meter diameter.
Also optional on the plane you can set the Russian or Western piloting and navigation equipment.
The microclimate in the cabin of the aircraft is supported by the installed air conditioning systems. It also prevents fogging of glasses lamp chimney. The system is designed for three operating modes: ventilation, heating, recycling. The first is supplying air from the air intake system on the front glass. The second heats the air and delivers it to the lantern or glass, or on the bottom of the feet of the pilot and the passenger. recirculation mode is associated with feeding unheated air to the lamp glass. In addition, we established 2 individual ventilation openings.
The spring fixed landing gear, tricycle, with the presence of a nasal support. This aircraft can be operated in the GDP with a solid and lasting ground. If you use the fork damper on the front foot, setting the wheels on the axis of the aircraft takes place.
two versions of the composition developed navigation equipment for IL-103. The first concerns domestic equipment: FF-350, accelerometer, AGR-29, flashers, BP-30PB, ASF-1, a pointer to the height of the EBM-1PB, IZT9-1, VA-3, radio control board, the fuel pressure indicator, oil temperature and cylinder heads. The second option includes similar overseas equipment firm "Bendix King": artificial horizon 305-2V, giropolukompas, digital attitude indicator, Transponder 1A pointer glideslope VOR / LOC, navigation multichannel system "Laurent" Vario P / N 7060, turn indicators, speed and horizon.
On the main wheel hydraulic disc brakes installed. Also installed hydraulic braking system that has no overpressure source. In addition to the effective braking, it provides device control during taxiing on the runway.
Aircraft Electrical power supply system is provided with a voltage in 28 B. The main source of food it is a constant current generator. Also there is a backup power source. External radio provides a VHF radio, and internal discussions are due to internal telecommunication.
For the safety of the pilot and passengers meet established emergency rescue system. In the event of an air accident off the plane, you can use flaps lantern. The seatbacks parachutes deployed. Inside, there is a first aid kit.
IL-103 certified standards FAR-23 and AP-23 (IAC).
