After two decades of operations, airplanes of the An-32 family have proved to be reliable, easy to maintain, manoeuvrable both in air and on the ground. During this period over 350 aircraft were manufactured, and now they are operated in 22 countries. The total operational time of the vehicles produced exceeds 1,209,000 flight hours, or 1,079,400 flights.

The An-32 family comprises light transport multipurpose airplanes that can be delivered both in military and civil variants.

Their main purpose is to transport cargoes at short and middle-range routes.

The military transport An-32 (prototype) is designed for transportation, parachuting and landing of troops, military equipment and cargoes, as well as for transportation of wounded men.

The aircraft can operate in different climatic conditions, including hot climate of Africa (to +55?), in mountain climate of India and Latin America (up to 4500 m high). These airplanes can take off from paved and unpaved aerodromes and from limited runways. The whole An-32 family has a set of anticorrosion measures to protect the power units of the airframe, which allows secure operations in damp maritime climate.

Mechanization of handling operations and availability of a turbine-generator set for power supply and starting engine operation ensure the autonomous aircraft operation at poorly equipped aerodromes.

The undercarriage with low pressure tires and high position of engines allow operating the vehicles at unpaved aerodromes and landing strip.

The cockpit and the cargo compartment are hermetic and fitted with an air conditioning system. The split-type temperature control in the compartments ensures simultaneous maintaining in the cargo b compartment the temperature necessary for particular cargo and securing normal temperature conditions for the crew.

The An-32 includes the following necessary modern transport units:

• a big aft cargo hatch with a lift frame moving under the fuselage or grounding, which secures prompt loading and unloading of an airplane from an automobile.
• an upper cargo-loading device for loading and unloading cargoes of the weight up to 3 t
• demountable roller equipment that provide for transportation of palletized or platform packaged cargoes

Dimensions of the cargo compartment and hatches allow transporting bulky cargoes, self-powered wheel equipment and cars.

Demountable roller equipment allows parachuting of twelve small cargoes pallets of the weight 500 kg each, or different variants of modular pallets for large cargoes with the maximum weight of cargo with the platform and the parachute system equal to 3000 kg.

Relying on the experience of the An-32s operations we have developed a system of day flights in simple weather conditions at aerodromes with limited airborne approaches, which provides for shorter descend distance and time, climb in different modes of engines operation, including ground idling, and angle of bank equal to 45°.

We have conducted tests of equipping the An-32 with special equipment for warning the crew of the aircraft hunting by radar stations of land and air-based agents, as well as protection systems from missile hitting in infrared guidance.

In 1995 the Aviation register of the International Aviation Committee ( Moscow ) issued a Type Certificate 79-32B for a civil An-32B variant.

O.K. Antonov ASTC is constantly perfecting the An-32s systems, equipment, and maintenance, is developing various aircraft modifications designed for increasing flight and cost performance.

Extension of the service life of the engines AI-20D, Series 5 is made possible by less engine workload.

The needed mid-flight engines takeoff modes are limited up to the maximum mode (90? ±2?). The takeoff engines mode of 120?+4-2 is considered to be ‘a contingency mode' and it is envisaged to be used at a working engine in case of the other engine failure.

The contingency control system includes mechanical, hydraulic, and electric elements. To ensure the contingency control system functioning, designers have changed the engines control panel by intruding an additional liquid-operated thrust.

We have introduced a hydraulic network for control of the thrust with engine throttles, comprising an electrohydraulic valve and a hydraulic cylinder.

Our designers have also introduced an electric control system ensuring switching on the hydraulic gear in case of the engine failure and blockage of the main landing gear reduction.

The engine throttles can be manually moved to the contingency mode.

The perfected engine AI-20D, Series 5M possesses the following life times:

• till the first overhaul and the overhaul life – 4000 h
• the specified life – 20000 h

The modified An-32s, namely the civil An-32B and the military An-32V, are fitted with perfected airborne equipment for pilotage by two crew members. This equipment includes: an indicator of the hazardous ground proximity speed, navigation and landing equipment, automatic radio compass, meteorological and navigational radar, radio stations of the microwave and UHF band.

The aircraft is also equipped with a satellite navigation system connected with the pilots' navigation flight device, radio buoy.

The two-pilot cockpit can be perfected in more profound and expensive way, based on the Rockwell-Collins equipment, including:

• a screen identification system, EFIS
• a air navigation system, FMS
• an inertial navigation system, INS
• a satellite navigation system, GPS, or GlONASS (Ukraine)
• an airborne range-finder, DMS
• a navigation system, TACAN
• an air signals system, ADS
• wireless communication equipment

At the customer's request, we may install equipment with metric or Anglo-Saxon measuring systems.

Taking into account the operation equipment and relying on the research conducted, the designers have developed a modification with the increased takeoff weight and payload:

• max taxi weight, 28750 kg
• max takeoff weight, 28500 kg
• max landing weight
• – for a normal landing, 26400 kg
• – for a crash landing, 28000 kg
• max payload, 7500 kg

The maximum takeoff and landing weights are determined according to real conditions by the flight manual.

Under the Customers' wish, we have developed a modification fitted with the engines Allison AE2100D, the propellers Dowty Aerospace R391 and the auxiliary power unit Sundstrand APS1000. Such engines and propellers are installed at the C-130J. We also conduct developmental work for the engines PW-150A.

On the contrary to the layout with the engine Ai-20D, the nacelle layout with the engines AE2100D (or PW0-150A) is performed featuring the engines arrangement, that is lower than the wing level. The nacelle midship is reduced by 20%, and the wetted surface is enlarged by 2%.

The engine and the propeller axle is installed at angle of 4.5? to the wing chord in the engine seating.

Using air from the auxiliary power unit in the air conditioning system allows:

• increasing comfort in the cockpit and the cargo compartment while the aircraft remains on ground with idle engines
• increasing the aircraft ceiling during a single-engine flight
