Development reactive aviamashiny AN 72 was launched on its own initiative in 1972, KB DCAntonov.The lead designer was developing YGOrlov.In 1976, approved by the Government of the USSR № 558-186 on the production of AN-72 military transport type.New aviamashina should provide a short take off and landing.For this wing has been equipped with advanced mechanization.The lifting force of the wing on takeoff increased by blowing the exhaust flap jets coming from the jet engines, based on the Coanda effect.In an 72 used aircraft aerodynamic configuration cantilever vysokoplana having a T-tail.Solid metal construction is made of composite materials.The design has a sealed semi-monocoque fuselage of circular cross section and swept wing with a high aspect ratio trapezoidal plan.The mechanization of the wing used spoilers, slats, and double-slotted center-console trehschelevye flaps.
To ensure directional stability, the aircraft is equipped with a powerful keel.The rudder is made in the original double-hinged design that improves the efficiency of steering at high speeds.The very design of steering was divided in height into two sections.Management of the bottom of the rudder pedals the pilot carried out immediately, the rest - at the expense management system boosters.In order to reduce the effort in the management of a wide range of flight conditions and center, it was provided to the handlebars weight and aerodynamic balance.In the second unit of the rudder trim is placed, and the steering wheel height - trims and servo tab.Such a design solution has allowed the pilots to eliminate irregularities in the balancing of the aircraft when the mechanization of the wing.Due to the high location of the engine provides a protective function of the penetration of foreign objects, which is particularly important when bazirovke unpaved airfields.
designer of OKB DCAntonov built aircraft, which combines high enough quality flight and a small landing speed.An 72 piloting is simple and easy to control.The aircraft - the first and only domestic PTS, in a carriage which is not provided by the navigator.
Antonov 72, which allows a photo to see the ergonomics of the cockpit, equipped with modern equipment and has a low level of noise during the flight.The main distinguishing feature is the fact that having a normal take-off weight and load of up to 3500 kg, separation technology from the ground occurs when the speed level of 185 km / h with a running start just 420-450 m. The demonstration flight landing was carried out on the site ofsoil no more than 1,000 m, run at the same time was not more than 350 m.
Antonov AN72 aircraft used since 1987 in the Air Defense, Air Force, Navy aviation, MFD, the Strategic Missile Forces and border troops.With their help, self-propelled machinery of shipments and freight.The aircraft can transport up to 57 paratroopers or 68 soldiers with full equipment.Plane sanitary option enables the transport of 24 injured on stretchers and 12 seated.Production aircraft AN 72 was carried out until 2002.
