Antonov An-72. A photo. Characteristics
An-72 (NATO code: Coaler - «Collier») - Transport military plane. Designed in the design bureau to them. OK Antonov aircraft to replace the An-26. Armed with the air forces of Russia and some other countries. Aircraft engines for specific placement of called "Cheburashka". There are civil variation.
Test pilot Maximov and S. M. Popovic in November 1983 years 72 the An-set world records for the highest flight altitude - 13410 meters, the height of the horizontal flight - 12980 meters for airplanes in this class.
Pilot test Gorbik SV 1985 year developed the AN-speed 72 681,8 km / h on a closed 2000-km route.

By design is vysokoplanom. There swept wing. The unusual placement of engines in nacelles at the top of the wing, push forward increases due to Coanda effect lift. When you reject flaps and slats jet stream, which comes out of the nozzle engines to the wing "sticks", flowing around the top of the flap and the wing without interruption, it accelerates the air flow over. According to the laws of aerodynamics increase in flow rate causes a decrease in the air pressure. And what is the pressure difference above and below the wing more, the lift is greater and accordingly improve runways and landing characteristics of the aircraft.

The development of military transport aircraft An-72, having a short take-off and landing, engaged in Antonov Design Bureau in the early 1970 of Under the plan, it was supposed to replace turboprop An-26. By air introduces a new technology for creating additional lift designed for passing gas flow nozzles under wing engine. The author of this idea was the chief designer OK Antonov. This principle is based on the so-called Coanda effect, which was discovered and patented back in 1932, the
At the initial stage of development was carried out solely on the initiative of the Design Bureau, then it has supported the headquarters of the Air Force. By approving the project in the Air Force and the MAP, the theme of the front vehicle light aircraft involved in the work plan of the Antonov bureau. The device is code "aircraft 200». Work on the creation entrusted to lead designer YG Orlov. They were on previously lined with the layout scheme, which identified a win-win option, and the other to the attention of designers virtually taken.
The aircraft has a great similarity with the American «Boeing» YC-14, however, denied that the creators of technology borrowing ideas from overseas counterparts, saying that such an arrangement is caused by the need to protect the engines against the admission of third-party items. However, critics of this subject found more similarities with the Soviet car "Boeing" is not only one scheme.
After purging in aerotrube theoretical calculations with expectations. Indicator lift increased by almost 20%. special natural stands, which examined the interaction of the engine, the flap and the wing were made. To increase the surface blown, made in front of the center-removal engines, nacelles gave back a form that "smears" the exhaust stream of gas over the wing.
An on-72 arranged vysokoplana type having highly mechanized wing and T-tail. Purge aerotrube showed the formation of vortices in the ground engages the wing and fuselage. Therefore, during the flight the plane could change the quality of control. In order to reduce the rate of harmful interference, empennage made T-shaped. It helps to improve the directional stability and the installation of a powerful keel.
Overall performance of the cargo compartment of An-72 - 9 2,2 mx mx m 2,15 The aft cargo door is.. He closed the ramp, descending to arrival inside the cargo cabin of self-propelled equipment. Move any cargo can be carried on the roller conveyors, which are installed on the cabin floor. The control cabin is sealed, equipped with air conditioning.
In the summer, the first 1977-72 AN at Kiev aviation plant was built. The first flight was conducted 31 August of the same year, the crew led by test pilot V. The Terek. Completely finished testing the program, we took the decision to start serial production of the aircraft at the Kharkov aircraft factory.
During the operation of the AN-72 20 installed more world aviation records.
