Another achievement of the Sukhoi Design Bureau is the Su-80 model aircraft. This machine was designed in two versions: as a cargo and passenger car. The device of this type allows transporting 30 passengers, and the cargo model - cargoes weighing up to 3,3 tonnes. The range allows you to travel a distance of 1300 kilometers. The peculiarity of this machine is that it can be quickly converted from a passenger version to a freight one and vice versa. The cargo version allows transporting vehicles or containers with cargo, this was achieved by equipping the aircraft with a ramp in the tail of the car.

Brief history of the Su-80

Development of the Su-80 began with 90-ies of the last century on the initiative of MP Design Simonov. Initially, the plane was designed for military needs. the original shape of the car was formed over two years. This unit had to make the transport of goods and passengers on the lines of local importance. The main task of the designers was to manufacture a qualitatively new version of the aircraft, which could supplant the old, lower-quality models of the same type.


With this project, the 1993 interested in KnAAPO that Komsomolsk. Through this funding the manufacture of Su-80 was made by combining data and design bureau Sukhoi. This model was included in the all-Russian federal program that was supposed to produce a fully funded, but almost no funds received. Because of this fabrication machine has been delayed multiple times.

Features of the aircraft such as Su-80

The basic concept of the aircraft was originally conceived by marketing research on the aviation market in our country and abroad. In addition, a thorough analysis of the fleet was carried out to conclude what kind of car it is necessary at this point. All the work done was to lead to the fact that the aircraft will be in demand both in our country and abroad.

Su-80 type aircraft differs from its predecessors in flight efficiency and excellent characteristics. In addition, this unit can be used on unpaved runways, allowing it to land on virtually any surface.


In addition to efficiency in operation of the aircraft Su-80 has a very comfortable lounge for passengers. The passenger compartment provides maximum comfort when flying on any distance. This model has the capability of equipment for special purpose aircraft.

Design features of the Su-80

The Su-80 made under the scheme vysokoplana double-girder, which is notable for its economy, for which he received worldwide recognition in the aviation market.

Aircraft wings are designed for caisson type with one spar. Due to the elaborate work of designers managed to achieve excellent aerodynamics even at high speeds. Wings fitted with flaps, which are divided into three sections. Most wing machine parts made of composite materials. In the middle of the wing box located fuel tanks. In addition, the wing mounted landing gear, and, most importantly, they placed the engines of the turbofan type. All loading produced by the tail ramp, even landing passengers.

Su-80 cabin

All feathering device is made in the normal way, the elevators on the wings and rudder on the tail have trimmers and compensators. With regard to the chassis of the machine, it is composed of three poles, which are removed in the body of the aircraft. The front leg of the Su-80 controlled, but does not brake systems, in contrast to the two rear legs. In addition, the rear supports are equipped with additional cushioning systems that mitigate the impact when landing. The machine is equipped with tubeless tires. This type of wheel system helps to extend battery life.

As for the power plant, it should be noted here that the first model was planned to be equipped with a domestic production engine of the TVD-1500 type. But the development of this engine was delayed for a long time. It is for this reason that the power plant of the Su-80 airplane consists of engines of the type ST7-9V, produced by a foreign company. With take-off, these engines produce power in 1750 horsepower each. The choice of this engine was the right decision, because it is distinguished by its reliability and high efficiency, which is important in our time. At the moment, engines of this type are manufactured in Russia, at a joint venture in Rybinsk.


This kind of engine meets all quality standards and adapted to work in the domestic fuel and oil. The power plant is equipped with an automatic fuel supply and analysis of all of the fuel equipment. All engines of the aircraft SU-80 equipped with screws, which have four blades. They are made by reversing type, and also provides for a system that provides feathering in emergency situations. sinhrofazirovaniya system reduces noise effects when flying at cruising speed.

aircraft navigation equipment has been specifically designed for the model of Su-80 by special order at the enterprise "Electroavtomatika". This equipment has the ability to communicate with the satellite, which greatly simplifies the work of the pilots. Our equipment is high quality, but at the customer's request the machine can be equipped with more sophisticated navigation devices of foreign manufacture.

In addition to standard machines such as the Su-80, today manufacturers are ready to offer new versions of the aircraft, which are designed to perform a specific task. The new machine generation Su-80 can be such special machines as medical, landing, patrol (with the equipment of the "Swift"), training, as well as numerous other modifications.


Su-80 (S-80) - aircraft for regional and local airlines developed by the Sukhoi Experimental Design Bureau. Developed Su-80P (passenger version) and Su-80GP (cargo and passenger version).

The plane has a sealed cabin. It is designed to transport thirty passengers or up to 3300 kilograms of cargo over a distance of up to 1300 kilometers. One of the characteristics of the aircraft is convertibility, that is, the ability to quickly convert from a cargo version to a passenger one and back. The presence of a cargo ramp makes it possible to transport standard aviation containers and vehicles.

Runway data and chassis with low-pressure tires enable the use of smaller aircraft on airfields, including dirt, ice and snow-covered. The aircraft is equipped with two turboprop engines from General Electric ST7-9V capacity of 1870 horsepower. Certification Standards AP-25 airworthiness was planned. It was not completed due to the actual completion of the program.


Su-80 exhibition


It was intended to replace the An-26, An-24, Yak-40.

The aircraft is a twin-boom vysokoplan normal aerodynamic scheme with straight wings with advanced mechanization and high aspect ratio. U-shaped tail feathers formed stabilizer and two keels on the beams that close the power circuit.

The fuselage of the aircraft is an independent module with attachment points for the wing, the front landing gear and the supporting pylon. The beams house the engines, aircraft systems and equipment compartments, and the fuselage contains the flight deck, radar compartment, cargo-passenger cabin and avionics compartment. Tricycle landing gear, retracts in flight, equipped with a nose wheel. Disembarkation - embarkation - passengers and unloading - loading of goods is carried out through the ladder - ramp located in the tail of the fuselage.

Pleased with the sweep of the wing in 30 degrees! Straight MiG-15 of some kind ...

It is unclear why, together with the Chinese to build a regional airliner, if you already have a domestic long-flying Su-80, which has repeatedly demonstrated at MAKS.

For me, the Su-80 just super plane. I read a very - a lot of reviews and some are trying to lower not only the car, but its producers. I totally disagree with that, su-80 wonderful machine and it seems to me that the best aircraft will not be able to invent.

I want to share my opinion about the unusual project of the Sukhoi Design Bureau - Su-80. I, as a person who graduated from the MAI, seemed interested in this type of air cargo transport, as he was going to claim a niche that was occupied by such legendary aircraft as AN-24 and Yak-40. Therefore, comparisons can not be avoided. First, the appearance of the offspring of Sukhoi differs greatly from the standard appearance of the AN or Yak. The plane considered by me was in the form of a two-beam vysokoplana with a U-shaped tail empennage, which in itself is knocked out of the framework of the usual ideas about airplanes. Also the plane surprises with the way of loading passengers into the plane. In order to get into the salon, it's enough to pass along the hinged ramp, while for the rallying of competitors' cars you need to use special ladders. However, Su-80 loses to competitors in cargo capacity and capacity - 30 passengers in the cabin "dry" against 52 and 40 people in AN-24 and Yak-40, respectively. Because of this, the Sukhoi Design Bureau project was curtailed. By the number of modifications it can be seen that the designers tried to adapt this aircraft to different purposes and somehow succeeded, but this car could not occupy the niche of passenger aviation, since it was inferior to competitors, which dominate the market of passenger transportation, by the most significant characteristics.

Su-80 for me is a good machine. And by the way, no, I hold this view. I flew on this plane many times and never complained nor comfort nor convenience or to land or take off. If I still have to fly, I would like to take a flight with this aircraft.

And when he made the first flight?
