Yak-42D - short-haul passenger aircraft: characteristics and reviews

There is a great variety of domestic planes, which every day rise in the air above our country, and not all of them are equally familiar to the townsfolk. So, very few people know about the Yak-42D model. The car is unique, deserves close attention.

Yak-42 in our days

The plane costs on servicing flights of Saratov airlines. There is nothing surprising, it was in Saratov that the construction of this transport was set up in due time. In addition to the Saratov air transport hub, the Yak-42D is seen in Domodedovo. The aviation company has 14 cars in its fleet, 4 on storage.

Transportation is in the parks of companies:

• "KrasAvia";
• "IzhAvia";
• "Tulpar-Air";
• "Terrible Avia";
• Ministry of Emergency Situations of the Russian Federation.

There was a Yakut (aircraft) and in service with Gazprom Avia, but recently the company completely abandoned its use. Several cars fly even abroad: in China, Pakistan and Iran, in Cuba.

Facts from history

Yak-42 from the Yakovlev Design Bureau was developed from 1972 to 1980. The aim was to replace the TU-134 - a good, but rapidly aging aircraft. 1988 was marked by the start of the serial production of a new model - Yak 42D. The car won with increased take-off weight and a long flight range.

The industry produced 183 aircraft of this modification. Two of them were designed for strength tests. 11 are constructed in the interval 1977-1981. At the aviation plant in Smolensk, 172 manufactured at Saratov Aircraft Plant. Yak - the plane is reliable, but its construction was stopped. This happened in 2003. The already prepared fuselages of planes, which were not destined to go to the runway, were sawed for scrap.

Since the task was to make the Yak-42 as a short-haul passenger aircraft, it was designed with the expectation of various aerodromes. The vehicle does not need a long take-off path or a large landing area, which is typical for much more widely used Boeing and Airbus. The design allowed avoiding the use of an airfield gangway.

Aircraft Feature

In the Yakovlev Design Bureau, unique aircraft beams were designed. It is customary to call hangar workers slang at the slang. Serving such a board is a difficult task. As you know, Saratov Aircraft Factory first became bankrupt, then completely stopped. Obviously, the production, including repair kits, spare parts, is discontinued. But the love of his work helps mechanics to bring "Yaki" over and over again in a satisfactory condition - and the cars again leave for the runway.

If you read about Yak-42D reviews, it will leave the impression that the car is not too good, so stopping production is not such a bad event. It is often mentioned that transport in operation was uneconomical. Nevertheless, the prospects were not bad. The designers proposed the following steps:

• Replace the engine with a more efficient system;
• To install new equipment for aviation;
• Lengthen the case to accommodate more passengers.

The last sentence is implemented in the form of Yak-42M. The vehicle serves 168 customers during the flight.

However, to realize the idea failed. But the responses of those who are still able to fly to Yak-42 clearly say that the plane is still good, despite the obsolescence.

Interesting Facts

Yak-42 has atypical engines - the work is tuned without a reverse. This allows you to plant the unit at a very low speed, it does not need additional means of speed relief, except for the brakes built into the chassis, and the help of the mechanized wing.

In Georgia, in Rustavi, a plane very similar to the Yak-42 (a kind of transport YAK-40) was written off, converted and opened inside a kindergarten.

YAK-42D is reflected in the music. So, Sergei Minaev, writing a parody of a famous Swedish song, wrote the following lines:

"If airplanes do not fly in bad weather - it does not matter,

"Elah" can not, and "Yaki" - yes. "

And it's not empty words, because the requirements for the host site and weather conditions, "Yakov" is significantly lower.

Now this is no longer remembered, but decades ago there was a project of a transport aircraft based on the Yak-42.

Variety of models

Yak-42D aircraft characteristics vary slightly from assembly to assembly. This depends primarily on belonging to the class of aircraft:

• VIP;
• General assistance.

The key difference in the arrangement of the passenger cabin. The VIP package includes:

• Salon for meetings;
• Rest room;
• Salon class 1;
• Salon of accompanying.

For the main passenger, the rest room is equipped with a swivel armchair and a sofa for two seats, which can be expanded into a full sleeper. There is a working table (folds if necessary), a wardrobe and a private bathroom.

The special room reserved for meetings has 4 swivel chairs, they can be moved around the salon. There is a large table, two sofas, designed for 7 people. There is a video communication system and access to a satellite phone.

The salon of the first class is equipped with armchairs for two seats, divided into blocks. Total blocks 4. Between them are installed folding tables (two pieces). The accompanying group flies in a designated area, designed for simultaneous deployment of 18 people.

In the high-class Yak-42D aircraft, the cabin is comfortable for long flights, equipped with a buffet, kitchen equipment is installed. VIP equipment includes the latest equipment for navigation, piloting, as well as radio systems of the latest generation. YAK-42 is flying, equipped with domestic systems, there are cars with foreign control systems on board.

Step forward: YAK-42A

Development of the idea of the Yak-42D was to be Yak-42A. Serial production started in 1999. In comparison with the previous model improved:

• The left door;
• Noise absorption system;
• Altitude of the launch of the APU (a new level - 5 km);
• Flap fixing system.

The left door gave passengers access to traditional gangways and modern telescopic transitions established in almost all airports. The fixed position of the flaps improved the performance of the aircraft. Updates of navigation and pilot equipment made it possible to use the aircraft on routes inside and outside the country.

Yak-42D: technical specifications

The aircraft has the following parameters:

• Wing in the span of 34.88 m;
• The horizontal tail is 10.8 m;
• Length of the vehicle 36.38 m;
• In the parking lot height of 9.83 m.

The Yak-42D chassis is characterized by the following values:

• Track 5.63 m;
• Base of 18,786 m.

The airplane in the classical configuration is designed for the transportation of 120 passengers, VIP-version for one flight serves no more than 49 people.

From an airplane to a weather station

Yak-42D - serial, time-tested machine. This was based on the choice of designers, to whom the task was set to make a weather station capable of collecting data on weather in different points of the atmosphere. The reconstruction of the passenger vehicle involved the employees of the plant. Myasishchev.

The task required the removal of sensors on the surface of the aircraft, provided with reliable protection. In order for the plane to withstand all the research blocks, it was necessary to complete six pylons on the wings. The fuselage was covered with various systems, devices for reading information about the environment. Most of them are used in the work of the lidar, measuring how transparent the air is.

The total weight of the meteorological flying laboratory is 7 tons. In the team there is an operator, a leading journal and writing down what can be distinguished by human vision: atmospheric phenomena, features of the surrounding space. The field of view is expanded by blisters of plexiglas. Designers built them on both sides. Putting his head in the blister, you can see everything that is happening around the vehicle.

It would seem, why make a Yak-42D meteorological station? All the data can be obtained from the satellite, is it really necessary more? But the satellites fly strictly along a given orbit, at a high speed, at a great distance from the surface of the planet. But the plane is above a particular site, controlling the atmosphere. Data from the satellite must be checked in addition, but the plane allows you to obtain accurate information. These significant advantages have become the impetus for the development of a unique mobile weather station. Finally, the aircraft is equipped with a system of release of iodine silver into the environment, which provokes precipitation.
