Yak-242 (MS-21) is a design unit of Russian medium-haul aircraft for the transport of passengers at close range. The operational use is planned for the beginning of the year 2016, and the mass production machine must enter the year 2017. The main competitor of the liner is a Chinese-made aircraft S919.
Brief history of the Yak-242 (MS-21)
Program design and manufacture of the aircraft involved Yakovlev Design Bureau in cooperation with the company "Irkut". In the initial stages of design it was also attended by OKB Ilyushin, but at the beginning of the year 2008 he left the project. TsAGI autumn 2010 years spent testing engine and air intakes, which are planning to establish at the passenger liner. These tests made it possible to work out the security mode of the power plant. As a result, TsAGI has developed a set of recommendations for the Yak-242 designers (MS-21).
In September 2011 years "Irkut" company management stated that will be created for customers vehicles that are equipped with 180 passenger seats, although earlier planned to manufacturers produce 150 area with seating. This is due to the fact that most customers prefer the machine with a large number of passenger seats.

In the summer of the year 2012 aircraft manufacturers signed a contract with Pratt & Whitney, which will supply the engine type PW1400G. They will be installed on the new liner, the first test flight planned for the year 2015. In addition, the machine type MS-21 there with Russian engines, which are referred to as PD-14. Aircraft with engines type plan to deliver to customers in Russia.
Assembling the first full aircraft MS-21 2014 was started in the winter, at the aircraft plant in Irkutsk. In the summer of the same year in TsAGI tests were carried out large-scale models. According to official data the first flight of the new airliner is scheduled for April 2016 years.
Design features of the Yak-242 (MS-21)
The designers of this unit have been developed three variants of the car. They differ only in the number of seats in the passenger cabin. The first option holds 150 people, the second - 181 man, and the third modification can mark 212 passengers. Machine version was developed with greater range, which has been increased by 1,5 thousand kilometers.
The machine has been manufactured as a monoplane low-wing. They are arrow-shaped, they are attached to two pylons of jet engines. chassis system consists of three pillars. Front support a managed type, moreover, all-wheel drive chassis are equipped with braking systems. With regard to aerodynamics body, it is similar to the given class of similar machines, but has some advantages in the sense that puts this unit is much higher other.
MS-21 wider in 11 meters, greatly increases the comfort in the cabin. In the design of the aircraft systems and the latest designs have been added that allow you to achieve high aerodynamic qualities. In the manufacture of the liner involves many new alloys and composite materials, thus reducing the weight of the machine, while the design does not lose its qualities. It should be noted that when using these materials, the machine becomes considerably less expensive to operate.
To create a wing to the airplane was created company "Aerocomposite", which has the best designers in the industry. Wings machines are made of composite materials. When ordering the MS-21 airplane you can choose the type of the passenger compartment and engine. As previously mentioned, the engine can be set foreign or domestic manufacturing. The first production aircraft Yak-242 (MS-21) are expected in the year 2017.
When making this machine a lot of benefits has been received over the devices of this class. Firstly, the domestic machine has ecological engines, excellent aerodynamic characteristics. The advantage over other machines is the relatively small weight of the aircraft structure. Second, this machine can accommodate a large number of passengers, and these indicators are not all the planes. Also, the ship has a large range of flight with relatively low fuel consumption. A wide body makes it more comfortable to place a large number of people. All of these benefits of the Yak-242 (MS-21) can save up to 50% of costs in comparison with similar devices from other manufacturers. The calculations can be seen that this unit will generate greater profits per year.

The manufacturer plans to carry out serial production of these machines in the number 72 copies a year. "Irkut" corporation plans to produce the model of the passenger aircraft for five years. To date, deliveries seen horizon to 2023 years. According to calculations of the manufacturers will start this project pays for itself with just 350-th machine. Manufacturing of parts and assemblies made simultaneously at several factories, but the final assembly - at the Irkutsk plant.
