Mitsubishi Regional Jet MRJ

Mitsubishi Regional Jet (MRJ) is a turbofan regional airliner designed and manufactured by the Japanese aircraft manufacturer Mitsubishi Aircraft Corporation (founded in 2008, founded in 2008 by Mitsubishi Heavy Industries and Toyota Motor Corporation). it is the first passenger airliner constructed in Japan since 1965 since the program for the production of the 64-seat YS-11 aircraft created in 1962 ended after 182 such aircraft were sold.

The first overall aircraft models were presented by Mitsubishi Aircraft at the Paris Air Show in June 2007. In a press release for airlines, the aircraft was presented as the latest regional airliner, the production of which was planned to be deployed in 2012. The first operator was represented by the Japanese airline ANA.

In 2008, the Japanese government announced that a new VIP liner would be ordered to complement the Boeing 747 government liners – board No.1 and Boeing 777 models.

Initially, MRJ was supposed to be the first fully composite airliner with a share of carbon elements greater than that of the Boeing 787, however, over time, it was calculated that the creation and production of such a machine would become unreasonably expensive. As a result, Mitsubishi left only about 15% of the elements of the aircraft composite (mainly, these are the parts of the tail). The latest methods of processing metals and composites were applied, which, as planned, will improve the characteristics of the aircraft without exceeding the cost.

The assembly of the prototypes began in 2011. Especially for the aircraft, a new Mitsubishi Aircraft production site was prepared near Komaki Airport, Nagoya Prefecture. The plant, which will employ about 2,000 people, is capable of producing 10 aircraft per month.

Nevertheless, the lack of experience in creating airliners made itself felt – the last time Japan created a complete airplane in the late 1960s and this experience was unsuccessful – the YS-11 was unprofitable. Mitsubishi Aircraft repeatedly postponed the implementation of the program to the right. As a result, the first deliveries shifted from 2012 to 2017. The liner was officially rolled out in the summer of 2015.

The two main options for the aircraft should be the MRJ-70 (with a capacity of about 70 seats) and MRJ-90 (an elongated fuselage with a capacity of about 90 passengers). Both options will also have versions with increased range MRJ 70 / 90ER and MRJ 70 / 90LR. However, in the “comfortable cabin” passengers will have to sit with a 29 ”step, instead of the 32” step that has already become standard (for Boeings, Airbases, Embraers and Superjets)

On November 11, 2015, the Mitsubishi Regional Jet (MRJ) passenger airliner made its first flight. The plane took off from the runway of the airport in Nagoya and after an hour and a half successfully landed.

After the first three test flights (the last was carried out on November 27), together with the results of static tests, it was found that the MRJ requires glider strengthening and software updates.

The aircraft manufacturer plans to continue its test campaign in Japan, before the start of the next phase of test flights, which will be conducted in the United States in the fourth quarter of this year. In total, the test duration is estimated at 2500 hours and will be performed by a fleet of five experimental aircraft.

In December 2015, Mitsubishi Aircraft Corporation announced another delay, the third in the program, with the transfer of the first deliveries to the second quarter of 2018. For 2015, Mitsubishi Aircraft has a portfolio of 223 firm contracts and 184 options from airlines from Japan, the USA, and Myanmar. The first MRJ-90 for 88 seats will receive All Nippon Airways (ANA).

So far, air carriers, including ANA, US Trans State Holdings, SkyWest, Eastern Air Line, as well as Air Mandalay from Myanmar, have ordered a total of 407 aircraft (223 in solid orders and another 184 in backorder options). The largest order (for 200 airliners) was placed by SkyWest – the largest regional airline in the world.
