Bombardier versus Mitsubishi Regional Jet

Mitsubishi Regional Jet:

Canadian aircraft manufacturer Bombardier blamed the aircraft division of Mitsubishi Heavy Industries Ltd that former employees of Bombardier passed on commercial secrets to help the Mitsubishi Regional Jet regional jet project (MRJ).

The corresponding lawsuit in Seattle (USA) was filed on October 19, 2018 against Mitsubishi Aircraft Corporation, several former employees of Bombardier and Aerospace Testing Engineering & Certification Inc. (AeroTEC), which helps the Japanese manufacturer to certify a 90-seat passenger aircraft.

Mitsubishi Regional Jet:

At the Farnborough 2018 air show, the Mitsubishi Regional Jet was shown, for once. The aircraft was presented not only in a static parking lot, but also participated in demonstration flights. The aircraft is really very quiet, which did not go unnoticed by visitors of the cabin. To date, the prototype MRJ90 with a capacity of 88 chairs spent more than 2 thousand test hours in the air. It is planned that the MRJ will compete with the aircraft Bombardier CRJ and Embraer E-Jet.

The MRJ is a twin-engine regional aircraft with a capacity of 70-90 seats, being developed by the Japanese company Mitsubishi Aircraft Corporation, a subsidiary of Mitsubishi Heavy Industries. The division of Toyota, Fuji Heavy Industries and Subaru Corporation, which is a manufacturer of aerospace technology, also take part in the creation of the aircraft. The two main variants of the aircraft should be the MRJ 70 (with a capacity of 76 seats) and the MRJ 90 (elongated fuselage with a capacity of 88 passengers). Both versions will also have versions with an extended flight range of the MRJ 70 / 90ER and MRJ 70 / 90LR. Today, the company calls the MRJ90 modification a priority, which is expected to receive a type certificate soon. Then, about a year after the first delivery, the MRJ70 version will also be launched (from 65 to 75 seats).

Mitsubishi Regional Jet:

Japanese developers, with all the technological development of the country, clearly lack the experience in the development and production of civil aircraft. After all, the MRJ will be the first airliner designed and manufactured in Japan since the NAMC YS-111960s. From this and the process is very slow, with a lot of constant improvements. Especially difficult is the certification process. However, this does not in the least detract from the merits of Japanese engineers and does not exclude the successful bringing of the aircraft to mass production.

At the air show in Le Bourget-2017 for the first time a flight copy of the MRJ90 was demonstrated. The starting customer for MRJ is ANA (All Nippon Airways). Mitsubishi predicts that over the next 20 years will require 5,000 regional aircraft with 70-100 seats. The company expects that about 40% of all orders will come from the United States and a significant part from Europe and the United Kingdom.

Mitsubishi Regional Jet:

The developer claims that the combination of the PW1200G engine and the aerodynamic design is one of the advantages of this aircraft: “The new PurePower Geared TurbofanTM technology has improved aerodynamics, a larger wing extension significantly reduce operating costs, fuel consumption is reduced by about 20%. The architecture of a turbofan engine (Geared Turbofan Engine) uses 60% less turbine blades than conventional turbofan engines, which significantly reduces maintenance time and cost. New engines and improved aerodynamics help the MRJ achieve a 40 percent reduction in noise exposure compared with similar aircraft. ”

Aluminum and 10-15% composite materials are used in the design of the aircraft: the horizontal tail of the aircraft and the vertical tail. According to the developers, the aircraft has the widest cabin in its class. However, background information tells us that the width of the cabin is 2.76 meters. The Japanese aviation concern plans to locate 4 passenger seats in a row, which will make it possible to install slightly wider and more comfortable seats. In the passenger cabin of the test aircraft presented at the air show, instead of the seats, the equipment for flight tests was installed.
