Optimizing The MRJ’s Aerodynamics Through Advanced Design

Posted by Shigeru Obayashi on Sep 18, 2017 10:00:00 PM

As new government regulations call for more environmentally friendly aircraft, aerodynamics will play a key role in how airlines build their fleets for the future. Powered by its advanced aerodynamic design, the MRJ’s best-in-class fuel efficiency and lower emissions make it fit for the future.

Mitsubishi Regional Jet Debuts at Paris Air Show with ANA Livery

Posted by MRJ News on Jun 15, 2017 11:47:58 AM

 


The Mitsubishi Regional Jet touched down in France 5:05pm local time Thursday June 15 at Le Bourget Airport for the 52nd Paris Air Show. As part of the preparations for this landmark air show, we went through the meticulous process of painting the All Nippon Airways livery on the MRJ’s third flight test aircraft debuting at the air show this week. ANA, one of the largest airlines in Japan, is the MRJ’s first customer and has placed orders for 15 MRJs.

Pushing the Flight Envelope

Posted by Jyou Nagao, Aircraft Loads Engineering Lead on May 26, 2017 9:48:22 AM

During the flight load survey tests, more than 250 pressure sensors and strain gauges affixed to the aircraft measured the maximum loads on its external surfaces and components. Throughout the test flights, the crew maneuvered the aircraft to reach specified G-loads, maximum rudder deflection, and roll and side slip thresholds as our engineers monitored the data and Japanese aviation authorities witnessed and approved the test via the telemetry room.

Flying Safely Beyond the Limits

Flying the aircraft at varying altitudes and speeds beyond maximum operation limits, the high-speed flutter test demonstrated sufficient margin on the normal operating envelope of the MRJ. Testing for flutter – a phenomenon that occurs when aerodynamic forces cause rapid self-excited destructive vibration – required a heavily instrumented aircraft operated by well-trained crew that was monitored by engineering specialists on the ground.

Flying While Frozen

Posted by Koki Fukuda, Engineering Lead - Ice Protection Systems on May 26, 2017 9:44:36 AM

In February and March 2017, Flight Test Aircraft 4 (FTA-4) performed initial natural icing tests based out of the Rockford International Airport in Illinois. This was the first off-site test campaign to collect data in these conditions.

Tests performed by a team of global specialists using dedicated flight test instrumentation obtained valuable data to analyze the airframe ice accretion and Ice Protection Systems performance. Guided by a meteorologist on the ground, FTA-4 flew through clouds with specific moisture content, water droplet size and temperature resulting in varied icing conditions to understand how the aircraft would perform and eliminate ice on the leading edge of the wings and engines during flight.

Meeting the Strength Test

Posted by Alex Bellamy, Senior Director - Program Management Office on May 26, 2017 9:32:00 AM

Required for all new clean-sheet design aircraft, the Full-Scale Static Strength Test ensures the aircraft’s ability to meet structural strength safety standards and comprises testing of the wings, vertical stabilizer and fuselage. The test rig, a system of hydraulic actuators positioned to distribute force across the airframe simulating operating loads, was designed and manufactured by Mitsubishi Heavy Industries at a facility near the Nagoya Airfield in the Aichi Prefecture, Japan.
