A Conversation with Hiroyasu Aruga, the Designer Behind the MRJ

Posted by The MRJ Team on Jul 2, 2018 8:22:18 PM

The Mitsubishi Regional Jet is the first entrant in a new class of higher performance regional aircraft. As the only clean-sheet aircraft for the sub-100 seat category, the MRJ cuts a sharper silhouette than any other jet in its class with a more aerodynamic nose, sleek fuselage and lean wings featuring optimized nacelles.

The man behind the distinct design of the MRJ, many aspects of its interior cabin and its advanced flight deck is Hiroyasu Aruga, a Technical Supervisor & Chief Researcher in Mitsubishi Heavy Industries’ Research & Innovation Center.

2017: A Year of Progress for the MRJ

Posted by Alex Bellamy, Chief Development Officer on Jan 4, 2018 7:02:13 PM

In 2017, the MRJ development program made significant strides. A re-organization at Mitsubishi Aircraft Corporation offices earlier last year strengthened program teamwork, which led to notable testing progress and a successful debut at the Paris Air Show.

While the MRJ continues on its path toward type certification, we take a look back at the important milestones the program has achieved in 2017.

Inside Moses Lake, The MRJ’s U.S. Flight Test Center

Posted by The MRJ Team on Dec 7, 2017 12:32:58 PM

It’s a sunny and hot July afternoon in Eastern Washington, and Kenji Okimoto is racing down the runway of Grant County International Airport. Okimoto, a vice president at Mitsubishi Aircraft Corporation America who runs operations support at Moses Lake Flight Test Center, is looking to position himself near the right runway so he can take a group of guests to observe today’s take-off of the Mitsubishi Regional Jet (MRJ). Air traffic control switched the runway due to a change in the wind conditions.

MRJ Conducts Hot Weather Test Flights

Posted by Katie Woods, Lead Engineer on Sep 22, 2017 1:33:43 PM

At Phoenix-Mesa Gateway Airport in Mesa, Arizona, Flight Test Aircraft 4 (FTA-4) once again donned its black mask to continue with extreme temperature tests. FTA-4 was deployed in August and spent multiple days in the Arizona heat operating in a maximum temperature of 42° C, or 108° F. Engineers collected data that will be used to further validate the performance of the aircraft's Environmental Control System (ECS), hydraulics system and powerplant.

Testing The MRJ's Cargo Smoke Containment Capability

Posted by Javier Aguado, MFC Engineering AMS Lead on Aug 10, 2017 9:40:58 AM

At the Moses Lake Flight Test Center in Washington, FTA-4 underwent cargo smoke testing between April 7 and April 22, 2017. To set up the test, engineers at Moses Lake installed a smoke machine and flexible hoses inside the cabin, along with lights, smoke detectors, and cameras to monitor real-time smoke generation. During the test, the hoses that were routed under the floor of the aircraft pushed smoke towards the test areas in the cargo compartment and the amount of smoke was controlled using the video cameras.

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.
