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.

Neutralizing a Lightning Strike

Posted by Toshihiko Nishimori, Engineering Manager - EME Group on May 26, 2017 9:39:45 AM

As a prerequisite to the type certification lightning test later this year, we completed an internal simulated lightning strike assessment on Flight Test Aircraft 5 (FTA-5) in December 2016 in Nagoya, Japan. To simulate lightning strikes, we applied a low electrical current to the aircraft, which produces a magnetic field around certain areas of the aircraft, such as the ports, engines and the edges of the empennage on the tail.

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.
