The MRJ Development Program by Mitsubishi Aircraft Corp. has been restructured, positioning to begin delivery of the first MRJ90 in mid-2020. Below, you will find a portion of their recent release covering the progress of the Mitsubishi Regional Jet.
To ensure the progress toward type certification, Mitsubishi Aircraft Corp. has restructured the MRJ development program and built one of the best teams in the industry, hiring many global engineers with experience in innovative commercial aviation programs to work alongside the Japanese experts in design and manufacturing. We are already seeing significant progress under this new approach, positioning the MRJ to successfully enter the market with type certification in 2019 and first delivery of the MRJ90 in mid-2020. Here is a list of a few recent flight and ground test accomplishments that are vital towards achieving certification.
Pushing The Flight Envelope
April 2017 Flight Load Survey
Results from the flight load survey test were expected and aerodynamic loads for each component fell firmly within the design limit loads. Completion of this test clears the aircraft to fly through its entire envelope, allowing pilots to fully exercise all control inputs. This vital test dictates the maturity of the aerodynamic design and confirms an aircraft can safely operate throughout its flight envelope.
Operating At -40 Degrees
Feb. 28 — Mar. 17 2017 Cold & Hot Soak
The results from this test have allowed our engineering teams to validate the thermal models and improve the design. Once environmental control system design improvements are implemented, the next steps are FTA-4 deployments to natural hot and cold locations to continue the testing and validation. Key tests at the Eglin’s Mckinley Climatic Laboratory evaluated the operational capability of airframe and system components, such as engines, in a broad range or temperatures ranging from extreme cold (-40 C) to extremely hot (50 C).
