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.

Operating at -40 Degrees

Posted by Kunihiko Mizuno, MFC Engineering Manager - Eglin Lead on May 26, 2017 9:47:34 AM

At McKinley Climatic Laboratory on Eglin Air Force Base in Florida, FTA-4 underwent extreme temperature tests between February 28 and March 17, 2017. After initial set up, temperatures sunk down to -40° C for five full days of extreme cold testing. Following this, the testing team removed their winter coats and swapped in their t-shirts, and ratcheted the heat up to 50° C for several more test days. Among other systems, the test and data gathered is used to validate the performance of the Environmental Control System (ECS). “Pull-Up” and “Pull-Down” tests, which begin in a cold or hot soaked condition, measured the ability of the system to control the cabin and flight deck to a comfortable temperature within a specified time.

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.
